computer ethics

Hello I'm your instructor for this module on computer ethics and policies after viewing and understanding this lecture the learner should be able to define ethics know the history of computer ethics differentiate between computer ethics and cyber ethics understand. 

What is considered to be an unethical behavior for a student or a teacher know the security issues associated to personal information on public computers understand safety measures for ethics define acceptable user policy define security policy and know the various factors which contribute to effective security policies the general.

Definition of word ethics define the elements important to humans morals if it could be referred to as specific values standards rules and agreements computer ethics are a set of moral principles that governs an individual or a group on what is acceptable behavior while using a computer one of the common ethic missed by many among computer ethics is violation of copyright issues duplicating the copyrighted contents without the author's approval accessing personal information of others are some of the example that call it's ethical principles now let us have a discussion on history of computer ethics computer ethics is a concept that is growing larger every day with new advanced technology computer ethics first came about in 1970s.
 As computers were becoming integrated into homes computers today are used in homes and schools and in almost every company this field has taken ethics to a whole new level especially due to the privacy issues found throughout various businesses this form of ethics is also now offered as a course to study at many universities around the world computer ethics include the various physiological aspects of ethics as well as the cyclone and sociological interpretations.
When the field was first discovered in 1970s applied ethics was used to describe the new concept at that time there was much controversy to what computers would bring to the society some thought that computers would create more ethical issues whereas other thought it would our so-called twist on old ethics in the 1980s the computer was thought to be the closest object to a universal tool available to individuals in essence the integration of the computer into everyday society was not easy the generation of computer was new as well as exciting but nobody had used it before including businesses and individuals there would have to be some form of ethical guidelines to using these new products that nobody had much experience with nowadays computer ethics cover a wide variety of topics such as computers in the workplace Computer Crime Professional Responsibility and privacy and anonymity do you know what is considered as an unethical behavior for students and teachers let us discuss some of them in details.

 I'll start with the first one that is digital plagiarism plagiarism is one of the major forms of academic dishonesty which has always existed in education including higher education for example assignments submitted by students may turn out to be copied from fellow students or could be taken over in part or in whole from existing published works the use of computers and internet added to the means that students have at their disposal to commit plagiarism however they make it much easier to do and much harder to detect the second act which is considered to be an unethical behavior is breaking copyright and software pepp throughout the society it is well known that the illegal copying of copyrighted media such as text music works movies and software programs is widespread moreover many people.

Who engage in such activity do not consider themselves to be doing something that is immoral this is certainly true for college students and this attitude of students seems to match developments in the current information age in which the internet increasingly functions as the most important information medium that people use the third unethical app is improper use of computer resources students and staff may have authorized access to computer.

Resources but then go on to use these resources improperly they may have a school or library internet account or they may use computer system computer network or computer software that is owned by the institution or they may use computerized services offered by the institution and do so in a way that does not meet the institution's standards of proper use of that particular resource for example students may use their student account to run their own internet businesses may open up a popular web site or service that generates much traffic download mp3 files staff members may use their institution server or computer system to download view or store content that is either illegal or against the school's policy or may spread computer viruses or worms so we have discussed some of the acts that are considered to be unethical use of computing resources now let us have some discussion on securing information privacy and confidentiality let us start with security issues.
Associated to personal information on public computers while using publicly accessible computers students or staff may unknowingly leave personal information on the public users such as cached web pages and cookies that are then available for inspection by others second issue is file sharing the computers that are used by student or faculty may contain software that allow files from computers accessible to other users on the campus network or outside without knowledge of the owner or they may allow files to be stored on a central server that are then accessible to others without their permission this could allow strangers to read these files that may contain personal information the third issue is school web pages and bulletin boards web pages maintained by the school by faculty or by students may contain personal information that may access the privacy of others likewise posting and reposting on bulletin boards or in other electronic forums may contain personal information of third parties for which no authorization has been given one should always remember the 10 rules of computer ethics number one is one should not use a computer to harm other people the second one is one should not interfere with others computer work number three is one should not snoop around in others computer files number four days.
One should not use a computer to steal the fifth one is one should not use a computer to bear false witness the sixth one is one should not copy or use proprietary software for which one have not paid the seventh one is one should not use others computer resources without authorization or proper compensation the eighth one is one should not appropriate others intellectual output the ninth one is one should think about the social consequences of the program returns and the tenth one is one should always use a computer in ways that ensure consideration and respect for one's fellow humans some of the rules that the individuals should follow while using a computer are the first one is do not use computer to harm other users do not use computers to steal others information do not access files without the permission of the owner [Music] [Music] do not copy copyrighted software without the author's permission always respect copyright laws and policy respect the privacy of others just as you expect the same from others do not use other users computer resources without their permission use internet ethically complain about illegal communication and activities the found two internet service providers and local law enforcement authorities users are responsible for safeguarding their user ID in passwords they should not write them on paper or anywhere else for remembrance users should not intentionally use the computers to retrieve or modify the information of others which may include password informations files etcetera now let us discuss some of the internet ethics internet ethics means an acceptable behavior for using internet this should be honest respect the rights and property of others on the Internet acceptance World Wide Web is not a waste while web it's place where values are considered in a broadest sense we must take care while shaping contents and services and we should recognize that Internet is not apart from universal society but it is a primary component of it sensitivity to national and local cultures it belongs to all and there is no barrier of national and local cultures it cannot be subject to one set of values like local TV channel.

A local newspaper and we have to accommodate multiplicity of uses precautions while using email and chatting Internet must be used for communication with family and friends we should not use the internet chatting for communicating with strangers and should not forward the emails from strangers and we must be children on risk involved by chatting or forwarding emails to strangers pretending to be someone else we must not use the Internet to pretend as someone else and fool others we must be children that fooling others and hiding your own identity is a crime avoid bad language we must not use rude or bad language while using email chatting blogging and social networking we need to respect their views and should not entice eyes anyone on the Internet and the same should be taught to the children's high personal information we should teach children not to give personal details like home address phone numbers interests passwords to anyone no photographs should be sent to strangers and this should be taught to hide personal details from strangers because it might be misused and shared with others without their knowledge while downloading Internet is used to learn about music video and games by listening to it and learning how to play games we must not use it for downloading them or share the copyrighted material same should be taught to children's and they must be aware about the importance of copyrights and issues of copyright supervision you should know.

What children's are doing on the Internet and the sites they are visiting on the Internet and should check with whom they are communicating look over their shoulders and restrict them browsing inappropriate sites parental involvement while a child is using the internet helps the children to follow computer ethics encourage children's to use Internet we must encourage children students and others to gain the knowledge from the Internet and use it wisely Internet is a great tool where one can gather information which can be used for learning access to Internet the Internet is a time efficient tool for everyone that enlarges the possibilities for curriculum growth learning depends on the ability to find relevant and reliable information quickly and is and to select understand and assess that information searching for information on the Internet can help to develop these skills since many sites adopt particular views about issues the Internet is a useful tool for developing the skills of distinguishing facts from opinion and exploring.

Subjectivity and objectivity now let us discuss what is cyber ethics cyber ethics is a code of behavior for moral legal and social issues on the Internet or cyber technology cyber ethics also includes obeying laws that applies to online behavior by practicing cyber ethics one can have a safer and enjoyable internet experience cyber bullying is the use of information technology to repeatedly harm or harass other people in a deliberate manner with the increasing use of these technologies cyber bullying has become increasingly common especially among teenagers cyber technology referred to a wide range of computing and communications devices from individual computers to connected devices and communication technologies cyber ethics suggest the study of ethical issues limited to computing machines or to computing professionals it is more accurate than Internet ethics which is limited only to ethical issues affecting computer networks cyber safety cyber safety addresses the ability to act in a safe and responsible manner on the internet and other connected environments.

These behaviors protect personal information and reputation and improved safe practices to minimize danger from behavioral-based rather than hardware or software based problems cyber security cyber security covers physical protection of personal information and Technology resources from unauthorized access gained via technology safety measures for ethics there are four effective approaches who want to ensure they are doing the right thing online the first one is have a basic understanding of the technology second one is participate with your child online third one is determined what standards have been established for any school computer use create a set of rules along with your child relating to both ethics and safety as per the importance of information technology and given the possibilities of unethical use of this technology by students and faculty student schools universities and colleges should ensure that they have policies regarding the use and management of information technology by students and staff several ethical codes dealing the technology used exist and many schools have adopted acceptable uses policy that includes rules for the proper use of information technology teachers students and parents need to know and understand these ethical codes for children's the major issues surrounding technology ethics can be categorized into three areas privacy property and appropriate use schools related cases can be found in each of these areas.

Teachers need to develop learning objectives and activities that specifically address technology ethics proper use need to be taught at the same time that other computer skills are taught students understanding of ethical concepts need to be assessed technology use privileges especially those involving online news should not be given to student until the assessment shows that a student knows and can apply ethical standards and institutional policies in institutions one should have an acceptable user policy an acceptable user policy that describes the use of internet and other information technologies and network in an institution the rules in these policies often apply to both staff and students everyone in the institutions as well as parents need to know and understand these policies an acceptable user policy may contain not using the service as part of violent in any law not attempting to break the security of any computer network or user not posting commercial messages to institutional groups without prior permission not attempting to send junk email or spam to anyone who don't want to receive it not attempting to mail bomb aside with mass amounts of email in order to flood their server do not use computer technology to cause interference with other users work do not use computer technology to steal information organizations are becoming increasingly sophisticated in the way in which they organize and use information technology they are spending too much on IT just to take benefits from the latest technologies and to boost their businesses and grow leaps and bounds we can see it around us in real time now for booking a cab we rarely have to tell that cab driver our pickup address manually app detects it automatically most of the providers use location-based system or GPS to track the user and set the address as a pickup location it is just matter of minutes that booked cab arrived at your place people have never thought of these ten years ago even organizations are using technology this much still most of the organization are not having dedicated budget for security as they don't see any direct return on investment.
Once organization goes through major attack then they start thinking about security and start spending budget on security things as a part of company people should be aware of their security responsibilities for proper security in organization people process and technology should be focused area of improvement in these days employees are most targeted because they are easily exploitable now one question may in your mind where to start insecurity if organization want to secure their asset so what should be the starting point of that particular organization yes you are right there should be some policy document which should be followed and in this document it should also be mentioned that what will happen if this particular document is not followed now let us start with defining policy first policies are high-level document to represent corporate philosophy of that particular organization policies are kept more clear and concise to keep them effective basic elements of a policy are purpose scope responsibility and compliance policies are set up with the objectives of reduced risk compliance with law in regulation and assurance of operational continuity information integrity and confidentiality policies are also known to be the first layer of difference policies are important difference document for internal audits and for resolution of legal disputes about management's due diligence security policy is the statement of responsible decision makers about the protection mechanism of a company.

Crucial physical and information assets overall it is a document that describes a company's security controls and activities for an organization it addresses the constraints on behavior of its members as well as constraints imposed on adversities by mechanism such as doors locks keys and walls for system the security policy address constraints on functions and flow among them constraint on access by external systems and adversities including programs and access to the data by people the success of an information resources.

Protection program depends on the policies and on the attitude of the management towards securing information on system in order to produce a complete information security policy management must be three types of information security policy number one is enterprise information security program policy number two is issue specific information security policy and the third is systems specific information security policies in enterprise information security program policy management establishes how a security program will be set up lays out the program's goal assigned responsibilities shows the strategic and tactical value of security and outlines how enforcement should be carried out and also provides scope and direction for all future security activities within the organization.
This policy must address relative laws regulations and liability issues and how they are to be satisfied it also describes the amount of risk senior management is willing to accept issue specific information security policies addresses specific security issues that management fields need more detail explanation and attention to make sure a comprehensive structure is built and all employees understand how they are to comply with these security issues for example an email policy might state that management can read any employees email messages that reside on the mail server but not when they reside on user's work station system specific information security policy presents the management's decision that are specific to the actual computers networks applications and data this type of policy may provide an approved software list.

Which contains a list of applications that may be installed on individual workstations for example this policy may describe how databases are to be used and protected how computers are to be locked down and how firewalls ideas and scanners are to be employed for making policy there are many factors which contributes the first important factor is gold gold addresses the important concerns light as the issue being adequately defined and properly framed how will the policy achieve the high level policy goals of the department and the government as a whole the next important factor is ideas idea addresses the important concern light as the policy process being informed by evidence that is high-quality and up-to-date as the account being taken of evaluation of previous policies has there been an opportunity or license for innovative thinking have policy makers sought out and analyzed ideas and experience from the front line.

Overseas and devoted administrations the next important factor is design design addresses the important concerns like have policy makers rigorously tested or assess whether the policy design is realistic involving implementer and the end users have the policy makers addressed common implementation problems is the design resilient to adaptation by implementer another important factor is external engagement and it addresses the important concerns like have those affected by the policy being engaged in the process have policy makers identified and responded reasonably to their views next is appraisal it is concerned about the important issues like have the options being robustly assessed are the cost effective over the appropriate time horn are the resonant to changes in the external environment have the risk being identified and rated fairly against potential benefits next is rules and account abilities it is concerned about important issues like have policymakers just the appropriate level of government enrollment is it clear who is responsible for what who will hold them to account and how next is feedback and evaluation it is concerned about important issues like is there a realistic plan for obtaining timely feedback and how the policy is being realized in practice does the policy allow for effective evaluation even if government is not doing it last but not the least is the policy is read by the targeted staff or the audience policies are only useful.

If the people for whom it's targeted read those policies it's effective when people read the policies and understood those policies people should be agreed to the formulated policies then only they will be effective as in this dynamic environment upon the need policies should be updated from time to time if required to make them effective so in this lecture we have discussed about computer and cyber ethics and security policies I hope these concepts are clear in your mind now thank you you.

what is the importance of Mathematics in Computer Science?

what is the importance of Mathematics in Computer Science?


Mathematics has been the scourge of the many students’ lives (including mine!!!) since arguably it’s origination. On the opposite hand, engineering is sort of attention-grabbing and students study it in hopes of turning into successive programming whizz-kid!!! however hold on…is it very that simple?!! No, my friends, it isn’t….Computer Science is in truth quite closely connected to arithmetic.

For many years, there has been a lot of discussion regarding the Importance of arithmetic in engineering. Some believe that it adds solely very little worth in engineering whereas others (mostly within the majority!) suppose it's the inspiration on which pc Science is constructed. per the University of Oxford:

Mathematics may be a basic intellectual tool in computing, however computing is additionally more and more used as a key element in mathematical problem-solving.

Even if arithmetic has such value…the question still stands “Why is arithmetic thus vital in laptop Science?” thus let’s specialize in that currently.

Why is arithmetic thus vital in laptop Science?
Imagine the Burj Khalifa (Tallest Building within the world). Now, what's the foremost vital a part of this building? No, not it’s not the peak (well, that too!) however chiefly its foundation. If the Burj Khalifa didn't have a robust foundation, it might are fairly wobbly and far additional seemingly to fall than stand!!

Now, just in case you're speculative regarding this off-topic story, arithmetic is that the foundation on which pc Science is constructed (Burj Khalifa…get it?!). In fact, it will even be aforementioned that engineering is that the set of Mathematical Sciences generally. however so? 

1. separate arithmetic is that the Foundation of engineering
Ever detected of Logic Notation, Set Theory, Combinatorics, Graph Theory, likelihood, variety Theory, Algebra, etc.? Don’t be swamped, these are all a region of separate arithmetic and additionally a basic foundation for Programming and engineering (And meaning you wish to review these for laptop Science!!!).

A prime example of this is often pure mathematics. whereas Boolean logic is employed in Logic Gates, relative pure mathematics is employed in Databases. just in case you wish another example, variety Theory has multiple applications in Cryptography and cryptology. (See the importance yet?!)

2. arithmetic Teaches the Usage of Algorithms
Algorithms are a basic a part of engineering and every one of have to be compelled to} have detected of them a method or another (If not…you need to study again!!!). they're primarily a group of directions that demonstrate the implementation of a program or AN application.

Now, wherever did you initially use AN algorithm? it absolutely was not the pc Science category however really the arithmetic class! Don’t believe me?!! Well, “2 + 3 = 5” may be a basic algorithmic rule you learned in arithmetic category that demonstrates the total of two and three. arithmetic is truly vital in learning the essential usage of algorithms that are utilised in a sophisticated type in engineering.

3. arithmetic Provides the Analytical Skills needed in engineering
Analytical skills are necessary for problem-solving and information analyzation. And guess wherever you initially use these skills? Mathematics!!! yea, arithmetic continually forces you to investigate your equations and perceive the derivation flow just in case a blunder is created. this error has to be fastened so as to get the ultimate answer.

This provides scores of analytical skills that may be used later find and fixing bugs!!! even supposing there are trendy tools that can try this job mechanically, the expertise and data gained regarding the program flow and debugging is priceless.

4. Mathematical ideas are needed in several Disciplines of engineering
Computer Science is AN umbrella term that contains several disciplines like in operation Systems, Databases, Networking, computing, Embedded systems, information analytics….need i'm going on?!!! And whereas there are some disciplines that you just will handle with lowest data of arithmetic, most of them need a minimum of some level of competence.

For example, fields like computing and Machine Learning need a radical data of Mathematical ideas like algebra, Multivariable Calculus, applied math, etc. (And that produces Maths pretty important!!!)

So What’s the Conclusion?
Is arithmetic very necessary laptop Science? Well, some would say that it depends on the work. For Example: making a diary on food doesn't essentially need any data of arithmetic. however making a victorious diary is another factor entirely. It needs attention on audience preferences, topic quality, article ratings, etc. And guess what…Mathematics is needed for all of this.

So yes…Mathematics is gift within the foundation of engineering. And if you would like to achieve any discipline of engineering, it's far better to instill a love of arithmetic as which will assist you hugely.

Computers: Essay on Computers


Read this comprehensive essay on Computers !

Today’s generation would possibly ne'er ever imagine in their wildest dreams relating to the world, ages before, once there are no computers or the opposite technologies. such loads we've advanced that presently every knowledge is solely a click away and is in your hands 24/7. All this advancement was possible exclusively with the introduction of alittle device referred to as the “Computer”.
ADVERTISEMENTS 


Basically, portable computer is also a tool that accepts the message by the imputer Associate in Nursingd processes this message associated stores the information at the storage devices and later provides an output of the message through the output devices.

A simple rationalization of the laptop. Normally, a portable computer consists of a method unit referred to as the Central process Unit or the equipment and a sort of memory. among the years between 1940 and 1945 were the first electronic digital computers developed. The initial sizes were as immense as an area and consumed power the most quantity as today’s personal computers.

Initially, laptops belonged to a private administrative unit that demonstrated mathematics or mathematics, since the word computer was coined in 1613 and continued until the 19th century. It was later restored as a counting machine.

ADVERTISEMENTS:

The early computers were restricted in their functions. it fully was the fusion of automatic calculation and programmability that created the first computers that were recognized in 1837. Charles Babbage in 1837 was the first to introduce and magnificence a very programmed mechanical portable computer, his analytical engine. due to restricted finances and inability of resisting tinkering with the look, he couldn't complete his work and it fully was later completed by his son Henry Babbage administrative unit created it into a simplified version of the analytical engine’s computing unit.

The original objective of inventing a portable computer was to create a fast calculator. throughout the world War II, it became very essential to know and realize the direction and speed of the enemy weapons. Calculations had to be done accurately and mathematically and whereas not a classy machine it'd not be possible. To defend the enemy , the road troopers required firing tables and exclusively a portable computer would possibly prove such firing tables with speed and accuracy at that time.

At that time, a large amount of money and brain power was needed to develop the technology. The first laptop was developed by the United States under the name Moore's Engineering School, ENIAC. UU that was in 1946. The ENIAC was able to test the firing tables, which took careful account calculations.

Over a quantity of some time computers have evolved and toady with the imitative Intelligence technology, we've an inclination to use the foremost advanced quite computers that have helped man in every sectors of life. At every generations of the computers or very throughout the evolution, when computers are being launched that are lighter, smaller, speedier and extra powerful. The computers are a dominating issue since the 1970`s and lately it's conquered the bulk walks of life.

ADVERTISEMENTS:

Computers are becoming used for various functions lately like prediction, machinery operations, steering of satellite and technology. aside from these among the medical sector, it provides a wonderful assist in storing knowledge that may be referred later, in house technology, automation in banks, tag booking through web, control, and even games can be contend in computers on and many of further. of those are possible exclusively thanks to the characteristics that a portable computer posses like speedy, accuracy, reliability and integrity. it'd govt over a billion directions per second whereas not committing any mistakes is completely reliable. The memory of the laptop is so immense that it'd hold during a} very large indefinite amount of data.

To run a portable computer, it's the programming that decides and it need to be run during a} very portable computer. Programming is printed as a set of directions assigned  to the laptop that accepts it therefore on unravel a problem. There are many alternative languages that are becoming wont to program a portable computer. variety of the languages are BASIC, COBOL, C, C++, JAVA are some to decision.

With the introduction of computers, attaining knowledge has become an excellent deal further easier. Computers became the backbone of data Technology and a significant application throughout this sector is that the net. With cyber web, nothing isn't potential lately. aside from deed knowledge, one would possibly keep connected to friends and family, a wonderful platform for business expansions, purchasing, learning and so the list merely goes on, it's endless.

Computerization within the majority sectors, have created job gap for thousands. portable computer education has been introduced at school levels and in primary classes, as such is that the importance of deed the data of computers. once a year there are thousands of students exit from universities and faculties across the globe into the world of technology and this youth is what's tomorrow’s assets in getting technology into consecutive level of advancement.

ADVERTISEMENTS:

The computer has verified altogether roles that it's been appointed. a wonderful assist, in every sector that has been applied with computers. Telecommunication and satellite imaging are portable computer based totally, that's facet to the long list of applications portable computer holds in alternative fields.

With every positive, there's a negative and  same is applicable with computers additionally. With all the positives that one would possibly acquire and seize, the negative side is in addition large. the increase in Cyber crime, horny websites, false identity leading to paraphernalia of youngsters and many of further. Yet , the advantages are further outnumbered and there are many preventive measures in addition introduced to forestall the negative aspects.

The world wouldn't are what it's lately, had there not been Associate in Nursing entry to this nice machine despite the actual fact that among the crude kind, ages before U.S.. portable computer incorporates a pleasant future which we have a tendency to merely ought to keep a watch and mark the changes returning to it.

Together they faucet into "clinical Love" key fist Hold a "roll into" key "Home" Key and therefore the "Power" button

When you feel the phone vibrated obtaining hold of "Power" still press the key, however additionally "Volume" key and therefore the "Home" key.





3. So i am going bent on the tent, "Warning yellow triangle" is currently occupied
"Volume Up" key to continue.
Samsung and gleaming say - step a pair of




4. Now, transfer and extract "drowned" to your laptop. so let start your software Odin3 once aforsaid pc, .then connect it laptop.
