THE DIFFERENCES BETWEEN ETHICS AND LAW

DEFINITION OF ETHICS
In general, ethics is a moral philosophy where a person makes a specific moral choice and sticks to it. On the other hand, ethics in computing means moral guidelines to refer to when using the computer and computer networks. This includes the Internet.
DEFINITION OF LAW
Law is a legal system comprising of rules and principles that govern the affairs of a community and controlled by a political authority. Law differs from one country to another. In the era of technology, computer law is needed to clarify goods or actions that fall under the computer law. Computer law refers to all areas in law that requires an understanding of computer technology such as hardware, software and Internet. Examples of laws of computing in Malaysia include the Malaysian Communication and Multimedia Act, the Computer Crime Act 1997 and the Telemedicine Act 1997.
WHY DO WE NEED ETHICS AND LAW IN COMPUTING?
Respecting Ownership
Respecting Privacy
Respecting Property
RESPECTING OWNERSHIP
We must respect ownership by not stealing other people’s work either by duplicating or distributing it. Duplicating and distributing copies of audio tapes, video tapes and computer programs without permission and authorization from the individual or company that created the program are immoral and illegal.
RESPECTING PRIVACY AND CONFIDENTIALITY
We should respect other people's privacy and confidentiality by refraining ourselves from reading their mails or files without their permission. If we do so, it is considered as violating an individual’s rights to privacy and confidentiality.
RESPECTING PROPERTY
Property here means ownership. Since an individual data and information are considered as property, therefore, an act of tampering and changing electronic information is considered as vandalism and disrespect for other people’s property.
SIMILARITIES BETWEEN ETHICS AND LAW
Both ethics and law are complimentary to each other and are made:
to guide user from misusing computers
to create a healthy computer society, so that computers are used to contribute to a better life
to prevent any crime
DIFFERENCES BETWEEN ETHICS AND LAWS
ETHICS
GUIDELINE - As a guideline to computer users.
MORAL STANDARDS - Ethical behavior is judged by moral standards.
FREE TO FOLLOW - Computer users are free to follow or ignore the code of ethics.
NO PUNISHMENTS - No punishment for anyone who violates ethics.
UNIVERSALS - Universal, can be applied anywhere, all over the world.
PRODUCE ETHICAL COMPUTER USERS - To produce ethical computer users.
IMMORAL - Not honoring computer ethics means ignoring the moral elements (immoral).
LAW
CONTROL - As a rule to control computer users.
JUDICIAL STANDARDS - Law is judged by judicial standards.
MUST FOLLOW - Computer users must follow the regulations and law.
PENALTIES, IMPRISONMENTS AND OTHER PUNISHMENTS - Penalties, imprisonments and other punishments for those who break the law.
DEPENDS ON COUNTRY - Depends on country and state where the crime is committed.
PREVENT MISUSING OF COMPUTERS - To prevent misuse of computers.
CRIME - Not honoring the law means committing a crime.
UNETHICAL VS. LAW BREAKING CONDUCTS
Unethical:
using the office computer to do personal things
reading your friend’s e-mail without his or her permission
plagiarising and using materials from the Internet for your class assignment without giving credit to the original author.
Law breaking:
sending a computer virus via e-mail
hacking into your school’s database to change your examination results.
selling pirated software in a night market

THE IMPACT OF ICT ON SOCIETY

FASTER COMMUNICATION SPEED
In the past, it took a long time for any news or messages to be send. Now with the Internet, news or messages are sent via e-mail to friends, business partners or to anyone efficiently. With the capability of bandwidth, broadband and connection speed on the Internet, any information can travel fast and at an instant. It saves time and is inexpensive.
LOWER COMMUNICATION COST
Using the Internet is cost-effective than the other modes of communication such as telephone, mailing or courier service. It allows people to have access to large amounts of data at a very low cost. With the Internet we do not have to pay for any basic services provided by the Internet. Furthermore, the cost of connection to the Internet is relatively cheap.
RELIABLE MODE OF COMMUNICATION
Computers are reliable. With the internet, information could be accessed and retrieved from anywhere and at anytime. This makes it a reliable mode of communication. However, the input to the computer is contributed by humans. If the data passed to the computer is faulty, the result will be faulty as well. This is related to the term GIGO.
GIGO is a short form for Garbage In Garbage Out. It refers to the quality of output produced according to the input. Normally bad input produces bad output.
EFFECTIVE SHARING OF INFORMATION
With the advancement of ICT, information can be shared by people all around the world. People can share and exchange opinions, news and information through discussion groups, mailing list and forums on the Internet. This enable knowledge sharing which will contribute to the development of knowledge based society.
PAPERLESS ENVIRONMENT
ICT technology has created the term paperless environment. This term means information can be stored and retrieved through the digital medium instead of paper. Online communication via emails, online chat and instant messaging also helps in creating the paperless environment.
BORDERLESS COMMUNICATION
Internet offers fast information retrieval, interactivity, accessibility and versatility. It has become a borderless sources for services and information. Through the Internet, information and communication can be borderless.
SOCIAL PROBLEMS
There are some negative effects of ICT. It has created social problems in the society. Nowadays, people tend to choose online communication rather than having real time conversations. People tend to become more individualistic and introvert.
Another negative effect of ICT is :
fraud
identity theft
Pornography
Hacking
This will result a moral decedent and generate threads to the society.
HEALTH PROBLEMS
A computer may harm users if they use it for long hours frequently. Computer users are also exposed to bad posture, eyestrain, physical and mental stress. In order to solve the health problems, an ergonomic environment can be introduced. For example, an ergonomic chair can reduces back strain and a screen filter is used to minimize eye strain.

COMPUTERISED AND NON-COMPUTERISED SYSTEMS

COMPUTER SYSTEM

A system is an arrangement of elements that when it is put together it becomes an organised and established procedure. A system typically consists of components connected together in order to facilitate the flow of information, matter or energy.

A computer system consists of a set of hardware and software which processes data in a meaningful way.

INDUSTRY WITH ICT
Computers and telecommunications industry became very opular and profitable since production can be increased through an all day operation.

COMMERCE




Commerce is an activity of exchanging, buying and selling of commodities on a large scale involving transportation from place to place.

COMMERCE BEFORE ICT
• Trading was made using the barter system and it was then later developed
into currency.
• Advertisement was in the form of word of mouth, billboards and printed
flyers.
• Trading globally was extremely slow, late and expensive. Traders had to find
ways to market local products in the global market.

The Evolution of the Computer

First Generation (1940-1956) Vacuum Tubes

The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.
The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951.

Second Generation (1956-1963) Transistors

Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.
Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology.
The first computers of this generation were developed for the atomic energy industry.

Third Generation (1964-1971) Integrated Circuits

The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.
Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.

Fourth Generation (1971-Present) Microprocessors

The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and memory to input/output controls—on a single chip.
In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh. Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.
As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.

Fifth Generation (Present and Beyond) Artificial Intelligence

Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.
