Scientific Discovery and Technological Innovations (continued)

Nanotechnology relates to creating computer components that are less than 100 nanometers in size

Optical computing uses light beams for the internal circuits instead of electricity

Quantum computing uses the laws of quantum mechanics and the way that atoms can be in more than one state at once to do computational tasks

Work and Play

Technology is affecting the way information and money is transmitted

Electronic commerce, or e-commerce, means having an online business

The digital cash system allows someone to pay by transmitting a number from one computer to another

Work and Play (continued)

A computer network can be a vital tool for helping work run more smoothly

Groupware refers to programs and software that help people work together despite location– One of the more common types of groupware is

e-mail. Computers play an important role in our life

from ordering pizza to using the ATM

Technological Issues

Computers have made our daily lives much easier, but there are risks and problems

Plagiarism is presenting someone else’s ideas or work as your own, without authorization

Copyright is legal protection for authors of their creative works

Computer crime is a criminal act committed through the use of a computer

Technological Issues (continued)

Computer fraud involves the manipulation of a computer or computer data in order to obtain money, property, or value dishonestly or to cause loss– Computer hacking involves invading someone else’s

computer– A virus is a program written to cause the corruption of data – A worm makes copies of itself and slows down a PC– A time bomb causes damage at a time in the future– A Trojan horse is harmful software that does the unexpected– An e-mail virus uses e-mail messages to carry the virus

Technological Issues (continued)

Theft of computer time is a crime committed regularly in the workplace

Changing data before or after it is entered into the computer is called data diddling

Computer equipment and data are subject to hazards such as fire and flood

Illegally copying and using software is called software piracy

Working on computers for long periods of time can cause ergonomic-related health issues

Technological Issues (continued)

Information submitted on the Internet can be used in computer crime

The best way to protect data is to control access of the data, most often through passwords

Other security measures include using ID cards, firewalls, antivirus software, selective hiring practices, and data backups

Biometric security measures examine a fingerprint, a voice pattern, or the iris or retina of the eye and compare them against employee records

Summary (continued)

Computer security is necessary to keep hardware, software, and data safe from harm or destruction.

The most common way to control access to data is to use passwords.

Illegally copying and using software is called software piracy. It has cost companies millions of dollars in lost sales.

Laws have been passed in an effort to assist those who have been injured by computer crimes and offenses. Many computer crimes are difficult to prove and prosecute.
