Lesson 17 WellsComputer Concepts BASICS 17 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

Lesson 17 WellsComputer Concepts BASICS 18 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

Lesson 17 WellsComputer Concepts BASICS Summary Technology is having a tremendous impact on education. Many people predict that technology will change the entire structure of education. The Internet and the World Wide Web are the biggest factors affecting education today. Some people predict an antitechnology backlash. Electronic commerce is the buying and selling of goods and services using the Internet. 19

Lesson 17 WellsComputer Concepts BASICS Summary (continued) Digital cash allows someone to pay online by transmitting a number from one computer to another. New jobs and new job categories are being developed because of the Internet and electronic commerce. Some technological advances are voice recognition, nonlethal weapons, space travel, flying cars, smart shoes and smart seats, clothes that fight odors, and electronic shopping. Computer crime has become a major problem, costing companies billions of dollars annually. 20

Lesson 17 WellsComputer Concepts BASICS Summary (continued) Computer fraud is conduct that involves the manipulation of a computer or computer data for dishonest profit. Computer hacking involves invading someone else’s computer. Sometimes it is done for financial gain and sometimes just as a prank. A computer virus is a program that has been written to cause corruption of data on a computer. To protect against viruses, install and keep an antivirus program running on your computer. Be sure to update it regularly. 21

Lesson 17 WellsComputer Concepts BASICS 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. 22
