- C. August 21, 1980
- D. January 12, 1982
- Correct Answer
- August 12, 1981
ExplanationBefore IBM created its personal computer, two types of computer systems, Apple II and CP-M, dominated the microcomputer world. Neither of these systems were PC compatible, or Mac-compatible (the two primary standards in place today). The original IBM PC became a new standard in the microcomputer industry. Since then, hundreds of millions of PC-compatible systems have been sold, as the original PC grew into a large family of computers and peripherals. More software has been written for this computer family than for any other system on the market. - 1. The Central Processing Unit is an embeded chip that acts as the 'brains' of a computer.

Correct Answer: 8080
Explanation:
The Intel 8080 was a jazzed-up calculator chip. It was included in microcomputer kits which were little more than demonstration tools and did little except blink lights. Besides the 8080 chip, the Altair included a power supply, a front panel with a large number of lights and 256 bytes (not kilobytes) of memory. The kit sold for {$395} and had to be assembled.
Correct Answer: CO
Correct Answer: Extended Capabilities Port
Explanation:
An Extended Capabilities Port is about 10 times faster than the old standard one, but it is used the same way a regular parallel port is.
Correct Answer: A program that catalogs Web sites
Explanation:
Spiders are also referred to as "bots" or "crawlers," and constantly scan the Internet for new and updated Web sites.
Correct Answer: Bell Laboratories
Explanation:
The transistor, which essentially is a solid-state electronic switch, replaced the much less suitable vacuum tube. Because the transistor consumed significantly less power, a computer system built with transistors was much smaller, faster and more efficient than a computer system built with vacuum tubes.
Correct Answer: Fluorescent Multi-Layer Disc
Explanation:
A new type of disc developed by Constellation 3D Inc. These discs can hold up to to 140 GB of data.
Correct Answer: Cohen
Explanation:
1983 Fred Cohen, while working on his dissertation, formally defines a computer virus as 'a computer program that can affect other computer programs by modifying them in such a way as to include a (possibly evolved)copy of itself.'
