8080.
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.
Extended Capabilities Port.
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.
NZ.
386DX.
The 386 chip was the first to offer a possible 32- or 64-bit access to data. OS-2 2.x or higher and Windows 95 required at least a 386 CPU while Windows NT 4.x required at least a 486 CPU to run.
Trojan.
Typically it relies on someone emailing it to you, it does not email itself, it may arrive in the form of a joke program or software of some sort.

Point to Point Tunneling Protocol.
It is a protocol used to create VPN connections over the net.

Time To Live.
Time To Live specifies how many more hops a packet can travel before being dropped.
Bell Laboratories.
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.
Neon Lighting.
Neon lighting runs at a high voltage, typically above 1000 Volts. A fireman's switch protects a fireman from receiving a shock when a water jet is sprayed onto the installation. The switches are red, and mounted in a conspicuous position. (This is specified by IEE Regulations (Europe), SANS (South Africa), UK Electricity regulations and many Asian countries. I am unable to confirm other countries' requirements, so feel free to let me know.)
Network Interface Card.
A NIC is a Network Interface Card. Usually a card that is plugged into a computer's expansion slot.
Uninterruptable Power Supply.
An uninterruptable power supply (UPS) is a backup power supply, such as a battery, that provides emergency power in the event that power is lost from the main supply.
A search engine is a program that searches for Web documents with keyword (s) you specify. Yahoo!, Google, and AltaVista are just three examples of search engines that have been created to help you find information on the Web.
Late 1960s.
As surprising as its age is, the Internet was born from the U.S. military's need to construct a decentralized computer network that could withstand a nuclear war. The network was used and refined by universities throughout the 1970s and 1980s, but it wasn't until 1992 that the Internet was made available to the general public.
WordStar.
Before the invention of word processing and spreadsheet software, personal computers had little value in the mainstream business world. WordStar was used before the days of function keys and the mouse. It, instead, used a set of Ctrl and Alt key combinations to navigate and edit text documents.
Data Over Cable Service Interface Specification.
DOCSIS was developed by CableLabs. A standard set for Cable equipment to ensure compatibility across all DOCSIS networks.
