Vacuum Tubes and Valves

Vacuum tubes or valves were used in first generation of computers. Read more about Vacuum Tubes - what it is, how it works and what uses it.

Dumb Terminal

A type of terminal that consists of a keyboard and a display screen that can be used to enter and transmit data to, or display data from, a computer to which it is connected. A dumb terminal, in contrast to an intelligent terminal, has no independent processing capability or auxiliary storage and thus cannot function as a stand-alone device. 


Millisecond is smaller unit than second. 100 milliseconds make up a second. Read more about speed and space measurement units in eCourse.



ABC, the first electronic digital computer, was invented by John v. Atanasoff and his assistant Clifford Berry and thus the name Atanasoff Berry Computer (ABC).

Earlier, ENIAC was considered to be the first electronic computer until in 1973 a U.S. District Court invalidated the ENIAC patent. Thus, ABC is the first electronic digital computer. However, because ABC is a special purpose computer and not programmable, ENIAC is the first general purpose electronic computer. [Read more about ABC and how it works in ICT Trends eCourse]

Hard Disks

A hard disk drive (HDD; also hard drive or hard disk) is a non-volatile, random access digital data storage device. It features rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is magnetically read from and written to the platter by read/write heads that float on a film of air above the platters. [Read more on Wikipedia]

Address Bus

A collection of wires connecting the CPU with main memory that is used to identify particular locations (addresses) in main memory. The width of the address bus (that is, the number of wires) determines how many unique memory locations can be addressed. Modern PCs and Macintoshes have as many as 36 address lines, which enables them theoretically to access 64 GB (gigabytes) of main memory. However, the actually amount of memory that can be accessed is usually much less than this theoretical limit due to chipset and motherboard limitations. [Source WeboPedia]
