History of the computer Created by: Jackie 3rd period

One of the first computers In 1939, John V. Atanasoff and Clifford Berry developed the Atanasoff- Berry Computer (ABC) at Iowa State University, which was regarded as the first electronic digital computer. The ABC was built by hand and the design used over 300 Vacuum Tubes and had capacitors fixed in a mechanically rotating drum for memory. One of the first computers The z1 was originally created by Konrad Zuse in his parents living room it was considered the first electrical binary programmable computer

The Bug DeBug A Moth found trapped between points at Relay # 70, Panel F, of the Mark II Aiken Relay Calculator while it was being tested at Harvard University, 9 September 1945. The operators affixed the moth to the computer log, with the entry: "First actual case of bug being found". They put out the word that they had "debugged" the machine, thus introducing the term "debugging a computer program".

Begging of the internet Started off in 1969 by arpa For research and education and etc.

Analytical Engine. The Analytical Engine was, or would have been, the world's first general-purpose computer. Designed in the 1830s by the English mathematician

tabulating machine The tabulator was a counting machine.  It kept a running count of the number of cards with a hole punched in a particular position.  It had 40 counters and hence could simultaneously count the number of cards with holes punched in up to 40 positions.  An experienced operator could tabulate 50 to 80 cards a minute.  There was no printer.  The results of a tabulation had read on the counter dials and written down by hand.

ENIAC “ENIAC” is short for Electronic Numerical Integrator And Computer, was the first general-purpose, electronic computer.

program is a sequence of instructions written to perform a task for a computer.
