The History of the Computer
By: Tanner
6th period
First Computer
• The first computer was founded by David
Packard and Bill Hewlett in a California
garage. The first computer they produced
was the HP 200A Audio Oscillator.
Debug
• Debug was written by Tim Paterson to serve
this purpose in QDOS. IT was made for
computers to determine whether a program
is operating correctly
Internet
• The Internet was invented by a team of
experts in 1957 ,when Russia sent Sputnik1
into space , to protect against Soviet missile
attacks.
Analytical Engine
• It was invented by Charles Babbage
• It was designed as a special purpose
calculator
• It held 1,000 numbers of 50 decimals
each(20,7kB)
The Tabulating machine
• It was designed for summarizing
information an was developed to process
data for the 1890 U.S. Census
ENIAC
(Electrical Numerical Integrator And
Calculator
• It was invented by John Mauchly and John
Preper Eckert for the American Army for
calculating artillery-firing tables an ended
up weighing 50 tons.
Program
• It is instructions written to do a special task
for a computer
Transistors
• Almost everything is powered by a
transistor. They are better than tubes
because their lighter, more durable, smaller,
and stronger
The Microcomputer
• The first microcomputer was invented in
November of 1977 by Joe Felsenstein
• It had 16 k of RAM
What is the binary system?
• It is a decimal system that uses only 2
numbers 1 and 0.
• Every communication in your computer
uses this binary system and it looks like this
101011101001100011010
