THE HISTORY AND TIMELINE OF COMPUTER

A computer is an electronic device that manipulates information or data. It has the ability to store, retrieve, and process data.
One can use the computer to type a document, send an email, edit photos and videos, etc. The computer is a very helpful device. It is
sought by many people. The humble beginnings and the development of the computer will be shown by this chart.
1943
1936

1942

Konrad Zuse

John Atanasoff & Clifford Berry
Atanasoff-Berry Computer (ABC)
Designed to solve systems of linear
algebraic equations

Z1 Computer
First freely programmable computer

1948
Frederic Williams & Tom Kilburn
Manchester Baby Computer & The
Williams Tube
The world's first stored-program
electronic digital computer that used
the Williams Tube as its memory

1946
John Presper Eckert & John W.
Mauchly
ENIAC 1 Computer
In one second, the ENIAC (could
perform 5,000 additions, 357
multiplications or 38 divisions

Massachusetts Institute of Technology
(MIT)
Whirlwind
The US Navy asked MIT to build a
flight simulator. Whirlwind was an
analog computer at first but was changed
to a digital one due to its inaccuracy

1944

A room-sized, relay-based calculator

1949

1950

1951

Maurice Wilkes
EDSAC

Engineering Research Associates of
Minneapolis
ERA 1101
The first commercially produced
computer that held 1 million bits on its
magnetic drum, the earliest magnetic
storage devices

John Presper Eckert & John W.
Mauchly
UNIVAC Computer

of America, and General Electric
ERMA and MICR

The first mass-produced computer.
Spinning at 12,500 rpm, the 650´s
magnetic data-storage drum allowed
much faster access to stored material
than drum memory machines.
