Abacus Often recognized as the first computing device, it uses beads
on a string or rod to temporarily store and manipulate
data. Developed in China, then later used by early Greek
and Roman civilizations.
The Leibniz Machine Also known as the "Step Reckoner", it was an early device
that used gears to perform basic arithmetic functions, such
as
adding and subtracting
The Analytical Engine A purely mechanical machine developed by Charles Babbage
which read instructions from punched paper cards. Often
recognized as the world's first programmable computer
Ada Lovelace Considered the world's first programmer; published a paper
demonstrating the programmability of the Analytical Engine
Where did the usage of punched paper In 1801 in the textile industry, originally used for programming
cards originate? looms
Herman Hollerith Designed a tabulating machine which used punched paper
cards to help speed up the tabulating process of the 1890 US
Census
Up until how recently were punched paper Until the 1970's
cards used in computing?
What type of switching component did the Electro-mechanical relays, as seen in the Bell Laboratories MK
earliest computers use? I, completed in 1944
What invention replaced electro-mechanical Vacuum tubes, as seen in the Atanasoff-Berry Machine and the
relays in early computing? Colossus
How did vacuum tubes change early Gave way to the first fully electronic computers. Tubes were
computing? smaller, faster, and more reliable than relays.
Colossus An early computing device used to decipher German
encrypted messages during WWII
, ENIAC Electronic Numerical Integrator and Computer; the world's
first general-purpose computer
Moore's Law The observation that computing power roughly doubles every
two years
