What is a computer?
Computers are programmable machines that do things for us
what is the first computing device
the abacus (veryyy old) BUT ONLY FOCUS on this
new( 17 CENTURY WE GO SLIDE RULE)
Jacquard Loom
made punch cards to define complex patterns into textiles
punched cards by loom
a piece of stiff paper with holes, where presence or absence of holes in pre-defined positions to
dictate the design of cloth.
later (this technology became used in old laptops (before keyboards)
algorthims
a finite set of unambiguous instructions to solve a problem
its basically the recipe (deterministic steps to solve a problem )
, some examples from before khawrizimi
(greatest common divisor(300)bc and prime numbers (100 AD)
George Boole
created boolean algebra
its the logical foundation of digital computing circulatory
invention up to 1900
george boole, loom (puncjhed cards), algorthims, abacus
calude shannon (after 1900s) hundred years after georgoe boole
Introduced the application of Boolean Logic in creating digital computing machines
published "A mathematical theory of communication" which establishes the principles for
encoding information so it might be reliably transmitted electronically
Alan turing
English mathematician who conceived of the Turing machine(electro mechanichal) and broke
German codes(enigma machine) during World War II (1912-1954)
