Computers consist of a CPU, Hardrive, RAM, and a cooling system which is responsible for passing data between it which makes the computer work
Computers have existed for a long time! Computers by technical definition are machines that can perform complex equations. These existed way before the modern computer,such as the abacus and Leibniz's Step Reckoner.
One of the most famous computer scientists, Alan Turning proposed the idea of a machine that could solve any complex equation. Known as turings machine, it became into reality with modern computers
Computer's consist of busses that are pathways towards which data or memory addresses are transferred. The path that the data goes is controlled through CPU Control Signals.
One of the most important pillars for computer science and computer history is boolean algebra. Developed by George Boole, it defines three operations "AND,NOT OR".These three operations would play a big role in the development of computers
Computers today consist of millions of transistors that are so small that it is comparable to a single blood cell.
