Size Interesting fact about each 1  Vacuum Tubes Invented in 1904 Old Technology like Old Radios As big as 2 fingers They turn on and off 2  Transistors 1926 It is used as a switch for many devices Small Transistors are usually made of silicon or germanium 3  Chips (Integrated Circuits) 1949 they are used in computerrs, they are found inside the motherboard. They are used as timers, microprocessors, memory and many other uses. Small Transistors are already built into the motherboard so you don't have to buy them. 4  Microprocessors Computers on  a chip 1971 they are used as the brain of the computer, they process information and organize them.  Fits in your hand Microprocessors can do alot of things from simple to complex. Like adding two numbers, or copying a series of letters and numbers.  5.  Networking Parallel Computing Fibre Optics Fibre Optics(1790) Parallel Computing (1969) A bunch of computers that work together to preform 1 or more tasks.  Fits in an entire room Parallel Computers are usually used by companies, and are not acessable or affordable to the public.
