CPU

all about it!

Central Processing Unit

it's the hardware in the computer that has all the 'instructions' of the computer program. The term CPU has been used for as long as since the 1960s. The design of the CPU's has changed over the years but their fundamental operation has stayed the same.
Computers such as the ENIAC had to be physically rewired to perform different tasks, which caused these machines to be called "fixed-program computers." The idea of a stored-program computer was already present in the design of J.Presper Ereckt and John WilliamMauchley's ENIAC, but was initially omitted so that it could be finished sooner.On June 30, 1945, before ENIAC was made, mathematician John Van Neumann distributed the paper entitled First Draft of a Report on the EDVAC. It was the outline of a stored-program computer that would eventually be completed in August 1949. edvac was one of the fiurst stored computers, that helped store the CPU.

Facts

  • Intel came out with the first CPU
  • The original CPU chip was skipped over for the original emergency
  • Different CPU chips handle different data differently, eg, the mac is different to the pc, how they get used, different links to go to different places, therefore, the CPU chip is different.
  • 8088 and 8086 are an example of two different CPU's
  • 8088 and 8086 are supposed to be 30% faster than the first made Intel CPU's
  • CPU's are useful for technical, market and professional knowledge
  • Not all central processing units have pins on their bottom sides (if they do, take care, because they are quite delicate and easy to bend).
  • CPU's can get quite hot, even if they are on for a short period of time
  • CPU's are actually part of a computer, it's on the inside of every one
  • To cool down a CPU when it is working, you can get a heat sink, and they are designed to lower the temperature by dissipating heat into the surrounding air
