In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:
1.8×10 1: ENIAC, first programmable electronic digital computer, 1945 [2] 5×10 1: upper end of serialized human perception computation (light bulbs do not flicker to the human observer) 7×10 1: Whirlwind I 1951 vacuum tube computer and IBM 1620 1959 transistorized scientific minicomputer [2]
Although the Ballistic Research Laboratory was the sponsor of ENIAC, one year into this three-year project John von Neumann, a mathematician working on the hydrogen bomb at Los Alamos National Laboratory, became aware of the ENIAC. [61] In December 1945, the ENIAC was used to calculate thermonuclear reactions using equations. The data was used ...
Step #3: Add more RAM to your hardware. RAM is a temporary memory used by your computer's operating system and helps your programs run smoothly.
The gap between processor speed and main memory speed has grown exponentially. Until 2001–05, CPU speed, as measured by clock frequency, grew annually by 55%, whereas memory speed only grew by 7%. [1] This problem is known as the memory wall. The motivation for a cache and its hierarchy is to bridge this speed gap and overcome the memory wall.
