Development of computers
Firstly, A computer is an electronic device/machine that receives, stores manipulates communicates information and can be programmed to perform specific tasks repeatedly.
Secondly, A typical block diagram shows Input, Output, C.P.U and Memory. Whereas, example of input are keyboard, mouse cursors. Outputs are monitor display, printer, speaker. Memory are data that can be replaced and can be taken out and either stored in. and lastly C.P.U stands for central processing unit. Some people say that it acts as the brain of a computer system, well its actually is the, centre core or should I say the heart beat of the computer.
Lastly, computer enhancements from time to time are improved, from desktops to notebooks/laptop. The price/performance decreases with time where as before it cost about $4000-$5000,Now it only cost for $900-$2000.This is due to the rate of increase in integration circuit from very large scale circuit component to very small circuit components.
