RANDOM ACCESS MEMORY(RAM)

RAM is the type of primary memory which is requires to run computer system. Once computer is turn on RAM is started to functioning data and programs from hard disk are loaded into RAM and from RAM. Processors process one by one. All this process is carried until RAM get power on while the power is switch off the data. Instructions are lost.Since, the access data are store in memory location in random manner. So it is called RAM. It is of two types:-

1) STATIC RAM:                                                                                                                                       It is type of RAM which is found in Pentium I, Pentium II and Pentium III computer. It has double notch and 1 to 168 numbers of pins for signal transmission.Since, it updates data and instruction store in after a long time. The process data and instruction are appeared in RAM for a long time. So, it is called Static RAM.

2)DYNAMIC RAM:-

It is found in Pentium IV computer which has one notch and 1 to 240 pins.it has high frequency rate than Static RAM. It is of two types:-                                                                                                        i)DDR1 RAM                                                                           ii)DDR2 RAM
