Specifications of processor

•       Speed in HZ(hertz).

•       Width in bits ex: 64bit.

•       FSB Speed measures in HZ.

Cache leveles:-

       L1 a internal cache memory.

       L2 a external cache memory.

       L3 a mother board cache memory.

•       The CPU processes data at a very high speed.

•       Dynamic RAM can’t match the speed.

•       Hence, a special RAM is called cache is used.

•       Frequently access instruction and data will be store in cache. 

Cache memory 
K bytes /M bytes

1Khz= thousand cycles/sec

1Mhz=milion cycles/sec

1Ghz=bilion cycles/sec
