TYPES OF MICROPROCESSORS

In last many years, there have been remarkable improvements in the technologies of processors.

Initially the Microprocessors for PCs were 8 bits; that is processors were able to process and transfer 8 bits of data together.

Then there were successive releases of 16 bits, 32 bits and 64 bits processors.

Present day’s processors are able to process 64 bits of data simultaneously.

The microprocessors of PCs have improved remarkable in terms of processing speed and memory capacity. etc;
