Microprocessors are classified into different types on the basis of the bit of operation. Based on bit of operation at a time, the following are the types of microprocessors:
==> 4 bit. e.g. Intel 4004
==> 8 bit. e.g. Intel 8088, Zilog Z80, Z180
==> 16 bit. e.g. Intel 8086, 80186, 80286, 80386
==> 32 bit. e.g. Intel Pentium, Celeron, AMD Sempron
==> 64 bit. e.g. AMD Athlon.
Based on the instruction set microprocessors are classified into:
==> RISC — Reduced Instruction Set Computing. These types of processors are commonly used in ovens, air conditioners, etc.
==> CISC — Complex Instruction Set Computing. The types of processors are used in desktops, laptops and servers.
