Intel 80286:

The Intel 80286 (frequently abbreviated to 286) is an x86-family 16-bit microprocessor that was introduced by Intel in the year of 1982. It can be utilized as a CPU for a multi-user microcomputer. It contains 134,000 transistors. The 80286's performance is more than twice that of its predecessors (the Intel 8086) per clock cycle. It contains two modes of operation: real address mode and virtual address mode. In real address mode 80286 is equivalent 8086, while, in virtual address mode, it has the facility of keeping each of the users program separately, protect system programs from destruction by the user's programs. It was extensively used in IBM PC compatible computers during the mid 1980s to early 1990s.
