What is a 286 computer?
The Intel 80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bit microprocessor that was introduced on February 1, 1982. It was the first 8086-based CPU with separate, non-multiplexed address and data buses and also the first with memory management and wide protection abilities.

What year did the 386 computer come out?
Alternatively referred to as a 386 or the i386, the 80386 is a CPU developed by Intel. It was introduced in October 1985 as an upgrade to the 80286 processor, and stopped being produced in September 2007.
How fast is 286?
The first 286 pedaled along at 6MHz and, like the original 8086, would later double in speed. However, clock for clock, the 286 boasted twice (or more) the performance of the 8086, a generational leap in the x86 architecture that has never been duplicated to this day.
What ISA 486 computer?
The fourth generation of the Intel x86 family of CPU chips. The term may refer to the chip or to a PC that used it. Introduced in 1989, it was the successor to the 386 and the first chip in the line to include a built-in math coprocessor. Providing acceptable performance for DOS, it was bare minimum for Windows.
What are the CPU contents used in 80286?
The additional fields available in 80286 flag registers are:
- IOPL – I/O Privilege Field (bits D12 and D13)
- NT – Nested Task flag (bit D14)
- PE – Protection Enable (bit D16)
- MP – Monitor Processor Extension (bit D17)
- EM – Processor Extension Emulator (bit D18)
- TS – Task Switch (bit D19)
What year did 486 come out?
The Compaq Portable 486 is a computer released by Compaq Computer Corporation in 1991.
Which flag is used to hold privilege level?
Explanation: The IOPL flag bits indicate the privilege level of current IO operations.

What is the name of the first 16 bit microprocessor?
Intel 80286. The Intel 80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bit microprocessor that was introduced on February 1, 1982. It was the first 8086 based CPU with separate, non- multiplexed address and data buses and also the first with memory management and wide protection abilities.
What kind of RAM does the IBM 286 have?
The 24-bit address bus of the 286 expands RAM capacity to 16 MB . PC DOS 3.0 was included with support for the new AT features, including preliminary kernel support for networking (which was fully supported in a later version 3.x release) The motherboard includes a battery backed real-time clock (RTC) using the Motorola MC146818.
