The Intel 80286 is a 16-bit microprocessor that was introduced in 1982. It was the successor to the Intel 8086, and was the first microprocessor to support the protected mode of operation which allows for the creation of multitasking operating systems.
The 80286 was used in a wide variety of personal computers and workstations, and was also used in a number of military and aerospace applications. It was eventually replaced by the Intel 386 in 1985.
What are the features of 80286?
The Intel 80286 was the successor to the 8086, and was released in 1982. It had a number of new features, including:
-A 16-bit data bus
-A 20-bit address bus
-A new instruction set
-A new, faster clock speed
-On-chip memory management unit
-Support for virtual 8086 mode
What type of motherboard is used by 80286 processors?
The 80286 was a 16-bit microprocessor with a 20-bit address bus, released in 1982. It was used in IBM PC/AT computers, and was the first chip in the x86 line to support protected mode. The protected mode allowed the 286 to address up to 16 MB of memory, a significant increase over the 1 MB limit of the earlier 8086 and 8088 processors. The 286 was also much faster than earlier x86 chips, thanks to its on-chip cache and higher clock speed. Earlier x86 chips required a separate memory controller chip to access the video RAM, but the 286 had this functionality built-in, further increasing its speed.
The 286 was available in both surface-mount and through-hole versions. The through-hole version was used in the original IBM PC/AT, while the surface-mount version was used in later models. The surface-mount version was also used in a number of non-IBM computers, such as the Compaq Portable and the HP 110.
The 286 was succeeded by the 386 in 1985.
What is main difference of 80286 and the 8086 processor?
The 8086 processor was released in 1978 as Intel's first 16-bit microprocessor. The 8086 was succeeded by the 80286 processor in 1982. The 286 was a significant step up from the 8086, offering a number of improvements including a larger address space (1 megabyte instead of 64 kilobytes), a larger number of general purpose registers (16 instead of 8), and a higher clock speed (6 MHz instead of 4.77 MHz). The 286 was also the first Intel processor to support virtualization.
The main difference between the 8086 and 286 is that the latter is a 16-bit processor while the former is an 8-bit processor. The 286 is also faster and has a larger address space. Who invented 80286? The 80286 was invented by Intel in 1982.
When did 486 computers come out?
The first 486 computers were released in 1989 by companies such as IBM and Compaq. These early 486 machines were expensive and not widely available. It was not until 1991 that the price of 486 computers began to drop, making them more affordable for the average consumer. By 1992, the 486 had become the standard computer for business and home users alike.
