When did the 386 processor come out?
1985
The Intel 386, originally released as 80386 and later renamed i386, is a 32-bit microprocessor introduced in 1985. The first versions had 275,000 transistors and were the CPU of many workstations and high-end personal computers of the time.
What is the difference between SX and DX in a 386 chip?
The 80386DX Intel processor has a 32-bit external bus and a 32-bit address bus. Memory access is faster with the DX Intel processor. The SX takes two fetches to get a piece of memory, whereas the DX takes only one fetch. Also, the SX is limited to 16MB of addressable memory, while the DX may have as much as 4GB.
What is a 386 computer?
The PC-386 was a 32-bit personal computer with a 20-MHz 80386 CPU that could run PC-98 series software at more than twice the speed of 16-bit machines. Featuring ample extensibility, the PC-386 offered high-speed processing of business applications along with excellent cost effectiveness.
What is DX 80386DX?

How fast was a 386 computer?
4 million operations per second
Compaq introduces the Deskpro 386 system At 4 million operations per second and 4 kilobytes of memory, the 80386 gave PCs as much speed and power as older mainframes and minicomputers.
What was the first 32-bit computer?
The world’s first single-chip fully-32-bit microprocessor, with 32-bit data paths, 32-bit buses, and 32-bit addresses, was the AT Bell Labs BELLMAC-32A, with first samples in 1980, and general production in 1982.

4 kilobytes
What is 32-bit browser?
32 Bit Software Browsers, like all software these days, for the most part come in one flavor – 32 bit. (This is changing, though.) That means no matter how much RAM you have installed, the software can’t take advantage of it. A 32-bit program is limited to 4GB of RAM.
