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. Later versions of the chip doubled and tripled internal speeds (see DX2 and DX4).
How much RAM does a 486 have?
It used an Intel 80486DX2 to support 210MB of hard disk and
up to 32MB of RAM
. Later, Compaq 486 desktop versions utilized similar technology to market its computers.
What came after 486?
Why brand name was important after the 486
It codenamed its 486 successor
the P5
, and when it released it, Intel gave it the brand name of Pentium. The name invoked the number five, but was completely trademarkable, unlike the number 586.
When did 386 computers come out?
The Intel 386, originally released as 80386 and later renamed i386, is a 32-bit microprocessor introduced in
1985
.
What was before the 286 computer?
| General information | History | Predecessor 8086, 8088 (while 80186 was contemporary) | Successor Intel 80386 |
|---|
Is 80386 still used?
As the original implementation of the 32-bit extension of the 80286 architecture, the 80386 instruction set, programming model, and binary encodings
are still the common denominator for all 32-bit x86 processors
, which is termed the i386-architecture, x86, or IA-32, depending on context.
How much RAM did a 386 have?
The Intel 386 came out in the late 1980s and was a 32-bit CPU with 32 address lines, allowing a maximum of
4GB of memory
, but many of the first PCs with this series CPU came with the stripped down 386SX, which had only 24 address lines for a maximum of 16MB of memory, but 386SX motherboards often allowed only up to 4MB …
What was the first ever computer?
The first mechanical computer,
The Babbage Difference Engine
, was designed by Charles Babbage in 1822. The ABC was the basis for the modern computer we all use today. The ABC weighed over 700 pounds and used vacuum tubes. It had a rotating drum, a little bigger than a paint can, that had small capacitors on it.

Did they have computers in 1986?
New computer products and services introduced in 1986
IBM introduced AIX
in 1986. CVS (Current Version Systems) was released in 1986 and became a venerable and influential revision control system. Compaq introduced the first 386-based PC compatible computer in 1986. MS-DOS 3.2 was released in April 1986.
How fast was a 386 computer?
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 were computers like in 1987?
Major computer events in 1987
IBM introduced the
PS/2 personal computer
with improved graphics, a 3.5-inch diskette drive, proprietary bus to help prevent clones, and a bidirectional 8-bit port. CompuServe introduced the GIF standard and images in 1987.
Is a microcontroller chip?
A microcontroller (MCU for microcontroller unit) is a
small computer on a single
metal-oxide-semiconductor (MOS) integrated circuit (IC) chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals.
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&T Bell Labs BELLMAC-32A
, with first samples in 1980, and general production in 1982.
What was the first 64 bit processor?
The first processor to implement Intel 64 was the
multi-socket processor Xeon code-named Nocona
in June 2004. In contrast, the initial Prescott chips (February 2004) did not enable this feature.
