Historical development of the personal computer (PC)
personal computer history associated with development phases of IBM-PC. IBM-PC machine is starting from a laboratory in Atlanta (Georrgia, USA), the purpose of the experiment is to design a low end computer products. This means that IBM no use of genuine processor that uses cheaper processors from other manufacturers such as Intel, Motorola, Zilog.
1979-1980: IBM launched Datamaster machine processors use 16 bit Intel 8086.
1980: The concept: Personal Computer (PC). The IBM-PC first using 8bit microprocessor of Intel 8085.

The IBM-PC first using 8bit microprocessor of Intel 8085.
1981-1982: Though Intel 16bit processor but high price, to satisfy the market for inexpensive, Intel launched the 8-bit 8088 processor, but in it is IC 8086. IBM used 16bit processor to design the second generation PC: PC-XT (extended technology) 8088 with 8 bit data bus and 20bit address bus, capable of managing up to 1 MB of physical memory, running at clock frequencies 4, 77 MHz. Inside it has eight expansion slots (slots 8bit XT - or XT-Slots), this slot has 62 pins. PC-XT equipped two 360KB floppy disks, 256 KB RAM (plug in slot 1 in 8 over). PC-XT operating system CP / M and 80 of Microsoft BASIC program.
1984: When 16bit processors are familiar market, given Intel 80286 processor, 16bit processor is perfect, further 4bit address bus, 16MB of memory management. IBM launched the PC-AT (advanced technllogy) with 80286 processor, with its PC operating in protected mode that allows sharing of memory long passages flexibility and priority to the application program thereby avoiding collisions when multiple programs running at once - this is the foundation of multitasking on the PC-AT 80286 Working with 6-8 MHz frequency, due to additional 8bit data bus, local bus 4bit only, 8bit interrupt request bit hard and some new controls, so PC-AT need additional slots.
1987: Generation nascent PC with processor 80386. Start here publicly IBM machine structure and content of the program operating systems on the basis (BIOS), which helps other companies can produce compatible computers and circuit boards that plug compatible IBM-PC structures become an industry standard architecture. This makes the design enclosed PS / 2 (simultaneously) failed on the personal computer market in the IBM-PC architecture increasingly dominate the personal computer market. 80386DX Processor is a complete 32-bit processor with 32-bit data bus, 32-bit address bus with a maximum of 4GB of memory. To meet the speed of 80386 and high yc of the control circuit high-resolution screen, the standard slot EISA (Extended Industry Standard Architecture) was launched. This is the standard 32 bit slot with transfer rate is 33Mbit / s.
1990: 80486 born with more functions, namely 8 Kbyte cache code (code cache) and a math co-processor. Working frequency characteristics of computers during this period is 66 MHz.
1993: The first Pentium microprocessor advent ushered in a new era with 64bit data bus, 32-bit address bus, 8KB data cache, 8KB buffer code. Math coprocessor of Pentium work 10 times faster than 80486. When this the major hardware manufacturers agreed a new standard PCI-bus slot (Peripheral Components Interconnect), and therefore the main circuit machine personal computer only a few chips, all the peripheral circuits of IBM-PC architecture and PCI controller chips are integrated into a single chip, called a PCI-chipset.
1995: Ability to multi-environment (multimedia) of personal computers increasingly perfecting the Pentium MMX, Pentium Pro, Pentium II one came. The highest clock frequency of 300 MHz. A new peripheral interface standard was born from an agreement from many large firms are diversified serial bus USB (Universal Serial Bus).
1999 P !!! Birth, PC99 abolish the ISA bus standard. PCI Bus, advanced graphical interface AGP, USB peripheral interface and IEEE 1934 are features.
From 2000: A 64-bit processor architecture was born. Intel launched more appropriate synthesis IC with genuine processor. Chipset responsible for most of the control functions on the machine and display controller implanted inside. Personal computer market as well as market and IC processor sum is divided into sections to meet the diverse needs of society.
