IBM-PC compatible computers one calls computers, which after a processor RESET the processor Intel 8086 copy (see: x86-Prozessor) and (x86-kompatibles) a BIOS starts.

IBM-PC compatible computers are called PC briefly, as platform in demarcation opposite Apple Macintosh models and others. Since the term personnel computer was used however also for other architectures, this designation is not always clear.

History

First home computers came with a ROM, which the operating system contained. Thus an update was possible only by exchange this (at that time of expensive) component. Also were not always available Rome with sufficient storage capacity. Therefore one turned into to deliver the computers with a firmware which loads the operating system from an external storage medium.

Since the IBM-PC - contrary to its products of competition at that time - was developed with commercial components exclusive, this led to numerous Nachbauten.Der IBM-PC developed to an unofficial industry standard, because he could be copied without Lizenzierung of IBM.

During the introduction of new processors with 32-Bit word width integrated the chip manufacturer Intel 8086 on the chip, so that further x86-kompatible computers could be built. In order to keep the current consumption of today's chips as small as possible, the is emulated today through in the processor integrated firmware.

Interfaces

So that the computers of available operating systems on different hardware, compatible for IBM-PC, run, it requires the development except the x86-kompatiblen processor also more uniformly interface these however in the run was modernized.

See in addition:

• Peripheral Component Interconnect (PCI)
• PCI express
• PS/2-Schnittstelle (become outdated)
• Universal Serial bus
• ATA/ATAPI
• Industry standard Architecture (become outdated)
• VESA local bus (become outdated)
• PCMCIA
• Parallel haven (become outdated)
• FireWire
• OATHS
• VGA (connection)
• Serial ATA
• Serial interface (become outdated)

These interfaces are partly used also by other hardware. A use of attached extensions presupposes possibly however the availability of appropriate drivers.

Operating systems

For IBM-PC compatible computers are available nearly all operating systems. Are common:

• DOS
• Linux
• Microsoft Windows
• OS/2
• different Unix derivatives
• ZETA (advancement of BeOS)

• IA-32
• x86-64

• RK format
