What was the IBM personal computer used for?
The new IBM PC could not only process information faster than those earlier machines but it could hook up to the home TV set, play games, process text and harbor more words than a fat cookbook. The $1,565 price bought a system unit, a keyboard and a color/graphics capability.
Are all computers IBM compatible?
It originated in the early 1980s, when personal computers were manufactured with a specific BIOS that was reverse-engineered for compatibility with the IBM PC. Today, the majority of computers manufactured and used are either PC (IBM compatible) or Apple Macintosh compatible.

What is the difference between IBM PC and IBM compatible?
The computers designed as well as developed by IBM Corporation are called IBM PC. The computers which are designed by IBM but manufactured by companies other then IBM are called IBM Compatibles. It is also known as original or branded IBM.
What are the main two parts of computer?
Every computer is composed of two basic components: hardware and software.
- hardware includes the Physical features, which are every part that you can either see or touch, for example: monitor, case, keyboard, mouse, and printer.
- The part which activates the physical components cs alled software.
Which was the most popular operating system chosen for IBM PC?
Microsoft Windows
Descendants of the x86 IBM PC compatibles, namely 64-bit computers based on “x86-64/AMD64” chips comprise the majority of desktop computers on the market as of 2021, with the dominant operating system being Microsoft Windows.
Can the IBM PGC be used in the original IBM PC?
The PGC could not be used in the original IBM PC without modification due to the different spacing of its slots. In addition to its native 640 x 480 mode, the PGC optionally supported the documented text and graphics modes of the Color Graphics Adapter, which could be enabled using an onboard jumper.
Is the Professional Graphics Controller (PGC) supported in BIOS?
Introduced in 1984, the Professional Graphics Controller offered a maximum resolution of 640×480 with 256 colors at a refresh rate of 60 hertz—a higher resolution and color depth than CGA and EGA supported. This mode is not BIOS-supported.
Does the PGC support CGA (Color Graphics Adapter)?
In addition to its native 640 x 480 mode, the PGC optionally supported the documented text and graphics modes of the Color Graphics Adapter, which could be enabled using an onboard jumper. However, it was only partly register-compatible with CGA.
Is the IBM 5175 compatible with a VGA video card?
The PGC’s matching display was the IBM 5175, an analog RGB monitor that is unique to it and not compatible with any other video card without modification. With hardware modification, the 5175 can be used with VGA, Macintosh, and various other analog RGB video sources.
