On August 12, 1981, IBM joined the computer race when it introduced the IBM 5150 PC. It featured the 4.77-MHz Intel 8088 CPU, 16 kB base memory, and the Model F keyboard. Its retail price was $1,565.

The same month, Microsoft received a request from IBM to create a new operating system for the IBM PC. The result was MS-DOS 1.0, which was branded as PC-DOS when shipped with IBM PCs. PC-DOS and MS-DOS would eventually fork into separate products, and MS-DOS would mark the beginning of Microsoft's massive influence in the world of PC software.

Xerox Star workstation.

On April 27, 1981, Xerox introduced the Star workstation. The graphical user interface of the computer greatly influenced future Apple computers including the Lisa and Macintosh, and inspired many features of Microsoft Windows.

In September 1981, the Internet Engineering Task Force published RFC 791. The RFC document formally defined IPv4, the fundamental communications protocol used by most of the modern Internet.

Other computer events in 1981
