In 1974, Intel introduced 8080, First 8-bit CPU, which needed OS, Intel asked Gary Kildall, to write one. Kildall built a controller for 8-inch floppy disk and linked with 8080, then wrote a disk-based operating system called CP/M (Control Program for Microcomputers) Kildall then formed a company, named Digital Research, to further develop and sell CP/M.

Features of 4th Generation computers In 1977, Digital Research rewrote CP/M also for Zilog Z80, and other CPU chips and dominated the world of micro computing for about 5 years. Early 1980s, IBM introduced PC and asked Bill Gates to license his BASIC interpreter and an OS to run on the PC, Gates proposed Digital Research’s CP/M but Kildall did not cash the opportunity. IBM again asked Bill Gates for an OS, who formed Microsoft and bought DOS (Disk Operating System) from a local manufacturer, renamed it as MS-DOS (MicroSoft DOS) and Licensed to IBM PC.

Features of 4th Generation computers MS-DOS used on 80386 and 80486, Initial version was primitive but later had adv. features taken from UNIX. CP/M, MS-DOS, and other OS were commands based. In the 1960s, Stanford Research Institute invented GUI. Steve Jobs, co-inventor of Apple, first introduced GUI based expensive Lisa, which failed commercially. He then introduced a cheaper and user friendly Apple Macintosh, which had a huge success. .
