- Neolithic (Wikipedia)
The Neolithic or New Stone Age (from Greek νέος néos ’new’ and λίθος líthos ‘stone’) is an archaeological period, the final division of the Stone Age in Europe, Asia and Africa. It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This “Neolithic package” included the introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of settlement. The term ‘Neolithic’ was coined by Sir John Lubbock in 1865 as a refinement of the three-age system.

IBM PC DOS (an acronym for IBM Personal Computer Disk Operating System), also known as PC DOS or IBM DOS, is a discontinued disk operating system for the IBM Personal Computer, its successors, and IBM PC compatibles. It was manufactured and sold by IBM from the early 1980s into the 2000s. Developed by Microsoft, it was also sold by that company as MS-DOS. Both operating systems were identical or almost identical until 1993, when IBM began selling PC DOS 6.1 with new features. The collective shorthand for PC DOS and MS-DOS was DOS, which is also the generic term for disk operating system, and is shared with dozens of disk operating systems called DOS.
