A computer desk is a service bureau providing computer services.
Computer bureaus developed during the early 1960s, following the development of time-sharing operating systems. These allowed the services of a single broad and expensive mainframe computer to be divided up and sold as a fungible commodity. And the development of telecommunications and the first modems encouraged by the growth of the computer office.
The computer office model shrank during the 1980s, especially the PC clone but also the minicomputer allowed services to be hosted on-premises .
