All processing is performed on the server.
Usually has no hard disk, floppy disk drive, CD-ROM drive, or expansion slots. Runs with servers using Microsoft NT and Citrix WinFrame or the forthcoming Microsoft Windows Terminal Server for thin clients and Citrix pICAsso, using RDP or ICA protocol.

Hard disk, floppy disk drive, CD-ROM drive, and ISA slots are not required.
