Home > Dumb terminal
A dumb terminal in computing consists of a computer screen and keyboard, but practically no processing ability. They allow a user to carry out work on a remote server, minicomputer or mainframe. They have largely been superseded by personal computers.Dumb terminals, sometimes dubbed glass teletypes, display text on a screen, usually in monochrome, and allow the user to send commands to the server computer to input or display data, or to perform some action. They include limited processing power to enable them to issue simple commands ('escape sequences') for clearing the screen and positioning the cursor. Some later terminals included a limited graphic display capability.
In the 1970s and early 1980s, a number of companies manufactured dumb terminals. The most common were DEC, Wyse, Televideo , IBM, Lear-Siegler and Heath.
Today, most telnet clients provide emulation of the most common dumb terminal -- the DEC VT100.
Smart terminals provide additional resources to perform local editing and simple processing. Basically, such smart terminals (often referred to as network computers or simply NCs) are low-cost PC platforms with no external storage like hard disks or CD-ROMThe CD-ROM (an abbreviation for " Compact Disc Read-Only Memory" ( ROM) ) is a non-volatile optical data storage medium using the same physical format as audio compact discs, readable by a computer with a CD-ROM drive. A CD-ROM is a flat, plastic disc wit drives booting from a server in the network.
