In the 1970s and early 1980s, a number of companies manufactured dumb terminals. The most common were DEC, Wyse, Televideo, IBM 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.
