Organizations often had only very few computers in relation to the number of users, so they needed these cheap dumb terminals to allow multiple users to access the few more powerful computers.īecause of newer manufacturing methods, computers and monitor technology became more powerful and cheaper to make, leading to the the dumb terminal becoming obsolete both in function and concept. Most dumb terminals were made to run with the FreeBSD operating system and were in wide use in the 1970s up to the early 1980s because of the relatively large costs of computers. Instead, the dumb terminal sends the user inputs to a computer that runs the needed programs which then sends the results to the terminal for display. No programs can be run on these devices at all. Dumb terminals are called such because they had very little processing power, as they simply process a limited number of display commands.
