Dumb terminals

Dumb terminals were used in earlier days to connect to mainframe, which is located in a remote location. Dumb terminals is a power tools utility that do not have any processing capabilities as they do not have any microprocessor/CPU inside them. Due to this they will be very slow in processing user’s requests. They do not support many display features like color customization, Screen size customization, etc. They have poor edit features and angle drills, as they do not support the standard GUI features like cut, copy and paste. It does not allow any other application to run simultaneously as well.

Need for emulators

The increasing need to use a PC for non-programming purposes, such as word-processing, spreadsheet, communications etc. created the need to have a PC on the desk, next to the IBM Terminal. As this created a space crunch in the offices, a new class of IBM terminals came into existence. These “terminals” are PCs / workstations made to work like an IBM terminal. This is done by a process called Emulation. Here, each PC will run an emulator program. This program converts the PC data from ASCII to EBCDIC, and sends it to the mainframe. Upon receipt of data from the mainframe, the emulator converts it from EBCDIC to ASCII. These emulator programs are of the Terminate and Stay Resident (TSR) type. Emulators allow remote PCs and hand tools to communicate with IBM-Mainframe. Emulator session is another application like Word / Excel in your PC.
