Terminals are a bit more complex than they look. They’re a combination of central terminals and all the different interfaces with other operating systems. There are many different types of terminals and a lot of different types of operating systems. They need software to cover all cases when they’re working together, and that’s where terminal emulators come in.
For example:
- A Windows terminal emulator is the interface between a Windows operating system and the terminal. It translates Windows into the terminal’s code and behaves like a terminal on the user end, hence the word “emulator”.
- A 3270 emulation is the process of interfacing with an IBM 3270 terminal, one of the standard commercial terminal systems.
It’s pretty straightforward, but if you’re talking about terminal emulators, you need to know what systems are need to work with which terminals.
Generally speaking the names will tell you at least part of the story:
- The name of an operating system means the type of terminal emulator
- The name of a terminal tells you which type of emulation is required.
Just keep that in mind and you’ll be able to follow the logic!
