- What is Crescat?
- Crescat is a terminal emulator for communicating with remote computers via the SSH protocol.
- What is a terminal emulator?
- A terminal is the simplest means of communication between a human and a computer: It's a keyboard for the human to type on, and a screen (or some paper) for the computer to respond. Terminals used to be specially-built machines for this purpose, but nowadays computer programs emulate the behavior of specific kinds of terminals.
- What terminal does Crescat emulate?
- Crescat emulates an "ANSI color" terminal, plus support for the ISO Latin-1 character set.
- What is SSH?
- SSH is a protocol used between computer processes -- Crescat and the computer it connects to in this instance -- for protecting the data that passes between them from being read or forged by others. Most system operators who offer terminal access to their systems offer SSH, and encourage its use.
