What will be an ideal response?
A terminal is the channel that allows a certain user to log in to a Linux kernel, and there can be many terminals in Linux that allow you to log in to the computer locally or across a network. After a user logs in to a terminal, she receives a user interface called a shell, which then accepts input from the user and passes this input to the kernel for processing. Since Linux is a multiuser and multitasking operating system, thousands of terminals can be used. Each terminal can represent a separate logged-in user that has its own shell.
