Q2) Why is the vi editor called a bimodal editor? Explain.
Answer: The vi editor is called a bimodal editor because it functions in one of two modes: command mode and insert mode.
The vi editor opens command mode, in which you must use the keyboard to perform functions, such as deleting text, copying text, saving changes to a file, and exiting the vi editor. To insert text into the document, you must enter insert mode. One method of entering insert mode is to type the i key on the keyboard while in command mode; the vi editor then displays --INSERT-- at the bottom of the screen and allows the user to enter text.
When in insert mode, you can use the keyboard to type text as required, but when finished you must press the Esc key to return to command mode to perform other functions via keys on the keyboard.
Q3) The file .file.dat is an example of a(n) ____________________ file.
