Answer :
The vi editor is a bimodal editor with two modes: Command Mode for executing editor commands and Insert Mode for editing text. Switching between modes is performed using specific keyboard commands.
The vi editor is called a bimodal editor because it operates primarily in two modes. These two modes are Command Mode and Insert Mode. In Command Mode, users can execute commands to manipulate text, save files, or exit the editor, amongst other functions. It is a non-editable mode where commands can be entered to perform specific operations. On the other hand, Insert Mode is used for editing text, which is similar to how one would normally type text in a word processing program. You can switch to Insert Mode from Command Mode by pressing keys like 'i' (insert), 'a' (append), or 'o' (open a new line), and return to Command Mode by pressing the 'Esc' (Escape) key.
