What does restart mean?
Restart means to begin something again after it has stopped, failed, or been interrupted. The word is especially common in relation to computers, machines, vehicles, programs, conversations, negotiations, and economic activity. In technical settings, it often means returning a device or service to an operational state: a user might restart a computer, while an administrator restarts a server. It can also have a broader meaning of making a fresh attempt, as in restarting negotiations or a career. As a noun, a restart is the event or process of beginning again, or an attempt to resume after an interruption. The term is practical and broadly neutral, with no strong positive or negative connotation, although its frequent use in computing has made it especially familiar in modern usage.

Where does restart come from?
The verb is formed by combining the prefix re-, meaning “again,” with the verb start. The compound reflects a long-standing English pattern in which re- marks repetition, parallel to forms such as reopen and rewrite. The noun restart developed from the same compound and came into regular use as the language increasingly discussed interrupted and resumed processes.
