# Using a Terminal Emulator - PuTTy

### What is a Terminal Emulator

A terminal emulator is a computer program that replicates the functionalities of a physical computer terminal. With the help of a graphical user interface (GUI) or a command-line interface (CLI) users can interact with an operating system (OS). 

Terminal emulators are commonly used to access and control remote computers or network devices. They provide a way to enter commands, execute programs, and manage files on a computer system. Popular terminal emulators include programs like PuTTY, iTerm, and Terminal on macOS.
