Local Machine Definition

The term local machine refers to the computer that a user is currently using on a computer network.

It can be considered to be the opposite of a remote machine, which is any host (i.e., computer connected to the network) other than the local machine.

A local machine has a default name of localhost, a default domain name of localdomain, and a default IP address of This is the so-called loopback address, because the information which is sent to it from a local machine is sent back to the same machine rather than being routed over the network to a remote machine.

Although the word machine is most commonly used to refer to a mechanical (or largely mechanical) device with moving parts, it is also frequently used in the computer field as a synonym for computer.
