Final answer:
A static route is entered manually into a router by an administrator and does not change unless manually updated. It is used in situations where automatic updates are not necessary or desired.
Step-by-step explanation:
The type of route that is always entered into a router manually and does not change unless an administrator updates it is a static route. This type of routing implies that the network administrator must manually enter the IP address of the next hop or the exit interface directly into the router's configuration. Unlike dynamic routes that are created by routing protocols, static routes are not updated automatically and are often used for smaller networks or individual segments where there is a single path to the destination.
The manual configuration characteristic of static routes provides administrators with explicit control over the routing decisions, making them suitable for scenarios where simplicity and a predetermined route are advantageous.
