The correct answer is: join two similar pipes

Explanation:

In the context of plumbing and piping, a socket is a type of fitting used to join together two ends of a pipe. When the two pipes to be joined are similar in terms of their type and size, a socket can be used.

The purpose of a socket is essentially to ensure a secure connection between two sections of pipe, enabling the fluid to flow smoothly from one to another without leaking.

Option 2) "divert direction of pipe": This is typically the function of elbow fittings, which change the direction of the pipe run.

Option 3) "Keep the pipe in the same direction": While sockets can be used in straight runs of pipe (keeping the pipe in the same direction), this isn't their defining function.

Option 4) "join two dissimilar pipes": While it's possible for certain types of fitting to join two pipes of different sizes or materials, typically a special type of fitting called a reducer or adaptor would be used for this task, not a socket. Sockets are most commonly used to connect two similar pipes.
