ComputerCraft itself adds many different computers and turtle robots which can be programmed and used with Lua to perform various different tasks. Computers and turtles can both be extended with peripherals, which allows the computer to perform additional functions such as wired and wireless networking, printing, playing sounds, and more.
Turtles can also have tools applied which allow them to dig, mine, attack, hoe, and more. They are essentially one of the best tools for automating different in-world tasks.
For information on how to use the various APIs in the mod (as well as how to use the basics of the mod), you can check out the CC:Tweaked Documentation
