Space Shuttle components include the Orbiter Vehicle with three clustered Rocketdyne RS-25 main engines, a pair of recoverable solid rocket boosters, and the expendable external tank containing liquid hydrogen and liquid oxygen.

The Space Shuttle was launched vertically, like a conventional rocket, with the two SRBs operating in parallel with the orbiter’s three main engines, which were fueled from the ET. Watch the video from Jared Owen for more info:
The SRBs were jettisoned before the vehicle reached orbit, and the ET was jettisoned just before orbit insertion, which used the orbiter’s two Orbital Maneuvering System (OMS) engines. At the conclusion of the mission, the orbiter fired its OMS to deorbit and reenter the atmosphere.

After the Space Shuttle arrives at one of the two launchpads, it would connect to the Fixed and Rotation Service Structures, which provided servicing capabilities, payload insertion, and crew transportation.The Space Shuttle’s operations were supported by vehicles and infrastructure that facilitated its transportation, construction, and crew access. The crawler-transporters carried the MLP and the Space Shuttle from the VAB to the launch site./wikipedia
