An andriod is a man made being of sorts. More information can be found in the Race List.

Star Trek is still playing around with this technology, and while it is available, it is only equipped on ships when requested. A beta version is currently equipped on the Enterprise.

A comminicator is a small device (it looks like a cellphone without buttons, but it does not require being held up to your ear to hear) used for communicating. Every crew member is required to have a communicator at all times, and there are several communicator stations attached to a ship's walls as well.

Everyone knows what a computer is, but this one basically runs the ship. It is also a digital library. Anything from the ship can be downloaded onto a PADD or transported to another computer using a card (that looks like a floppy disk, but is colorful and way more cool). The library can also be accessed using any computer on the ship. Some materials may be classified and require a security code to access – so not everyon can actually read some things.

This is a hard crystalline mineral that can be made, but is naturally occuring on some planets. It is used for energy, such as powering starships and in some places instead of electricity.

It seems silly that a door is a technology. But most doors now open with a sliding motion, and without having to physically open them. They are controlled by a button on either side of the room (and they make a cool WHOOSH sound!).

Holodecks are not yet known to the Federation. They will be introduced to the Enterprise by the Xyrillians (when that time comes, the Enterprise will be the first Federation ship with Holodeck technology). A Holodeck is a room equipped with holoemmitters that allow the room to simulate something. They currently are not capable of creating a simulation of a human, but can be used to create landscapes and towns. Holodecks have the option of turning a safety (what allows people to be hurt of not) on or off. They are also able to be “written” by people so they can create or recreate places they want to go.

These engines are used when traveling under the speed of light.

A PADD is a small device used to record information. It is often used for report writing.

Replicators
Replicators are another technology in their testing period. The Enterprise is the first Federation ship to be equipped with replicators. They are basically a square indent in the wall. You tell it what you want, it could be a food, drink, or object, and it will give it to you. Replicators work on energy, and are notorious for giving people the wrong thing, or not exactly what they asked for.

Transportation is commonly used just about everywhere. It is used to transport someone from one place to the other by breaking down their atoms and rematerializing them somewhere else. Transporters are not perfect, and have been known to cause problems. They are also only able to work within a reasonable distance (unless you talk to Scotty, of course).

A tricorder is primarily a science or a medical instrument, and is used to anaylyze something – plant, body, planet, etc. They range from very large very small.

This is what allows ships to travel the speed of light. It is used when someone wants to get somewhere fast (um, yeah?) and has different speeds within itself. Currently the highest Warp for the Enterprise is 6.9.

A universal translator that translates anyone else's language into the one you speak, making it possible to communicate with any race. These are used by the Communications Teams and can become obsolete when there is a person on board that has studied various languages.

Wormholes are actually not a technology specifically, and are found naturally in space. They take someone through either space or time, or sometimes both, within a fairly short period of time.
