The pick-up pattern of a microphone is the sensitivity to sound relative to the direction or angle from which the sound arrives, or how well the microphone "picks up" the sound from different directions. The most common types are: Cardioid, Omnidirectional, Unidirectional, Bidirectional.

CARDIOID
The most commonly used pattern is most sensitive at 0° (the front) and least sensitive at 180° (the back). This isolates it from unwanted ambient sound. You can use this for most recording applications. It is easy to get a good signal as the cardioid pattern blends out a bad sounding room, a noisy fan in the background, etc.

OMNIDIRECTIONAL
The omnidirectional microphone has equal sensitivity at all angles. This means it picks up sound evenly from all directions. Therefore, the microphone need not be aimed in a certain direction. It will be especially useful in good sounding rooms.

UNIDIRECTIONAL
Unidirectional microphones are most sensitive to sound arriving from directly in front (at 0°) and less sensitive in other directions. This makes unidirectional microphones effective at isolating the desired sound from both unwanted sound and ambient noise.

BIDIRECTIONAL
A bidirectional microphone (with figure-8 pattern) picks up the sound from in front of the microphone (at 0°) and from the rear (at 180°), but not the side (at 90° and 270°). It can be beneficial in situations where you do not want a signal coming from a 90° angle to bleed into the microphone.
