First Fit

First Fit is a method used in computer memory management to allocate space for data or programs. When new data needs to be stored, the system scans through available memory segments, starting from the beginning, and selects the first segment large enough to hold the data. If that segment is too small, it moves on to the next, and so on, until it finds a suitable spot. This approach aims for quick allocation by stopping at the first suitable memory block, making it efficient but potentially leaving unused space scattered throughout memory.
