The record access method is dependent on the physical medium on which the file is stored. Magnetic tape is sequential by it's extremely nature to read a record you must start at the beginning of the tape and sequentially read every record until you get to the one you want. With disks, obviously random access is possible. It is the same as the difference between audio compact disc and audio cassette. With audio tape you have to begin at the beginning and run the tape forward until you get to the song you want to hear. With compact disc you are able to play the songs in random order or go directly to the track you want to hear.

You must use fork and pipe to complete this project. This project creates processes to add all numbers in a file. The user will enter a number (1, 2, or 4) of parallel processes
Another solution then would be to keep a pool of threads. Whenever a new task arrives, the system would simply get a thread from pool and set that thread to work on the given task.
What do you mean by best fit? Best fit allocates the smallest hole that is big sufficient. The entire list has to be searched, until it is sorted by size. This strategy creates
