Chapter 3 Operating Systems Concepts 1 A Computer Model An operating system has to deal with the fact that a computer is made up of a CPU, random access memory (RAM), input/output (I/O) devices, and long-term storage. File Organization. The database is stored as a collection of . files. . Each file is a sequence of . records. . A record is a sequence of fields.. One approach. Assume record size is fixed. Each file has records of one particular type only. 1:. Introduction . to Computer. 1. Computer.
