File Systems and Disk Management

The three kinds of files in a file structure are byte sequence, record sequence, and tree.

Sequential access involves reading all bytes/records from the beginning, whereas random access allows reading bytes/records in any order.

An executable file is a file that contains machine code that can be executed directly by the computer.
