DATA ORGANIZATION IN DOS
DOS divides the secondary storage of computer into logical areas knowns as drives.Each drive is recognized by a letter followed by colon.For example ,the first floppy drive is called A: drive and second floppy drive is called B: drive. The hard disk may be assigned the letter c and called c: drive and CD drive may be called D: drive.
The capacity of hard is commonly very large.It is normally divided int logical parts called partitions.The FDISK utility is used to divide the hard disk into partitions .Each partition is aslo assigned a drive letter.If the hard disk is divided in four partitions ,these partitions are called C:,D:,E: etc
The data on drives is organized in the form of directories and files.A logical division of a drive where files are stored is known as directory.A drive may have many directories .DOS creates a directory on the disk automaticlly when the disk is formatted .This directory is called root directory.A directory within a directory is called subdirectory.
The directory in which the user is currently working is called as present working directory.
DOS interprets all commands with reference to the present working directory until the user specifies any other directory.
