The maximum value in any number system is one less than the value of the base. The base in an octal number system is 8, therefore, the maximum value of the single digit is 7. It takes digits from 0 to 7.

The processor has some internal memory storage locations, known as registers. The registers stores data elements for processing without having to access memory.

The concentric circles are called as tracks. The tracks are numbered consecutively from outermost to innermost starting from zero. The number of tracks on a disk may be as few as 40 on small-capacity disks to several thousand on large capacity disks.

The reverse process is called decryption. It is the process of making the information readable again.

It is called as flowcharting. A flowchart is nothing but a pictorial representation of an algorithm.
