Some Uses of Octal
The Octal number system is widely used in computing and computer programming. It became popular when systems such as UNIVAC 1050, PDP-8, ICL 1900, and IBM mainframes started using it for 6-bit, 12-bit, 24-bit, or 36-bit words. As each Octal digit represents 3 binary bits. It is also used in Unix-like operating systems where file permissions are often represented using octal numbers. Each digit corresponds to the settings for the owner, group, and others. For instance, 755 means read, write, and execute permissions for the owner, and read and execute permissions for others.
What is Octal ?
Octal is a number system with a base of 8 i.e. it uses 8 numeric values, namely, {0, 1, 2, 3, 4, 5, 6, 7}. This number system is mostly used in the programming of computer programs. For example (32150.7642)8, (275)8, (324)8, (2243)8 are Octal numbers. In this article, we will discuss the octal number system.
