Sekizli Sayı Sistemi / Octal Number System

The Octet Number System is another type of computer and digital enumeration system that uses the base-8 system.

Octet numbering is very similar in principle to the previous sixteen-numbering system, except that it is octet, a binary number is set to a binary number, divided into groups of only 3 bits, or (0) 000 with a separate value.

Octet numbers have only a range of "8" digits, (0, 1, 2, 3, 4, 5, 6, 7) Uses a base-8 numbering system and therefore equals q "8".

Then the main feature of an octet number system is that there are only 8 different counting digits from 0 to 7, and each digit has only a weight or value of 8, starting with the least meaningful bit (LSB).In the first uses of counter circuits, the octet numbers and octet numbering system were very popular for counting inputs and outputs, since they worked in octet counts, the inputs and outputs were eight numbers, one byte at a time.

Like the hexagon system, the "octet number system" provides a convenient way to convert large binary numbers into more compact and smaller groups.However, these days the octet numbering system is used less often than the more popular sixteen numbering system and has almost disappeared as a digital-based number system.

Because the octet number system uses only eight digits (0 to 7), no numbers or letters above 8 are used, but converting from decimal number to octet and binary to octet follows the same pattern we've seen for sixteen before.

To count above 7 in the octet, we need to add another column and start over, similar to the hexadecimal number. 0, 1, 2, 3, 4, 5, 6, 7, 10, 11, 12, 13, 14, 15, 16, 17, 20, 21….vb

Although it is another type of octet number system, it is used very little today, instead the more widely used Sixteen Number System is used because it is more flexible.
