Refers to the base-8 number system, which uses just eight unique symbols (0, 1, 2, 3, 4, 5, 6, and 7). Programs often display data in octal format because it is relatively easy for humans to read and can easily be translated into binary format, which is the most important format for computers. By contrast, decimal format is the easiest format for humans to read because it is the one we use in everyday life, but translating between decimal and binary formats is relatively difficult.
In octal format, each digit represents three binary digits, as shown:
With this table it is easy to translate between octal and binary. For example, the octal number 3456 is 011 100 101 110 in binary.
- odd header
In word processing, a header that appears only on odd-numbered pages.
An octet is 8 bits. It is equivalent to a byte, as long as the byte is also 8 bits. Bytes range from 4 – 10 bits, but octets are always 8 bits.
- odd parity
The mode of parity checking in which each 9-bit combination of a data byte plus a parity bit contains an odd number of set bits.
- off-page optimization
In search engine optimization, off-page optimization refers to factors that have an effect on your Web site or Web page listing in natural search results. These factors are off-site in that they are not controlled by you or the coding on your page. Examples of off-page optimization include things such as link popularity and page […]
