  2. Octal - Wikipedia

    en.wikipedia.org/wiki/Octal

    Octal ( base 8) is a numeral system with eight as the base . In the decimal system, each place is a power of ten. For example: In the octal system, each place is a power of eight. For example: By performing the calculation above in the familiar decimal system, we see why 112 in octal is equal to in decimal.

    A binary clock might use LEDs to express binary values. In this clock, each column of LEDs shows a binary-coded decimal numeral of the traditional sexagesimal time.. The common names are derived somewhat arbitrarily from a mix of Latin and Greek, in some cases including roots from both languages within a single name. [26]

    A "56k" modem can encode or decode up to 56 000 bits per second. Decimal SI prefixes are also generally used for processor-memory data transfer speeds. A PCI-X bus with 66 MHz clock and 64 bits wide can transfer 66 000 000 64-bit words per second, or 4 224 000 000 bit/s = 528 000 000 B/s , which is usually quoted as 528 MB/s .
