Any data is stored internally in the computer as binary digits, but those are "bulky" - you need 4 binary digits for every hexadecimal digit, so hexadecimal is really a kind of shortcut to write out binary numbers.
Decimal is another option, but conversion between binary and decimal is more cumbersome than with hexadecimal. Therefore, for the new IP addresses (IP version 6), they decided to write them down in hexadecimal, instead of the decimal that is used for IPv4.
MAC (Medium Access Control) addresses, part of the 802 family of IEEE standards, have 48 bits. They are typically represented as six pairs of hexadecimal digits, eg: 00-11-22-DD-EE-FF (each digit is comprised of the hexadecimal digits 0-9 and A-F, from 0 to 15 decimal). Each hexadecimal digit is 4 bits in length, so the pair is 8 bits. Thus, the pair of numbers can represent decimal values from 0 to 255. In some notations, the "-" is replaced with ":", eg 00:11:22:DD:EE:FF. The pair of digits can also be referred to as an octet or a byte.
This is called an orderd pair. It is written as (x,y).
ordered pair
The pair of numbers are called "coordinates".
This is called an ordered number pair
The pair of numbers are called the coordinates.
This question feels incomplete, but as written the LCM is 2.
Any pair of numbers, whole or fractional (or even irrational) are proportional.Any pair of numbers, whole or fractional (or even irrational) are proportional.Any pair of numbers, whole or fractional (or even irrational) are proportional.Any pair of numbers, whole or fractional (or even irrational) are proportional.
Numbers with more than one factor pair are composite numbers.
That happens when one of the numbers is a factor of the other.
