How many bits are in a MAC Address and how is a MAC address commonly represented?

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.

How many bits comprise the network portion of a class c address?
Thirty bits make up the network portion of a class C address. Three bits are borrowed for the subnet mask. There is also a class A and a class B that are comprised of bits.

How many bits are reserved for OUI in mac address?
There are 24 bits, or six hex characters, for the preamble of the MAC address (i.e., 00:11:22 in the MAC address 00:11:22:33:44:55 or 0011.2233.4455).

What is the main format of an IP address?
In IPv4, which is the current standard for IP addressing, an IP address is 32 bits. The most commonly used format is called dotted decimal, which means that the 32 bits is broken into 4 octets of 8 bits each, and represented with their decimal equivalent separated by decimal points. Since the decimal equivalent of an octet ranges between 0 and 255, this means that an IP address ranges from 0.0.0.0 to 255.255.255.255. However, not all addresses are valid1. In IPv6, which is the new emerging standard, an IP address is 128 bits. The most commonly used format is hexadecimal colon format, where each group of 16 bits is represented by four hexadecimal digits and separated by a colon. Sequential groups of 16 zeroes are represented by two colons. An example IPv6 address is 2001:0DB8:AC10:FE01:0000:0000:0000:0000, which can be abbreviated 2001:0DB8:AC10:FE01::. ---------------------------------------------------------------------- 1Generally, the lowest address in a subnet is reserved for routing, and the highest address in a subnet is reserved for broadcast. Also, there are some special addresses, with reserved meanings.
How many characters does a MAC address have?

What is the size of address bus in 8086?
The address bus in the 8085 is 16 bits wide.
How many host address are there for an address with 21 bits for the network address?
2046 Breakdown: 11111111.11111111.11111000.00000000 /21 - 21 bits in network address represented by ones in binary address above. Leaves 2^11th power host addresses left (the zeros to the right). Equals 2048 host addresses minus the two reserved addresses = 2046

How do you determine what bits to use to calculate the network address?
An IP address comes in two formats: ipV4 and ipV6. In IpV4 32 bits are allocated to the IP address. In IpV6, 128 bits are allocated to the address. This is done by the protocol and is a standard for developing an IP address.
