FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -TCP/IP supports three classes of Internet addresses: Class A, Class B, and Class C. The different classes of Internet addresses are designated by how the 32 bits of the address are allocated. The particular address class a network is assigned depends on the size of the network.

Detailed explanation-2: -Class C networks use a default subnet mask of 255.255.255.0 and have 192-223 as their first octet. The address 192.168.123.132 is a class C address. Its first octet is 192, which is between 192 and 223, inclusive.

Detailed explanation-3: -An internet protocol (IP) address allows computers to send and receive information. There are four types of IP addresses: public, private, static, and dynamic.

Detailed explanation-4: -A Class C address consists of a 24-bit network address and an 8-bit local host address. The first three bits in the network address indicate the network class, leaving 21 bits for the actual network address. Therefore, there are 2, 097, 152 possible network addresses and 256 possible local host addresses.
