RARP (Reverse Address Resolution Protocol)

RARP provides a method of dynamically mapping 48-bit MAC address to the corresponding 32-bit IP

address. RARP has now been replaced by the Bootstrap Protocol (BOOTP) and the modern Dynamic

Host Configuration Protocol (DHCP).

13.

Socket

Each TCP segment contains a source and destination port number that can be used to identify the

sending and receiving application. These two values, along with the source and destination IP
addresses in the IP header, uniquely identify each connection. The combination of an IP address

and a port number is called a socket.

14.

Subnet Mask

A Subnet mask, often simply called the “Mask”, is a 32-bit number that masks and IP address, and
divides the IP address into the network address and the host address. Given its own IP address and

its subnet mask, a host can determine whether a TCP/IP packet is destined for a host that is (1) on

its own subnet, or (2) on a different network. If (1), the packet will be delivered directly; otherwise

it, will be delivered via a gateway or a router.

15.

TCP (Transmission Control Protocol)

TCP is a set of rules used in combination with the Internet Protocol to send data in the form of
message units between computers over the Internet. TCP provides a reliable flow of data between

two hosts and is associated with tasks such as dividing the data passed to it from an application into

appropriately sized chunks for the network layer below, acknowledging received packets, setting

timeouts to make certain that the other end acknowledges packets that are sent, and so on.
