With TCP/IP connections, a computer can function either as the client or the server. The following block diagram represents a client application that initiates a connection to a remote server with TCP Open Connection. The server, or daemon, listens for remote connections and responds appropriately...

Below is a diagram of the TCP/IP protocol suite. Note that in the Host-to-Host layer, Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are defined for transmitting datagrams. We will look at the details of both these protocols as well as their interaction with the uppe...
This diagram shows the most common implementation, which uses 32 bits for the layer three (“Protocol”) addresses, and 48 bits for the layer two hardware addresses. These numbers of course correspond to the address sizes of the Internet Protocol version 4 and IEEE 802 MAC addresses, used by...
TCP employs the positive acknowledgement with retransmission technique for the purpose of achieving reliability in service. Figure 19: The positive acknowledgement with retransmission technique. Figure 19 illustrates a simple ladder diagram depicting the events taking place between two hosts. The arrows repr...
