Source: sowhat1412 Author: sowhat1412 1 TCP/IP 1.1 TCP/IP Definition TCP/IP protocol suite is a set of protocols, also known as Internet Protocol Suite. Computers can communicate only by adhering to these rules. TCP and IP are just two of the important protocols, hence the name TCP/IP for this internet protocol suite, which actually includes four … Read more
Why TCP/IP Exists All around the world, various computers running different operating systems serve their purposes. However, the methods they use to express the same information can vary greatly. It’s akin to how God confused the languages of people in the Bible, preventing them from cooperating. Computer users realized that individual computers would not be … Read more

1. Architecture The TCP/IP protocol suite is a four-layer protocol system. Figure 1 TCP/IP Architecture Data Link Layer: Implements the network driver for the network interface card, handling the transmission of data over physical media (Ethernet, Token Ring). The network driver abstracts the electrical characteristics of different physical networks. The data link layer uses ARP … Read more
Static IP Routing A Simple Routing Table Routing is one of the most important functions at the IP layer. The previous sections have briefly discussed how routers select routes based on the IP addresses of IP packets. We will not repeat that here. First, let’s take a look at a simple system routing table. Destination … Read more

What Are TCP Segmentation and IP Fragmentation We know that a network is like a pipe, and pipes can have different diameters. When a data packet wants to travel from one end of the pipe to the other, it must pass through this pipe. (Obvious, right?) However, the size of data packets can be varied, … Read more
