Understanding TCP/IP will help you configure, maintain, and troubleshoot many systems that a network engineer will encounter.
The chapter began with a discussion of the TCP/IP protocol suite. This included a comparison of the two common reference models: the Open Systems Interconnect (OSI) Model and the Department of Defense (DOD) Reference Model. During the discussion I delved into the various layers in the models and provided examples of how the various components in TCP/IP are implemented.
Next I moved into a discussion on hardware addresses. These addresses, also known as MAC addresses, are used to uniquely identify the network interface card (NIC) in a computer.
The next section described IP addressing. IP addressing is the heart of a TCP/IP-based network. An IP address is a 32-bit binary number that identifies a computer on a network. It contains two parts: the network portion and the host portion of the address. This section also included a discussion of IP address classes and how they are employed.
