Compare and contrast the three types of addresses used in a network.

The three types of addresses used in a network are the application layer, network layer and the Data link layer. When users work with application software, they typically use the application layer address. Application software that used Internet addresses (e.g., ). This is an application layer address. When a user types an Internet address into a Web browser, the request is passed to the network layer as part of an application layer packet formatted using the HTTP protocol. The network layer software, in turn, uses a network layer address. The network layer protocol used on the Internet is IP, so this Web address ( ) is translated into an IP address that is 4 bytes long when using IPv4 (e.g., 129.79.127.4). This process is similar to using a phone book to go from someone's name to his or her phone number. The network layer then determines the best route to transmit the data. Now the data link layer protocol is used which attaches an Ethernet address frame to the packet which contains the MAC address of the receiver computer. This Mac address is examined with many computers over the network until it reaches its target Ethernet address or Computer.
