The idea is that every address would be made up from four groups of eight binary numbers. Each group of eight binary numbers is known as an octet. Because we struggle to write numbers out in binary we usually convert them into decimal but computers and network devices still see all numbers in binary because they can only recognize on and off signals so either a 0 or a 1. How it Works Each number you allocate to a host on your network will be in groups of four separated by a dot e.g. 192.168.1.23.
TCP is the transport layer protocol that links the application layer to the network layer. TCP breaks the data into smaller packets, numbers the packets, ensures each packet is reliably delivered, and puts the packets in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the computers through which the message passes through; IP routes the message to the final destination. TCP/IP is the transport & network layer protocol used on the Internet.

8. A computer with a host IP address of 10.10.5.1 sends a data packet with a destination IP address of 10.10.52.2. A subnet mask of 255.255.255.0 is being used. Determine whether the packet stays in the LAN or is sent to the gateway. Show your work.
You are a consultant working on a site plan for a medium-sized organization. The organization consists of a main office and three branch offices. Two of the locations have standard IP links to the main office, while the third branch office is a separate domain and uses an Internet connection for e-mail. How should you configure the site links for the three branch offices to the main office? A: RPC over IP for the two standard link branch offices and use SMTP for the remote site.
With hypertext, a word or phrase can contain a link to another Web site. 3 What is a computer network? A collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another allowing for data to be shared and used. A great example of a network is the Internet. 4 What is the difference between an intranet and an extranet?
