When computers communicate with each other, there needs to be a common set of rules and instructions that each computer follows. These communication rules are called protocols. Because of the many ways computers can communicate with each other, there are many different protocols. Some examples of these different protocols are HTTP (Hypertext Transfer Protocol) and FTP (File Transfer Protocol).
A server is the central pont of a network. When users connect to a server, they can access programs, files, and other information from the server. Common servers are Web servers, Mail servers, Print Servers and LAN servers. You usually have to have a username and password to gain access to the information on that server.
A topology is the way in which computers are connected to create a network. Common configurations include the bus topology, mesh topology, ring topology, star topology and tree topology. |
