Computer networks consist of communications, media, devices, and software need to connect two or more computer systems or devices. Networks are able to transmit and receive information to improve organizational effectiveness and efficiency. Assuming our company is not peer to peer networking; our company seems to be a server based network side. With a server based network all accounts and data files are stored on the server. However if the server goes down no one can access their accounts or the files. The server based network offers an array of different services. The services it offers are file and print, application, web, and directory. One network design model is the bus topology. The bus uses on main cable called the backbone, which connects the computer, printer, and everything to the server. Some advantages of the bus topology are the cost. Also the installation, because there is no additional devices required. If a computer fails along the bus topology the rest of the system stays up and running. However a major disadvantage of the bus topology is troubleshooting. Most problems in the bus are a break in the segments.

Another network model is the mesh topology. In the mesh every computer has a connection to all the components of the network. Advantage of the mesh topology is if a cable breaks, the signals could and can be routed through different paths. With the mesh it is nearly impossible for a network to go down. Some disadvantages of the mesh topology are the cost, because of the extra cable used to connect the network with all components. Troubleshooting is a large disadvantage because of all the numerous connections.

For our company I think a combination of the tree, start and ring topology would work because of all the devices that need access: * 10 computers
* 2 printers for everyone
* 1 color printer accessible...
