Nt1210 Network Essay
1. A LAN or local area network is a group of computers all located in the same area that are usually connected via some means. (Wireless or wired).
2. 3 types of servers are FTP, web, and application server. A file transfer protocol server is used to secure transfer files between 2 computers while providing ease of use (transfer protocols). A web server serves content to the web browser and allows the content to be displayed on user web browsers, all done with the aid of http. Lastly, an application server hold a lot of data that connect to the both the user and a database usually to access data, update data or remove data.
3. The basic components of wired LAN consist of clients, servers, NICs, network cables, hubs/switches and software. The way it works is that the Ethernet being used is either Hub-based or switched based. Generally, every computer is connected to one another through wires. It must not be directly connected as the message can be resent through another computer that the message wasn’t intend for or through a switch sending it to the correct location.
10. Both logical and physical topology show how the network layout looks. With logical you see it theoretically and with physical is shows how exactly the network is really installed.
11. CSMA/ CD is carrier sense …show more content…
Cut through, store and forward, and fragment free switching are all forms of switching modes. With cut-through it is quicker but wastes capacity as it retransmits frames as soon as the destination address is read; it does not wait to receive the entire packet. Store and forward is a much more effective method as it has few errors because it retransmits the frames once the entire frame is received and then does an error check but it is thus slower. Lastly, the fragment free switching is a middle ground between the two latter. It retransmits the frames after the first 64 bytes (which consist of the header) is received and has no errors. It is in between the two latter in
