This is the answers to the question for project 8.
1) A computer network is all client computer, server computer and any supporting hardware and software that is interconnected by transmission media.
No, because the terminals are not pc and is considered part of the mainframe.
Yes because your computer is a client and the dial up connection is the communication data connection and your computer request and recieves data from the mainframe which when the PC recieves the data it is then processed.
2)Application: Is the layer where the user uses to create the data (e.g. Http, e-mail, File transfer)
Presentation: The layer where the two host negotiates the way data is encoded and managed.
Session: Maintains order in the session, starts, stops the session.
Transport: This layer purpose is to maintain end to end connectivity. This layer is where the data is encapsulated into segments.
Network: This layer establishes the route between stations. This layer is where the router resides. This layer is where the segments is encapsulated into packets.
Data Link:This layer is where the packets are further encapsulated into frames and it is sent out based on the mac address. This layer is where the switch, bridge and the NIC is located.
Physical: This is where the physical media is located and the electrical and or light is transmitted.
3)Protocols are rules that governs the transmitting and receiving of data.
http, ip, igrp, udp, rip.
4)A pattern of interconnection between nodes. An example of a physical topology is ethernet where all the nodes are arranged in a star pattern. Another topology is the token ring where all the nodes are in a ring pattern and finlly the bus topology where all the nodes are arranged in a line.
5)The speed at which the ethernet is 10 kbps, 100 kbps and 1000 kbps.
cat 5, cat 5e, cat 6, fiber optics.
6)Peer to Peer network is where all the pcs and workstation to act as a server. Where the client/server is where there is a computer or a group of computer that supplies the data which is called a server and a group of computer that recieves the data which is called the client.
7)A hub is a devise that connects several host in a star topology.
8)Is a devise that connects to other routers in the network and or the internet. It is used to forward packets based on IP addresses.
