Chapter 1: Question 7, 14, and 17
Question 7. How do local area networks (LANs) differ from metropolitan area networks (MANs), wide area networks (WANs), and backbone networks (BNs)? Most LAN’s are connected to (BNs) backbone networks that connect multiple LAN’s, BN’s, MAN’s and WAN’s and can range in size and distance from several hundreds of feet to miles and can have data transmission speed ranging from 100 – 1000 Mbps. (LANs) local area networks are a cluster of computer that are contained in a confined area examples: office floor, building, or multiple buildings. All connected computers on the LAN use shared circuits and LAN’s use high speed data transmission operation at 100Mbps .LAN’s can be standalone networks or are the basis for MAN’s WAN’s, and BN’s. MANs can span from 3 – 30 miles, and connect LAN’s and BN’s backbone networks together from different areas and have data transmission speeds from 64 Kbps to 10 Gbps. MAN’s are city to county sized networks. (WAN’s) wide area networks connect MAN’s and BN’s and are made up of satellites, microwave towers and laying cable. These are very expensive and most organizations lease IXC’s from major telecommunication companies ( AT&T, Sprint, and Verizon). WAN’s can be designed in many sizes and types and can span several thousands to only hundreds of miles examples (cities, states, and countries) and data transmission speed from 64 Kbps to 10 Gpbs. Question 14. Explain how a message is transmitted from one computer to another using layers. Using the five layer Internet model - A message transmitted from one computer to another would start in the application layer where letters, numbers, and keystrokes of the message are converted into HTTP packet. The message would then be send through the transport layer, which would establish, maintain, and terminate the connection between the computers for
