Exercises 8-3 You have been hired by a small company to install a backbone to connect four 100base-T Ethernet LANs (each using one 24-port hub) and to provide a connection to the Internet. Develop a simple backbone and determine the total cost (i.e.‚ select the backbone technology and price it‚ select the cabling and price it‚ select the devices and price them‚ and so on). Prices are available at www.datacommwarehouse.com‚ but use any source that is convenient. For simplicity‚ assume that category

HOMEWORK WEEK 5 3. Compare and contrast the two types of antennas. There are mainly two types of antennas: omnidirectional‚ and directional. Omnidirectional antennas are installed on most WLANS with AP’s that have them. Omnidirectional antennas do just what they sound like‚ which is transmit data in all directions at the same time. The signal can go horizontally and vertically; and up and down. However‚ there can be a dead spot in a minute area directly above the antenna which has no signal.

MIS 589 Chapter 1 Questions 7. How do local area networks (LANs) differ from metropolitan area networks (MANs)‚ wide area networks (WANs)‚ and backbone networks (BNs)? Local area networks (LANs) consist of microcomputers located in a same general area. LANs usually share circuits where computers take turns using the same circuit. In a metropolitan area networks (MANs)‚ a network usually covers a citywide area. Wide area networks (WANs) span a large geographical area. WANs span a larger area

HOMEWORK QUESTIONS WEEK 4 3.) What are the parts of TCP/IP and what do they do? Who is the primary user of TCP/IP? TCP/IP is the transport/network layer protocol we use on the internet. Many BN’S‚ MAN’s and WAN’s rely on it. This is because it is relatively efficient‚ and transmission has few errors. Any errors that are found‚ are checked and so large files can be sent even in the most unsafe network and the data will still be unchanged. TCP/IP is very compatible with a number of data link protocols

HOMEWORK WEEK 6 9.) Compare and contrast circuit-switched services‚ dedicated-circuit services‚ and packet-switched services. Circuit switched services are the oldest approach to MAN and WAN circuits. They began operating over the PSTN or the Public Switched Telephone Network that carriers like AT&T‚ and Bell South ran on. A simple telephone call is based off of this premise. Circuit switched services rely on cloud architecture. This means that the users must lease connection points into the
