Answer: Broadband 62. ____________ measures cycles per second, and baud is the number of signals sent per second. Answer: Hertz Essay Questions 63. Compare LANs, WANs, and MANs. Answer: A local area network (LAN) is designed to connect group of computers in close proximity to each other such as in an office building, a school, or a home. A wide area network (WAN) spans a large geographic area, such as a state, province or country. WANs often connect multiple smaller networks, such as local area networks (LANs) or metropolitan area networks (MANs). A metropolitan area network (MAN) is a large computer network usually spanning a city. 64. List and describe the four components that differentiate networks. Answer: Networks are differentiated by the following, architecture—peer-to-peer, client/server, topology—bus, star, ring, hybrid, wireless, protocols—Ethernet, Transmission Control Protocol, media—coaxial, twisted-pair, fiber-optic. 65. Compare the two types of network architectures. Answer: A peer-to-peer (P2P) network is any network without a central file server and in which all computers in the network have access to the public files located on all other workstations. A client is a computer that is designed to request information from a server. A server is a computer that is dedicated to providing information in response to external requests. A client/server network is a model for applications in which the bulk of the back-end processing, such as performing a physical search of a database, takes place on a server, while the front-end processing, which involves communicating with the users, is handled by the clients 66. Explain topology and the different types found in networks. Answer: Network topology refers to the geometric arrangement of the actual physical organization of the computers and other network devices) in a network. The five common types found in networks include: Bus-All devices are connected to a central cable, called the bus or backbone. Bus networks are relatively inexpensive and easy to install for small networks. Star-All devices are connected to a central device, called a hub. Star networks are relatively easy to install and manage, but bottlenecks can occur because all data must pass through the hub. Ring-All devices are connected to one another in the shape of a closed loop, so that each device is connected directly to two other devices, one on either side of it. Ring topologies are relatively expensive and difficult to install, but they offer high bandwidth and can span large distances. Hybrid-Groups of star-configured workstations are connected to a linear bus backbone cable, combining the characteristics of the bus and star topologies. Wireless-Devices are connected by a receiver/transmitter to a special network interface card that transmits signals between a computer and a server, all within an acceptable transmission range. 67. Describe TCP/IP along with its primary purpose. Answer: Transmission Control Protocol/Internet Protocol (TCP/IP) provides the technical foundation for the public Internet as well as for large numbers of private networks. 68. Identify the different media types found in networks Answer: Wire media are transmission material manufactured so that signals will be confined to a narrow path and will behave predictably. The three most commonly used types of guided media are twisted-pair wiring, coaxial cable, fiber-optic cable, wireless media are natural parts of the Earth's environment that can be used as physical paths to carry electrical signals. 69. Compare LANs, WANs, and MANs. Answer: A local area network (LAN) is designed to connect group of computers in close proximity to each other such as in an office building, a school, or a home. A wide area network (WAN) spans a large geographic area, such as a state, province or country. WANs often connect multiple smaller networks, such as local area networks (LANs) or metropolitan area networks (MANs). A metropolitan area network (MAN) is a large computer network usually spanning a city. 70. Describe the business benefits associated with VoIP. Answer: VoIP uses existing network and Internet infrastructure to route telephone calls more efficiently and inexpensively than traditional telephone service, VoIP offers businesses significant cost savings, productivity gains and service enhancements. 71. Explain the difference between a VPN and a VAN. Answer: A virtual private network (VPN) is a way to use the public telecommunication infrastructure (e.g., Internet) to provide secure access to an organization's network. A valued-added network (VAN) is a private network, provided by a third party, for exchanging information through a high-capacity connection. 72. Identify the advantages and disadvantages of broadband technology. Answer: Digital Subscriber Line (DSL)-Good upload rates, uses existing telephone lines, but speeds vary depending on distance from telephone company's central office and slower downloads than less expensive alternatives. Cable-uses existing cable infrastructure, low-cost equipment, but shared connections can overload system, slowing upload times. TI/T3 Dedicated Line - uses existing phone wiring, but performance drops significantly with range and susceptible to crosstalk. Fiber-to-the-Home (FTTH)-fast data speeds, infrastructure has long life expectancy, low maintenance, low power costs, but not widely available and significant deployment cost (for company). Fixed Wireless-typically inexpensive to install, no underground digging, but weather, topography, buildings, and electronics can cause interference. Satellite-nearly universal coverage, available in otherwise inaccessible area, but expensive service/equipment and upload/download delays. 73. List and describe many of the network security problems. Answer: An organization has to be concerned about proper identification of users and authorization of network access, the control of access, and the protection of data integrity. Almost all networks require some kind of logon, including user name and password. Many people are casual with their passwords, making them easy to guess. A good password has both letters and numbers along with a few punctuation marks for added security. Most corporate security goes far beyond passwords such as using a "firewall," a computer that sits between an internal network and the Internet. The firewall allows access to internal data from specified incoming sites but tries to detect unauthorized access attempts and prevent them from occurring.
