7. How do local area networks (LANs) differ from metropolitan area network (MAN)? A local area network (LAN) is a group of microcomputers located in the same general area. It covers a clearly defined small area‚ such as an office‚ home network ‚one floor or work area‚ a single building‚ or a group of buildings. While a metropolitan area network (MAN) connects LANs and BNs located in different areas to each other and to WANs. MANs typically span between three and 30 miles. For example a large university

Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. With radio waves distances can be short‚ such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed‚ mobile‚ and portable applications‚ including two-way radios‚ cellular telephones‚ personal digital assistants

point-to-multi-point voice and data transfer. Bluetooth will enable users to connect to a wide range of computing and telecommunications devices without the need for proprietary cables that often fall short in terms of ease-of-use. A global specification for wireless connectivity: Bluetooth‚ named for Denmark’s first Christian king and not a dire dental condition‚ is the name of a technology specification for small form factor‚ low-cost‚ short-range radio links between PCs‚handhelds‚ mobile phones‚ and other

History of LANs Data Communications began in the 1960s with an emphasis on communication over long distances — at least between different cities and often over much greater distances — but at relatively slow data transfer rates. At that time‚ that was what was needed. Most computing was done in batch mode‚ and companies needed an efficient way to transmit data processing files between computer sites. In the 1970s‚ interactive terminals began to proliferate‚ but most data communications took place

MAC Spoofing Don’t rely on MAC filtering alone. Open system authentication (SSID beaconing) Disables SSID from being broadcast so wireless networks are harder
