Local Area Networks (LANs) have become an integral part of communication in today's world. LAN applications are used in businesses, educational facilities, hospitals, stock exchanges, and warehouses to name a few. Forouzan's Local Area Networks offers reader-friendly, comprehensive coverage of LAN technologies, which prepares students the reader to use these technologies in real-world applications. Local Area Networks is ideal for students both in the classroom and later as a reference. Forouzan motivates topics by practical applications, and his liberal use of figures makes difficult technical topics easier to grasp by providing an intuitive, visual representation of concepts. Extensive practice sets are also provided at the end of each chapter, which reinforce what the student has learned. Forouzan's Local Area Networks is also up-to-date. It presents in-depth material on such current topics as Gigabit Ethernet, ATM LAN, Wireless LAN, VPN, and VLAN.
