Tham khảo Bài giảng Mạng máy tính căn bản - Chương 5: Hệ thống cáp của LAN và WAN (Cabling LAN and WAN) người học có thể xác định đặc điểm của Ethernet mạng, xác định thẳng, chéo, và cáp rollover, mô tả chức năng, ưu điểm và nhược điểm của bộ lặp, các thành phần mạng không dây,. | Chương 5 HỆ THỐNG CÁP CỦA LAN VÀ WAN CABLING LAN AND WAN Overview Even though each local-area network is unique, there are many design aspects that are common to all LANs. For example, most LANs follow the same standards and the same components. This module presents information on elements of Ethernet LANs and common LAN devices. Phan Vĩnh Thuần There are several wide-area network (WAN) connections available today. They range from dial-up to broadband access, and differ in bandwidth, cost, and required equipment. This module presents information on the various types of WAN connections. Phan Vĩnh Thuần Students completing this module should be able to: Identify characteristics of Ethernet networks. Identify straight-through, crossover, and rollover cables. Describe the function, advantages, and disadvantages of repeaters, hubs, bridges, switches, and wireless network components. Describe the function of peer-to-peer networks. Phan Vĩnh Thuần Describe the function, . | Chương 5 HỆ THỐNG CÁP CỦA LAN VÀ WAN CABLING LAN AND WAN Overview Even though each local-area network is unique, there are many design aspects that are common to all LANs.

Describe and differentiate between serial, Integrated Services Digital Network (ISDN), digital subscriber line (DSL), and cable modem WAN connections. Identify router serial ports, cables, and connectors. Identify and describe the placement of equipment used in various WAN configurations. Phan Vĩnh Thuần . Cabling the LAN . LAN physical layer Various symbols are used to represent media types. Token Ring is represented by a circle. Fiber Distributed Data Interface (FDDI) is represented by two concentric circles and the Ethernet symbol is represented by a straight line. Serial connections are represented by a lightning bolt. Phan Vĩnh Thuần Phan Vĩnh Thuần Each computer network can be built with many different media types. The function of media is to carry a flow of information through a LAN. Wireless LANs use the atmosphere, or space, as the medium. Other networking media confine network signals to a wire, cable, or .
