WANs are fairly common too, as businesses embrace mobility and more of them span greater distances. Today, LANs exist in many homes (wireless networks) and nearly all businesses. Generally, it's safe to think of a WAN as multiple, disbursed LANs connected together. Expanding upon that, a wide area network (WAN) includes networks outside the local environment and can also distribute resources across great distances. The local area network (LAN) was created to connect computers in a single office or building. It used to be that in order to be a PC technician, you needed to focus on only one individual (but large) computer at a time. This chapter focuses on the basic concepts of how a network works, including the way it sends information, the hardware used, and the common types of networks you might encounter. A set of rules called Carrier Sense Multiple Access / Collision detection are used to detect and prevent collision in networks. As several devices are connected to network, it is important to ensure data collision does not happened when this devices attempt to use data channel simultaneously. Several major LAN can be connect together to form a WAN. WAN is a network that covers wider area than LAN and usually covers cities, countries and the whole world. There are many types of network available in the networking industries and the most common network are Local Area Network (LAN) and Wide Area Network (WAN).LAN network is made up of two or more computers connected together in a short distance usually at home, office buildings or school. These are the devices that play an important role in data transfer from one place to another using different technology such as radio waves and wires. Basically, network consists of hardware component such as computer, hubs, switches, routers and other devices which form the network infrastructure. The advantage of networking can be seen clearly in terms of security, efficiency, manageability and cost effectiveness as it allows collaboration between users in a wide range. Resources such as files, applications, printers and software are common information shared in a networking. Want more details?
