Like any other data communication network, a local area network is composed of three basic hardware elements: a transmission medium, often twisted pair, coaxial cable, or fiber optics; a mechanism for control of transmission over the medium; and an interface to the network for the host comput- ers or other devices-the.

Although this term is beginning to lose its popular use, the concept of the network outgrowing its local confines and requiring addi-. At the same time, the telecommunication and computer industries became interested in computer networks. The telecommunication industry bet on the X25. The computer industry took a completely different approach by designing Local Area. Networks (LAN). Many LAN technologies such as Ethernet or Token Ring were. Types of Networks. There are two principle kinds of networks: Wide Area Networks. (WANs) and Local Area Networks (LANs).

A LAN is a network that is used for communicating among computer devices, usually within an office building or home. • LAN's enable the sharing of resources such as files or hardware devices that may be needed by multiple users. •. • Is limited in size, typically spanning a few hundred meters, and no more than a mile. “No man but a blockhead ever wrote, except for money." - Samuel Johnson.

Local Area Network. ▫ LANs connect computers and peripheral devices in a limited physical area, such as a business, office, laboratory or college campus by means of permanent links (wires) that transmit data rapidly. ▫ A LAN consists of two or more personal computer, printers and high capacity disk storage device called. A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication.

Local area network (LAN) communications security is addressed in this essay. LANs are introduced as providing: (1) a private communications facility, (2) services over a relatively limited geo- graphic area, (3) a high data rate for computer communications, and (4) common access to a wide range of devices and services. Introduction. Wireless technology has helped to simplify networking by enabling multiple computer users to simultaneously share resources in a home or business without additional or intrusive wiring. These resources might include a broadband Internet connection, network printers, data files, and even streaming audio.

A server is simply a computer, that available the network resources and provides service to other computers when they request it. A client is the computer running a program that requests the service from a server. □ Local area network(LAN) is based on client server network relationship. In the past all local area networks were wired together and in a fixed location. Wireless technology has helped to simplify networking by enabling multiple computer users simultaneously share.

I will discuss securing a LAN from the viewpoint of the network architect considering three main areas: the network topology which comprises the physical and logical design of the network; securing the. software and hardware tools and lab activities designed to enhance teaching and learning various aspects of computer networking. Chapter II describes the development and use of an interactive software tool (named WebLan-Designer) as an aid to enhance teaching and learning both wired and wireless LAN de- sign. A local area network (LAN) is a computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings. A LAN is composed of inter-connected workstations and personal computers which are each capable of accessing and sharing data and devices, such as. Local Area Network Overview. LAN Applications (1). Personal computer LANs. Low cost; Limited data rate. Back end networks. Interconnecting large systems (mainframes and large storage devices). High data rate; High speed interface; Distributed access; Limited distance; Limited number of devices. LAN Applications (2). Allowing someone to log onto the network. ➢ Even giving a workstation an address on the network is a service. If your computer does not have an address, it cannot access the internet or any other resource on the network.

A computer network is an interconnection of various devices like laptops, routers, switches, servers, etc. with the help of wired or wireless means. These networks can be differentiated on the basis of their reach, i.e., geographical area. For example, we have local area network, wide area network, personal.
