On a ‘Local Area Network’ data transfer speeds are higher than WAN and MAN that can extend to a 10.0 Mbps (Ethernet network) and 1.0 Gbps (Gigabit Ethernet). 0000001598 00000 n Metropolitan Area Network (MAN): A metropolitan space network (MAN) could be a network that interconnects users with pc resources in an exceedingly geographic space or region larger than that lined by even an oversized local area network (LAN) however smaller than the realm lined by a wide area network (WAN). . MAN (Metropolitan Area Network) MAN is a computer network that interconnects users with computer resources in a geographic area or region larger than that covered by a LAN(Local Area Network) but smaller than the area covered by a WAN(Wide Area Network). That is, one network can be connected to another network and be-come a more powerful tool because of the greater resources. In LAN all machines are connected to a single cable. 199 14 It is important to realize that most of the higher level protocols used on LANs are exactly the same protocols that are used in most ‘networks’. 0000000576 00000 n By sending data through the router, all the computers on the local area network could send data across the “Wide Area Network” (or WAN). . trailer This network could be as small as two computers that are connected to each other or large, with thousands of devices connected. xref 0000002047 00000 n When you read about WAN technologies and protocols, there is a lot of terminology you might encounter. Let me walk you through the different items in the picture: 1. 0000003422 00000 n . Before we begin discussing networking with any depth, we must define some common terms that you will see throughout this guide, and in other guides and documentation regarding networking.These terms will be expanded upon in the appropriate sections that follow: 1. . Broadly speaking, there are two types of network configuration, peer-to-peer networks and client/server networks.

It is used to connect two or more personal computers through a communication medium such as coaxial cable, twisted pair, etc. 2 LAN Components A LAN is a combination of hardware … . They keyword here is “local”. Let’s look at a picture: The picture above is what a WAN solution in general looks like. You take your first step toward networking and data communications exposure, and gain the practical knowledge and skills to become comfortable with basic concepts, technologies, components, and design alternatives. LAN – Local Area Network: A network that spans a small geographic area, such as a single building or buildings close to each other. In a simple way, a Local Area Network (LAN) is a group of computers and other devices that are connected together over a network cables and are all in the same location typically within a single building like an organization or home. Introduction-A network can be defined as a group of computers and other devices connected in some ways so as to be able to exchange data.-Each of the devices on the network can be thought of as a node; each node has a unique address.-Addresses are numeric quantities that are easy for computers to work with, but not for humans to remember. 2y�.-;!��K�Z� ��^�i�"L��0��-�� @8(��r�;q��7�L��y��&�Q��q�4�j��|�9�� MAN – Metropolitan Area Network: A network that can span a geographic area the size of a city. This hands-on Introduction to Networking course will enable you to take a more active part in the discussion and decision-making processes related to networking technology issues. 0000001301 00000 n MAN is larger than a local area network and as its name implies, covers the area of a single city. Approximately all current LANs whether wired or wireless are based on Ethernet. This computer networking PDF walks you through how to build a network that supports application diversity. 802.11 Wireless networks Standards for Interoperable LAN/MAN Security (SILS) (Network Security) 802.10 802.9 Integrated Voice and Data Networks 802.8 Fiber-Optic Technical Advisory Group 802.7 Broadband Technical Advisory Group 802.6 Metropolitan Area Network (MAN) 802.5 Token Ring networks 802.4 A token passing bus This paper discusses 2.

Introduction Support for wireless local area networks (WLANs) in corporate offices and employee’s homes is becoming a necessary activity for networking professionals, requiring new knowledge and training. %PDF-1.4 %�� Elaine_06_I-6 Overview • Ethernet is the most popular LAN technology - large installed base (500 million Ethernet nodes) While some networks limit the number of connected machines, others grow as large as a global wide area network (WAN). A local area network is a high-speed, medium-distance communication system. A WAN spans a large physical distance. A Local Area Network (LAN) is a network that is restricted to smaller physical areas e.g. Local area networks use this low-east, high-speed transmission capabality as the basis for a general-purpose data transfer network. .
