- 1. INTRODUCTION OF LAN , MAN & WAN
- 2. Computer Networks Computer network connects two or more autonomous computers. The computers can be geographically located anywhere.
- 3. LAN, MAN & WAN Network in small geographical Area (Room, Building or a Campus) is called LAN (Local Area Network) Network in a City is call MAN (Metropolitan Area Network) Network spread geographically (Country or across Globe) is called WAN (Wide Area Network)
- 4. Applications of Networks Resource Sharing Hardware (computing resources, disks, printers) Software (application software) Information Sharing Easy accessibility from anywhere (files, databases) Search Capability (WWW) Communication Email Message broadcast Remote computing
- 6. Local Area Networks Local Area Networks (LANs) Local Area Networks are privately-owned networks within a small area, usually a single building or campus of up to a few kilometers. Since it is restricted in size, that means their data transmission time can be known in advance, and the network management would be easier.
- 7. Local Area Networks Cost reductions through sharing of information and databases, resources and network services. Increased information exchange between different departments in an organization, or between individuals. Improve the community security. Increasing number and variety of intelligent data terminals, PCs and workstations. Advantages Of Local Area Networking
- 8. Local Area Networks (LAN)
- 10. Metropolitan Area Network A Metropolitan Area Network (MAN) is a network that is utilized across multiple buildings Commonly used in school campuses or large companies with multiple buildings Is larger than a LAN, but smaller than a WAN Is also used to mean the interconnection of several LANs by bridging them together. This sort of network is also referred to as a campus network
- 11. Metropolitan Area Networks (MAN) A Metropolitan Area Network is a system of LANs connected throughout a city or metropolitan area. MANs have the requirement of using telecommunication media such as voice channels or data channels. Branch offices are connected to head offices through MANs. Examples of organizations that use MANs are universities and colleges, grocery chains, and banks.
- 15. Wide Area Networks (WAN) The main difference between a MAN and a WAN is that the WAN uses Long Distance Carriers. Otherwise the same protocols and equipment are used as a MAN.
- 17. Wide Area Network A Wide Area Network is a network spanning a large geographical area of around several hundred miles to across the globe May be privately owned or leased Also called “enterprise networks” if they are privately owned by a large company Can be connected through cable, fiber or satellite Is typically slower and less reliable than a LAN Services include internet, Intranet ,etc. 17
