1. LAN,MAN & WAN NETWORKS PRESENTED BY: AHSAN SHARIF ROLL NO: 01-PD-21/26

2. TOPICS TO BE DISCUSSED Local Area Network (LAN) : Characterisitics , Use Cases & Example Scenario Metropolitan Area Network (MAN): Characterisitics , Use Cases & Example Scenario Wide Area Network (WAN): Characterisitics , Use Cases & Example Scenario Main Differences Between LAN,MAN & WAN.

3. CHARACTERISTICS USE CASES EXAMPLE SCENARIO Scope: Limited to a small geographical area, such as a single building or campus. Office Network: Connecting computers, printers, and servers within an office building. Office Building: A small business with multiple employees in one office building needs to connect all its computers, printers, and servers. A LAN would be most suitable as it provides high-speed, low-latency connections within a limited area. Speed: High-speed, typically ranging from 100 Mbps to 10 Gbps . Home Network: Connecting personal devices like computers, smartphones, and smart home devices. Ownership: Usually owned, managed, and maintained by a single organization. Campus Network: Used in universities to connect different departments and resources within the campus. Technology: Utilizes Ethernet, Wi-Fi, and sometimes fiber optics LOCAL AREA NETWORK (LAN)

4. CHARACTERISTICS USE CASES EXAMPLE SCENARIO Scope: Covers a city or a large campus, spanning several kilometers. City-Wide Network: Connecting multiple offices or campuses within a city. City government : A municipal government needs to connect various buildings like the city hall, public libraries and police stations across a city. A MAN would be ideal to provide reliable and high speed connectivity between these sites. Speed: High to moderate speed, typically lower than LAN but higher than WAN, often ranging from 10 Mbps to 1 Gbps. Campus Network : Extending connectivity across a large university or enterprise campus spread across multiple locations within a city. Ownership: May be owned by a single organization or managed by a service provider. Public Services: Used by municipalities to connect public service networks like emergency services, libraries, and government buildings. Technology: Utilizes fiber optics, wireless, or copper cables, often employing technologies like MPLS (Multiprotocol Label Switching) and Metro Ethernet. METROPOLITAN AREA NETWORK(MAN)

5. CHARACTERISTICS USE CASES EXAMPLE SCENARIO Scope: . Covers a large geographical area, potentially spanning countries or continents. Global Enterprise Network: Connecting multiple offices or branches of a large corporation spread across different countries. Global Corporation: A multinational company needs to connect its headquarters in the United States with its offices in Europe and Asia. A WAN would be the most suitable network, as it provides the necessary connectivity across vast distances. Speed : Moderate to low speed, typically ranging from 1.5 Mbps (T1 lines) to 100 Mbps or higher, depending on the technology and distance. Telecommunications Networks: Connecting cellular towers and providing backbone connectivity for ISPs (Internet Service Providers). Ownership: Often involves multiple service providers and may be owned by various organizations. Internet: The largest WAN, connecting millions of private, public, academic, business, and government networks worldwide. Technology: Utilizes leased lines, satellite links, fiber optics, and technologies like MPLS, VPN (Virtual Private Network), and SD-WAN (Software-Defined WAN). WIDE AREA NETWORK (WAN)

6. LAN MAN WAN Geographical Scope: LAN is confined to a small area (e.g., a building) MAN covers a city or large campus WAN spans vast distances (e.g., countries or continents). Speed: LAN typically offers the highest speeds due to its limited range MAN offers moderate speed WAN generally offering lower speeds due to its vast coverage. Ownership: LAN is usually owned and managed by a single entity MAN may be owned by one or more organizations or managed by a service provider WAN involves multiple service providers and complex ownership structures. Technology: LAN uses technologies like Ethernet and Wi-Fi MAN uses fiber optics and Metro Ethernet WAN uses a variety of technologies including leased lines, MPLS, and satellite links.
