Difference Between LAN MAN WAN – Computers may connect to and communicate with one another via any medium thanks to the Network. The three networks are called LAN, MAN, and WAN and complete to function in the specific regions they serve. Both of them share and differ from one another in some ways.
The distinctions between LAN MAN WAN
Computers can connect to the Network and communicate with one another through any medium. The three types of networks—LAN, MAN, and WAN—are made to function within the boundaries of the regions they serve. As a result, both their differences and commonalities exist.
The geographic areas they cover, with LAN covering the lowest, MAN covering a size greater than LAN, and WAN making up the largest of all, are one of their key contrasts.
Furthermore, LAN networks depend on the hardware and communication tools they own for transmission. Contrarily, this can’t be the case because MAN and WAN are spread across such a vast area since these networks are required to use public, private, and leased communication devices.
Definition of Local Area Network
Workstations and personal computers can share data, tools, and applications thanks to the Local Area Network, which connects network devices. Due to the restricted number of computers connected, data transfers relatively quickly. Privately operated and with a narrower geographic coverage, LANs. You can use it for a residence, office building, hospital, school, etc. Designing and maintaining a LAN is simple.
Twisted pair wires and coaxial cables make up the LAN communication medium. The inaccuracy and noise reduce because it only travels a limited distance. The ring, bus, and star topologies use to configure LAN. For example, the IBM Token Ring LANs have a common ring topology, while Token Bus and Ethernet have a shared bus topology.
Since every linked host uses the same transmission channel, it is a broadcast network where the message is a relay to every connected host (wire). There are two methods of broadcasting: static broadcasting and dynamic broadcasting. In the static approach, the hosts give a specific time window to transmit the data. While under the dynamic method, the hosts can flexibly broadcast the frame at any time.
Definition of Metropolitan Area Network
A LAN’s coverage area is smaller than a MAN or metropolitan area network, and a WAN’s coverage area is more significant. It links two or more distant computers located in the same city or other cities. It can act as an ISP and has a broad geographic reach (Internet Service Provider). A Metropolitan Area Network is challenging to create and operate.
It is expensive and might not be set aside by a single corporation. The MAN has a moderate data transfer rate.
Types of MAN
DQDB and SMDS are the two forms of MAN that can distinguish.
DQDB (Distributed Queue Dual Bus): Each network host would connect to the two backbone network lines in a dual bus arrangement.
Switched Multimegabit Data Services, SMDS: A network is a protocol that links to various LANs and allows a packet to go from one LAN to any other on SMDS. It is a fast MAN that offers diagram services using packet switching.
Definition of Wide Area Network
WAN or Wide Area Network: A computer network that covers a wide geographic area is known as a WAN. A wide area network (WAN) is a network of local area networks (LANs) linked together via radio waves and phone lines.
Private ownership of the wide area network is possible or unlikely. PSTN or satellite links are two communication methods for wide area networks. However, long-distance transmission makes noise and inaccuracy more common in WANs. One of the most significant issues here is propagation latency.
In contrast to LAN, WAN uses switching, enabling many computers to connect with various switches rather than one another. To transfer packets, it also employs the store-and-forward principle, in which data is temporarily in a buffer before being transmitted along a predetermined path to the destination.
Critical Differences Between LAN MAN WAN
LAN only covers a small portion of the world, MAN a more substantial portion, and WAN the most significant portion.
Compared to MAN, which links small towns or Cities, and WAN, which covers an entire country or a set of countries, LAN is restricted to schools, hospitals, or other structures.
LAN: WiFi and Ethernet cables are the types of equipment utilised for data transfer.
MAN: Modem, wire/cable, and MAN
WAN: optical cables, microwaves, and satellites.
- Over MAN and WAN, LANs transmit data more quickly.
- While MAN and WAN require more maintenance, LAN requires less.
- Compared to MAN and WAN, the LAN has a larger bandwidth for transmission.
- The lowest in LAN, medium in MAN, and highest in WAN are the levels of data transmission mistakes and noise.
A local area network cannot cover cities and towns. Hence, a metropolitan area network is required to connect a city or a group of cities. A Wide area network is also necessary for joining a country or group of countries.
