Managed LAN Services is a commercial facility that delivers occupied controlling of the LAN and WLAN setup at your small branch workplaces as well as your big estates and data centers. LAN means Local Area Network. Some networks are small and some are big. Some network only shares information among themselves and some are connected the world. In our daily life, we all are connected by some kind of network. Some are short some are long. LAN, MAN, and WAN are the main types. But there are also other types of network. These networks help us to communicate with each other and make our life much easier.
Wide area network
Wide area network shortly known as WAN is a combination of many short local area networks and metropolitan area network. So many LAN (Local area network) interconnected with each other and become a WAN. In that case, you can say that the Internet is the largest WAN. In simple words, WAN connects more than one LAN and used for a large geographic area. It helps us to connect with one other. Without WAN, It may be not possible to connect the whole world together. It is a combination of so many devices like routers, modems, firewalls and so on and used IP/TCP protocol. Its range is more than a 100-kilometer network.
Characteristics of WAN
- Cover a large geographical area: It can cover as much as area as you want.
- Unlimited expansion is possible: It has the capability for unlimited expansion.
Limitation of WAN
- Complex to implement: As it’s a large network, it’s quite difficult to implement.
- Security and reliability: Because it’s large network, there is a possibility of hacking our data.
- High implementation cost: The initial cost for WAN is very high.
- Complex administration: It’s quite difficult to maintain such a large network.
Metropolitan area network
Metropolitan area network is shortly known as MAN. More than one LAN is used to create a MAN. It is just like WAN but not as big as WAN. It is bigger than a LAN but smaller than a WAN. In short, it’s a medium range network. Like WAN it is not owned by any single men or organization. It can be a size of a network of a city or in some cases, some universities have their own MAN. But those are a shorter range. In some cases, you can consider is as a bank network. Like a Bank network, where there are different sections. You can consider the sections as LAN. And all the employee of the bank interconnected with each other and perform as a single network like MAM. It has a radius of 30-40 kilometers/20-25 miles.
What is the wan network
WAN is wide area network. More than one MAN or LAN merged with each other to form a WAN. Wi-Fi routers, modems, and other devices connect LAN to WAN. WAN cannot be owned by any men or organization. But different companies or telecommunication companies take a lease for their commercial purpose. The Internet can be considered as the largest WAN.
LAN meaning local area network. It is comparatively small. It may be limited to a single room or a building or maybe two or three building. LAN can be interconnected with each other by television or radio wave at any distance. So in these case, you can say distance doesn’t matter to connect a LAN.
Characteristics of LAN
- Easy to implement: In LAN, it’s very easy to implement. Only two computer and router a hub and a Cay5 cable needed to start a LAN.
- High-speed resources sharing: Can Share data at a very high speed.
- Low implementation cost: very low cost needed to start this network connection.
- Easy management: Easy to manage cause we have to manage a very limited area.
Limitation or LAN
- Cover only a limited area: It can cover only a limited geographical area.
LAN meaning Local area connection. When a group of computers and their related devices connected with each other called LAN. It is smaller than MAN or WAN. Multiple LAN interconnected and created a MAN. Each LAN can be connected through television network or radio wave at any distance. A LAN can be built with a cheap hardware such as Computers, Hubs, Ethernet cables etc. A Small LAN could be a connection between two computers. But larger LAN may be a combination of thousands of computers. LANs are used to share data among themselves but not for the outside world. For example, think of an office building where everyone’s computer is connected by LAN and they share information through the servers. LAN connection can be both wired and wireless. But the wireless connection is quite slow than the Ethernet cable connection. If a local area network is fully wireless then it could be called a wireless LAN in short WLAN. Its range can be around 1 kilometer or more.
LAN is local area network. It can be small or large. A small LAN maybe with a combination of two computers. But the large LAN could be a combination of thousands of computers. In this network, they shared their hard disk storages. In these case, the computers can share their information with each other. For example Cyber Café. In cyber café, hundreds of computer interconnected with each other with LAN.
Types of LAN
LAN can be two types:
Wire: The LAN which is fully Ethernet cable based is called the Cable based LAN. In these case, the Computers are connected with Cat5 cables. High-speed data transfer can be possible with cable-based LAN. Basically, in local area network, computers shared data with each other but does not make communication with outside world.
Wireless: The network which is fully wireless is called wireless LAN network. These networks are mainly slow. These are also called WLAN or wireless local area network.
WAN, MAN, SAN, LAN, VPN these are similar kind of network.
LAN means local area network. Local Area Network is small. When multiple computers connected with each other and share their information with each other, is called Local Area Network. Its range can be in a room or a building or more. For example: In school, college and homes people set local network according to their customers need.
So In this article, we see that common types of network and how they are interrelated.
