What Is Network A MAN is a series of local area networks that connect cities and can also connect to wide area networks. The internetwork is often used to describe the construction of large wide area networks. A network is defined as a group of two or more computer systems linked together.
What Is Network
A computer network is a cluster of computers on a common communication channel that works to share resources from one computer to another, provided or located on network nodes.
A computer network consists of two or more computers connected by cables (wired) or Wi-Fi (wireless) for the purpose of transferring, exchanging or sharing data and resources. Computer network nodes may include personal computers, servers, network equipment, or other specialized or general hosts. Network types are different from network topologies (such as bus, ring, and star).
Type Of Network
So, in this blog, we will learn about the different types of computer networks depending on the geographic areas they cover, functionality, properties, and media used.
A campus network (CAN) is a computer network that connects specific local area networks (LANs) on a campus or campus corporate network.
The campus network can connect various campus buildings. A campus network is larger than a local area network but smaller than a metropolitan area network (MAN) or wide area network (WAN).
MAN (Metropolitan Area Network) –
a metropolitan area network is a computer network that connects users to computer resources in a geographic area or region wider than the area covered by a large local area network (LAN), but smaller than the area covered by a wide area network . (VAN).
Wireless Local Area Network (WLAN) –
A wireless local area network (WLAN) is a wireless computer network that connects two or more devices wirelessly in a limited area such as a home, school, computer lab, or office building. This gives users the ability to move within their local coverage area and still remain connected to the network. This type of network connects to users through access points scattered over a wide area.
As dedicated high-speed networks that connect the shared storage pool to different servers, these types of networks are not LAN or WAN dependent.
SAN (Storage Area Network or System Area Network) –
For a SAN as a dedicated high-speed network that connects a pool of shared storage devices to multiple servers, these types of networks do not depend on a local area network or wide area network. An example of a SAN is a network of disks accessed from a network of servers.
Local Area Network
Network Type Characteristics of a Local Area Network (LAN) A Local Area Network (LAN) is a computer network that connects computers within a limited area such as a home, school, laboratory, campus, or office building  Virtual Local Area Network (VLAN) ) VLAN is a group of devices on one or more LANs configured to communicate as if they were connected to the same wire, when in fact they are on several different LAN segments.
LANs connect computers and peripherals in a limited physical area, such as a commercial office, laboratory, or campus, using communication channels (cables, Ethernet cables, fiber optics, Wi-Fi) that transfer data quickly. A LAN is used to connect computers and other network devices so that the devices can communicate with each other to share resources.
Examples of local area networks are networks in a home, school, library, laboratory, college, office, etc. A WAN system may be a local area network connection that connects to other local area networks using telephone lines and radio waves.
This can be a standalone network, such as a cable TV network, or a means of connecting multiple LANs to a larger network so that resources can be shared from one LAN to another and from one device to another.
A MAN is larger than a LAN but smaller than a WAN, and it contains elements of both types of networks. A MAN network covers a large area, connecting a local area network to a larger computer network. In a MAN, several local networks are connected to each other via telephone exchange lines.
In other words, a local area network connects a relatively small number of machines in a relatively close geographical area. Conceptually, a PAN (personal area network) and a wireless LAN (local area network) differ in that the former is usually centered around a personal network, while the latter is a wireless local area network (LAN) serving multiple users. A PAN is the smallest and simplest type of network, consisting of a wireless modem, one or two computers, phones, printers, tablets, etc., and revolves around people in a building.
These types of networks are created and owned by companies that want to securely connect different locations to share computer resources. These types of networks, which are typically used in the same types of applications as LANs, do not require devices to rely on physical cables to connect to the network. This type of network can be used to connect devices in a building or even in 2-3 buildings depending on their proximity to each other.
Depending on the type of configuration, this type of network can cover an area from a few miles to tens of miles. It offers fast communication using high speed media such as fiber optic cables. It is generally used to connect two or more personal computers using communication media such as coaxial cables, twisted pairs, etc.
The simplest type of LAN is to connect a computer and printer to someone’s home or office. For example, the library will have a wired or wireless local area network so that users can connect local network devices, such as printers and servers, to connect to the Internet. Other examples of WANs are mobile broadband connections such as 3G, 4G, etc.
WANs connect small computers and networks to larger networks in larger regions, including several continents. WANs do the same thing as LANs, but they take up more space because they connect more devices. WANs typically use technologies such as ATM, Frame Relay, and X.25 to communicate over long distances.
Homes typically use a local area network and use a broadband modem to connect to the global Internet through an Internet Service Provider (ISP). The ISP provides the modem with a WAN IP address, and all computers on the home network use a LAN IP address (also known as a private IP address).
All computers on a home LAN can communicate directly with each other, but must go through a central network gateway, usually a broadband router, to reach the ISP and beyond. A WLAN is simply a local area network that does not use cables to connect to the network.
A home network is designed to integrate devices such as printers, computers, TVs, but is not connected to the Internet.
Internetwork An Internetwork is defined as two or more computer LANs or WANs or segments of a computer network connected through devices and configured in a local addressing scheme.
An internetwork is the connection of several different types of computer networks into a single computer network by overlaying various network software and connecting them together through routers.
