Wan (wide area network) is a telecommunications term that refers to a computer network that spans a large geographical area. A wan can be used to connect multiple local area networks (LANs) together, or it can be used to connect a LAN to the internet.
There are two main types of wan connections: leased line and broadband. Leased line is a type of wan connection that provides a dedicated, always-on connection between two or more devices. This type of connection is typically used by businesses that need to send large amounts of data between locations.
Broadband is a type of wan connection that uses a shared network infrastructure, such as the internet, to connect multiple devices. This type of connection is typically used by home and small business users.

What is the purpose of WAN?
What is the purpose of WAN?
A wide area network, or WAN, connects two or more geographically dispersed LANs, creating a single integrated network. A WAN can be used to connect different organizations, such as businesses, schools, or government agencies, or it can connect different parts of the same organization.
A WAN typically uses a telecommunications provider, such as a telephone company, to provide the necessary networking hardware and services. This can include, for example, leased lines, routers, and switches.
There are a variety of reasons to use a WAN. One common reason is to create a single network that can be used by multiple organizations. This can save money and simplify management, since each organization only has to deal with a single network rather than multiple networks.
A WAN can also be used to extend the reach of a LAN. For example, if a company has a branch office in a remote location, the branch office can be connected to the company’s main office via a WAN. This allows the employees at the branch office to access the same resources as employees at the main office.
A WAN can also be used to connect different parts of the same organization. For example, a company might use a WAN to connect its headquarters with its data centers. This allows the company to centrally manage its network and data storage.
Finally, a WAN can be used for disaster recovery. If the headquarters of a company are destroyed in a fire, for example, the company can use a WAN to connect its branch offices and continue to operate.

What is a WAN example?
A Wide Area Network (WAN) connects two or more LANs, typically over a large distance. A WAN example might be a company that has several branch offices spread out over a large geographical area. In order to allow employees at different locations to share resources and communicate with each other, the company would need to set up a WAN.
There are several different types of WANs, but the three most common are circuit-switched, packet-switched, and leased line.
Circuit-switched WANs use dedicated physical circuits between the two locations. These circuits are always up and running, and they provide a constant bandwidth for transferring data.
Packet-switched WANs use packet-switching technology to share a single physical circuit among several users. This allows the circuit to be used more efficiently, and it also allows users to share the cost of the circuit. However, packet-switched WANs can be less reliable than circuit-switched WANs.
Leased line WANs use dedicated, point-to-point connections between two locations. Leased lines offer the highest bandwidth and the most reliability, but they are also the most expensive.
Does WAN mean Internet?
The term WAN is often used interchangeably with the term “Internet,” but this is not strictly accurate. The WAN, or wide area network, is a term used to describe a network that covers a large geographical area, such as a city, state, or country. The Internet, on the other hand, is a global network that connects computers all over the world.
That said, the WAN and the Internet are related in that the WAN is one of the components that make up the Internet. Other components include the Local Area Network (LAN), which connects computers within a small area, such as a building or campus, and the Wide Area Network, which connects LANs together over a large area.
What is difference between a LAN and a WAN?
A LAN is a Local Area Network while a WAN is a Wide Area Network. LANs are typically confined to a single building or campus, while WANs can connect different LANs together over a larger area.
WANs can be used to connect different LANs together over a larger area, or to connect a company’s offices together. A WAN can also be used to connect a company to the internet.
LANs are typically faster and more reliable than WANs, because the data is travelling over a shorter distance. WANs are also more susceptible to network congestion and outages.
How do I connect to a WAN network?
A WAN, or wide area network, is a network that spans a large geographic area. In order to connect to a WAN, you’ll need to have a WAN connection. This can be a cable connection, a DSL connection, or a satellite connection.
Once you have a WAN connection, you’ll need to set up your network settings. In most cases, you’ll need to enter your WAN IP address, your WAN subnet mask, and your WAN gateway address. You may also need to enter your WAN DNS server address.
If you’re not sure how to set up your network settings, consult your network administrator or your network device’s user manual.
How computers are connected in WAN?
In the early days of computing, all devices were connected to a central hub, similar to the way phones are connected in a telephone network. This central hub was known as a mainframe, and it was responsible for handling all the traffic between devices.
As technology evolved, we started to see the emergence of personal computers. These devices could not connect to the mainframe directly, so we needed a new way to connect them. This is where the Wide Area Network (WAN) comes in.
A WAN is a network that spans a large area, usually covering multiple cities or countries. It connects multiple devices together, allowing them to share data and communicate with each other.
The most common type of WAN is the internet, which connects devices all over the world. Other common WANs include corporate networks and telecommunication networks.
To connect to a WAN, you need a special device called a router. The router acts as a gateway, connecting your device to the WAN and allowing you to access the internet.
Most routers come with a built-in firewall, which helps protect your device from malicious traffic. They also typically include a range of features such as Wi-Fi and VPN support, which allow you to connect to the network remotely.
So, how do computers connect in a WAN? Well, it all starts with the router, which acts as the gateway to the network. The router connects to the WAN, and then your device connects to the router. From there, you can access the internet and all the resources it has to offer.
Who might use a WAN?
A Wide Area Network (WAN) is a telecommunications network that covers a large geographical area. A WAN can be used by businesses to connect multiple sites together, or by individuals to connect to the internet.
Businesses might use a WAN to connect multiple sites together. This can be useful for businesses that have multiple offices, or that need to share resources between sites. A WAN can also be used to connect a business to its customers or suppliers.
Individuals might use a WAN to connect to the internet. A WAN can be used to get around restrictions on internet access, such as censorship or geographical location. A WAN can also be used to get faster internet speeds than are available in the individual’s location.
