1. What is a Wide Area Network (WAN)

A computer network is a collection of interconnected computers that share information. The term "network" can refer to either computer physical connections or conceptual interconnections between system components.

A wide area network (sometimes referred to as WAN) is a large network of computers that is not connected to a single place. Through a WAN provider, WANs permit communication, information sharing, and more between devices worldwide. Because the internet is the world's largest WAN, WANs are critical for multinational businesses and necessary for everyday use.

Service providers frequently build these networks and then hire them to businesses, schools, governments, and the public. Notwithstanding their position, these clients can utilize the network to transfer and keep data or communicate with other operators; so far, they have a connection to the established WAN. It is possible to grant connectivity through links, including wireless networks, virtual private networks, internet access, or cellular networks.

WANs enable international groups to execute their fundamental everyday activities without interruption. Workers worldwide can connect to a company's WAN to share information, communicate with coworkers, or stay connected to the company's data resource point. Qualified network professionals help companies maintain their internal WAN network and other critical IT infrastructure.

What is Wide Area Network (WAN) Used for

If WAN connectivity does not exist, establishments would be restricted to specific locations or geographic regions. Although LANs enable businesses to function within their own homes, increasing to other areas, such as different metropolises or even nations, would be impracticable since the required substructure would be extremely costly for many firms. As businesses expand and become increasingly global, WANs enable them to interact between offices, share information, and stay related. For example, WANs allow employees to access the information required to execute their jobs while on the road. Another use of a wide area network is to share information with clients and partners. In contrast, WANs provide an important service to the public. For example, university students can use WANs to view library databanks or do research. People use WANs daily to communicate, shop, bank, etc.

2. Pros and Cons of Wide Area Network (WAN)

A wide area network (WAN) is a communication network that spans a large geographical area and is typically used to connect computers. Towns, counties, and even countries can be connected through WANs. Larger firms or organizations usually employ WANs to enable data interchange, and corporations with several locations have incorporated WANs in various industries. On the other hand, small organizations are increasingly using WANs to expand their communication capabilities.

Pros of Using WAN:
  • Wide coverage: Generally, WAN covers a large geographical area. Assuming your company's offices are spread out throughout the country, WAN makes it easier to connect these offices effortlessly. Internet Service Providers (ISPs) can offer leased lines to achieve this purpose.

  • Centralized sharing of data: Using a wide area network (WAN) allows you to share data to all the devices on the network. For instance, you can establish a head office server and exchange data throughout the office locations. As a result, there is no need to buy separate files, emails, or backup servers. Alternatively, you can depend on the head office server for full backup and support.

  • Increased bandwidth: Corporate LAN normally uses lease lines to form a network backbone. With this, it means it provides more bandwidth than standard broadband connections. Therefore, using WAN in an organization helps increase bandwidth.

  • Quick delivery of messages: We have seen increased WAN-based devices with improvements in LAN and the Internet of Things (IoT). Because of this, communication is faster using popular applications like WhatsApp and messenger.

  • Guaranteed Uptime: Another significant advantage of WANs is consistent uptime. Nowadays, WAN providers offer assured uptime every time.

  • Global Market: Everyone with computer skills can start an internet business and grow it globally. Numerous companies provide stock sales, shopping carts, and selling.

Cons of Using WAN:
  • Costs of Installation: Due to their geographic coverage, WANs are sophisticated. As a result, they are costly to set up. Therefore, you must buy switches, routers, and security solutions to set up a WAN.

  • Maintenance Issues: Creating a WAN network is a full-time role that requires hiring high-tech network managers and specialists.

  • Requires Antivirus and Firewall Software: You must activate the firewall on the devices since data hackers can access and modify data transmitted through the internet. These hackers can install a virus on your machine. Therefore, it requires antivirus and firewall software for its safety.

  • Troubleshooting Issues: A WAN network covers large geographic areas, making it difficult to resolve an issue within the network.

  • Frequent Disconnection Problem: There might be inadequate energy supply for remote areas. Because of this, customers might experience disconnection issues frequently.

3. Differences Between LAN, MAN, and WAN

A wide area network (WAN) represents a computer network that links a group of computers over a large distance. For example, big businesses use WANs to connect their office networks, each with its LAN. The LAN is connected through a WAN. Normally, a WAN is a large network that spans a geographic location. For instance, the internet is a WAN.

An internet service provider owns a WAN, and users must subscribe or pay a fee to connect to remote areas. These service providers include satellite services, cable companies, or telephone networks. In addition, service providers offer links to interconnect remote websites to transport data, video, and voice.

On the other hand, a local area network (LAN) comprises a network confined to a small location. Small business and home Wi-Fi networks are typical examples of local area networks. Normally, anybody that manages the LAN is also responsible for the networking equipment. For instance, a small business will manage the switches and routers required to set a LAN up.

Computer networking is categorized into several types. This classification is based on their purpose and size. Network size is expressed in terms of the number of computers and geographic area. Four types of computer networks exist: LAN, MAN, WAN, and PAN (Personal Area Network). This section will examine the first three computer network types and their features. In addition, we will look at the different LAN and WAN computer network features.

3.1 LAN (Local Area Network)

A LAN represents a collection of peripheral and computer devices connected in a limited area, like a lab, home, or business property. A common network allows individuals to share resources such as games, printers, files, etc. LAN connects printers and computers in an office or home. LAN is utilized as one type of transmission medium. It is a network with less than 5000 connected devices spread throughout several buildings.

Features of LAN:

• No third party regulates it since it is a private network.

• LAN runs at a higher speed.

3.2 MAN (Metropolitan Area Network)

MAN is a computer network encompassing an entire city or a small area. This network is much larger than a LAN, which is usually restricted to a particular building or location. This type of network can cover a range of distances from a few miles to tens of miles, depending on the arrangement.

Features of MAN:

• Uses cables and optical fibers

• It covers a larger area (up to 50km)

• Data rates suitable for distributed computing applications

3.3 WAN (Wide Area Network)

A WAN, also known as a wide area network, is a telecommunications network that encompasses a large geographic area. The principal function of a wide-area network (WAN) is computer networking. The networks are interconnected so that they can interact with one another. The WAN is not limited to a particular location. It facilitates communication and information sharing among the links. In comparison to MAN and LAN, WAN is the largest network. A WAN can cover an entire country, continent, or globally. Broadband services, 3G, and 4G are examples of WAN.

Features of WAN:

• WAN is the largest network

• Many countries can link to WAN using a telecommunications network

• Connection is set up using satellites or telephone lines

4. How Does a Wide Area Network Work

WANs can be point-to-point, involving a straightforward link between two websites. It can also use a packet-switched, involving data being sent in packets through shared circuits. Analog dial-up lines, which employ a modem to connect a computer to a phone line, or specialized leased digital phone lines, sometimes known as "private lines." These are instances of a point-to-point wide-area network service.

Analog lines can be rented and ideal for group data transmissions like non-pressing order input and POS transactions. Devoted digital mobile lines provide continuous and secure data transmission at a regular cost.

Long-distance carriers and local telephone companies are mutually point-to-point WAN service providers. Therefore, establishments with limited amounts of records or sites for which several separated lines would be prohibitively expensive choose packet-switched network services.

Depending on the service, WANs are useful for every data exchange that LANs can be used for. On the other hand, slower transmission speeds may render some wide area network applications unrealistic. As a result, WANs are commonly used for e - mails and file transfers. In addition, WANs allow people on remote distance access and enter data into a central database, such as updating accounting records in real-time.

New network-based software, including groupware and workflow automation software that aid productivity and production tracking, can also be used via WANs. Workers in various places can collaborate on projects more readily with groupware. Remote offices can also use WANs to connect to centralized office data services like the internet.
