If you’re new to networking technology, you may feel like dipping your spoon into a bowl of alphabet soup. LAN, WAN, VPN – What do they all mean? This article will help you type out all of those terms. Fortunately, once you learn what the terms mean, it’s simple to comprehend how they work. The critical difference is the geographical areas they serve.

What’s a Local Area Network (LAN)?

Local area networks are created to provide networking services to a group of computers that can be close to one another. A Local Area Network can work on a single floor in an office building or a classroom in a school. LAN is the standard set up as a single subnet with a clearly defined mask. LANs can be created based on wired or wireless connections. The size of a presented LAN can vary from one room to one building or even to a group of buildings, depending on the users’ wants. When utilizing IP/TCP networking, wireless is most commonly used because of its convenience and ease.

What’s a Wide Area Network (WAN)?

WAN connects computers over large physical distances, such as the entire country or world. They’re remotely related over a massive network and are allowed to communicate irrespective of their space. The internet is usually a public WAN that connects computers all around the world together. Many multiple small networks, like LAN or MAN, are related to making a WAN. WAN is so large that one administrator can’t control the whole network, so usually, there are multiple administrators.

What’s a Virtual Private Network (VPN)?

A virtual Private Network (VPN) is a type of computer network which doesn’t have physical existence. The devices which can be part of a VPN could be present wherever on the earth, connected over the internet. VPN is utilized by corporates to interconnect their offices located in another place and gives their remote employees access to the company’s resources. It has phased out another kind of network called an Enterprise Private Network, a physical network produced by organizations to link their office locations. If you want to protect your IP, then VPN is the best option for anyone to protect the data.

Over the WAN, VPNs allow the creation of voice and data networks that mix the benefits of both public services and private facilities. With these services and features defined in software and implemented through out-of-band signaling methods, users have greater flexibility in configuring their networks from on-premises terminals and management systems. With the VPN, businesses can save significantly over regular dial-1 rates on calls between on-net locations, including calls placed by mobile employees using the VPN phone card. With custom-dialing plans, corporate employees can merely dial extensions to place long-distance calls. With accounting codes, telecom managers can easily track costs and chargeback users. At that point, you should be familiar with some fundamental networking terminology and be able to understand how different elements can communicate with each other.
