WAN (Wide Area Network):
Wide area network (WAN) works the same way as LAN does but is ultimately a larger network overall. By larger it means the network covers more than just one area such as a residential home like LAN, and rather has the size of more than one location. However, as networking in general improves over the years, WAN has expanded to spread beyond to crossing countries and continents, which have becoming international. An example would be many different users from around different countries or the world can connect to a wider area of a network and share information to each other such as employees working in the same company but different branches (see figure 1). Moreover, different examples of WAN include the internet and satellite links.

LAN (Local Area Network):
A local area network (LAN) is essentially a WAN but covers a smaller
range of area as defined by its geographical reach, often limited and used
usually by a small building such as a house, college, and a store etc. This is
because businesses and systems can be more secure if only a small amount of
people who access it there uses the devices and information/data they share,
which means it is unnecessary to have a larger network, (see figure 3). As LANs
are usually only located to one site of a network, it can also connect to other
LANs to form a WAN as a result, (see figure 2). Despite the limited area of
reach it provides, it is used by a lot of individual groups because it is much
faster for transferring data due to its closeness.

Wireless:
Wireless is a piece of communication device (such as a wireless router) which allows connectivity for all types of wireless devices, (see figure 4). An example includes smartphones and laptops as it transmits and receives data consistently without the need of cables by using radio waves. Furthermore, wireless network are used because it is more low-priced than having to purchase cables such as Ethernet, making it cost-effective for businesses or larger organisations. Usually, all devices without a cable should have a wireless adapter that connects to the Wi-Fi – the signal between the router and the device itself.
