The Most Common Types of Networks: LAN, WAN, VLAN, and WLAN

Definitions of LAN, WAN, VLAN, and WLAN:

Local Area Network (LAN): A network formed by computers or network devices communicating through either wired or wireless channels, characterized by close proximity.

Wide Area Network (WAN): A network created by connecting computers or network resources from various locations or local area networks, serving as an example of a publicly accessible WAN network.

Virtual Local Area Network (VLAN): Virtual local area networks established within an organization, emphasizing the creation of logically separate networks. This entails the logical separation of different IP networks and subnets within a network comprising devices connected to the same switch.

Wireless Local Area Network (WLAN): Data transmission within a wireless local area network occurs via radio waves, replacing traditional cabbles. This facilitates communication between wireless network devices such as smartphones, tablets, laptops and IoT devices with both LAN and the internet.
