Network connectivity is used to describe the link between 2 or more devices. Pretty much every computer, television, smart watch, printer, and mobile phone is connected to a network. The network could either be a Local Area Network (LAN), or a Wide Area Network (WAN). LAN connectivity is the connection between devices that does not include the internet, such as the connection your office computer has to a server. WAN connectivity is the connection your device has with other devices connected via the internet. All businesses rely on some sort of network connectivity these days.
