Packet switched
WAN. LAN is a short range connection, WAN is wide range.
A WAN is any technology used to connect networks at a greater distance. Without a WAN, your home - or in this case, your school - won't have a connection to the Internet.
I am pretty sure that a WAN connection would not be needed for a home network. A WAN is a Wide-Area Network. A WAN would be used to connect to your business computer from home. A LAN is a Local-Area Network. It should be sufficient if the network is simply for sharing files or printers, etc.
A wired WAN connection typically uses physical cables, such as fiber optics or copper, to connect users to the wide area network, providing stable and high-speed access. In contrast, a wireless WAN connection utilizes radio signals to connect devices to the network, offering flexibility and mobility but potentially less stability and speed compared to wired connections. Both types serve as access points for users to connect to the WAN, depending on the specific needs and infrastructure of the organization.
For a dedicated point-to-point WAN connection, a leased line is the most suitable option. Leased lines provide a consistent, secure, and high-speed connection directly between customer premises and the remote destination, ensuring reliable performance and low latency. This type of connection is ideal for businesses that require continuous and uninterrupted communication.
