Bus network. A bus network follows the LAN topology, where devices in a single LAN are attached directly to a transmission line known as a bus. All signals pass through all devices, and the recipient device recognizes the signals intended for it.
The devices can also communicate with each other without having to establish a direct connection to each device. For example, you can send a print job to a Wi-Fi-enabled printer without first connecting the printer to the computer using a cable.
Protocol: A protocol is a set of rules and standards that govern how data is transmitted over a network. Examples of protocols include TCP/IP, HTTP, and FTP.

Virtual private networks (VPNs). A VPN extends a private network over a public network to improve the privacy and security of a network connection.
Understanding the basics of computer networking is essential in today’s interconnected world. Networks enable the seamless exchange of information, support countless applications, and underpin the functionality of the Net.
Computer networks can also include multiple devices/mediums which help in the communication between two different devices; these are known as Network devices and include things such as routers, switches, hubs, and bridges.
