What is a network?

Brief Summary

This video provides a concise overview of computer networks, explaining their basic components, types, and relevance to council operations. It differentiates between public and private networks, using examples like intranets and the internet. The video encourages viewers to engage with their IT departments for further learning and to consider network optimisation and security.

• Defines what a network is and its components (servers and clients).
• Explains the difference between public and private networks.
• Highlights the relevance of networks in council operations.

What is a Network?

The video defines a network as two or more computers connected to share information or resources. More broadly, a network is the interconnection of computing devices, including computers, phones, printers, and smart devices. As a councillor or officer, you'll encounter networks in operational tasks like connecting to internal council systems and in public-facing functions such as providing Wi-Fi in a public library.

Network Components: Servers and Clients

Networks typically consist of servers and clients. User devices, or clients, communicate with centrally located servers to access resources. A server is a high-capacity computer that houses hard drives, printers, and other resources shared across the network. Servers are designed to handle more intensive workloads than personal computers. Clients are the computers and devices on the network that request and receive resources from servers, such as end-user devices like phones and personal computers.

Public vs. Private Networks

The video outlines two main types of networks: public and private. A private network restricts unauthorised users from joining. An intranet, a network connecting devices within a specific setting, is an example of a private network. The internet, a global network of networks enabling worldwide information sharing, is a public network due to its accessibility.

Further Learning and Network Optimisation

To learn more about networks, viewers are encouraged to consult with their IT departments and ask questions about network optimisation and security. The video is part of a series aimed at expanding understanding of digital technology and cyber security concepts, with viewers encouraged to explore other videos in the series.
