5 important points on networks: 1. Networks are made up of two or more computers and other devices connected together. 2. Networks allow devices to communicate with each other and share resources. 3. Networks can be wired or wireless. 4. Networks can be classified by their size and geographic scope, such as local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs). 5. Networks play an essential role in modern society, enabling businesses, governments, and individuals to communicate and collaborate effectively. 5 important points on each type of network: LANs: 1. LANs are typically limited in size to a single building or campus. 2. LANs use a variety of technologies to connect devices, such as Ethernet, Wi-Fi, and Bluetooth. 3. LANs offer high speeds and bandwidth, making them ideal for applications such as file sharing, streaming video, and gaming. 4. LANs are relatively easy to set up and manage. 5. LANs are widely used in businesses, schools, and homes. WANs: 1. WANs can span a city, country, or even the entire world. 2. WANs typically use long-distance communication technologies such as fibre optic cable and satellite links. 3. WANs offer lower speeds and bandwidth than LANs, but they can connect devices over long distances. 4. WANs are more complex to set up and manage than LANs. 5. WANs are used to connect LANs together, as well as to connect businesses, governments, and individuals to the Internet.
