Computers communicate through networks from "summary" of Computer Networking Beginners Guide by Russell Scott
Communication between computers is made possible through networks. A network is essentially a collection of devices connected together to share information and resources. These devices can include computers, servers, printers, and other electronic devices. By establishing a network, these devices can communicate with each other, allowing for the sharing of data, files, and even hardware resources. There are different types of networks that computers can utilize to communicate with each other. Local Area Networks (LANs) are networks that are confined to a small geographical area, such as a home, office, or school. This type of network allows for devices within the same location to easily communicate with each other. On the other hand, Wide Area Networks (WANs) span larger geographical areas and can connect devices across different cities, countries, or even continents. WANs often utilize the Internet to connect devices and enable communication between them. Networks can also be classified based on their connection methods. Wired networks use physical cables to connect devices, while wireless networks use radio waves to establish connections between devices. Both types of networks have their own advantages and disadvantages, depending on factors such as speed, security, and convenience. In order for computers to communicate through networks, they must follow a set of rules and protocols. Protocols are essentially a set of guidelines that dictate how data is transmitted and received between devices on a network. By adhering to these protocols, devices can ensure that data is sent and received accurately and efficiently.- The concept of computers communicating through networks is essential in today's interconnected world. By establishing networks, devices can easily share information and resources, leading to increased productivity and efficiency in various fields. Understanding how networks function and how devices communicate with each other is crucial for anyone looking to work in the field of computer networking.
