What is a network |
#youtube #youtubevideo #ccna
A network is a system of interconnected devices or nodes that communicate and share resources with each other. Networks can vary in scale from local area networks (LANs) within a single building to wide area networks (WANs) that span across cities, countries, or even globally. They enable the exchange of data and resources, enhancing communication, collaboration, and efficiency across multiple devices and users. Common types of networks include computer networks, social networks, and telecommunications networks. Key components of a network include hardware (such as routers, switches, and computers), software (such as operating systems and applications), and protocols that define how data is transmitted and received. Networks are essential for modern computing and play a crucial role in various aspects of everyday life, from internet connectivity to organizational operations.
