A computer network is a system of interconnected devices, such as computers, servers, smartphones, and printers, that communicate to exchange data. They communicate using wired or wireless connections and can range from small home networks to the global Internet. In this video, we explore what a network is and how various types—such as LAN, WAN, and PAN—operate in our interconnected world.

Understanding the Context

You’ll discover the key components of a network, common... Meaning of network, from basic definitions to advanced concepts, including topology, network devices, advantages, and drawbacks, all explained comprehensively. In computer science, computer engineering, and telecommunications, a network is a group of communicating computers and peripherals known as hosts, which communicate data to other hosts via communication protocols, as facilitated by networking hardware. A network consists of nodes such as computers, servers, routers, and switches that send or receive data.

Key Insights

These nodes are connected through links, which may be wired (cables, optical fiber) or wireless (Wi-Fi, radio signals). Deploy wired and wireless devices, covering IP addressing, ports, protocols, and network architecture for network deployment. Understand documentation, life-cycle, change, and configuration management processes and procedures. This course covers the foundation of networking and network devices, media, and protocols. You will observe data flowing through a network and configure devices to connect to networks.
