Computer Network Quiz Part-4.
Computer networks serve as the backbone of modern communication, facilitating the exchange of data and resources among interconnected devices worldwide. At their core, networks are composed of interconnected nodes, including computers, servers, routers, and switches, linked together through various mediums such as wired Ethernet cables, fiber optics, and wireless connections.
The primary function of a computer network is to enable communication and resource sharing. Through network protocols like the Transmission Control Protocol/Internet Protocol (TCP/IP), devices can transmit data packets across the network efficiently and reliably. This allows users to share files, access shared printers, communicate via email or messaging platforms, and collaborate on projects in real-time, regardless of their physical location.
Computer networks come in various sizes and types, ranging from small local area networks (LANs) within a single building or campus to expansive wide area networks (WANs) spanning across cities, countries, or even continents. LANs typically use Ethernet technology for high-speed data transmission within a limited geographic area, while WANs utilize technologies like leased lines, satellite links, and virtual private networks (VPNs) to connect geographically dispersed locations.
