The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is (b) A collection of interconnected computers and devices that can communicate and share resources<\/strong>.<\/p>\n\n\n\n A computer network refers to a system of interconnected devices that are capable of exchanging data and resources with one another. This includes computers, printers, servers, routers, switches, and other network-enabled devices. The primary purpose of a computer network is to enable communication between devices and facilitate the sharing of resources such as files, applications, or internet access.<\/p>\n\n\n\n There are different types of computer networks based on their size, scope, and the technology they use. For instance, a Local Area Network (LAN) is used to connect devices within a small geographical area, like a home or office. In contrast, a Wide Area Network (WAN) covers a larger geographic region, such as a city or country. The internet itself is a vast global network of interconnected devices, forming a type of WAN.<\/p>\n\n\n\n One of the key functions of computer networks is resource sharing. Devices on a network can share printers, storage devices, and other peripherals, which increases efficiency and reduces the need for redundant hardware. For instance, in an office setting, multiple computers can access a single printer connected to the network rather than each having its own printer.<\/p>\n\n\n\n Additionally, computer networks enable communication in various forms, including email, voice over IP (VoIP), and video conferencing. They use protocols such as Transmission Control Protocol\/Internet Protocol (TCP\/IP) to ensure that data is transmitted securely and reliably between devices.<\/p>\n\n\n\n Without networks, the modern internet-based communication and information sharing would not be possible. A computer network forms the backbone of many critical systems in business, education, healthcare, and entertainment.<\/p>\n","protected":false},"excerpt":{"rendered":" What is a computer network?
