computer network quiz part-1.
Computer networks serve as the backbone of modern communication, enabling the exchange of information and resources across interconnected devices. At its core, a computer network is a collection of computers and other devices linked together for the purpose of sharing data, resources, and services. These networks can range from small, local connections within a single building to vast global infrastructures connecting people and systems across continents.
One of the primary functions of computer networks is data transmission, where information is sent and received between devices. This transmission occurs through various mediums, including wired connections such as Ethernet cables and fiber optics, as well as wireless technologies like Wi-Fi and cellular networks. Network protocols govern how data is formatted, transmitted, and received, ensuring compatibility and reliable communication between different devices and systems.
Security is a critical aspect of computer networks, as they are susceptible to various threats such as unauthorized access, data breaches, and malware attacks. Network security measures, including firewalls, encryption, and intrusion detection systems, are implemented to safeguard against these threats and protect sensitive information.
