1. What is a computer network? |
|
Ans. A computer network is a collection of interconnected devices, such as computers, servers, routers, and switches, that are connected together to share resources and communicate with each other.
2. What are the benefits of using a computer network? |
|
Ans. There are several benefits of using a computer network. It allows for the sharing of resources, such as printers and files, which can help improve efficiency and productivity. It also enables communication and collaboration among users, facilitates data backup and recovery, and provides access to the internet.
3. What are the different types of computer networks? |
|
Ans. There are several types of computer networks, including local area networks (LANs), wide area networks (WANs), metropolitan area networks (MANs), and personal area networks (PANs). LANs are used to connect devices within a limited area, such as a home or office, while WANs connect devices over a larger geographical area. MANs are used to connect devices within a city or metropolitan area, and PANs are used for personal devices, such as smartphones and laptops.
4. What is a protocol in computer networks? |
|
Ans. In computer networks, a protocol is a set of rules and guidelines that govern the communication between devices. It defines how data is transmitted, received, and interpreted, ensuring that devices can understand and communicate with each other effectively. Examples of network protocols include TCP/IP, HTTP, and FTP.
5. What are the main components of a computer network? |
|
Ans. The main components of a computer network include devices, such as computers, servers, routers, switches, and modems, which are connected together using cables or wireless connections. Additionally, network software, such as operating systems, protocols, and applications, is required to facilitate communication and resource sharing. Finally, network infrastructure, such as cables, switches, and routers, is needed to physically connect and manage the network.
