Computer Networks

A Wide Area Network (WAN) covers a large geographical area, such as a country or continent, and often utilizes existing telecommunication infrastructure like telephone lines.

In a token ring network topology, a small frame called a token circulates around the ring. Only the computer that captures the token is allowed to transmit data, preventing collisions.

Servers are powerful computers designed to provide services, data, or resources to other computers, known as clients, over a network.

A router is a networking device that forwards data packets between computer networks, allowing multiple devices to share a single broadband Internet connection.

Network architecture refers to the overall design and structure of a computer network, including the physical components and the logical organization.

A multipoint line is a data communication link that connects more than two stations or nodes, allowing them to share the same transmission medium.

A computer network is defined as a collection of interconnected computing devices, such as computers, that can exchange data. While other devices can be part of a network, the fundamental definition centers on computers.

Modern computer networks are designed to handle various types of digital information, including data files, voice (VoIP), and video streaming. Therefore, they can exchange all of these types of content.

One of the primary benefits of networking is resource sharing, where expensive hardware like printers can be accessed by multiple users on the network. Books and CDs are physical media not typically shared via network protocols in this context.

Computer networks facilitate communication between people (via email, messaging) and between systems or databases (via API calls, data synchronization). Thus, both are correct.

Reliability is increased in computer networks because if one machine fails, the data or service can often be accessed from another machine on the network. This redundancy ensures that information remains available.

Computer networks allow users to access information stored on remote servers or computers, regardless of their physical location. This is a core function of modern networking.

Computer networks enable a wide range of online activities, including shopping, bill payment, and general web browsing. All these activities rely on network connectivity.

Based on transmission technology, computer networks are generally classified into two types: broadcast networks and point-to-point networks.
