Computer Networking Quiz Test: How Much Do You Know?

A client refers to any device or software application that is connected to a network and receives data from it. This can include computers, smartphones, tablets, or any other device that accesses the network to retrieve information or resources. Therefore, the statement "A client is any part of the network that receives data" is true.

A router in a network sends and receives data packets by looking at the destination.

A local-area network (LAN) is a network of computers and other devices that are confined to a relatively small space, such as a single building or a group of buildings. LANs are typically used in homes, offices, schools, and other small-scale environments where devices need to communicate and share resources with each other. Unlike global networks, which span large geographical areas, LANs are limited in scope and are designed for local communication and collaboration. Therefore, option 2, Local-Area Network, is the correct answer.

Option 1 is the correct answer because a hub is a small box with multiple connection points on the front or back. It is a networking device that allows multiple devices to connect to a network and share data. Hubs are commonly used in Ethernet networks to connect computers, printers, and other devices together. They receive data packets from one device and then broadcast them to all other devices connected to the hub.

A network device that has multiple ports to connect multiple computers is a switch/hub. A switch or hub acts as a central connection point for multiple devices in a network. It allows multiple computers to connect and communicate with each other by forwarding data packets between the connected devices. This device is commonly used in local area networks (LANs) to create a network infrastructure that enables efficient data transmission and sharing among connected devices.

The correct answer is option D because a computer network is a collection of computers and devices that are interconnected by communication channels for the purpose of communication and sharing of resources and information.

A server refers to any combination of hardware or software that is specifically designed to provide services to clients. This can include various types of servers such as web servers, file servers, email servers, etc. The server is responsible for receiving and processing requests from clients and delivering the requested data or services. It acts as the central hub in a network, facilitating communication and data sharing between clients.

WAN (Wide Area Network) has the widest coverage among the given options. A WAN is a network that covers a large geographical area, such as multiple cities or even countries, and connects multiple LANs (Local Area Networks) together. MAN (Metropolitan Area Network) covers a smaller area than a WAN, typically within a city or metropolitan area. LAN (Local Area Network) covers the smallest area, usually within a single building or campus. eWAN is not a commonly used term in networking, so it is not a valid option.

A modem is a device that is used to connect to the internet using a telephone line. It converts digital signals from a computer into analog signals that can be transmitted over a telephone line, and vice versa. This allows for the transmission of data over the telephone network, enabling internet connectivity. Switches, routers, and hubs are not specifically designed for connecting to the internet using a telephone line.

Protocol refers to a set of rules that govern the communication between network computers. It defines the format, timing, sequencing, and error control of data transmission. By following these rules, network computers can effectively communicate with each other.

A network topology in which all data/information pass through a central device is the star topology. In this topology, all devices are connected to a central device (such as a switch or hub) and communicate through it. This central device controls the flow of data and acts as a central point of control for the network.

The correct answer is C. Server. A server is a part of computer network infrastructure that interconnects various pieces of the network, providing a path for the exchange of information between different LANs or subnetworks. Servers are responsible for managing network resources, such as files, printers, and databases, and they facilitate communication and data exchange between different devices on the network.

The most commonly used local area network topology is the star topology. In a star topology, all devices are connected to a central hub or switch, which acts as a central point of communication. This topology is widely used because it offers high reliability, easy scalability, and better performance compared to other topologies. Additionally, it allows for easy troubleshooting and isolation of network issues.

A Network Interface Card (NIC) is a hardware component that connects a computer to a network by providing a physical interface between the computer and the network wiring. It allows the computer to send and receive data over the network. Therefore, the statement "Card connects each computer to the wiring in the network" accurately describes the function of a Network Interface Card.

TIA stands for Telecommunications Industry Association.

A peer-to-peer network is easier to set up compared to a client/server network. This is because in a peer-to-peer network, there is no need for a central server, which reduces the complexity of the network setup. Each node in a peer-to-peer network can act as both a client and a server, allowing for direct communication and file sharing between nodes without the need for a dedicated server. This simplicity in setup makes peer-to-peer networks more convenient and accessible for smaller environments or home networks.
