Which one connects two similar network segments?

A. Router
B. Bridge
C. Gateway
D. Node

Answer

Correct Answer: B. Bridge

Detail about MCQs

A bridge is a network device that connects two similar network segments at the data link layer of the OSI model. It operates by examining the destination address of data packets and making decisions about whether to forward them or not. Bridges are used to divide large networks into smaller segments to improve overall performance and efficiency. They help manage traffic and reduce collision domains within a network, enhancing network stability and reliability

The network in which we connect each node to the network along a single piece of network cable is called?

A. Bus Network Topology
B. Ring Network Topology
C. Star Network Topology
D. None of these

Answer

Correct Answer: A. Bus Network Topology

Detail about MCQs

In a bus network topology, all nodes are connected to a single continuous cable, known as the “bus.” Each node communicates with others by transmitting data onto the bus. This topology is relatively simple and inexpensive to set up but can suffer from performance issues as more nodes are added or if the cable is damaged, as it can disrupt communication for the entire network segment.

Terminal that does not process or store data but serves as an input/output devices for an attached or network linked processor is called:

A. Intelligent Terminal
B. Super Terminal
C. Low Terminal
D. Dumb Terminal

Answer

Correct Answer: D. Dumb Terminal

Detail about MCQs

A terminal that does not process or store data but serves as an input/output device for an attached or network-linked processor is commonly referred to as a “Dumb Terminal.” These terminals rely entirely on the processing power and storage capabilities of the connected or network-linked computer or server.

Which of the following is a type of computer virus that is designed to spread from computer to computer over a network?

A. Trojan Horse
B. Worm
C. Spyware
D. Adware

Answer

Correct Answer: B. Worm

Detail about MCQs

Worm is a type of computer virus that is designed to spread from computer to computer over a network. Worms are self-replicating malware that can exploit vulnerabilities in computer systems and networks to propagate themselves. They don’t require user intervention to spread and can automatically send copies of themselves to other devices connected to the same network. Once a worm infects a system, it can consume network resources, degrade performance, and carry out malicious activities, such as installing backdoors or stealing sensitive information.

Which of the following is a type of computer network that covers a large geographic area, such as a country?

A. Local Area Network (LAN)
B. Wide Area Network (WAN)
C. Metropolitan Area Network(MAN)
D. Personal Area Network (PAN)

Answer

Correct Answer: B. Wide Area Network (WAN)

Detail about MCQs

Wide Area Network (WAN) is a type of computer network that covers a large geographic area, such as a country. WANs are used to connect devices and networks over long distances, often using public or private telecommunication networks. They enable communication and data transfer between different locations, allowing organizations to connect their branches or offices spread across a wide area. WANs utilize various technologies, such as leased lines, satellite links, and internet connections, to establish connectivity over vast distances. Local Area Network (LAN) is a network that covers a small area, like an office building or a home. Metropolitan Area Network (MAN) is a network that spans a city or metropolitan area. Personal Area Network (PAN) is a network that connects devices within the immediate vicinity of an individual, typically within a range of a few meters.
