Mrs Telfer's Introduction To Networks

2.

Which of the following define the purpose of networks?

Facilitating communications.
Sharing hardware
Sharing files, data, and information
Sharing software
Catching electric fish

Correct Answer(s)

A. Facilitating communications.
A. Sharing hardware
A. Sharing files, data, and information
A. Sharing software

Explanation

The purpose of networks is to facilitate communication between devices, allowing them to share hardware resources, files, data, and information. Networks enable devices to connect and interact with each other, enabling efficient communication and collaboration. Sharing software is also a purpose of networks, as it allows multiple devices to access and use the same software applications or programs.

Which of the following are classifications of networks?

Wired technologies
Functional relationship (network architecture)
Connection method
Wireless technologies
Network topology

Correct Answer(s)

A. Wired technologies
A. Functional relationship (network architecture)
A. Connection method
A. Wireless technologies
A. Network topology

Explanation

The classifications of networks include wired technologies, functional relationship (network architecture), connection method, wireless technologies, and network topology. Wired technologies refer to networks that use physical cables to transmit data, while wireless technologies use wireless signals. Functional relationship (network architecture) refers to the way network devices are organized and connected. Connection method refers to the way devices are connected to the network, such as Ethernet or Wi-Fi. Network topology refers to the physical or logical layout of the network, such as star, bus, or mesh.

Twisted pair wire is the least widely used medium for telecommunication.

True
False

Correct Answer

A. False

Explanation

Twisted pair wire is actually one of the most widely used mediums for telecommunication. It is commonly used for telephone lines and local area networks (LANs). It consists of two insulated copper wires twisted together to reduce interference and crosstalk. Twisted pair wire is cost-effective, easy to install, and provides reliable communication over short to medium distances. Therefore, the given statement is false.

Coaxial cable is widely used for cable television systems, office buildings, and other worksites for local area networks

True
False

Correct Answer

A. True

Explanation

Coaxial cable is indeed widely used for cable television systems, office buildings, and local area networks. It is a type of cable that consists of a central conductor, surrounded by an insulating layer, a metallic shield, and an outer insulating layer. This design allows for efficient transmission of high-frequency signals with minimal interference. Due to its superior performance in carrying television and data signals over long distances, coaxial cable has become the preferred choice for these applications. Therefore, the statement is true.

Fiber-optic cables are affected by electromagnetic radiation.

True
False

Correct Answer

A. False

Explanation

Fiber-optic cables are not affected by electromagnetic radiation. Unlike copper cables, which can experience interference from electromagnetic radiation, fiber-optic cables use light signals to transmit data. This means that they are immune to electromagnetic interference and provide a more reliable and secure transmission of information.

"Using a network, people can communicate efficiently and easily via e-mail, instant messaging, chat rooms, telephone, video telephone calls, and video conferencing" is also known as

Sharing hardware.
Sharing files, data, and information
Facilitating communications
Sharing software

Correct Answer

A. Facilitating communications

Explanation

The given statement describes how people can communicate efficiently and easily using various methods such as email, instant messaging, chat rooms, telephone, video telephone calls, and video conferencing. This process of enabling and making communication easier is known as facilitating communications.

Choose all the network connection methods listed.

Ethernet
Bnp.01
Optical fiber
Ultranet
Gopherline communication

Correct Answer(s)

A. Ethernet
A. Optical fiber

Explanation

The correct answer is ethernet and optical fiber. Ethernet is a widely used network connection method that allows devices to connect and communicate with each other over a local area network (LAN). Optical fiber, on the other hand, is a high-speed transmission medium that uses thin strands of glass or plastic to transmit data as pulses of light. It is known for its high bandwidth and long-distance capabilities, making it ideal for long-haul communication networks. Both ethernet and optical fiber are commonly used in modern networking to provide reliable and fast connections.
