Topology refers to the shape of Network.

True
False

Correct Answer

A. True

Explanation

Topology refers to the shape or structure of a network, including how the devices are connected and the arrangement of those connections. It describes the physical and logical layout of the network, such as whether it is a star, ring, bus, or mesh topology. Therefore, the statement "Topology refers to the shape of Network" is true.

Which of the following are Network topologies?

Line
Bus
Tree
Hub
Ring
Star
Loop

Correct Answer(s)

A. Bus
A. Tree
A. Ring
A. Star

Explanation

The given options, Bus, Tree, Ring, and Star, are all examples of network topologies. A network topology refers to the arrangement or structure of a computer network, including how devices are connected and the paths through which data flows. In a Bus topology, all devices are connected to a single cable, while in a Tree topology, devices are connected in a hierarchical structure. A Ring topology forms a closed loop, with each device connected to the next, and a Star topology has all devices connected to a central hub. Therefore, these options correctly represent different network topologies.

LAN stands for Local Area Network

True
False

Correct Answer

A. True

Explanation

LAN stands for Local Area Network, which is a network that connects devices within a limited area such as a home, office, or building. It allows for the sharing of resources, such as printers and files, and enables communication between devices connected to the network. Therefore, the given answer "True" is correct as it accurately defines the acronym LAN.

LANs are not based in the same building.

True
False

Correct Answer

A. False

Explanation

LANs are based in the same building. This means that Local Area Networks (LANs) are typically confined to a single building or a small area, such as an office, school, or home. They allow devices within the same building to connect and communicate with each other, sharing resources like printers, files, and internet access. Therefore, the given statement is false because LANs are indeed based in the same building.

WAN stands for Wireless Area Network

True
False

Correct Answer

A. False

Explanation

The given statement is incorrect. WAN stands for Wide Area Network, not Wireless Area Network. A Wide Area Network is a network that spans a large geographical area, connecting multiple local area networks (LANs) together. It is typically used to connect computers and devices across different cities or even countries.

The Internet is a LAN.

True
False

Correct Answer

A. False

Explanation

The statement "The Internet is a LAN" is false. LAN stands for Local Area Network, which refers to a network that is limited to a small geographical area, such as a home, office, or building. On the other hand, the Internet is a global network that connects computers and networks all over the world. It is not limited to a specific geographical area, making it much larger in scale than a LAN. Therefore, the Internet cannot be considered a LAN.

In wired networks, are used.

Correct Answer
cables

Explanation
In wired networks, cables are used to establish physical connections between devices. These cables carry electrical signals and data between devices, allowing for communication and data transfer. Without cables, it would not be possible to establish a physical connection between devices in a wired network. Therefore, cables are an essential component of wired networks.

In wireless networks, devices communicate via .

Correct Answer
Radio waves

Explanation
In wireless networks, devices communicate via radio waves. Radio waves are electromagnetic waves that are used to transmit and receive signals wirelessly. These waves have a long wavelength and low frequency, allowing them to travel long distances without much attenuation. Devices such as smartphones, laptops, and routers use radio waves to establish wireless connections and exchange data. The use of radio waves in wireless communication allows for convenient and flexible connectivity, enabling devices to communicate without the need for physical connections.

Protocol is a standard of communication between computers.

True
False

Correct Answer

A. True

Explanation

The statement is true because a protocol is indeed a standard or set of rules that governs communication between computers. It ensures that different devices and systems can understand and interact with each other effectively. Protocols define the format, timing, sequencing, and error control of data transmission, enabling successful communication and data exchange between computers.
