In this topology, each node is connected with the help of a single co‐axial cable.
- A.
Star
- B.
Bus
- C.
Ring
- D.
Mesh
Correct Answer
B. BusExplanation
In a bus topology, all nodes are connected to a single co-axial cable, creating a linear network. Each node receives all the data transmitted on the cable, but only the intended recipient processes it. This topology is cost-effective as it requires less cable and is easy to install. However, if the main cable fails, the entire network can be affected.Rate this question:

A device that converts data from digital bit stream into an analog signal and vice versa.
- A.
Switch
- B.
Modem
- C.
Router
- D.
Hub
Correct Answer
B. ModemExplanation
A modem is a device that converts data from a digital bit stream into an analog signal and vice versa. It allows digital devices, such as computers, to connect to an analog network, such as a telephone line. The modem modulates the digital data into analog signals for transmission over the network and demodulates the analog signals back into digital data for the receiving device. This enables communication between digital devices and analog networks, making it an essential component for connecting to the internet through a telephone line.Rate this question:

- A.
Repeater
- B.
Modem
- C.
Gateway
- D.
Hub
Correct Answer
A. RepeaterExplanation
A repeater is a network device that amplifies or regenerates a signal over the same network.

Amit needs a network device to connect two different networks together that work upon different networking models so that the two networks can communicate properly.
- A.
Bridge
- B.
Gateway
- C.
Modem
- D.
Hub
Correct Answer

Which type of network is formed, when you connect two mobiles using Bluetooth to transfer a video?
- A.
LAN
- B.
MAN
- C.
PAN
- D.
WAN
Correct Answer
C. PANExplanation
When two mobiles are connected using Bluetooth to transfer a video, a Personal Area Network (PAN) is formed. A PAN is a network that connects devices within a short range, typically within a few meters. Bluetooth technology allows for wireless communication between devices in close proximity, making it ideal for creating a PAN. In this scenario, the two mobiles are directly connected to each other, forming a small network specifically for the purpose of transferring the video.Rate this question:

Domain name resolution is done by designated server called?
- A.
DND
- B.
DNS
- C.
DNA
- D.
DON
Correct Answer
B. DNSExplanation
Domain name resolution is done by a designated server called DNS (Domain Name System). DNS is responsible for translating domain names into IP addresses, allowing users to access websites and other resources on the internet using human-readable domain names instead of numerical IP addresses. DNS servers store a database of domain names and their corresponding IP addresses, and when a user enters a domain name in their web browser, the DNS server is queried to retrieve the corresponding IP address, enabling the connection to the desired website or resource.Rate this question:
