Q51. Which of the following is a type of distributed computing system that provides on-demand computing resources and services over the internet, often on a pay-as-you-go basis?
a) Cluster computing
b) Grid computing
c) Cloud computing
d) Parallel computing
Show Answer
Correct Answer: c) Cloud computing
Explanation: Cloud computing is a type of distributed computing system that provides on-demand computing resources and services over the internet, often on a pay-as-you-go basis. Cloud computing allows users to access and use computing resources, such as processing power, storage, and software applications, without the need to own or manage the underlying infrastructure. This can provide increased flexibility, scalability, and cost savings compared to traditional computing models.
Q52. Which of the following network topologies combines two or more different topologies to create a more flexible and scalable network?
a) Bus topology
b) Ring topology
c) Tree topology
d) Hybrid topology
Show Answer
Correct Answer: d) Hybrid topology
Explanation: Hybrid topology is a network topology that combines two or more different topologies to create a more flexible and scalable network. In a hybrid topology, different parts of the network can use different topologies, such as a combination of star, ring, or mesh topologies, depending on the specific requirements and constraints of each part. Hybrid topologies can provide the advantages of multiple topologies while minimizing their drawbacks, making them suitable for large and complex networks.
Q53. Which of the following is a type of switching technique that divides data into small packets and transmits them independently over a shared network?
a) Circuit switching
b) Message switching
c) Packet switching
d) Cell switching
Show Answer
Correct Answer: c) Packet switching
Explanation: Packet switching is a type of switching technique that divides data into small packets and transmits them independently over a shared network. In packet-switched networks, data packets can take different paths to reach their destination, and they are reassembled at the destination to form the original data. Packet switching is more efficient than circuit switching, as it allows multiple communication sessions to share the same network resources simultaneously. It is commonly used in modern computer networks, such as the Internet.
Q54. In the OSI model, which layer is responsible for converting data into a format that can be transmitted over the physical medium?
a) Physical layer
b) Data link layer
c) Network layer
d) Transport layer
Show Answer
Correct Answer: a) Physical layer
Explanation: In the OSI model, the physical layer is responsible for converting data into a format that can be transmitted over the physical medium. The physical layer manages the electrical, mechanical, and functional aspects of the data transmission, such as signal encoding, voltage levels, and connector types. It ensures that the data is transmitted reliably and accurately over the physical medium, whether it is a wired or wireless connection.
Q55. Which of the following is a type of routing technique that dynamically adjusts the path for data transmission based on network conditions, such as congestion or link failures?
a) Static routing
b) Dynamic routing
c) Adaptive routing
d) Source routing
Show Answer
Correct Answer: c) Adaptive routing
Explanation: Adaptive routing, also known as dynamic routing, is a type of routing technique that dynamically adjusts the path for data transmission based on network conditions, such as congestion or link failures. In adaptive routing, routers continuously monitor the network and exchange information about the current state of the network. They use this information to determine the best path for data transmission, taking into account factors such as link capacity, congestion, and latency. Adaptive routing can provide more efficient and reliable data transmission compared to static routing, but it requires more processing overhead and can be more complex to implement.
Q56. Which of the following is a type of routing technique that allows the sender to specify the path for data transmission, rather than relying on the network routers to determine the path?
a) Static routing
b) Dynamic routing
c) Adaptive routing
d) Source routing
Show Answer
Correct Answer: d) Source routing
Explanation: Source routing is a type of routing technique that allows the sender to specify the path for data transmission, rather than relying on the network routers to determine the path. In source routing, the sender includes the complete route information in the data packet, and the routers along the path simply forward the packet according to the specified route. Source routing can be useful in certain scenarios, such as network testing or troubleshooting, but it can also introduce security risks, as it allows the sender to control the path of the data.
Q57. Which of the following is a type of wireless network that covers a small geographical area, such as a single room or a building?
a) Wireless Local Area Network (WLAN)
b) Wireless Personal Area Network (WPAN)
c) Wireless Metropolitan Area Network (WMAN)
d) Wireless Wide Area Network (WWAN)
Show Answer
Correct Answer: a) Wireless Local Area Network (WLAN)
Explanation: A Wireless Local Area Network (WLAN) is a type of wireless network that covers a small geographical area, such as a single room or a building. WLANs are typically used to provide wireless connectivity for devices, such as laptops, smartphones, and tablets, within the covered area. They use radio frequency (RF) technology, such as Wi-Fi, to enable high-speed data transmission and communication between devices without the need for a wired connection.
Q58. Which of the following is a type of wireless network that covers a medium-sized geographical area, such as a city or a region?
a) Wireless Local Area Network (WLAN)
b) Wireless Personal Area Network (WPAN)
c) Wireless Metropolitan Area Network (WMAN)
d) Wireless Wide Area Network (WWAN)
Show Answer
Correct Answer: c) Wireless Metropolitan Area Network (WMAN)
Explanation: A Wireless Metropolitan Area Network (WMAN) is a type of wireless network that covers a medium-sized geographical area, such as a city or a region. WMANs are typically used to provide high-speed wireless connectivity between different locations within the covered area, such as between buildings or across a city. They use technologies such as WiMAX or microwave links to enable long-range, high-speed data transmission.
Q59. Which of the following is a type of wireless network that covers a very small geographical area, such as the immediate vicinity of a device?
a) Wireless Local Area Network (WLAN)
b) Wireless Personal Area Network (WPAN)
c) Wireless Metropolitan Area Network (WMAN)
d) Wireless Wide Area Network (WWAN)
Show Answer
Correct Answer: b) Wireless Personal Area Network (WPAN)
Explanation: A Wireless Personal Area Network (WPAN) is a type of wireless network that covers a very small geographical area, such as the immediate vicinity of a device. WPANs are typically used for short-range communication between devices, such as smartphones, tablets, and wearable devices. They use low-power wireless technologies, such as Bluetooth and Zigbee, to enable communication between devices without the need for a central infrastructure.
Q60. Which of the following is a type of distributed computing system that allows multiple computers to work together on a common task, sharing their processing power, memory, and storage resources?
a) Cluster computing
b) Grid computing
c) Cloud computing
d) Cooperative computing
Show Answer
Correct Answer: d) Cooperative computing
Explanation: Cooperative computing is a type of distributed computing system that allows multiple computers to work together on a common task, sharing their processing power, memory, and storage resources. In cooperative computing, the computers collaborate to solve a problem or complete a task, often using specialized software and communication protocols to coordinate their efforts. This approach can provide increased performance, reliability, and scalability compared to using a single computer or a local cluster.
