What is a network?
Correct Answer
B. Two or more computers
Explanation
A network refers to a group of two or more computers that are connected and can communicate with each other. This allows for the sharing of resources, such as files and printers, and enables users to access information and services from other computers within the network. By connecting computers together, a network facilitates communication and collaboration between users, making it easier to share information and work together efficiently.

What is the key benefit of working in a network?
Correct Answer
A. Sharing information and resources
Explanation
The key benefit of working in a network is the ability to share information and resources. By connecting multiple devices and users, a network allows for easy and efficient sharing of files, data, and equipment. This promotes collaboration, enhances productivity, and eliminates the need for duplicate resources. Additionally, it enables centralized management and control, making it easier to access and distribute information across the network.

What is the main problem with large networks?
Correct Answer
C. Viruses
Explanation
The main problem with large networks is the risk of viruses. Large networks are more susceptible to virus attacks due to the sheer number of devices connected to the network. Viruses can spread quickly and cause significant damage, compromising the security and functionality of the entire network. It becomes challenging to control and contain the spread of viruses in large networks, making it a major problem that needs to be addressed.

What are the three main types of topology?
Correct Answer
B. Bus, Ring and Star
Explanation
The three main types of topology are bus, ring, and star. In a bus topology, all devices are connected to a single cable, forming a linear network. In a ring topology, devices are connected in a circular manner, where each device is connected to two other devices. In a star topology, all devices are connected to a central hub or switch, creating a centralized network. These three types of topology are commonly used in computer networks to establish the physical layout and connectivity between devices.

Why is a ring network so fast?
Correct Answer
C. Data travels in only one direction
Explanation
A ring network is fast because data travels in only one direction. This eliminates the need for collision detection and allows for simultaneous data transmission, resulting in increased efficiency and speed. With data flowing in a single direction, there is no need for data packets to wait for their turn, reducing latency and improving overall network performance.
6.
What does LAN stand for?
Correct Answer
C. Local Area Network
Explanation
LAN stands for Local Area Network. This is a computer network that connects devices within a limited area such as a home, office, or building. It allows for the sharing of resources such as files, printers, and internet connections among connected devices. LANs are typically faster and more secure than wide area networks (WANs) as they cover a smaller geographic area.
