Networks Lesson 2 Quiz

Explanation
Networking refers to the ability of two or more computers to establish communication and connect with each other. This involves the exchange of data, information, and resources between the connected computers. Therefore, the statement "Networking is when two or more computers are able to communicate and connect with each other" is true, as it accurately describes the concept of networking.

Explanation
A Campus Area Network (CAN) refers to a network connecting computers in a limited distance. This type of network is typically used within a specific geographical area, such as a university campus or a corporate office complex. It allows for the sharing of resources and communication between computers within the defined area. Unlike a Wide Area Network (WAN) that covers larger distances, a CAN is designed to serve a localized area.

Explanation
Mainframe computers are known for their ability to store large amounts of data, not small amounts. They are designed to handle massive amounts of information and support multiple users simultaneously. Additionally, mainframes often run complex and specialized software applications that are tailored to specific organizational needs, rather than just customized software. Therefore, the statement that mainframe computers usually store customized software and small amounts of data is false.

Explanation
If there is an error with the server in a network, it can lead to the disruption of the entire network. This is because the server acts as the central point of control and communication for the network. If the server fails or experiences any issues, it can cause all connected devices and services to become inaccessible or malfunction. This can result in loss of productivity, communication breakdown, and potential data loss. Therefore, it is a significant disadvantage of networking.

Explanation
To be connected to a network, having a network interface card (NIC) installed on your computer is necessary. The NIC allows your computer to communicate with other devices on the network. It acts as an intermediary between your computer and the network, enabling data transmission. Additionally, it is important to ensure that the NIC is set up correctly so that it can recognize and establish a connection with the network. Therefore, the statement "To be connected to a network, you need to have a network interface card (NIC) installed on your computer and make sure it is setup correctly to recognize the network" is true.

Explanation
The given statement is false because there are more than two types of common networks that we use. Some examples of common networks include LAN (Local Area Network), WAN (Wide Area Network), MAN (Metropolitan Area Network), WLAN (Wireless Local Area Network), and VPN (Virtual Private Network), among others. Therefore, the statement that there are only two types of common networks is incorrect.

Explanation
HAN stands for Home Area Network in terms of networking. A Home Area Network refers to a network that connects devices within a person's home, allowing them to share resources, such as internet access and printers, among other devices. This network is typically used for personal use and is separate from larger networks, such as Wide Area Networks (WANs) or Local Area Networks (LANs).

Explanation
Setting up a network typically requires technical knowledge and access to network infrastructure, which is usually managed by an administrator. Users generally do not have the necessary permissions or expertise to set up a network on their own. Therefore, the statement is false.

Explanation
This statement is true because in a centralized network system, all data flows to and from a central server or mainframe computer. This central server controls the flow of information and manages the network resources. Other computers or devices in the network depend on this central server for communication and data exchange. This centralized architecture allows for easier management and control of the network, but it can also be a single point of failure if the central server goes down.

Explanation
The correct answer is "Server". In a network, the server is responsible for holding and managing the data. It acts as a central repository where files, documents, and other information are stored and can be accessed by other devices connected to the network, such as PCs. Mr. Thiara is not a relevant option as it does not pertain to network infrastructure or data storage.
