FREE Bachelor of Science in Computer Science : Network Fundamentals Questions and Answers
What is required for a computer to establish a connection with a network or other computer devices?
To establish a connection with a network or other computer devices, a computer requires a Network Interface Card (NIC). This hardware component allows the computer to communicate with other devices over the network by providing a unique network address and facilitating data transmission.
Which of the following is not among the components used for network connectivity?
A mouse is not included among the components used for network connectivity. While a Network Interface Card (NIC), hub, and cable are essential elements for establishing and maintaining network connections, a mouse is an input device used for interacting with a computer's graphical user interface and doesn't play a direct role in network connectivity.
Which Command Prompt command is used to verify an internet connection?
The correct command in Command Prompt to confirm an internet connection is "PING". This command sends a request to a specific server and waits for a response, indicating whether data packets can successfully travel to and from the server. It's a widely used tool to diagnose network connectivity issues.
What are the drawbacks of networks?
Disadvantages of networks include the potential vulnerability to viruses and malware, which can spread easily across connected devices and compromise the security and integrity of the networked systems.
What do peripherals primarily encompass?
Peripherals refer to devices that are connected to a computer system in order to enhance its functionality. These devices expand the capabilities of the computer system by adding features such as input, output, or storage options.
Networks facilitate the sharing of files among computers.
Networks are designed to enable communication and resource sharing between computers, which includes the exchange of files and data. This functionality is a fundamental aspect of networking, allowing users to access and transfer files seamlessly across connected devices.
What is the term for a computer network that links computers within a limited area such as an office building, school, or home?
The term for a computer network that connects computers within a confined geographical area, such as an office building, school, or home, is a Local Area Network (LAN). LANs are designed for local connectivity and efficient data exchange among devices in close proximity.
Which of the following pairs share the most similarities?
Among the provided options, the pair that exhibits the greatest resemblance is "Hub & Switch." These two devices, within a network context, are both used to connect multiple computers and devices together. However, a hub operates at a more basic level, transmitting data to all devices connected to it, while a switch is more intelligent, directing data only to the appropriate recipient, enhancing network efficiency.
What is the purpose of connecting computers into a network?
The primary reason for connecting computers into a network is to facilitate the sharing of files and resources among them. This enables efficient communication, data exchange, and collaboration among connected devices, leading to improved productivity and convenience.
Which equipment is employed to link numerous devices within a network, facilitating communication among them by transmitting data exclusively to the designated recipient?
A switch is utilized to interconnect multiple devices within a network, enabling efficient communication by directing data only to the intended recipient. This ensures optimal data transmission and minimizes unnecessary traffic.
What is the simplest device in a computer network that solely connects computers and lacks any additional functions?
The most basic device in a computer network that only serves the purpose of connecting computers without any additional features is a hub. It operates at the physical layer of the network and doesn't have the intelligence to manage data traffic like switches or routers do.
What is another term that can refer to a home computer network
A home computer network is often referred to as a LAN, which stands for Local Area Network. This term signifies a network that connects devices within a limited geographic area, typically a home or a small office. A LAN allows devices such as computers, printers, and smartphones to communicate and share resources with each other.
A network forms when a single device is linked to another.
The statement is false. A network is created when multiple devices are interconnected, allowing them to communicate and share resources with each other. Connecting a single device to another does not constitute a network.
What are the benefits of having a network?
The benefits of having a network primarily revolve around improved communication. Networks enable efficient data sharing, resource access, and collaboration among connected devices, leading to enhanced communication and productivity.
When is it necessary for a computer to possess an IP address?
It becomes necessary for a computer to have an IP address when connecting to a Wi-Fi hotspot. An IP address is essential for communication over a network, enabling the computer to identify and be identified by other devices on the network.
What does the term "Networking" refer to?
The term "Networking" refers to the connection and communication between two or more computers, allowing them to share resources, information, and services. It involves the establishment of a digital link that enables devices to interact and exchange data, enhancing collaboration and efficiency among connected systems.
