Basic Information Technology Quiz For Beginners

A LAN, or Local Area Network, is a network that connects devices within a limited area such as a home, office, or school. It allows for the sharing of resources, such as printers and files, and enables communication between devices within the network. Therefore, the statement "A LAN is a LOCAL AREA NETWORK" is true as it correctly defines what a LAN is.

The given answer is true because a switch is a networking device that provides a connecting point for cables. It allows multiple devices to be connected and communicate with each other within a local area network (LAN). Switches receive data packets from connected devices and forward them to the appropriate destination device based on the MAC address. This enables efficient and secure communication between devices on the network.

If a digital line is available, a special modem is required, and the correct answer is ADSL. ADSL stands for Asymmetric Digital Subscriber Line, which is a type of modem used to connect to the internet over a digital line. ADSL modems are specifically designed to provide high-speed internet access over existing telephone lines, allowing for faster download speeds compared to traditional dial-up modems.

A Wide Area Network (WAN) is a network that spans a large geographical area, such as multiple cities or even countries. It connects multiple local area networks (LANs) and allows for the transmission of data and communication between different locations. The term "wide" refers to the large area covered by the network, which can be achieved through various means, including wired or wireless connections. Therefore, the correct answer is Wide Area Network (WAN).

Communication devices such as smartphones, laptops, and tablets enable computer users to communicate with people through various means such as phone calls, text messages, emails, and video chats. These devices also allow users to exchange data and information through file sharing, online collaboration tools, and internet connectivity. Additionally, communication devices provide access to various forms of entertainment such as streaming videos, playing games, and browsing social media platforms. Therefore, the correct answer is "All of the Above" as communication devices enable computer users to communicate, exchange data, and seek entertainment.

An NIC (Network Interface Card) is a hardware component that allows a computer to connect to a network. It enables communication between the computer and the network using a specific network technology. Ethernet is a widely used network technology that allows for high-speed data transmission over local area networks (LANs). Therefore, it is plausible to assume that an NIC would work with Ethernet as the network technology.

External adaptors can come in different forms, including ExpressCard, MemoryCard, and NetworkCard. This means that all of the options listed are correct. ExpressCard adaptors are used to add functionality to laptops, MemoryCard adaptors are used to read and write data from memory cards, and NetworkCard adaptors are used to connect devices to a network. Therefore, the correct answer is "All of the above."

A router is a communication device that connects multiple networks. It acts as a bridge between different networks, allowing data to be transmitted between them. It determines the most efficient path for data packets to travel and forwards them accordingly. By connecting multiple networks, a router enables devices on different networks to communicate with each other. Therefore, the correct answer is "A communication device that connects multiple networks."
