Networking And Hardware Quiz

A home computer network is sometimes also called a LAN (Local Area Network). This is because a LAN is a network that connects devices within a limited area, such as a home or office. It allows devices like computers, printers, and smartphones to communicate and share resources with each other. LANs are typically used in small-scale settings, making it an appropriate term to describe a home computer network. MAN (Metropolitan Area Network), WAN (Wide Area Network), and SAN (Storage Area Network) are different types of networks that are typically used in larger-scale environments or for specific purposes.

A firewall is a security measure that monitors and controls incoming and outgoing network traffic. Its purpose is to prevent unauthorized or unwanted network connections from being made. It acts as a barrier between a trusted internal network and an untrusted external network, filtering out potentially harmful or malicious connections. By blocking unauthorized access attempts, a firewall helps to protect the network and the devices connected to it from various cyber threats, such as hacking, malware, and unauthorized data access.

All of the options listed (DSL, DIAL-UP, Cable, and Wireless) are forms of Internet service. DSL (Digital Subscriber Line) uses existing telephone lines to provide high-speed Internet access. DIAL-UP is a method of connecting to the Internet through a telephone line and a modem. Cable Internet uses cable television infrastructure to deliver Internet connectivity. Wireless Internet service refers to accessing the Internet through wireless networks, such as Wi-Fi or cellular data connections. Therefore, all of these options are valid forms of Internet service.

A home network router enables safe sharing of resources among network devices in the home. This means that the router allows multiple devices such as computers, smartphones, and smart home devices to connect to the same network and share resources such as internet access, files, and printers. The router provides a secure and controlled environment for sharing these resources, ensuring that only authorized devices can access them and protecting the network from potential threats or unauthorized access.

A computer must have an IP address when connecting to a home network router, connecting to a Wi-Fi hotspot, and communicating with another computer using TCP. In all these scenarios, the IP address is necessary for the computer to establish a network connection and communicate with other devices. The IP address serves as a unique identifier for the computer on the network, allowing it to send and receive data. Therefore, all of the given options require the computer to have an IP address.

VOIP stands for Voice over Internet Protocol, which is a technology that allows users to make telephone calls over the internet. It converts voice signals into digital data packets and transmits them over the internet, eliminating the need for traditional phone lines. This technology has become popular due to its cost-effectiveness, flexibility, and ability to integrate with other communication services.

An IP address is a numeric quantity that identifies a network adapter to other devices on the network. It serves as a unique identifier for devices connected to a network, allowing them to communicate and exchange data with each other. The IP address is not related to the manufacturer of a computer or the physical location of a computer. Therefore, the correct answer is that an IP address identifies a network adapter to other devices on the network.

Limewire, Kazaa, and Bearshare are all well-known software applications that were used for peer-to-peer (P2P) file sharing. These applications allowed users to connect with each other and share files directly, without the need for a central server. Users could search for and download various types of files, including MP3 music files, videos, documents, and more. However, due to copyright infringement issues and legal challenges, these applications have been largely discontinued or replaced by more legal and regulated file sharing platforms.

A Virtual Private Network (VPN) connection can be established only when connected to the Internet. This means that regardless of the type of connection, whether wireless or Ethernet, as long as there is an active Internet connection, a VPN connection can be established. Therefore, the correct answer is "only when connected to the Internet".
