Networking: A Basic Wi-fi Quiz!

The correct answer is "Popular technologies and standards for wireless computer networking". This answer accurately describes Wi-Fi as a set of technologies and standards that enable wireless computer networking. Wi-Fi allows devices to connect to the internet or communicate with each other without the need for physical cables. It has become a widely adopted and popular method of wireless communication in various settings such as homes, offices, and public spaces.

A home router enables safe sharing of resources among network devices in the home. It acts as a central hub that allows multiple devices such as computers, smartphones, and smart home devices to connect to the internet and share data securely. It provides a secure network connection, assigns IP addresses to devices, and allows for the creation of a local area network (LAN) within the home. This enables devices to communicate with each other, share files, printers, and other resources, and access the internet safely.

A home computer network is sometimes also called a LAN, which stands for Local Area Network. This term refers to a network that connects devices within a limited area, such as a home or office building. LANs are commonly used to share resources, such as printers and internet connections, among multiple devices in a localized area.

A firewall is a security measure that helps prevent unauthorized access to a computer network. It acts as a barrier between the internal network and the external network, such as the internet. By monitoring and controlling incoming and outgoing network traffic, a firewall can block unwanted or malicious connections, protecting the network from potential threats and unauthorized access attempts. Therefore, the purpose of a firewall is to prevent unwanted network connections from being made.

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 an IP network. VoIP offers cost savings, flexibility, and various features such as video conferencing and call forwarding. It has become a popular alternative to traditional phone systems, especially for businesses and individuals who need to make long-distance or international calls.

Bluetooth technology supports networking over its own standard wireless radio connections. Bluetooth is a wireless communication technology that allows devices to connect and exchange data over short distances. It uses radio waves to establish a connection between devices, eliminating the need for cables or wires. Bluetooth technology is commonly used for connecting devices such as smartphones, tablets, laptops, and speakers, enabling them to share files, stream audio, and control other devices.

Limewire, Kazaa, and Bearshare are all software applications that were commonly used for peer-to-peer (P2P) file sharing. P2P file sharing allows users to directly share files with each other without the need for a centralized server. These applications were popular for sharing music, videos, and other files, but they were also known for being used to share copyrighted material illegally.

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. This is because IP addresses are necessary for identifying and establishing connections between devices on a network. Playing media from the hard drive does not require an IP address as it is a local operation within the computer.

An IP address is a numeric quantity that identifies a network adapter to other devices on the network. It is used to establish communication and routing between different devices in a network. The IP address does not provide information about the manufacturer of a computer or the physical location of a computer.

A VPN connection can be established using various types of internet connections, including both wired connections like Ethernet and wireless connections such as Wi-Fi or cellular data. The primary requirement for setting up a VPN is having an active internet connection, as VPNs are designed to create a secure and encrypted tunnel between your device and a remote network over the internet.

DSL, Cable, Dialup, ISDN, and Satellite are all forms of Internet service. DSL (Digital Subscriber Line) uses existing telephone lines to provide high-speed internet access. Cable internet uses the same coaxial cables that deliver cable television to provide internet access. Dialup internet uses a modem and a telephone line to establish a connection to the internet. ISDN (Integrated Services Digital Network) is a digital telephone network that can provide internet access. Satellite internet uses satellites to provide internet access to remote areas.
