What is the name of the protocol used for translating human-readable domain names, such as "www.example.com," into IP addresses used by computers for identifying websites?
Domain Name System (DNS).
What is the name of the device used to amplify and transmit signals over long distances in a telecommunications network?
Repeater
What’s a standard for wireless local area networks (WLANs) that allows devices to connect to the internet without using wires?
Wi-Fi
What is the name of the network that allows devices to communicate wirelessly over short distances, such as for Bluetooth or Wi-Fi?
Wireless Local Area Network (WLAN) or Wireless Personal Area Network (WPAN).
What is a virtual private network (VPN)?
A network that interconnects multiple local area networks (LANs) across different locations.
What is VoIP?
VoIP (Voice over Internet Protocol): A technology that allows for the transmission of voice calls over the internet.
What is an access point?
A device that allows devices to connect to a wired network wirelessly, typically used in Wi-Fi networks.

4G/5G
What is the term used to describe the set of rules and protocols that govern the transmission of data over the internet?
Internet Protocol (IP)
What is the name of the network topology that allows devices to communicate with each other without the need for a central server, and is commonly used in IoT (Internet of Things) applications?
Mesh network
What is FTP?
FTP (File Transfer Protocol): A standard protocol used for transferring files over a network, commonly used for file sharing.
What is a firewall?
A security device that monitors and filters incoming and outgoing network traffic to protect against unauthorized access.
