  1. What does "IP" stand for in networking?

    Answer: Internet Protocol

    IP stands for Internet Protocol, which is the principal communications protocol in the Internet protocol suite. It defines how data packets are addressed and routed from the source host to the destination host across different networks, forming the basis of internet communication.

  2. Which of the following is a Layer 3 device in the OSI model?

    Answer: Router

    A router operates at Layer 3 (the Network Layer) of the OSI model, responsible for forwarding data packets between different computer networks. It uses IP addresses to determine the best path for data transmission, enabling communication across diverse networks.

  3. What is the primary function of DNS in networking?

    Answer: To convert domain names into IP addresses

    The primary function of DNS (Domain Name System) in networking is to translate human-readable domain names (like example.com) into machine-readable IP addresses. This allows users to access websites and other network resources using memorable names instead of numerical IP addresses.

  4. Which protocol is used to transfer files between a client and a server over a network?

    Answer: FTP

    FTP (File Transfer Protocol) is a standard network protocol specifically designed for transferring computer files between a client and a server over a network. It is commonly used for uploading and downloading files to and from web servers and other remote systems.

  5. What is the purpose of a subnet mask in IP addressing?

    Answer: To divide an IP address into network and host portions

    A subnet mask is used in IP addressing to differentiate the network portion of an IP address from the host portion. This division allows for the creation of smaller, more manageable subnetworks within a larger network, improving efficiency, security, and organization of network resources.
