1. What is the purpose of DNS in networking?
DNS (Domain Name System) translates domain names into IP addresses, enabling devices to
locate and connect to each other over the internet.
2. Describe the function of an IP address in networking.
An IP address identifies a device on a network, allowing it to send and receive data across the
network.
3. What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses, allowing for a larger number of
unique addresses.
4. How does DHCP assist in network configuration?
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and other
network configuration settings to devices on a network.
5. What is the role of a subnet mask in networking?
A subnet mask divides an IP address into network and host portions, helping routers determine
the routing of data packets.
6. What is NAT, and how does it work?
NAT (Network Address Translation) allows multiple devices on a local network to share a single
public IP address for communication on the internet.
7. Explain the difference between a switch and a router.
1
, A switch connects devices within a local network, while a router connects multiple networks,
such as a local network to the internet.
8. What is the purpose of the OSI model in networking?
The OSI model provides a framework for understanding how different networking protocols
interact, with seven layers that represent different aspects of communication.
9. How does ARP (Address Resolution Protocol) function?
ARP resolves a device's IP address into its corresponding MAC (Media Access Control) address,
enabling communication on a local network.
10. What does the term "packet switching" mean in networking?
Packet switching breaks data into smaller packets, which are transmitted over a network and
reassembled at the destination.
11. What is the role of the application layer in the OSI model?
The application layer is responsible for interacting with the end user and enabling applications to
communicate over a network.
12. What is the difference between TCP and UDP?
TCP (Transmission Control Protocol) ensures reliable, ordered delivery of data, while UDP (User
Datagram Protocol) allows faster, but less reliable, transmission.
13. What is an IP address range?
An IP address range specifies a set of IP addresses within a network, which are used to assign to
devices within that network.
14. What does "pinging" a device in networking do?
Pinging sends a small packet of data to a device to check if it's reachable and measures the
response time.
