Study Notes
Internet Protocol
- The Internet uses the Internet Protocol (IP) as its primary communication protocol.
- IP allows devices to communicate with each other and route data packets between them.
IP Address
- An IP address is a unique identifier assigned to each device connected to a network.
- It consists of four numbers separated by dots, ranging from 0 to 255 (e.g., 192.0.2.1).
- IP addresses are used to locate and address devices on a network.
DNS Server
- A Domain Name System (DNS) server is a database that translates human-readable domain names into IP addresses.
- DNS servers allow users to access websites and online resources using easy-to-remember domain names instead of difficult-to-remember IP addresses.
- When a user enters a domain name, the DNS server looks up the corresponding IP address and directs the user to the desired website.
