Study Notes
IP Addresses and Port Numbers
- An IP address is a unique identifier assigned to each device on a computer network, allowing devices to communicate with each other.
- IP addresses are represented as a series of four numbers separated by dots (e.g., 192.0.2.1), known as dotted decimal notation.
Port Numbers
- Port numbers are used to identify specific processes or services running on a device, allowing multiple applications to share the same IP address.
- Each computer with an IP address typically has 65,535 logical ports, which are divided into three ranges: well-known ports (0-1023), registered ports (1024-49151), and dynamic ports (49152-65535).
Domain Names
- A domain name is a human-readable alias for an IP address, making it easier for users to access websites and other online resources.
- The primary purpose of a domain name is to provide a memorable and easy-to-remember alternative to an IP address.
- Domain names are translated to IP addresses using the Domain Name System (DNS).
