IP Address
IP Address
A unique identifier assigned to each device on a network. It's used to locate and communicate with devices. For example, 192.168.1.100.
Protocol
Protocol
A set of rules that dictate how data is transmitted across a network. It defines the format, order, and timing of communication.

Study Notes
Logical Address (IP)
- IP addresses are 32 bits long, divided into four 8-bit groups separated by periods.
- Each group can hold values from 0 to 255.
- 28 = 256 possible values per group.
- An IP address has two parts: Network (constant) and Host (changeable).
- The network part remains constant within a network, while the host part can change.
- Example: 192.1.1.0
Subnetting
- A subnet mask is used to distinguish the network and host portions of an IP address.
- The subnet mask uses a dotted-decimal format similar to the IP address.
- Example: 255.255.255.0
- The leading 1s in the subnet mask denote the network part of the address, and the trailing 0s denote the host part.
- In the example above, the first three groups (255.255.255) define the network portion, and the last group (0) signifies the host portion.
Protocols
- Protocols dictate how data is transferred across a network.
- Protocols like the AS algorithm define the rules for data transfer.
Static Routing
- Static routing is a method for configuring network paths.
Port
- Ports are used to identify specific applications or services on a network.
