A router is a networking device that forwards data packets between computer networks. It connects different networks and directs data traffic based on IP addresses.

Components of routers include:

1. **CPU (Central Processing Unit)**: Processes data and manages routing functions.
2. **RAM (Random Access Memory)**: Temporarily stores routing tables and data packets.
3. **ROM (Read-Only Memory)**: Contains the firmware and boot instructions.
4. **Network Interfaces**: Ports for connecting to different networks (e.g., Ethernet, Wi-Fi).
5. **Power Supply**: Provides electrical power to the router.
6. **Routing Table**: A database that stores routes to various network destinations.

1. **Flag**: 1 byte (0x7E) indicating the start and end of the frame.
2. **Address**: 1 byte (0xFF) used for point-to-point communication.
3. **Control**: 1 byte (0x03) indicating the frame type.
4. **Protocol**: 2 bytes indicating the type of payload (e.g., IP, IPX).
5. **Payload**: Variable length containing the encapsulated data.
6. **FCS (Frame Check Sequence)**: 2 bytes for error checking.
