Here's a breakdown:
* Handshaking refers to the initial exchange of signals and data between two devices to establish a connection and agree on communication parameters. This ensures that both devices are ready and compatible before transferring data.
* Modems (Modulator-Demodulator) are devices that convert digital data into analog signals (modulation) for transmission over analog lines like telephone lines and vice-versa (demodulation).
The handshaking process for modems involves several steps:
1. Dialing: The modem initiates the connection by dialing the recipient's number.
2. Carrier Detection: The receiving modem detects the incoming carrier signal, indicating the start of the connection.
3. Synchronization: Both modems synchronize their timing and frequencies.
4. Negotiating Communication Parameters: The modems negotiate the speed, error correction methods, and other communication settings.
5. Data Transmission: Once the handshaking is complete, data can be transmitted.
This entire process of establishing a connection and setting up the communication parameters is known as handshaking.
