Protocol Conversion

A protocol is a set of rules and standards that governs the connection, communication, and data transfer between devices. Different devices or systems may use different protocols, so protocol conversion is necessary to ensure proper communication.

• Protocol Conversion:
  • Ensures that the communication protocols used by a peripheral are compatible and can be understood by the computer, and vice versa.
  • It allows devices with different communication standards to work together, ensuring smooth data transmission.

Handling of Status Signals

Status signals provide feedback about the operational state of a peripheral device, such as whether it is ready to send or receive data. These signals are important for:

• Informing the user or system if there is a problem (e.g., printer out of paper).
• Ensuring that the computer does not attempt to communicate with a non-ready device.
• This information helps the interface manage device communication efficiently and notify the user if an issue arises.

Key Functions:

• Protocol Conversion: Makes sure different devices communicate properly.
• Status Signals: Indicate if a device is ready or if there’s an issue requiring user intervention.
