Understanding Buffers in Parallel Ports
In parallel ports, buffering is essential for managing data transfer between the computer and peripheral devices. Buffers temporarily hold data to ensure smooth communication and synchronize data flow.
Data Direction Register (DDR)
- The Data Direction Register (DDR) plays a crucial role in enabling buffers in parallel ports.
- It determines whether the data lines are configured as input or output.
- When set to output, the DDR allows the parallel port to send data to connected devices, enabling the use of buffers to store this data temporarily before transmission.
Functionality of Other Registers
- Data Register: While it holds the data being sent or received, it does not directly enable buffering.
- Individual Control Register: This register controls specific functions of the parallel port but does not set the direction for data flow.
Conclusion
- The correct answer is option 'B' because the Data Direction Register is responsible for enabling buffering by configuring the data lines appropriately.
- This configuration is vital for ensuring that data is handled efficiently, allowing for seamless communication between the computer and peripheral devices.
Understanding the role of the Data Direction Register is essential for anyone working with parallel ports and their buffering mechanisms.
