Why are buffers often required in an 8086 - based system?

Buffers are often required in an 8086-based system to manage data flow between components that operate at different speeds. The 8086 microprocessor may process data faster than peripherals like memory or I/O devices can provide it, leading to potential data loss or corruption. Buffers help to temporarily store data, allowing the CPU to continue processing while ensuring that data is transferred reliably and efficiently. This is crucial for maintaining system stability and performance in multitasking environments.
