A buffer is a device that isolates other devices. Typically, a buffer has a high input impedance and a low output impedance.
This means that it can accept signals with minimal loading effect (high input impedance) and provide a stable output signal (low output impedance). Buffers are commonly used in electronic circuits to prevent interference between different components and ensure proper signal transmission.

For example, in digital communication systems, input and output buffers are used in switches, routers, and other network devices. These buffers temporarily store data while it awaits processing by the device. When data arrives at the input, it is stored in the input buffer until the device is ready to process it. Similarly, the output buffer holds data before it is transmitted to the next device or destination.

In summary, buffers play a crucial role in maintaining signal integrity, preventing data loss, and ensuring efficient communication between devices.
