What is the purpose of Binary Synchronous Communication (BSC)?

The purpose of Binary Synchronous Communication (BSC) is to facilitate the transmission of data in a synchronous manner, specifically by sending bits in timed frames. This method ensures that the sender and receiver are synchronized, allowing for reliable and efficient communication. BSC uses control characters to define the start and end of each frame, enabling the orderly transmission of data and ensuring that both devices are in sync regarding when to send and receive bits.

This timing aspect is crucial in digital communication, as it helps prevent data collisions and ensures that each piece of information is received correctly without loss or confusion. The frame-based structure of BSC is particularly efficient for serial data transmission, where timing and synchronization are key to maintaining data integrity during communication.

The other options do not accurately describe the primary function of BSC. For instance, BSC is not limited to audio signals, nor does it focus on data encryption or the establishment of wireless connections. Its main role is centered around the synchronized transmission of binary data, which is fundamental to various data communication protocols.
