What transmission process allows multiple data bits to be sent simultaneously, with each bit traveling along a separate channel?

The correct answer is parallel transmission, which refers to the method of sending multiple bits of data at the same time over separate channels or wires. This approach allows for a higher data transfer rate because different bits are transmitted simultaneously rather than sequentially. For example, in a parallel transmission setup, an 8-bit byte can be sent over eight separate wires, ensuring all bits reach their destination at the same time.

This is particularly useful in situations where speed is a critical factor, such as within computer memory and internal data buses of a computer where quick access to data is essential. Parallel transmission can be more efficient than its counterpart, serial transmission, which sends bits one after the other over a single channel, potentially causing delays in transmission as each bit must wait its turn.

Understanding parallel transmission is vital as it demonstrates a key concept in data communication and how hardware can be optimized for performance.
