Which transmission method sends 1 bit at a time over a single physical wire, slower than parallel transmission?

• A. Serial Transmission
• B. Parallel Transmission
• C. Synchronous Transmission
• D. Asynchronous Transmission

Answer: (A)

Sends one bit at a time over a single wire is serial transmission. In serial transmission, data bits are transmitted sequentially on a single channel, one after another, which keeps wiring simple and cost-effective and avoids timing skew between multiple wires. This often makes it slower than parallel transmission for the same clock rate, but it scales well for long distances and high speeds with modern techniques. The other concepts in the options deal with how timing is managed rather than the amount of data carried by a single path: synchronous and asynchronous refer to clocking methods, while parallel transmission sends multiple bits at once over multiple wires, which is the opposite idea to serial.
