Which factor is mentioned as affecting the rate of data transfer for electrical signals?

• A. Keyboard type
• B. Data storage type
• C. Data transmission methods
• D. CPU clock speed

Answer: (C)

Data transfer rate for electrical signals is determined by how the data is transmitted over the communication channel. The way you transmit—serial versus parallel, the signaling rate, encoding schemes, and protocol overhead—sets how many bits can be carried each second and how efficiently the link is used. A high-speed transmission method or a wide, efficiently encoded channel will move data faster, while slower or more overhead-heavy methods slow it down. The other factors don’t set the channel’s carrying capacity: keyboard type affects input generation, data storage type affects local access, and CPU clock speed affects processing rather than the actual signal transfer rate.
