Bits Per Second (bps) is defined as?

• A. A measure of energy used by the device.
• B. The rate at which data bits are transmitted per second.
• C. The maximum physical wiring capacity in hertz.
• D. The protocol used to secure wireless connections.

Answer: (B)

Bits per second captures how fast data moves over a digital link by measuring the rate at which data bits are transmitted each second. That direct link to speed is why speeds are expressed as kbps, Mbps, or Gbps—the number of bits that can be sent per second. For example, a 1 Mbps connection transmits about one million bits every second, and remember that bytes are eight bits, so a 1 MB file involves about 8 megabits of data. Other options describe different ideas: energy use, frequency in hertz, or a security protocol, none of which define data transmission rate.
