Question

Data rate is :

• A. Interfaces
• B. Media Representation
• C. Transmission rate
• D. Devices

Hint:

Think of data rate as the "speed limit" of a network connection. It's the maximum rate at which information can travel, which is precisely what transmission rate means.

Answer 1

The Correct Option is C

Step 1: Define Data Rate. Data rate, in the context of data communication, refers to the speed at which data is transferred from one device to another. It is typically measured in bits per second (bps), kilobits per second (kbps), megabits per second (Mbps), etc.

Step 2: Relate to other terms. "Transmission rate" is a synonym for data rate. Both terms describe the speed of data transfer over a communication channel.

Step 3: Analyze the other options. \[\begin{array}{rl} \bullet & \text{Interfaces: These are the physical and logical connection points between devices.} \\ \bullet & \text{Media Representation: This refers to how data is encoded (e.g., as electrical signals, light pulses).} \\ \bullet & \text{Devices: These are the hardware components of a network (e.g., routers, switches).} \\ \end{array}\] While these are all related to data communication, only "Transmission rate" is a direct equivalent of "Data rate".
