Which term refers to the amount of data that can be transmitted over a network in a given timeframe?

1. Throughput

2. Latency

3. Bandwidth

4. Signal strength

The correct answer is: Bandwidth

The amount of data that can be transmitted over a network in a given timeframe is referred to as bandwidth. Bandwidth is a measure of the maximum data transfer capacity of a network connection, typically expressed in bits per second (bps), megabits per second (Mbps), or gigabits per second (Gbps). It indicates the upper limit on the amount of data that can be sent or received in a specified period and is a critical factor in determining the performance of network communications. Understanding bandwidth is essential because it helps to assess whether a network can handle the required data traffic for applications like streaming video, online gaming, or large file transfers. Higher bandwidth allows for more data to be sent simultaneously, leading to faster and more efficient communication across the network. This concept is different from other terms, such as latency, which refers to the delay before a transfer of data begins following an instruction, and throughput, which denotes the actual amount of data successfully transmitted over a network in a specific timeframe. Signal strength, on the other hand, measures the power level of a transmitted signal, and although it can affect both bandwidth and throughput, it does not directly describe the data transmission capacity itself.
