What describes the bandwidth of a system?

The concept of bandwidth in a system refers to the capacity of that system to transmit or process data over a particular period of time. In this context, it relates directly to how much information can be sent or received within a given timeframe, often measured in bits per second. This definition aligns perfectly with the idea of available or consumed information capacity, as bandwidth indicates the limits of data transfer capabilities.

When considering the other options, a data structure's static nature pertains more to its fixed size and organization rather than the speed or capacity for data handling. The rate of instructions processed per second focuses on the processing speed of the CPU, which is distinct from bandwidth. Lastly, the current amount of active data in memory describes a temporary state rather than a measure of throughput or capacity over time. Hence, the recognition of bandwidth as the available or consumed information capacity is essential for understanding data transmission and network performance.
