Final answer:

Disk performance is typically described using seek time, rotational latency, and data transfer rate. These factors collectively determine the efficiency and speed of computer data storage and retrieval processes. Measuring these can be compared to calculating an athlete's sprint speed by distance and time measurements.

Step-by-step explanation:

The parameters that could be used to describe disk performance are seek time, rotational latency, and data transfer rate. These are critical for understanding how quickly a disk drive can access and move data. Seek time is the time it takes for the disk's read/write head to move to the location where the data is stored. Rotational latency refers to the time it takes for the disk to rotate to the proper position under the read/write head. Lastly, the data transfer rate is the speed at which data can be read from or written to the disk. These parameters are important to consider when evaluating the performance of a computer's storage system.

Understanding the relationship between these parameters can be analogous to measuring the average speed of an athlete running sprints by using the distance covered and the time taken to complete the sprint. Just as in the calculation of speed, the performance of a disk drive is calculated using these measured properties and their relationships. In the context of data storage, computer storage space is measured in units such as kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB), each reflecting a measure of how much data can be stored, with one KB equivalent to 1,024 bytes.
