CompTIA ITF+ Practice Test

A kilobyte is not a measurement of processing speed, as processing speed is usually measured in GHz or MHz. A kilobyte is not a measurement of network bandwidth, as network bandwidth is usually measured in Mbps or Gbps. A kilobyte is not a measurement of memory capacity, as memory capacity is usually measured in GB or TB. These options are incorrect because they do not accurately describe what a kilobyte is. A kilobyte is a unit of measurement for digital data storage, equivalent to 1,000 bytes. It is often used to measure the size of files or the amount of data that can be stored in a device. Therefore, option B is the best answer as it correctly identifies that a kilobyte is a measurement of storage.
