Which of the following BEST describes a kilobyte?
Click on the arrows to vote for the correct answer
A. B. C. D.A.
Answer A is correct.
A kilobyte (KB) is a unit of measurement used to describe storage capacity in computing. It is equal to 1,024 bytes. Kilobytes are commonly used to describe the size of files, such as documents, images, or audio files, as well as the amount of memory in a computer system. For example, a file size of 100KB means that the file contains 100,000 bytes of data.
Answer B is incorrect.
Kilobits per second (Kbps) is a unit of measurement used to describe data transfer rates or throughput. It is commonly used to describe internet connection speeds, but it does not measure storage capacity. For example, a download speed of 100Kbps means that the download speed is 100,000 bits per second.
Answer C is incorrect.
A kilowatt (KW) is a unit of measurement used to describe power consumption or power output. It is commonly used to describe the power of electrical appliances, generators, or engines. For example, a 100KW generator can produce 100 kilowatts of power.
Answer D is incorrect.
Kilohertz (KHz) is a unit of measurement used to describe processor speed or clock speed. It measures the number of clock cycles per second in a processor. For example, a processor with a clock speed of 2.4KHz can perform 2.4 billion clock cycles per second. However, kilohertz is not the correct unit of measurement for describing processor speed in modern computing, as processors now operate in gigahertz (GHz) or higher frequencies.
