Question

1. megahertz is the

o speed of the keyboard.

o speed of the printer.

o speed of the cpu.

o speed of the hard disk.

Explanation:

Megahertz (MHz) is a unit of measurement for frequency. In the context of computer components, it is used to measure the clock speed of the Central Processing Unit (CPU). The CPU's clock speed determines how many instructions it can execute per second. Keyboards, printers, and hard disks do not use megahertz to measure their speed. Keyboards are typically measured in terms of response time or polling rate (in milliseconds), printers in pages per minute, and hard disks in data transfer rates (e.g., megabytes per second).

Answer:

speed of the CPU.
