The speed of CPU is measured in?

The correct answer is Gigahertz. The speed of a CPU (Central Processing Unit) is primarily measured in Gigahertz (GHz). Gigahertz represents the clock speed of the processor, indicating the number of clock cycles the CPU can execute per second. A higher clock speed generally means the CPU can perform more operations and process instructions faster, contributing to the overall performance of the computer. Modern CPUs often operate in the range of several Gigahertz, providing immense processing power for complex tasks and applications.

Let's examine why the other options are incorrect:

• Megabytes: Megabytes (MB) are a unit of digital information, commonly used to measure the size of files, the capacity of RAM (Random Access Memory), or the amount of data stored on a hard drive. It measures size, not speed.
• Kilobytes: Kilobytes (KB) are also a unit of digital information, smaller than megabytes. Like megabytes, they are used to measure the size of data or storage capacity, not the processing speed of a CPU.
• bytes: Bytes are the fundamental unit of digital information, typically consisting of 8 bits. They are used to measure the size of data, such as characters or small files, but not the speed at which a CPU operates.
