Question

Speed of processor chip is measured in ______.
1. Mbps
2. MHz
3. Bits per second
4. Bytes per second

Answer 1

Correct Answer - Option 2 : MHz

The correct answer is MHz.

• Speed of Processor
  • ​Processor speed is relative to the clock speed which is measured in units of cycles per second.
  • CPUs run at rates of millions and billions of Hertz, megahertz(MHz) and gigahertz(GHz).
  • A clock speed of 3.5 GHz to 4.0GHz is generally considered a good processor speed.

• Processor(CPU)
  • A CPU is also called a central processor, main processor, or just processor, is the electronic circuitry that executing instructions comprising a computer program.
  • The CPU performs basic arithmetic, logic, controlling, and input/output operations specified by the instructions in the program.
  • The fundamental operation of most CPU's regardless of the physical form they take is to execute a sequence of stored instructions called a program. 
• Instructions cycle in Processor(CPU)
  • All CPU's follows the following steps in order to complete their operations:
    1. Fetch: The first step, involves retrieving instructions from the program memory.
    2. Decode: The instruction that the CPU fetches from the memory determines what the CPU will do, which is decoded by the instructor decoder.
    3. Execute: In this step, all the desired functions are performed as per the instructions decoded.
