What is a Smartphone Processor and How Does it Work?

1. 1. The processor or Central Processing Unit (CPU) is an electronic circuitry fitted inside your device to process and respond to instructions coming from your Apps.
   2. To process the instructions, the CPU uses binary arithmetic and logic to best respond to the prompts given to it.
   3. The processor works hand in hand with the RAM, which is the memory that relays instructions to the CPU.
   4. As you use your phone, every Application you open resides in the Random Access Memory.
   5. It is from here where the instructions are broken into bits before being sent to the CPU for processing.
   6. It then executes those instructions for the final result/information you see on your screen.
   7. The processor is like the brain of your smartphone.
   8. A processor’s performance is evaluated by the number of cores it has as well as clock speeds.
   9. A core is an independent unit of the processor that executes instructions. The more cores the better the processor.
   10. Clock speed is the speed at which the processor executes instructions, measured in GHz.
   11. Processors come in the following cores;
       1. Dual-core (2)
       2. Quad-core (4)
       3. Octa-core (8)
       4. Hexa-core (6)
