How computers work pt 2

Last post, I talked about how the CPU, RAM, storage, and motherboard in a computer are similar to different parts of the human body. This time, I am doing the same thing for the GPU, PSU, and peripherals.


The GPU, or graphics processing unit, is like the right side of the brain for a computer. It processes visuals that it is receiving from the rest of the system and sends them to the display. The PSU, otherwise known as the power supply, is like the heart of the computer. It sends power through to the system through wires just like how the heart sends nutrient-rich blood to the body through arteries and veins.


Humans wouldn’t be able to understand if a computer is working if it weren’t for peripherals. Peripherals include the mouse, keyboard, headphones or speakers, webcam, and display. The mouse and keyboard are like arms and legs. They manipulate items on the computer. The headphones or speakers are like the mouth. Both send out sound waves to be perceived by others. The webcam is like the eyes. It sends a visual to the rest of the system to be processed. Then the display is what others actually see of the computer. It is almost like the face of the body, sending visual signals to others.


Now that I have explained how computers are similar to the human body, biology class will feel like learning about computers and computer science will feel like biology. Thinking about computer parts as body parts has helped me troubleshoot and understand how computers work. Next week, I will teach how to build a body, wait I mean a computer.
