What's Inside a Computer?
This is what Vilma and I found when we first lifted the cover off our computer. I never opened a computer before. There are many different parts and each has a function. I will describe each of the parts and explain what they do. The computer is a complex machine that I use everyday but I never stop to think about what's inside. This lab helped me see computers in a new way.
The motherboard is in the middle of the bottom cover. The lines represent wired connections between various components on the motherboard. Th motherboard serves as a connection to and from other parts of the computer.
The Power Supply
This is the processor after I took it off of the motherboard. It was easy to remove when I pulled on the plastic handle.
Random Access Memory aka RAM
The hard disk is located in the top right side of the lid of the computer. We disconnected the wires to remove it and opened the case protecting it. It has a capacity of 40 GB of data. The hard-disk is a shiny plate connected to a small chip and plate that retrieves and records data.
This is a photo of the mysterious LED we found inside the computer. Vilma and I couldn't figure out why there was an LED inside the computer where no one will be able to see it.
The Optical Disk
The frequency of the processor is controlled by the crystal.
