Author: Sofia PC

Grade Level: 7th - 10th;  Type: Computer Science

Objective

In this experiment, we will discover whether leaving a computer on 24/7 will lead to more frequent crashes, freezes, and an overall slower processing speed. We will be experimenting with 2 brand new, identical computers to eliminate or lessen any other possible “other” factors.

Introduction

Computers are the forefront of technology. They can accomplish many tasks in a fraction of the time than if you were to do it manually. Some super computers can do jobs that are near impossible for humans to master. There are hundreds and thousands of uses for computers.

Since computers are like mechanical brains, doesn't this mean that it also needs sleep because people need it to rest their brains?

Research Questions

  • Do you turn your computer off when you're not using it? Put it to sleep?
  • What are the advantages of turning a computer off when not in use?

Materials

  • 2 brand new identical computers w/ monitors (any brand, but these instructions are written for Windows Vista or XP Platforms)
  • Time & Patience

Terms to Know

  • Computer
  • Processor
  • Computer speed
  • Abilities of computers
  • Putting a computer to sleep
  • Energy consumption

Experimental Procedure

  1. Plug both computers in to a power source and turn it on.
  2. Follow any necessary start-up instructions on the computers.
  3. You are not going to do anything else to these computers but experiment with them.
  4. Pick one computer to be the one you leave on 24/7 and the other one for the one you let “rest”.
  5. Every 3 hours, turn the “resting” computer off for 1 hour and turn it back on and repeat. At night, turn the computer off and turn it back on in the morning. Do not touch the other computer.
  6. After 1 month of this pattern, observe the CPU speed/performance by going into your task manager. Observe the month-by-month differences in CPU Speed.
