What does CPU stand for and what does it do?
The Central Processing Unit is the brain of the computer and handles most of the processing and delegates jobs to other components
What is a GPU and what does it stand for
The Graphics Processing Unit renders images and allows them to be displayed on a screen.
What are some symptoms that the CPU is malfunctioning?
**Device will not power on since it is a vital component
Crashing or freezing
What is a Byte?
A Byte is a string of 8 bits
What is the MAXIMUM percent of your power supply that should be in use in order to be efficient.
80% of the maximum output of the power supply
What is an electrical short?
When an electrical circuit connects somewhere it isn't supposed.
This can lead to damaging of the circuit, damaging of a component, or even a small fire.

Convert 15 GB to MB
15,000 MB
What is the difference between dedicated and integrated graphics?
Integrated graphics cards use CPU resources to render images
Dedicated graphics use their own resources, and their own ram in order to render graphics
What component interconnects all other components?
Motherboard/ a Circuitboard
What is the difference between Storage and Memory
Storage is LONG TERM SAVING
Memory is SHORT TERM SAVING
