Hardware Mind Map

1. the CPU is a piece of hard ware often refferd to as the brain of the computer. it stores memory and does an important function to the computer

2. the CPU performance is how well it performs, so a better CPU will perform better

   • factors that affect the CPU s performance are things like clock speed where you get the CPU and amount of Ghz
   • ALU is a component for the CPU it stands for "arithmetic-logic unit
   • the central prossesing unit is also a component

3. ROM stands for "read only memory" and it contains the boot up instructions for the computer. so when you turn the computer on it turns on and comminicates with all the other hard ware. So it is very inportant. it also stores memory on a long term basis.

4. RAM stands for " random access memory" it stores memory for a short term amount. when you turn the computer off the memory gets wiped. The more RAM you have the more applications you can run

   • there are different RAM sizes andthe bigger the ram the more tempery memory and applications you can run

5. virtual memory is a memory manegment technique that provides an idealized abstraction of storage recourses. it is slower than RAM and is needed when the computer is running alot of applications.
