Computer Performance

1. RAM

2. Cores

   • How many independent processors there is inside the computer
   • The more independent processors there is inside of the CPU, the quicker they can figure out one problem or multiple problems at the same time.
   • By increasing the amount of independent processors, the more things you can do simultaneously
   • Fetch-Decode-Execute

3. Cache

   • Cache is a small piece of memory that is inside of the CPU
   • Cache memory is more expensive than RAM but it is a lot faster and it can store frequently-used instructions

4. Clock Speed

   • This is how fast the computer can process instructions
   • The higher the Clock Speed, the faster the computer is
   • Clock Speed is measured in hertz (1Hz = 1 cycle per second, 1GHz = 1,000,000,000 cycles per second)
