Computer Performance

1. RAM

   • RAM is the computers memory the more RAM you have the more you can store on your device computers
   • Srores the programs (Apps) this means that the more RAM you have the more apps you can download and store
   • RAM is volatile meaning that the data is not stored when the computer system is switched off this means that anything opened or unsaved when the device is shut off it will be manully deleted

2. Cores

3. Clock speed

   • 1Hz = 1 cycle per second, 1KHz = 1000 (thousand) cycles per second, 1Mhz = 1,000,000 (million) cycles per second, 1GHz = 1,000,000,000 (Billion) cycles per second
   • Clock Speed is the number of fetch decode execute cycles a CPU can perform per second. This is measured in hertz (Hz)
   • The faster your clock speed is the faster your Fetch, decode, execute cycles are done (per second this means that the faster the Clock speed is the faster the instructions to the CPU are made and done.

4. Cache

   • Cache is memory in the CPU which is used to store frequently used data.
   • The more Cache you have the more memory that can be stored on the CPU.
   • Used for high speed static
