1. Clock speed

   • The number of fetch decode execute cycles a CPU can perform per second. This is measured in hertz (Hz).

2. Cores

   • The number of independent processors in the CPU which run the fetch decode execute cycle simultaneously.
     • Simultaneously: At the same time.
   • Quad core: 4 independent processors in the CPU working simultaneously.
   • Dual core: 2 independent processors in the CPU working simultaneously.

3. Virtual memory

4. RAM

   • The purpose of the RAM is to store all of the programs and data the computer system is currently using.
   • Having more RAM in your computer system will mean that More programs and data can be opened and used at the same time on the computer system.
   • RAM is volatile, meaning that the data is not stored when the computer system is switched off.

5. Secondary storage

   • Solid State
     • Lower capacity than magnetic
     • Faster Read/Write speed than magnetic
       • Portable
     • Used in portable devices because if you drop it, as it has no moving parts,it will be less likely to break
   • Magnetic Storage
     • Slow Read/write speed
     • High capacity
   • Optical Storage
     • Not durable
     • Portable
   • Non volatile
