Computer Performance

1. Cache

   • Cache is a temporary storage area that has copies of data, this is volatile
   • Cache is used in the CPU (Central Processing Unit) in a computer to access data from the main memory
   • Cache is used because main storage can't keep up with all the demands of cache

2. RAM

   • RAM (Random Access Memory) is a type of computer storage that can be accessed randomly
   • RAM is the memory in a computer that is used to store running programs for the program
   • RAM is the hardware in a computer that when data is being used is kept so they can quickly be reached

3. Cores

   • A core processor is a chip with independent units called cores
   • Cores are parts of the CPU that receives instructions and performs calculations
   • The CPU has multiple cores and if you have a 2 cores it will be called a dual-core

4. Clock Speed

   • The clock speed in a CPU is measured in hertz generally in gigahertz
   • The speed is measured in gigahertz which is the speed of a single core of your processors
   • The CPU requires a fixed amount of clock ticks or clock cycles to execute each individual instruction
