Computer Performance

Computer Performance

1. Cores

   • What
     • A CPU can have more than one core.
     • It receives data/instructions and performs calculations, operations to carry out those instructions.
   • How
     • If there are more cores, the CPU will execute more instructions every second, so the computers performance will be inproved

2. RAM

   • What
     • The RAM is a form of computer memory that stands Random Access Memory
     • The RAM is volatile, this means that the data is lost when the power is switched off
   • How
     • The RAM is a part of Fetch-Decode-Execute cycle. This is where the CPU fetches the information

3. Clock Speed

   • What
     • The clock speed is the operating speed of the computer
     • The clock speed is measured in hertz.
   • How
     • The higher the clock speed, the more instructions can be executed per second so the performance of the computer will be improved

4. Cache

   • What
     • Cache memory is a small amount of memory which is either inside the CPU or closer to teh CPU than RAM
     • Cache memory is faster and more expensive than RAM
   • How
     • If there is a larger amount of cache memory storage, a greater number of frequently-used instructions can be stored. This means that more instructons can be accessed quickly which will improve the performance of the computer
