Computer Performance

1. Cache

   • a cache is a temporary storage area that has copies of data that is used often.
   • Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU
   • Cache is used because bulk, or main, storage can't keep up with the demands of the cache clients. Cache shortens data access times, reduces latency and improves input/output

2. Clock Speed

   • The number of fetch decode and execute cycles a CPU can perform p/s
     • This will help because it will make the computer faster
   • 1Hz is 1 cycle 1GHz is 1000 and so on

3. RAM

   • Stores the program, parts of the operating system and the files currently being used.
   • RAM is a Volatile meaning that data is not stored when switched off
   • RAM is essentially the core of your computer. ... The more RAM your CPU has access to, the easier its job becomes, which enables a faster computer.

4. Cores

   • The number of independent processors in the CPU
   • They work simultaneously
   • Quad-core processor is a chip with four independent units called cores that read and execute central processing unit (CPU) instructions such as add, move data, and branch. Within the chip, each core operates in conjunction with other circuits such as cache, memory management, and input/output
