Computer Performance

1. cache

   • 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 instructions can be accessed quickly which will improve the performance of the computer
   • What: cache memory is faster and more expensive then RAM
   • What: cache memory stores frequently-used instructions
   • What: cache memory is a small amount of memory which is either inside the CPU closer to the CPU then RAM
   • What: is there is a larger amount of cache memory storage, a grater number of frequently-used instructions can be stored. that means that more instructions can be accessed quickly which will improve the performance of the computer

2. cores

   • How: if there is more cores then it will increase the performance
   • What: the number of independent processors in the CPU which run the fetch decode execute cycle simultaneously

3. RAM

   • What: it is were all the important information is stored
   • How: the grater amount of RAM the more instructions and data can be stored while a program is running. this means that less instructions will be stored in much slower virtual memory and therefor improve the performance of the computer

4. clock speed

   • How: it goes faster because there is more speed processing it
   • What: the number of fetch decode execute cycles a CPU can perform per second

5. virtual memory

   • What: virtual memory is used when RAM is full
   • What: part of secondary storage is used for virtual memory
