Computer Performance

Computer Performance

1. Cores

   • WHY If you have more cores , the CPU can carry out even more instructions in the same period of time.
   • HOW Getting a dual core processor would enable the CPU to fetch and execute two instructions in the same time it takes a single core processor , therefore it will be faster
   • WHAT Cores manipulate how many fetch decode execute cycles can be done/ second

2. Clock speed

   • WHAT How many cycles a CPU can do in a second (measured in Hz)
   • WHY increasing the clock speed will mean that the computer works more effectively and faster
   • HOW you could get a processor with a faster clock speed

3. Cache

   • WHY The bigger the cache is, the more quickly the commonly used instructions and data can be brought into the processor and used.
   • WHAT memory built right onto the processor. The most commonly used instructions and data are stored in the cache so that they are close at hand.
   • HOW if you upgrade to more cache , you will have more space in cache and will need to use less of RAM

4. RAM

   • WHAT main storage of data that is currently in use ; it is only temporary or volatile meaning the data is not stored when the computer switches off
   • WHY increased amounts of RAM will enable the device to store more data
   • HOW you can get larger amounts of RAM so that you don't need to resort to virtual memory
