Computer Performance

Computer Performance

1. Cores

   • You would want multiple cores because then your computer would be able to multitask faster.
     • Your device would need the specification for software not to be met.
   • The core allows the device to run applications simultaneously. You can have quad cores, dual cores and so on but they're all individual processors.
   • It improves the performance by allowing multiple applications/instructions to run at the same time.

2. RAM

   • RAM (Random Accessed Memory) stores the programs, parts of the operating system and the files currently being used.
   • More programs can be opened at the same time.
   • Virtual Memory is used when RAM is full. By increasing the RAM, virtual memory is not relied on as much so more programs can be open at once.

3. Clock Speed

   • Clock speed is how many fetch,decode and execute cycles can run per second. It's measured in hertz (Hz): 1GHz= 1,000,000,000 cycles per second.
   • Clock speed makes your programs run faster so you'll be able to access your programs quicker.
   • Programs will run faster as more instructions can run per second.

4. Cache

   • Cache stores frequently accessed instructions in your computer.
   • It would make your frequently used programs load faster.
   • Recently used data can be accessed quicker.

5. Solid State

   • Solid state uses microchips to store data instead of magnetised disks and does not contain any moving parts.
   • Programs and data will load faster.
   • By having a solid state hard drive,
