Factors Affecting Processing Speed:

 Factors  Affecting Speed:

                                                     The important factors that affect that processing speed of a computer are as follows:

Registers:

                       Register is a small, high-speed memory inside a CPU. CPU contains a number of registers. Register store data and instructions while the CPU processes them. The size of the register determines the amount of data with which the computer can work at one time. It is also called word size.

     The size of registers is in bytes. A register can be of one, two, four or eight bytes. Computer with 32-bit registers means the CPU can process four bytes of data at one time. A bigger size of register increases the performance of the computer.

RAM:

               The amount of RAM directly affect the processing speed of the computer. Bigger amount of RAM means that more program instructions and data can be stored in memory. If a computer does not have enough memory to run a program, it must have move data between RAM and the hard disk frequently. This process is called swapping that can greatly slow a computers  performance.

System Clock:

                              System clock is an electronic component. It generate electric signals at a fast speed. It control all functions of the computer using clock tricks. These ticks of system clock are known as clock cycle and set the speed of CPU. The sped at which the CPU executes instructions is called clock speed or clock rate.

             The power of a CPU is determined by the speed at which is processes data. System clock is one of the major factors that affect a computer speed. A CPU that has a higher clock speed can process more instructions per affect a computer speed. For example, Core i7 processor running at 3.2 GHz will be faster than Core i7 processor running at 2.66 GHz if all other components remain the same. Today faster CPU have clock speed of more than 3 GHz.

  

Buses:

                A bus is a path between the components of a computer. Data and instructions travel along these paths. The bus width determines how many bit can be transmitted between the CPU and other devices. Bus width also affect the performance of the computer.

Cache Memory:

                                    A cache (pronounced "cash") is high speed memory that holds the most recent the data and instructions that have been loaded by the CPU. It is size the speed up the transfer of data and instructions Cache is located directly on the CPU and RAM. It is faster than RAM.

       The data and instructions are retrieved from RAM when CPU uses them for the first time. A copy of that data or instructions is stored in the cache. The next time the CPU needs that data or instructions, it first looks in cache. If the required data is found there, it is retrieved from cache memory instead of main memory. It speed up the working of CPU . The amount of cache memory has a tremendous impact on the computer speed.
