Why is the width of the data bus so important to the processing speed of a computer?
The wider it is, the greater the computer's processing speed is the width of the data bus so important to the processing speed of a computer.
The overall speed or clock speed of the computer and how fast it is capable of processing data is managed by the computer processor (CPU). The computer will be much faster and more powerful when it is capable of executing more instructions every second.
A computer with more memory (RAM) will be capable of storing more programs that are currently running in memory. If your computer runs out of memory, the computer must swap unused data stored in memory to your hard disk drive until it is needed again. By adding this extra step and because the hard drive is the slowest type of memory, your computer can become much slower if it does not have enough memory.
