Bus speedįor older computers, the bus speed of the motherboard increases the speed at which data is being transferred between all the hardware components. By adding this extra step, (and because hard drives and SSDs are the slowest types of memory), your computer can become much slower without enough memory. If your computer runs out of memory, the computer must swap unused data stored in memory to the primary storage device until it is needed again. Memory (RAM)Ī computer with more memory ( RAM) is capable of storing more programs that are currently running in memory. The cache is the fastest type of memory, and a computer with more L2 cache or 元 cache can store more instructions and send them to the processor more efficiently. Because RAM and the hard drive are slower than the CPU, computer processors and motherboards use cache to transfer data between the processor, memory, and other components. CacheĪlthough today's computers can execute billions of instructions every second, the processor is usually waiting for those instructions from the slower types of memory in the computer. Today's processors are multi-core GHz processors capable of processing over 100 billion instructions per second. For example, the first computer processor was the Intel 4004, which was only a 740 kHz processor capable of processing approximately 92,000 instructions per second. A good processor is capable of executing more instructions every second, hence, increased speed. 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).
