Other than the CPU and motherboard, the RAM (Random Access Memory is the next most important hardware in your system.
When a computer first boots up, the system loads data from the hard drive into the RAM. At any point of time when the CPU needs any information, it will access the RAM to retrieve the data it needs. Since the RAM transfer data at a speed faster than any other storage media (such as the hard drive, CD-ROM and floppy disk), the retrieval process is shorter, work gets done faster and hence the computer performs better.
