Sony VPCZ21SHX Ram
RAM is crucial for your laptop to run correctly. Because RAM is only temporary storage for the processor, it does not hold files like text documents or movies. But, it will affect the speed of your Sony VPCZ21SHX. The RAM speed is predetermined through the specs of the motherboard, while the size is dictated by the software. The RAM in your computer stores pieces of information that the CPU is currently using for applications. Random Access Memory is considered temporary storage as the data it holds is blanked out every time your turn the computer off. If you are unsure about the size of the RAM to buy, just know that more RAM is a lot better than less RAM!
