Sony VPCZ21DGX Ram
Random Access Memory, RAM, stores small bits of data that the processor uses for applications. The Sony VPCZ21DGX will not boot without the necessary RAM properly installed. Because RAM is only temporary storage for the CPU, it does not hold files like text documents or movies. But, it will affect the speed of your Sony VPCZ21DGX. The clock speed of the RAM is dictated by the specifications from the motherboard, while the size is guided by the system software. RAM is considered volatile memory as all the information held gets removed when you shut down your system. If there is ever a doubt, just be sure to remember that you can never have too much RAM in your system.
