Compaq Presario CQ42 Ram

Because RAM is only temporary storage for the processor, it does not have the ability to store files such as text documents or movies. Instead, it has a positive impact on the overall speed and quickness of your Compaq. Random Access Memory is considered volatile memory as all the information held gets blanked out when you shut down your system. Some RAM is mandatory even for your laptop to run correctly. The speed of the RAM is governed by the specifications from the motherboard, while the actual storage size is guided by the software. Random Access Memory, RAM, stores pieces of information that the processor uses for applications. If you are unsure about the size of the RAM to buy, just know that it is impossible to have too much RAM!
