Laptop memory

it is used most often to identify fast, temporary forms of storage. If your laptop's CPU had to constantly access the hard drive to retrieve every piece of data it needs, it would operate very slowly. When the information is kept in memory, the CPU can access it much more quickly. Most forms of memory are intended to store data temporarily.

 

 The CPU accesses memory according to a distinct hierarchy. Whether it comes from permanent storage (the hard drive) or input (the keyboard), most data goes in random access memory (RAM) first. Types of memory Read-only memory (ROM) ROM is non-volatile, meaning it holds data even when the power is ON or OFF. Random access memory (RAM) RAM is volatile, meaning it holds data only when the power is ON (only while the laptop is running). When the power is OFF, RAM's contents are lost.

Some laptop had RAM installed in the motherboard as individual chips
