It is a piece of computer hardware where the data that your computer is currently working on is stored.
-Unlike hard drives, RAM is a volatile memory and requires power to keep the data accessible. If the computer is turned off, all data contained in RAM is lost. New users often confuse RAM with disk drive space. See [memory definition](https://www.computerhope.com/jargon/m/memory.htm) for a comparison between memory and storage.
However, there are different use-cases like virtual memory where some portion of disk is allocated for the memory to support large applications which cant fit in RAM. Also there is something called RAM-disk where a portion of RAM is allocated for disk so that the access for those disk files is very fast. +RAM stands for random access memory, alternatively referred to as **main memory**, **primary memory**, or **system memory**.
+ +This is where a PC stores data before it’s processed. A RAM DIMM (Dual Insert Memory Module) is made of up memory chips that a computer can write continiously & rapidly. RAM is a volatile form of data storage, which means that it only process and transfer data as long as it is powered on. The moment RAM is out of power is the moment the data inside RAM is erased. RAM is measured in gigabytes (GB). In contrast to other direct-access storage media such as CD & DVD or hard disks, read and write times varies significantly depending on their physical location, recording medium and media rotation and arm movement. + +RAM contains multiplexing and demultiplexing circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM devices often have multiple data lines and are said to be "8-bit" or "16-bit", etc. devices. + +RAM is associated with volatile types of memory, altough non-volatile RAM has also been developed. However, these types of RAM come with a burden. Such as not being able to write but just read. + +RAM consumes much more power than hard drives. However, as stated above the RAM you will be using in your laptop or computer is most likely a volatile memory and requires power to keep the data accessible. If the computer is powered off, all information inside RAM will be lost. +(https://www.computerhope.com/jargon/m/memory.htm) for a comparison between memory and storage.
