Heya ;
here's is your answer you are looking for ;
***Main memory***
*The main memory of the computer is also known as RAM, standing for Random Access Memory. It is constructed from integrated circuits and needs to have electrical power in order to maintain its information. When power is lost, the information is lost too! It can be directly accessed by the CPU. The access time to read or write any particular byte are independent of whereabouts in the memory that byte is, and currently is approximately 50 nanoseconds (a thousand millionth of a second). This is broadly comparable with the speed at which the CPU will need to access data*
Hope this will be helpful for you. (^^)
thank you..

Main memory is also known as RAM.
RAM is an electronic, or volatile, state. When the computer is off, RAM is empty; when it is on, RAM is capable of receiving and holding a copy of the software instructions and data necessary for processing. The Ram is used for the following purposes:
• Storage of a copy of the main systems program that controls the general operation of the computer. This copy is loaded into RAM when the computer is turn on; it stays there as long as the computer is on.
• Temporary storage of a copy of applicationprogram instructions to be retrieved by the central processing unit (CPU) for interpretation and execution.
• Temporary storage of data that has been input from the keyboard or other input device until instructions call for the data to be transferred into the CPU for processing.
• Temporary storage of data that has beenproduced as a result of processing until instructions call for the data to be used again in subsequent processing or to be transferred to an output device such as the screen, a printer, or a disk storage device.
• RAM chips are often called dynamic RAM (DRAM) chips, based on the style of the electriccircuits.
