![]() The secondary memory (hard disk) is referred as storage not memory. Computer memory is of two types: Volatile (RAM) and Non-volatile (ROM). Each cell has a unique address which varies from 0 to memory size minus one. The computer memory is divided into large number of small parts known as cells. ![]() Both the input and the output can be held here. It is a data storage device or a data storage component where instructions for processing data are kept along with the data that has to be processed. It is the same as a human mind, where data, information, and instructions are stored. The computer memory holds the data and instructions needed to process raw data and produce output. Consequently, a computer is also referred to as a data processing system. Here, input means the unprocessed data that we want the machine to handle and then give us a response, and output refers to the outcome of the machine's processing of the unprocessed data, which may include data analysis, searching, distributing, storing, and more. After that, it provides the result according to the inputs. The data is then processed and converted into valuable information. Put in another way, the computer receives input such as data and stores it together with instructions in memory (use them when required). It has the potential to execute programmed computations quickly and with great accuracy. A computer is an electronic device that takes raw data as input and, processes it, then provides the desired result.
