In computer terminology, memory and storage are the two most important components involving computers storage system where everything happens. The primary memory stores instructions. RAM. Primary Storage ROM • This memory is used as the computer begins to boot up. Molecular memory stores information in polymer that can store electric charge. Primary Memory also called as volatile memory because the memory can’t store the data permanently. This GATE exam includes questions from previous year GATE papers. Questions from Previous year GATE question papers, UGC NET Previous year questions and practice sets. Memory is sometimes called primary memory. It is used to hold/store data and applications temporarily or for a shorter period of time while the computer is running. The main features of primary memory, which distinguish it from secondary memory are − It is accessed directly by the processor; It is the fastest memory available; Each word is stored as well as; It is volatile, i.e. This is because of “iconic memory,” the visual sensory store. Types of Primary Memory 1) RAM, 2) ROM. It also has another name i.e. Secondary storage devices are volatile in nature, it means that data does not discard while power turn-off, in which all data store for long time.Secondary memory has the speed of access of data is very slow compare to primary memory, and cheaper as well. Main Memory: It is the one that is responsible for operating the data that is available by the storage medium. For example, a word which is seen (in a book) may be stored if it is changed (encoded) into a sound or a meaning (i.e. It stores data for temporary use. Where is the headquarters of Intel located. Primary memory is considered as a main memory that is accessed directly by the computer, so as to store and retrieve information. The capacity of RAM in terms of data storage is less, but it offers a very fast access rate, thus making it pretty expensive.
