![]() ![]() Non-volatile memory stores information even when there is a power supply failed/ interrupted/stopped. (ii) ROM (Read Only Memory): It is a non-volatile memory. It needs refreshing of charge on capacitor after a few milliseconds. D RAM (Dynamic RAM): It uses capacitors and transistors and stores the data as a charge on the capacitors.It has less access time and hence, it is faster. This memory consists of the number of flip flops with each flip flop storing 1 bit. S RAM (Static RAM): It uses transistors and the circuits of this memory are capable of retaining their state as long as the power is applied. ![]() It can store both the input and output can be stored here. It is a data storage unit or a data storage device where data is to be processed and instructions required for processing are stored. It is used to store data/information and instructions. What is Memory?Ĭomputer memory is just like the human brain. Thus, we can also call a computer data processing system. Here, input refers to the raw data that we want the machine to process and return to us as a result, o utput refers to the response that the machine provides in response to the raw data entered and the processing of data may involve analyzing, searching, distributing, storing data, etc. It then processes the data and converts it into useful information. Or in other words, the computer takes data as input and stores the data/instructions in the memory (use them when required). It performs programmed computation with great accuracy & higher speed.
