![]() RAM or Random-Access Memory is used to store temporary data. Types of MemoryĪll the different memories on a computer system can be categorised in to just two types of memory. In case of a typical Write operation, it needs an address at which the data must be stored and the actual data itself. A typical Read operation on memory needs an address as input and returns the data at that location. There are only two basic which you can perform on a Memory. A Byte of data can have any binary value between 0000001111. It represents logical state with help of one of two possible values ‘1’ or ‘0’.īyte: A group of 8-bits is called a Byte. Two of the common units of information are listed below:īit: The smallest unit of Data. By combining 8 of these bits, we get a Byte, which can 2 8 = 256 different bit patterns. This is known a Bit, which is the smallest unit of data in Digital World. So, the state of a signal can be either ‘1’ or ‘0’ at any given time. For example, in a 5V Logic Level System, ‘1’ represents 5V and ‘0’ represents 0V. This is used to represent the voltage level of the signal. We know that Digital Electronics deals with only two numbers 1 and 0. Irrespective of the size and application i.e., it can be a huge storage server or a simple microcontroller based embedded system, all computer systems require memory. This is called Memory.Ī Computer Memory is an electronic device that stores data and instructions either permanently or temporarily. Produce the result (data) with the help of some output devices.įor the processor to do these operations seamlessly, it needs to store the input data, hold the intermediate results and also store the output data (results) at some place.Accept the data with the help of some input devices.All these complex tasks can be boiled down to just three basic operations: ![]() Computers are designed and developed to perform various engineering, mathematical, educational and entertainment tasks at very high speed and with great accuracy.
