            What is Computer Memory? Those unit that provides an area for the processors or any other devices is called memory unit. It is used to store data ,instructions and Information.   Memory unit is the hardware parts of computer. It stores the data or information Temporary or permanently.  How many types of Computer Memory? There are two types of Compute r Memory. 1. Primary Memory  2. Secondary Memory    What is  Primary Memory? Primary memory is the only type memory that is directly accessed by the CPU. from 1954. Magnetic core memory became the dominate technology to we used as primary memory of computers. After that RAM is used as primary Memory. It is the firstly memory that stores the data and instructions. There are two types of Primary Memory.   RAM,(Random Access Memory)  ROM(Read only Memory)         What is  RAM(Random Access Memory) RAM is a volatile storage area withi...

            Basic Fundamental of Computer.                        What is computer? The word 'Computer' comes from the word 'Compute ',Which means 'to count' or 'to calculate ' . A Computer is an electronic device that takes input from user , process the data and gives the desired result (output). It performs both mathematical and non-mathematical operations.  It follows the principle of GIGO -Garbage In, Garbage Out (If wrong input is given, output will also be wrong).             Characteristics of Computer  1. Speed :-   Computers works very fast.  It can perform millions or billions of instructions in just one second.  What takes humans hours can be done by a computer in seconds or milliseconds. Example: Solving 10,000 math problems in a few seconds. 2.  Accuracy:  A computer is highly accurate. It gives correct results if t...

                            What is  COMPUTER LANGUAGE? ▪︎ A Computer language is the mean by which instructions and data are transmitted to the computer. ▪︎ In other words, computer languages are the interface between a computer and its user .         Categories of Computer Language. The Computer Language can be classified into four categories: 1. First Generation Language (Machine Language) 2. Second Generation Language (Assembly Language) 3. Third Generation Language (High Level Language) 4. Fourth Generation Language (Modern Language   First Generation Language(  Machine Language):- ▪︎ It is the only language that a computer can understand. It is expressed in binary form i.e. '0' and '1'.  ▪︎ Machine Language has the advantage of very high speed and very low memory utilization. But understanding and learning machine language is a tough and tiresome process.  ▪︎ This lan...
