 A computer is an electronic data processing device, which accepts and stores data input, processes the data input, and generates the output in a required format. Hardware Hardware represents the physical and tangible components of a computer, i.e. the components that can be seen and touched. Examples of Hardware are the following − Input devices − keyboard, mouse, etc. Output devices − printer, monitor, etc. Secondary storage devices − Hard disk, CD, DVD, etc. Internal components − CPU, motherboard, RAM, etc. Software Software is a set of instructions that make the computer perform tasks. In other words, software tells the computer what to do. Though the array of available programs is vast and varied, most software fall into two major categories; system software and application software. 1. System Software System software is a program that control the computers hardware or that can be used to maintain the computer in some way that it can run efficiently. There are three basic types of

  Basics of computer Architecture The computer system hardware comprises of three main components — 1. Input/Output (I/O) Unit, 2. Central Processing Unit (CPU), and 3. Memory Unit. The I/O unit consists of the input unit and the output unit. CPU performs calculations and processing on the input data, to generate the output. The memory unit is used to store the data, the instructions and the output information. Figure below illustrates the typical interaction among the different components of the computer. I.Input/Output Unit  The user interacts with the computer via the I/O unit. The Input unit accepts data from the user and the Output unit provides the processed data i.e. the information to the user. The Input unit converts the data that it accepts from the user, into a form that is understandable by the computer. Similarly, the Output unit provides the output in a form that is understandable by the user. The input is provided to the computer using input devices like keyboard, mouse

Programming Languages A Programming Language consists of a set of vocabulary and grammatical rules, to express the computations and tasks that the computer has to perform. Programming languages are used to write a program, which controls the behavior of computer, codify the algorithms precisely, or enables the human-computer interface. Each language has a unique set of keywords (words that it understands) and a special syntax for organizing program instructions.  The programming language should be understood, both by the programmer (who is writing the program) and the computer. A computer understands the language of 0∙s and 1∙s, while the programmer is more comfortable with English-like language. Programming Language usually refers to high-level languages like COBOL, BASIC, FORTRAN,BCPL, C, C++, Java,Python etc. High level programming language is chosen depending on the type of the application you are going to develop.For example if we are developing android mobile applications we use
