Basic Structure of Computer All types of computers follow a same basic logical structure and perform the following five basic operations for converting raw input data into information useful to their users. Following diagram shows the basic structure of Computer: Input Unit This unit contains devices with the help of which we enter data into computer. This unit makes link between user and computer. The input devices translate the information into the form understandable by computer. CPU (Central Processing Unit) CPU is considered as the brain of the computer. CPU performs all types of data processing operations. It stores data, intermediate results and instructions(program). It controls the operation of all parts of computer. CPU itself has following three components ALU(Arithmetic Logic Unit) Memory Unit Control Unit Output Unit Output unit consists of devices with the help of which we get the information from computer. This unit is a link between compu...

Concept of Hardware and Software:   Hardware: Contents: Computer hardware can be categorized as having either internal or external components. Internal components include items such as the motherboard, central processing unit (CPU), random access memory (RAM), hard drive, optical drive, heat sink, power supply, transistors, chips, graphics processing unit (GPU), and network interface card (NIC).  Thesescomponents collectively process or store the instructions delivered by the program or operating system (OS). 1 1. Internal hardware components . 1 2. External hardware components . 2 Various Examples Of Application Software Are: . 4 Utility Software . 4 Computer hardware is a collective term used to describe any of the physical components of an analog or digital computer. The term hardware distinguishes the tangible aspects of a computing device from software, which consists of written  instructions  that tell phy...

What is a language? Language is the medium of communication to share ideas, opinion with each other. For an example, if we want to communicate with someone, we need a language it may be English, Hindi, Spanish or another language. But you need at least one language to communicate with someone (human/person). What is a programming language? To communicate with a person, you need a language. Same if you need to communicate with the computer, you need a programming language. Without any programming language you cannot communicate with the computer. Thus, programming language is the medium of communication between you (a person) and a computer system. It is the set of some instructions written in a specific style (coding) to instruct the computer to do some specific task. Types of computer programming languages There are basically three types of computer programming languages, they are 1.      Low level programming languages 2.  ...
