Basics of Information Technology

Software its types and Programing Languages SOFTWARE             Software is a program to issue some instructions to the computer hardware to get the desired results. Computer Hardware only understands binary language i.e. 0 and 1.   Digital signals are used to make communication possible and to accomplish some tasks from the computer hardware. Software tells the program what to do. The hardware operates under the control of given set of instructions.   Software is developed in computer programming language.             Software is a program, set of functions, functions are set of instructions, and we write some instructions with the help of programming languages. i.e. C, C++, Java, Visual Basic 6.0, Visual Basic Dot Net, Visual C++. 1.       Logical part of the computer is called software. 2.       Intangible part of the computer ...

               We use a term GIGO for computer, Garbage In Garbage Out. It means that the output of the computer depends upon the input. Out put of the computer depends upon the input data and instructions given to it.                  We categorize hardware into to categories input devices and output devices.   INPUT             We use computer simply for some kind of calculations. For calculations we require some instructions given to the computer hardware to execute the desired task. The instructions given to the computer hardware are considered as input.   INPUT DEVICES             The devices that are used to enter data and instruction into the computer are called input devices. The input device is a hardware component. It takes input (data or instruction) from user...

Introduction to Computer Hardware and Software PLATFORM             The word computer is derived from compute. Compute is a Latin word. If means that the combinations of many things. So we refer computer as the combination of different thing i.e. Hardware and software. Platform means the combination of hardware and software. We simply divide platform into two different categories:- 1.                   Hardware 2.                   Software COMPUTER             Computer is an electronic device. It is used to solve problems according to a set of instructions given to it. It solves a problem by dividing it into extremely simple steps. It uses electronic pulses to execute instruction. Computer is also con...
