Both hardware and operating systems are called platforms. Programs, which are also called applications.
Use this platform to perform tasks. There are many types of programs. With some programs, you can do things like write letters, do calculations, or send e-mail messages.
For example, a word processor, such as Microsoft Office Word 2007, is a program that helps you create letters. With other programs, you can create illustrations and play games.
You can watch movies or communicate with other computer users.
Programs process the data provided as input to the computer. Data can be in the form of text, graphics, audio, or video, depending on the type of program.
For example, a calculator is a program that requires input in the form of numbers. Similarly, a sound recorder is a program that requires input in the form of audio.
When a program receives data, it operates on the data and displays the output on the screen.
You can save this output in a file, depending on the type of data kept in the file. That file is categorised as an audio file, a text file, a graphic file, or a video file.
