File format

A file format is like a special language that computers use to talk to each other. Just like how we have different languages like English, Spanish or French to talk to each other, computers have different file formats like .docx, .mp3, .jpg and so on to communicate with each other.

So, when you create a document like a report or an essay using your computer, the computer needs to save that document in a certain file format so that other computers can understand it. For example, if you save your document in the .docx format, then it means that your document is written in a language that Microsoft Word can understand.

Different file formats are used for different types of files. For example, .mp3 is a file format used for audio files, .jpg is a file format used for image files and so on.

Using the right file format is important because it ensures that your file can be read and understood by other computers. Just like how we would struggle to understand someone speaking a language we don't know, computers wouldn't understand files that aren't in the right format. So, it's important to choose the right file format depending on the type of file you're working with.
