To read the data present in this buffer, we have at our disposal a set of instructions in algorithmic language according to the type of data we want to read: Instruction Below is an example of the buffer content as keyboard keys are being pressed: Pressed key

This buffer is a structure known as FIFO (First In First Out), which means that the oldest entry will always be read first. Keep in mind that the line break also counts as any other key and is usually represented by '\n'. The data reading methods will be reading from this buffer considering what type of information we are trying to read. The buffer contains the entire character sequence typed by the keys that no program has read yet.

The first thing we need to know is that when keys are pressed on a keyboard, what is written is converted into ASCII code and stored as characters in a buffer. In this guide we will see how we can communicate with these devices to read information from the keyboard and display it on the screen. In fact, if it is not explicitly changed, the standard input (or stdin, which is short for standard input) is the keyboard, and the standard output (or stdout, which is short for standard output) is the screen. Among all these devices, two have a particularly relevant role: the keyboard for data input and the screen for data output. Likewise, output may refer to a wide range of things, be it a computer screen, a file, a printer or the control system of a robot. When we talk about data input we mean any type of input they can be the keys that are pressed on a keyboard, the position of a mouse or a touch on a touchscreen, a disk file, an internet address, a barcode reader, a webcam or a microphone. Without an input programs would always do the same with the same data and, if we do not have output, the results of the program could never be used. Therefore, programs need to get this information to be able to process it and output the results.
