A notebook (notepad, writing pad, drawing pad, legal pad) is a small book or binder of paper pages, often ruled, used for purposes such as recording notes or memoranda, writing, drawing, or scrapbooking.

Notepad+ is a freeware text editor for Windows operating systems and is intended as a replacement for the Notepad editor installed by default on Windows. It has more formatting features but, like Notepad, works only with plain text. It can open text files of any size, and a single instance of the program can have multiple files open simultaneously. It supports dragging and dropping text within a file and between files, and supports multiple fonts and colours.

Notepad++ is a text editor and source code editor for use with Microsoft Windows. Unlike Notepad, the built-in Windows text editor, it supports tabbed editing, which allows working with multiple open files in a single window. The project's name comes from the C increment operator.
