These are programs that are integrated into the operating system. That is, they do not need to be installed, they are already in your computer from the first time it is started.
Notepad
This is a simple text editor. You can use it to enter text, edit it, and save it on your computer. All text files created by Notepad have the ".txt" extension. If you change the font or character size - it changes in the whole file. You cannot change the style of individual characters. Documents created in Notepad take up very little space on your computer.
If you put the code sequence ".LOG" in the topmost line of the program and save it, the current date and time are added to the file after opening it.
This program is mainly used as a day planner. More advanced users can write special commands into the notepad and use it to make a simple web page, or write simple programs.
Calculator
