TalentJR apps
An operating system is the main software of a computer. It starts working as soon as the computer starts, shows the desktop, manages all the files, shares memory among apps, talks to devices like the printer and runs every other program. Apps (application software) do one task for us: a word processor for typing, a paint program for drawing, a web browser for websites, a spreadsheet for number tables.
