Hardware- These are parts that you can touch, such as the monitor, keyboard, CPU, mouse, etc.
Software- Software includes the various programs that the computer runs, as well as the Operating System; typical examples are Windows, Mac OS, and Linux.
A computer can be used for many tasks, including writing a document, sending an email, creating a spreadsheet, searching the internet, and more.
What is the Internet?
The internet is a worldwide network connecting millions of computers and devices around the globe that allows people to view the information, communicate with others, and utilize online services such as shopping, banking, and online learning.
