For decades, computers have taken over the roles once held only by humans. Nowadays, computers power our homes, control traffic lights, automate factories and even fly spaceships and nuclear submarines. Will humans eventually become obsolete? Here is an article about things a computer can do.

Connect to the Internet

You can connect a PC and a printer, but that doesn’t make them work together very well. They don’t even talk to each other. If you want to use your computer to print something out, or vice versa, it needs some help. The most common way to do this is through what’s called a _network_, which connects all of the devices on one computer network so they can communicate with each other and with computers outside the home.

 A network will also let you share files among different networks on the same local area network (LAN) or wide-area network (WAN), such as the public Internet. You might have heard people say things like “connecting directly” when they mean connecting through a router or gateway; for example, if you are connected to the Internet by cable modem, then you’re directly connected to the Internet, not through a router visit for more information.

Use your word processor

If you’re writing documents, use your word processing program. Word processor programs aren’t just limited to letters, though: They’re used for creating everything from reports and essays to business plans. Many professionals think about word processors as their primary tool for getting stuff done. That’s because a lot of the time they contain tools for formatting text, tables, graphics, charts, lists, and more.

A Computer Broaden Your Knowledge

While it isn’t essential to be an expert at any particular technology, being able to operate every piece of equipment in your house is pretty important. To learn how to turn on an appliance, open up a file, read a spreadsheet, play a game, watch a video—everything! This is especially true if you’ll be working with someone who knows nothing about the technology you’re using. Asking questions, showing interest, and explaining why you’re doing certain tasks makes it easier for others to understand.

With a Computer, you Can Download or Copy Sound Files

Before the advent of digital music players, there were two ways to take sound recordings along with you. You could either buy a cassette tape player (which recorded onto magnetic tape) or copy them onto compact discs (CDs). Although both methods worked fine, they had drawbacks. Cassettes tended to wear out quickly, and CDs needed special equipment to transfer files into your computer.


Technology has changed significantly over the centuries since the printing press was invented by Johannes Gutenberg. While we no longer have books printed on paper, almost every aspect of our lives today depends on computers. Without them, you wouldn’t get online, listen to audio or videos, read ebooks, or watch movies.
