»How has this technological advance changed over time?

When the computer was first introduced, it was just a mechanical box that held information. But now, it has so many things you can plug into it!

You can plug a microphone into it, and process music which allows bands to make their art heard. You can plug in speakers or headphones and hear music or information played over the computer's information processor.

Having a keyboard and mouse to input information and navigate the different compartments of the computer's hard drive. There are so many changes and hardware you can use to continue changing it!

But the information you can find, also has a dangerous, and bad side to it all. By entering information into a computer and sending it across the Web, it could get intercepted half-way through, and be seen and read by someone else. An example being, a hacker.

So even though the changes of the computer have been good and definitely plenty, there are bad side-effects that occur as well.
