What are the importance of computers?

Computers are very important in the fast paced world we live in today. Most likely in the future technology will improve. It could probably improve to the point where we will be able to clone humans, and build high tech robots to be able to do what we want them to do. I would say technology has improved since the past because just years ago we couldn't even use the internet that we have today. Back then we were lucky if there was one simple program that our computer can hold today we can pretty much have as many programs as we could possibly want on our computer because we can just purchase more memory. For example Flashdrives they can come in 64 mb to 1 or even 2 tb. Technolgy has made a lot of improvement within the last 30 years and im sure within the next 30 years it will make even more improvements.

Why are computers so popular?

Computers are very popular because they let us view information without having to travel to sources for example the library, or or a certain place. It also lets us buy things at the click of a button where they can ship it right to their house without them even have to go to the store to get it. Making everything easier for really busy people.
