Today 5 year old children are able to use computer while 30 years ago scientist were the only one able to use these complicated machines. This is basically being Computer literate, where an individual has the basic knowledge and understanding of computers and their uses. Computer fluency, however, is more in depth than just having basic computer knowledge. The main two and most important part of a computer is the hardware and software. What exactly is the Hardware? This part of the computer is composed of the electronic and mechanical aspects of a computer which includes printers, scanners, monitors, and speakers. The software and the other hand is like the brain and processing areas of a computer which involves running  programs and the instructing the computer how to do different things and hot to run properly.

IBM was the leading manufacture of computer during this era. Then there were the middle ages of the computer world. Here marked when more programming languages came and smaller. Now, computer chips were beginning to show up everywhere, including watches, cars, and microwaves.  This era last until early 1990, which was then after became to be the Present age of computers, which need not explanation and can be see in our everyday world and is a necessity in our lives. Through so many changes of computer we can se how far this great machine have come, can't imagine what computers will be doing for us in the near future.
