A Chronology of Computer History

laptop-computer-history

Modern computer technology offers a universe of conveniences. People can look for jobs online and even work from home via the Internet, while cutting edge technology enables doctors to do surgery on people from around the world. This is due to the abundance of modern gadgets including laptops and tablets, as well as personal desktop computers, high speed Internet lines, and web hosting servers. In order to appreciate these technological wonders, however, it is important to know how technology got to this point.
