IntroductionThe word "computer" is very famous among all of us nowadays. Almost each of us owned our own personal computer. In fact, a portable personal computer or also known as laptop was introduced to the world by Adam Osborne in 1981. Most of the people prefer to use laptop because it is easy to carry wherever you go.

Since then, they've made it even thinner, lighter, and even smaller. I myself have been using computers since I was 10 years old and I can see a great transformation in terms of creation and technology. What is computer?

I actually have an experience where I have no idea how to refill ink for inkjet printer. I am very lucky because the printing house already existed during my primary school year. The evolution of the printer in terms of technology has grown so rapidly. The same goes for the keyboard. Nowadays, they are also touchscreen keyboards. I'm really fascinated by the growth of this computer hardware.
