what are laptops

By Alex Gerovski


Laptops has been around since around the early 90's. The desktop which bought computing into our rooms had not been mobile. You could not deploy a desktop outdoors because it needed a wall socket for power source and also the big cathode ray tube screen and tower were way too heavy to lug around.

For this reason there was clearly an excuse for a new generation of computers which are compact and mobile. A computer that can be easily carried along and used anywhere you intend to. Thus the laptop was invented to satisfy this need in the computer market. Alan Kay was the initial person to envision a laptop in the 1970's. The first laptops appeared in Australia in 1981 but were not commercially marketed until 1984.

The laptop was developed to replace desktops in most areas and it has actually gone on to replace it. A laptop are able to do all that a desktop can and you could carry it within your backpack and go along with you. A laptop includes a screen, keyboard and a track pad rather than a mouse. However the kind of a laptop was made its popular, a laptop can fold much like a notebook and occupy minimal space. There is no need a tower like in a desktop as the motherboard, hard drive and optical drive is right under the keyboard and therefore doesn't require extra space.

A laptop is actually mobile due to the fact it does not depend upon the wall socket for power regularly. It has a battery pack that is charged while you're using the laptop using the power adaptor which happens to be attached to the wall socket. But when the battery is charged you'll be able to carry it together with you anywhere you want to go. A typical 6 cell battery will give you not less than 5 hours of operating time.

The new generation of laptops is smaller and lighter. These come in screen size between 7 to 10 inches and therefore are also known as netbooks. The key reason why they may be called netbooks is because they were manufactured to focus on consumers who make use of the laptop to predominantly access the internet. Netbooks do not have an optical drive and a smaller battery which is why they can be lighter and can sometimes carried along.

New ultra-thin laptops are incredibly slim. These laptops can in fact squeeze into a manila envelope. Made from a particular block of aluminum these laptops may also be very durable.
