Laptop or notebook computers are most revolutionized and high-tech form of digital computers. Invented in 1981 by Adam Osborne, this technology actually changed the technological directions. First laptop wasn’t able to run on battery power and was heavy in size but at least it molded the concept of carrying business data and other important documents just like routine traveling luggage. This key factor led the vendors to research deeply and to introduce smart, portable, compact and faster laptops.

Practically ‘GriD Compass - 1982’, ‘Gavilan SC - 1983’ and ‘Sharp PC-5000’ are considered as first portable laptop computers characterized with plasma display, battery power and colored cases. Then IBM-Compatible laptops were introduced and other manufacturers started to produce this light weight technology. Toshiba, Compaq, Apple, ZDS, Dell and other top brands are continuously designing remarkable computer modules and smaller chips.

Now day’s laptops are available with their smallest weight, fast speed, and multi functionalities. Even one can easily find just 4 to 6 pounds notebook, 17 inches convertible display screen, core 2 due processors, transferable storage, Hi-Fi multimedia system and many other countless features. As compared to desktop computers, people (particularly business and executive class) like to use notebook computers because they can carry it anywhere. Professional and educational sector is also availing its advantages. Their prices are also cutting down to affordable and user level.

Because of tiny parts, inflexible integration and deteriorated type accessories, laptop computer’s compatibility, durability and transferability is very limited as compared to desktop computers. Although there are some manufacturing standards but every vendor is using their own technology and framework. There are very few and inadequate up-gradation facilities. Dropping, liquid spilling, or any other rough usage can make them broken and unusable. With the ability to execute for longer time, their performance and processing speed is as effective as desktop computers.
