History of the Laptop:

A small laptop, also recognized as a notebook computer (or simply a notebook) is a small-sized personal computer. A laptop naturally weighs from one to three kilograms depending on size and other factors.

The term “laptop” was innovated in 1983 with the Gavilan SC. The term “notebook computer” was used to distinguish smaller computers such as the Compaq LTE series of 1989. Now, the terms can be used interchangeably.

However, both terms have been used inappropriately, because most laptops were unsuitable to use on one’s lap due to heat and other issues. And, some older portable computers, like the Macintosh Portable, were described as “laptops,” but their size and weight were too great to properly fit in this category.

Laptops usually run on a single battery or from an AC/DC adapter, which charges the battery while supplying power to the computer. Moreover, laptops typically have liquid crystal displays (LCD) and use different memory modules for their RAMS. They have a built-in keyboard, with a touchpad (track pad), although a mouse is typically attached.

Different Types of Laptops

Ultra portables—Laptops, which are very portable with screens less than 12 inches diagonally, and weigh less than 1.7kg are famous as ultra portables. There laptops are typically used by business people who require small, light computers for travel. These laptops are usually very costly due to their convenience.

Medium-sized Laptops—These laptops have screens of 15 to 15.4 inches diagonally and weigh just about 3 to 3.5 kg.

Desktop Replacement Computers—These are powerful laptops used mostly in a fixed place and are not usually moved because they can be fairly large and heavy. There screen size measures 15 inches or more. Their battery life is frequently limited to three hours because their hardware is not planned for power efficiency.
