A laptop computer (also shortened to just laptop; or called a notebook computer) is a small, portable personal computer (PC) with a “clamshell” form factor, typically having a thin LCD or LED computer screen mounted on the inside of the upper lid of the clamshell and an alphanumeric keyboard on the inside of the lower lid. The clamshell is opened up to use the computer. Laptops are folded shut for transportation, and thus are suitable for mobile use. Its name comes from lap, as it was deemed to be placed on a person’s lap when being used. Although originally there was a distinction between laptops and notebooks (the former being bigger and heavier than the latter), as of 2014, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, for playing games, Internet surfing, for personal multimedia, and general home computer use.
Laptops are computers that you can take everywhere with you without hassle. They can take up very little space and be used for hours without access to power. Laptops come in various sizes, which usually refer to the size of the display. They range from a 10-inch to a 20-inch for mainstream laptops. Their weight ranges from a couple of pounds to over 9lbs. Besides size display, laptops come in various resolutions ranging from 1280×800 to 1920×1080. The display also comes with glossy and matte coating and energy-saving features. Laptop hard drives are smaller than desktop hard drives and are available in three speeds, depending on the energy savings and performance such as 4500, 5400, and 7200 RPMs (rotations per minute). Laptop processors and video cards are designed based on the desktop processors, but are created with low power in mind. They are usually less powerful than the desktop computer. Battery life will depend on the battery capacity noted in watts per hour and the laptop power consumption. Laptop battery life varies greatly from under one hour for gaming laptops to over 10-hours for small laptops.
