What is a laptop?
A laptop, sometimes called a notebook computer by manufacturers, is a battery- or AC-powered personal computer (PC) smaller than a briefcase. A laptop can be easily transported and used in temporary spaces such as on airplanes, in libraries, temporary offices and at meetings.
A laptop can be turned into a desktop computer with a docking station, which is a hardware frame that supplies connections for peripheral input/output devices such as a monitor, keyboard and printer.

Types of laptops
Differences in these core components are what distinguish laptop computers. Some core characteristics of laptops are the following:
Size.
Screen resolution.
Higher resolution liquid crystal display or LCD screens display sharper graphics and increase the usable viewing area. High pixel density displays are becoming increasingly popular.
Processing power.
Laptop processors have two, four or eight cores and, because of that, vary in performance.
Memory.
Typically, laptop random access memory (RAM) is 4, 8 or 16 GB. The most common RAM is 8 GB, and memory is often soldered to the motherboard.
Input.
Laptops often have a built-in microphone, video camera and various input ports, such as Lightning, HDMI and USB ports. Some companies have gradually reduced the number of ports on the laptop body. Laptops use several different approaches for integrating a mouse into the keyboard, including touch pads, trackballs and pointing sticks.
Durability.
Laptops vary in durability; some are designed for use in rugged conditions.
Design.
Laptop designs and accompanying marketing terms vary. Notebooks, netbooks and subnotebook types denote different laptop sizes. New laptops, such as hybrid and convertible ones, feature displays that detach from the computer and function as touchscreen tablets.
Accessories.
Various laptop accessories -- such as a detachable keyboard or a second touchpad -- can influence purchasing decisions.
Battery life.
Laptops are battery-powered, as well as having power adapters to plug into a power source. Batteries vary among laptops, and battery life can also influence buyers.
