What is a Laptop? Different Types of Laptops and Their Advantages

A laptop computer (or simply, laptop) is a portable personal computer with a clamshell form factor, meaning the components are housed in two separate parts (the screen and the base) that close on top of one another when you are working on it or storing it. A laptop is also known as an ultraportable computer because of its small size and light weight, which make it easy to transport from place to place.


Laptops are portable computers that allow you to work on the go. They are lighter than desktop computers, but some models can’t be used for gaming or other intensive applications because they may not have enough power. A laptop has three major parts: the screen, the keyboard, and the touchpad. The screen typically measures 14-inches to 17-inches diagonally and has a resolution between 1366×768 pixels to 1920×1080 pixels. The keyboard varies in size from 10-inch keyboards (such as those found on subnotebooks) to full-size keyboards such as those found on standard laptops.


1. The processor, also known as the central processing unit (CPU), acts as the brain to your laptop. It’s responsible for executing commands sent from the computer’s memory or from software running on your laptop. The speed of the processor determines how quickly your laptop responds to its commands. Processors with two cores can run two tasks at the same time, whereas processors with four cores can run up to four tasks simultaneously.


2. With each new generation, CPU manufacturers are increasing their focus on power efficiency in addition to performance and capability increases. This means that even if you have a high-end CPU, it will only use its resources when necessary to conserve battery life so it lasts longer than ever before.
