A laptop is a computer that is intended to run anywhere as it is portable. Laptops have integrated screens and keyboards and run on batteries. Heavy use to some hardware such as GPU, DVD drives can quickly drain the batteries. Laptops have a touchpad, pointing stick, trackball, or other pointing device. Nowadays, we can add external devices like mouse, keyboard etc.
Notebooks are stripped-down laptops. They are thin and have relatively small screens and are ultra-light. They rarely have CD-ROM or DVD and also have very limited graphics capabilities. As notebooks doesn’t have external media (DVD, etc), they typically have integrated network connection hardware so one can load software on to them. Network hardware can be used to access the internet.
Netbooks are even more stripped down than notebooks. They typically have less powerful processors and are primarily used for networked applications as web browsers, where most of the processing happens on a remote server.
A tablet is similar to laptop that uses touch screen or stylus as its primary input device. Tablets may display virtual keyboards on their screens and may use handwriting recognition for text input.Lap
