Desktop

A desktop computer is a personal computer in a form intended for regular use at a single location desk/table due to its size and power requirements. The most common configuration is a computer monitor, keyboard and mouse, and a case that houses the main components of the PC, namely the power supply, motherboard, hard drive, optical drive, and previously the floppy drive.

                                     

All in One

An all-in-one desktop computer integrates the system's internal components into the same case as the display, eliminating some connecting cables and allowing for a smaller footprint, sometimes giving a degree of portability, compared to the standard desktop configuration of the separate display monitor and computer system case.

LAPTOP

A laptop is a personal computer that can be easily carried and used in a variety of locations. Many laptops are designed to have all of the functionality of a desktop computer, which means they can generally run the same software and open the same types of files.

A laptop has an all-in-one design, with a built-in monitor, keyboard, touchpad (which replaces the mouse), and speakers. This means it is fully functional, even when there are no peripherals attached to it. A laptop is quicker to set up, and there are fewer cables to get in the way.

NETBOOK

A small portable computing device, similar to a notebook. However, it has a smaller form factor and comes with more limited features. What differentiates a netbook from a notebook is its physical size and computing power.

A netbook typically has a small display, ranging from 7 to 10 inches. It weighs under 3 pounds, and support a keyboard that is reduced in size from 75 to 80 percent when compared to a standard keyboard.

TABLET PC

A tablet computer, or simply tablet, is a mobile computer with display, circuitry and battery in a single unit. Tablets are equipped with sensors, including cameras, microphone, accelerometer and touchscreen, with finger or stylus gestures replacing computer mouse and keyboard. 

Tablets may include physical buttons, e.g., to control basic features such as speaker volume and power and ports for network communications and to charge the battery.

A tablet is a wireless, portable personal computer with a touchscreen interface. The tablet form factor is typically smaller than a notebook computer but larger than a smartphone.
