Laptop Computer

A laptop is basically a portable computer. It has no base unit and has no need for external components (as it has an inbuilt mouse pad, keyboard, monitor and sometimes an inbuilt camera), it is just one item. Although, as with the desktop computer, other external components can be added via wireless, USB, Bluetooth or PS2 connectors.

Tablet Computer

A tablet is another version of a portable desktop computer. The tablet is typically touchscreen, meaning that it is intractable by touch. As it is typically touchscreen, no external components are needed and there is only an inbuilt intractable monitor with few buttons for various commands. Tablets have been around for some time but have only recently been reintroduced.

Smartphones

A smartphones is another version of a portable computer. Smartphones are a fairly recent invention in the scale of things. Although phones have been round for some time, they used to be able to only be able to send texts and phone people and maybe play the occasional game. Nowadays, they can virtually do anything a computer can do including still being able to text and phone!

There are many types of games consoles (GameCube, DS, PS, PSP Xbox, Wii, etc.) so it cannot be defined with one style. Some game consoles can have external components but typically no conventional external components are used (mouse, keyboard etc.)
