Explanation:
Tablets are more portable than any computer or laptop. They are very lightweight and can fit in a purse or small bag with relative ease. They are designed to be taken everywhere with you, thus the very definition of portable.
Storage Computer hard drives can be over one TB (terabyte). Even the most basic computer comes with a 250 GB (gigabyte) hard drive, which for many is more than enough storage for most users. Tablets come with built-in storage ranging from 8 GB to 128 GB. In some cases, an expansion slot may be available for adding additional storage.

Tablets use an on-screen keyboard that is smaller than a standard computer keyboard, takes time to learn, and users with bigger fingers may have a hard time typing. Some tablets allow for an external keyboard, providing a more comfortable and familiar medium for typing.
Touch screen Although some laptops and desktops now support touch, most still have no touch screen support. All tablets support a touch screen, that's easier for new computer.
