Whats the difference between computers and tablets
inysia [295]

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.

Battery life The battery life even for the most efficient laptop is still not close to the battery life of a tablet. A tablet has a much smaller screen and has fewer components than a laptop computer, which makes for a longer battery life.

Operating System Desktop and laptop computers come with more fully featured operating system due to having the computing power and memory requirements. These operating systems support more than any tablet operating system. Tablets come with a more slimmed down operating system because of the limited computing power and memory. The Android OS and Apple iOS are adequate operating systems for tablet users, but not as complete as computer operating systems.

Boot time The latest computers running the latest operating systems have improved a lot on their boot time. However, are still slower than a tablet. Generally speaking, most tablets are much faster at booting than most computers.

Data entry and user input A computer uses a keyboard for data entry that most users are familiar with and comfortable using. The mouse is also available for easy scrolling and right-clicking. 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.
