A mobile device is a general term for any type of handheld computer. These devices are designed to be extremely portable, and they can often fit in your hand. Some mobile devices—like tablets, e-readers, and smartphones—are powerful enough to do many of the same things you can do with a desktop or laptop computer.
Tablet computers
Like laptops, tablet computers are designed to be portable. However, they provide a different computing experience. The most obvious difference is that tablet computers don't have keyboards or touchpads. Instead, the entire screen is touch-sensitive, allowing you to type on a virtual keyboard and use your finger as a mouse pointer.
Tablet computers can't necessarily do everything traditional computers can do. For many people, a traditional computer like a desktop or laptop is still needed in order to use some programs. However, the convenience of a tablet computer means it may be ideal as a second computer.
E-readers
E-book readers—also called e-readers—are similar to tablet computers, except they are mainly designed for reading e-books (digital, downloadable books). Notable examples include the Amazon Kindle, Barnes & Noble Nook, and Kobo. Most e-readers use an e-ink display, which is easier to read than a traditional computer display. You can even read in bright sunlight, just like if you were reading a regular book.
Smartphones
A smartphone is a more powerful version of a traditional cell phone. In addition to the same basic features—phone calls, voicemail, text messaging—smartphones can connect to the Internet over Wi-Fi or a cellular network (which requires purchasing a monthly data plan). This means you can use a smartphone for the same things you would normally do on a computer, such as checking your email, browsing the Web, or shopping online.
Most smartphones use a touch-sensitive screen, meaning there isn't a physical keyboard on the device. Instead, you'll type on a virtual keyboard and use your fingers to interact with the display. Other standard features include a high-quality digital camera and the ability to play digital music and video files. For many people, a smartphone can actually replace electronics like an old laptop, digital music player, and digital camera in the same device.
FAQs
Can a tablet replace my laptop completely?
It depends on your needs. For browsing, email, and media, yes. However, for heavy typing, file management, or specialized software, a laptop or desktop is usually better.
Do I need internet to use a smartphone?
To use most features like email, maps, and web browsing, yes. You can connect via Wi-Fi or purchase a monthly cellular data plan from a provider.
What is the difference between an e-reader and a tablet?
E-readers have special "e-ink" screens that look like paper and are easy on the eyes, but they are mostly just for reading. Tablets have color screens and can run apps, play games, and watch videos.
Can I add a keyboard to a tablet?
Yes. Many tablets allow you to connect a physical keyboard via Bluetooth or a specialized dock, which makes typing much easier.
Do smartphones get viruses?
Yes, mobile devices can get viruses and malware, just like computers. It is important to only download apps from official stores (like the App Store or Google Play) to stay safe.
