A tablet is a portable computer with a touchscreen and no keyboard attached
A tablet is a flat, handheld device that runs on a rechargeable battery and lets you interact with it by touching the screen directly with your fingers. Unlike a laptop, it has no physical keyboard or trackpad built in—you type on a virtual keyboard that appears on the screen when you need it. The most common tablets are Apple iPads, Samsung Galaxy Tabs, and Amazon Fire tablets, though many other manufacturers make them too.
The screen is the main way you control everything. You tap icons to open apps, swipe to move between pages, pinch to zoom in and out, and drag items around. Because there's no keyboard taking up space, tablets are lighter and thinner than laptops, which makes them easier to hold in one hand or carry in a bag.
Key Takeaways
- A tablet is a touchscreen computer without a built-in keyboard that you control by tapping and swiping with your fingers.
- Tablets run operating systems like iPadOS, Android, or Windows, which determine what apps you can use and how the device works.
- You can add an external keyboard and stylus to a tablet if you want to type more or draw, but these are optional extras.
- Tablets are smaller and lighter than laptops but larger than phones, making them good for reading, watching video, and light work.
- Most tablets connect to the internet through Wi-Fi, and some models also have cellular data so you can use them anywhere.
The main parts of a tablet and what they do
The screen is a touchscreen, meaning it responds when you touch it with your finger or a stylus. It displays everything—apps, websites, photos, text. The size varies: most tablets have screens between 7 and 13 inches diagonally, measured corner to corner.
The processor is the chip inside that does the thinking. It's similar to the brain of a computer. A faster processor means apps open quicker and video plays more smoothly. Different tablets have different processors—Apple uses its own chips (like the A14 or M1), while Android tablets often use Snapdragon or MediaTek chips.
The battery is rechargeable and usually lasts 8 to 12 hours of regular use before you need to plug it in. You charge it with a cable, just like a phone. The storage is where everything lives—your apps, photos, documents, and videos. Tablets come with different amounts: 32GB, 64GB, 128GB, or more. The more storage you have, the more you can keep on the device.
Most tablets have a camera on the back and front. The back camera is usually better quality for taking photos and video. The front camera is smaller and used mainly for video calls. Tablets also have speakers built in, usually on the sides or bottom, so you can listen to music, watch videos, or take calls without headphones.
Operating systems: the software that runs your tablet
Every tablet runs an operating system—the core software that makes it work. The operating system controls how the device behaves, what apps you can install, and how everything looks on screen. The three main operating systems are iPadOS (on Apple iPads), Android (on most other tablets), and Windows (on Microsoft Surface tablets).
iPadOS is made by Apple and only runs on iPads. It's known for being smooth and straightforward, with a clean design. Apps for iPads are sold through the Apple App Store. Android is made by Google and runs on tablets from Samsung, Amazon, Lenovo, and many others. Android offers more variety in device styles and prices. Apps come from the Google Play Store or other sources. Windows is the same system that runs on desktop and laptop computers, so if you're used to a Windows PC, a Surface tablet will feel familiar.
The operating system you choose matters because it determines which apps you can use. Some apps exist only on iPad, some only on Android, and some on both. Before you buy a tablet, think about which apps matter to you and check whether they're available on that system.
How tablets are different from phones and laptops
A tablet sits between a phone and a laptop in size and power. A phone fits in your pocket and is always with you, but the screen is small—usually 5 to 7 inches. A laptop has a keyboard and trackpad, weighs more, and is better for serious work like writing or spreadsheets. A tablet is bigger than a phone so reading and watching video are more comfortable, but smaller and lighter than a laptop so it's easier to hold and carry.
Tablets are better than phones for reading books, browsing the web, watching shows, and drawing or taking notes. They're worse than laptops for typing long documents or doing work that needs a keyboard and mouse. Many people use a tablet for leisure and a laptop for work, though you can add a keyboard to a tablet if you want to do more typing.
Connecting to the internet on a tablet
Most tablets connect to the internet through Wi-Fi, the same wireless network your home computer uses. You need a Wi-Fi router and a password to connect. Once you're on Wi-Fi, you can browse the web, stream video, read apps, and send email.
Some tablets also have cellular data, which means they can connect to the internet through a phone network (like 4G or 5G) even when Wi-Fi isn't available. This is useful if you travel or want to use your tablet anywhere. Cellular tablets cost more upfront and require a monthly data plan from a phone company, similar to what you'd pay for a phone.
A few tablets have Bluetooth, which lets you connect wireless headphones, speakers, keyboards, or a mouse without a cable. This is handy if you want to type more comfortably or listen to audio without wires.
Optional accessories that extend what a tablet can do
You don't need any extras to use a tablet—the touchscreen is enough. But several accessories can make a tablet more useful for specific tasks. A keyboard case or external keyboard lets you type faster and more comfortably, turning your tablet into something closer to a laptop. Some keyboard cases also prop the tablet up at an angle so you can see the screen better.
A stylus (also called a pen) lets you write and draw on the screen with precision. If you like to take handwritten notes or do digital art, a stylus makes that much easier than using your finger. Apple Pencil is the stylus for iPads; Android tablets use different styluses depending on the brand.
A screen protector is a thin sheet of glass or plastic you stick to the screen to protect it from scratches and cracks. A case protects the whole device if you drop it. A stand props your tablet up so you can watch video hands-free. None of these are necessary, but they can make your tablet more comfortable to use for specific things.
Frequently Asked Questions
Can I use a tablet to replace my laptop?
It depends on what you do. If you mainly read, watch video, and browse the web, a tablet works fine. If you need to type a lot, use specialized software, or do detailed work, a laptop is usually better. Many people use both—a tablet for casual use and a laptop for serious work.
Do I need to buy apps, or are they free?
Most apps are free, but some cost money—usually between $1 and $15. You buy them once through the app store on your tablet and they're yours to keep. Some apps are free but show ads, or free with optional paid features inside the app.
How long does a tablet battery last?
Most tablets last 8 to 12 hours of regular use on a full charge. If you're just reading or browsing, it might last longer. If you're streaming video or playing games, it might last less. The battery gets weaker over time—after a few years, you might notice it doesn't last as long as it did when new.
Can I connect a mouse to a tablet?
Yes, if your tablet has Bluetooth. You can pair a wireless mouse and use it instead of touching the screen. This is helpful if you're doing detailed work or prefer a mouse to your finger, though most tablets are designed to work best with touch.
What's the difference between Wi-Fi and cellular tablets?
Wi-Fi tablets only connect to the internet when you're near a Wi-Fi network. Cellular tablets can also connect through a phone network anywhere you have signal, but they cost more and need a monthly data plan. Choose Wi-Fi if you mostly use your tablet at home or in places with Wi-Fi; choose cellular if you travel often and want internet everywhere.
