Tablets are single-panel touchscreen computers that are smaller than laptops. They have apps and web browsers. Early tablets date back to 1979 but modern tablets grew popular around 2010. Tablet use in businesses is also increasing, with over 900 million projected to be in use by 2016. Businesses commonly use tablets for file sharing, collaboration, and communication via apps, document sharing, meetings, and social media. However, some disadvantages are that not all prefer tablets over PCs and security could be an issue.
