A tablet computador[2], often just called a tablet, is a wireless, portable personal computer with a touchscreen interface. The concept of a tablet was first introduced in the 20th century with pen computing, and actual products came to market in the 1980s from companies like GRiD Systems and Apple. Since then, the tecnologia[1] has evolved significantly, experimenting with various input/output types and paving the way for modern tablets. As of 2021, there are approximately 1.28 billion tablet users worldwide, with Apple, Samsung[3], and Lenovo leading in the manufacturer market share. Tablets come in various forms and sizes, catering to different user needs and preferences. They are known for their touchscreens, mobile operating systems, Wi-Fi and Bluetooth connectivity, and often, the ability to recognize handwriting with stylus input. The future of tablet technology is expected to see advancements in hardware, software, and form factors.
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a sistema operativo móvel e ecrã tátil display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens 7 inches (18 cm) or larger, measured diagonally, and may not support access to a cellular network. Unlike computadores portáteis (which have traditionally run off operating systems usually designed for desktops), tablets usually run mobile operating systems, alongside smartphones.
The touchscreen display is operated by gestures executed by finger or digital pen (stylus), instead of the mouse, touchpade teclado of larger computers. Portable computers can be classified according to the presence and appearance of physical keyboards. Two species of tablet, the slate e booklet, do not have physical keyboards and usually accept text and other input by use of a virtual keyboard shown on their touchscreen displays. To compensate for their lack of a physical keyboard, most tablets can connect to independent physical keyboards by Bluetooth ou USB; 2-in-1 PCs have keyboards, distinct from tablets.
The form of the tablet was conceptualized in the middle of the 20th century (Stanley Kubrick depicted fictional tablets in the 1968 science fiction film 2001: A Space Odyssey) and prototyped and developed in the last two decades of that century. In 2010, Apple released the iPad, the first mass-market tablet to achieve widespread popularity. Thereafter, tablets rapidly rose in ubiquity and soon became a large product category used for personal, educational and workplace applications. Popular uses for a tablet PC include viewing presentations, video-conferencing, reading e-books, watching movies, sharing photos and more. As of 2021 there are 1.28 billion tablet users worldwide according to data provided by Statista, while Apple holds the largest manufacturer market share followed by Samsung e Lenovo.
