A Handheld device (also known as handheld computer or simply handheld) is a pocket-sized computing device, typically utilising a small visual display screen for user output and a miniaturised keyboard for user input. In the case of the Personal digital assistant the input and output are combined into a touch-screen interface. Along with mobile computing devices such as laptops and smartphones, personal digital assistants (PDAs) are becoming increasingly popular amongst those who require the assistance and convenience of a conventional computer, in environments where carrying one would not be practicable.

Categories of mobile devices
Due to the varying levels of functionality associated with mobile devices, in 2005 T38 and the DuPont Global Mobility Innovation Team proposed the following standardized definition of mobile devices:
Limited Data Mobile Device: devices that have a small, primarily text-based screen, with data services usually limited to SMS (Short Message Service) and WAP access. Typical examples of these devices are cellular phones.
Basic Data Mobile Device: devices that have a medium-size screen (typically between 120 x 120 and 240 x 240 pixels), menu or icon-based navigation via a thumb-wheel or cursor, and which offer access to e-mail, address book, SMS, and a basic web browser. Typical examples of these devices are BlackBerry and Smartphone.
Enhanced Data Mobile Device: devices that have medium to large screens (typically above 240 x 120 pixels), stylus-based navigation, and which offer the same features as the "Basic Data Mobile Devices" plus native applications such as Microsoft Office applications (Word, Excel, PowerPoint) and custom corporate applications such as mobilized versions of SAP, intranet portals, etc. Typical devices include those running Windows Mobile 2003 or version 5, such as Pocket PCs.
