Handheld PCs, commonly known as palmtop computers, are portable computing devices akin to Personal Digital Assistants (PDAs). Unlike PDAs, Handheld PCs often run full versions of operating systems, such as Windows CE, providing a broader range of functionalities akin to desktop and laptop computers but in a compact form factor.
Definition of Handheld PCs
Handheld PCs are small, portable computing devices designed for mobile use. They integrate the functionalities of traditional computers with the portability of handheld devices. Typically, these devices feature a built-in keyboard, touch screen, and run full operating systems like Windows CE. They are often used in fieldwork, remote data entry, and as portable solutions for professionals who require computing power on the go.
Characteristics of Handheld PCs
Operating Systems
Handheld PCs usually run specialized versions of desktop operating systems designed for mobile hardware. Notable examples include:
- Windows CE: A compact operating system by Microsoft designed specifically for embedded systems.
- Linux-based OS: Some handheld PCs run customized Linux distributions optimized for mobile use.
Hardware Components
- Processors: Typically use low-power processors such as ARM or Intel Atom.
- Memory: Generally have limited RAM and storage compared to desktop PCs.
- Input Methods: Integrated keyboards, touchscreens, and sometimes stylus support.
Connectivity
- Wireless Communication: Wi-Fi, Bluetooth, and sometimes cellular connectivity.
- Ports: USB, SD card slots, and occasionally HDMI outputs.
Historical Context of Handheld PCs
The concept of portable computing dates back to the 1980s, but it was the 1990s that saw the rise of Handheld PCs, largely driven by advancements in miniature hardware and the need for mobile computing solutions. Products like the HP Jornada and Compaq’s iPAQ were among the first to bring Windows CE to portable devices, catering to both consumer and professional markets.
Examples of Handheld PCs
- HP Jornada Series: Featured full QWERTY keyboards and ran Windows CE.
- Compaq iPAQ: Known for its versatility and expandability with add-on sleeves.
- Psion Series 5: A popular choice running the EPOC operating system.
Applications and Use Cases
Handheld PCs are utilized in various fields, including:
- Field Research: For data collection and analysis in remote locations.
- Healthcare: Providing portable access to patient records and medical databases.
- Logistics: Inventory management and real-time tracking in warehouses.
Comparisons to PDAs and Modern Devices
PDAs vs Handheld PCs
- PDAs: Primarily used for personal information management (PIM), often with simpler OS like Palm OS or Microsoft Pocket PC.
- Handheld PCs: Offer more comprehensive computing capabilities with full operating systems.
Modern Replacements
With the advent of powerful smartphones and tablets, the demand for traditional Handheld PCs has significantly declined. Modern devices such as Apple’s iPhone and iPad, along with Android smartphones and tablets, now provide similar functionalities with advanced features and app ecosystems.
Related Terms
