SoulPad is a mobile computing project developed by IBM that enables users to transfer their operating system between computers using a USB flash drive, to offer a portable, mobile operating system.
The SoulPad project was introduced in a 2004 research paper, titled: "Reincarnating PCs with Portable SoulPads". [1] Researchers suggested that SoulPad could allow users to boot their personal operating environments from USB-compatible storage devices, such as cell phones or iPods. The project aimed to separate the user's operating environment (the "soul") from the physical hardware (the "body").
SoulPad allows users to carry their operating system on a USB storage device. The operating system can be copied onto the device, then connected onto another computer and booted from the USB. This restores the operating system to the state of its last saved backup, enabling the user to resume work as if the environment had not been interrupted. [2]
SoulPad utilizes a layered software stack to implement its functionality. It uses the Live Linux distribution Knoppix as a host operating system. When the computer is powered on, Knoppix recognizes any attached devices and launches a virtual machine using VMware, which resumes the user's last session in their operating system. This process enables the system to restore the user's workspace on different hardware while maintaining functionality.
Several challenges were identified during the development of SoulPad. One of the primary issues is the time required to resume the system from a saved state, which can take up to three minutes. This delay is attributed to Knoppix's need to recognize all connected devices. Security concerns have also been raised regarding access to the local disks of the temporary host computer. To address these issues, the researchers proposed creating system profiles to improve performance and mitigate security risks. [3]
A personal digital assistant (PDA) is a multi-purpose mobile device which functions as a personal information manager. Following a boom in the 1990s and 2000s, PDA's were mostly displaced by the widespread adoption of more highly capable smartphones, in particular those based on iOS and Android in the late 2000's, and thus saw a rapid decline.
In computing, firmware is software that provides low-level control of computing device hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality. For a more complex device, firmware may provide relatively low-level control as well as hardware abstraction services to higher-level software such as an operating system.
Knoppix, stylized KNOPPIX, is an operating system based on Debian designed to be run directly from a CD / DVD or a USB flash drive. It was first released in 2000 by German Linux consultant Klaus Knopper, and was one of the first popular live distributions. Knoppix is loaded from the removable medium and decompressed into a RAM drive. The decompression is transparent and on-the-fly.
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is fitted inside the lower lid enclosure under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers.
ThinkPad is a line of business-oriented laptop computers and tablets, the early models of which were designed, developed and marketed by International Business Machines (IBM) starting in 1992. IBM sold its PC business, including laptops to Lenovo in 2005, and since 2007, all new ThinkPad models have been branded Lenovo instead. The Chinese manufacturer further developed the line, and is still selling new models in 2024.
Mobile computing is human–computer interaction in which a computer is expected to be transported during normal usage and allow for transmission of data, which can include voice and video transmissions. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc networks and infrastructure networks as well as communication properties, protocols, data formats, and concrete technologies. Hardware includes mobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications.
A handheld personal computer (PC), typically built around either a clamshell form factor or a gaming form factor with a gamepad integrated for video games, is a mobile device that is significantly smaller than any standard personal computer (PC), but based on the same principles as PCs. The clamshell form factor is sometimes referred to as a palmtop computer, not to be confused with Palmtop PC which was a name used mainly by Hewlett-Packard.
ShapeWriter was a keyboard text input method for tablet, handheld PCs, and mobile phones invented by Shumin Zhai and Per Ola Kristensson at IBM Almaden Research Center and the Department of Computer and Information Science at Linköping University.
The PS/2 port is a 6-pin mini-DIN connector used for connecting keyboards and mice to a PC compatible computer system. Its name comes from the IBM Personal System/2 series of personal computers, with which it was introduced in 1987. The PS/2 mouse connector generally replaced the older DE-9 RS-232 "serial mouse" connector, while the PS/2 keyboard connector replaced the larger 5-pin/180° DIN connector used in the IBM PC/AT design. The PS/2 keyboard port is electrically and logically identical to the IBM AT keyboard port, differing only in the type of electrical connector used. The PS/2 platform introduced a second port with the same design as the keyboard port for use to connect a mouse; thus the PS/2-style keyboard and mouse interfaces are electrically similar and employ the same communication protocol. However, unlike the otherwise similar Apple Desktop Bus connector used by Apple, a given system's keyboard and mouse port may not be interchangeable since the two devices use different sets of commands and the device drivers generally are hard-coded to communicate with each device at the address of the port that is conventionally assigned to that device.
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen 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 laptops, tablets usually run mobile operating systems, alongside smartphones.
A live USB is a portable USB-attached external data storage device containing a full operating system that can be booted from. The term is reminiscent of USB flash drives but may encompass an external hard disk drive or solid-state drive, though they may be referred to as "live HDD" and "live SSD" respectively. They are the evolutionary next step after live CDs, but with the added benefit of writable storage, allowing customizations to the booted operating system. Live USBs can be used in embedded systems for system administration, data recovery, or test driving, and can persistently save settings and install software packages on the USB device.
The PC System Design Guide is a series of hardware design requirements and recommendations for IBM PC compatible personal computers, compiled by Microsoft and Intel Corporation during 1997–2001. They were aimed at helping manufacturers provide hardware that made the best use of the capabilities of the Microsoft Windows operating system, and to simplify setup and use of such computers.
A personal computer, often referred to as a PC, is a computer designed for individual use. It is typically used for tasks such as word processing, internet browsing, email, multimedia playback, and gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people.
DOS is a family of disk-based operating systems for IBM PC compatible computers. The DOS family primarily consists of IBM PC DOS and a rebranded version, Microsoft's MS-DOS, both of which were introduced in 1981. Later compatible systems from other manufacturers include DR-DOS (1988), ROM-DOS (1989), PTS-DOS (1993), and FreeDOS (1998). MS-DOS dominated the IBM PC compatible market between 1981 and 1995.
A legacy-free PC is a type of personal computer that lacks a floppy or optical disc drive, legacy ports, and an Industry Standard Architecture (ISA) bus. According to Microsoft, "The basic goal for these requirements is that the operating system, devices, and end users cannot detect the presence of the following: ISA slots or devices; legacy floppy disk controller (FDC); and PS/2, serial, parallel, and game ports." The legacy ports are usually replaced with Universal Serial Bus (USB) ports. A USB adapter may be used if an older device must be connected to a PC lacking these ports. According to the 2001 edition of Microsoft's PC System Design Guide, a legacy-free PC must be able to boot from a USB device.
The history of tablet computers and the associated special operating software is an example of pen computing technology, and thus the development of tablets has deep historical roots. The first patent for a system that recognized handwritten characters by analyzing the handwriting motion was granted in 1914. The first publicly demonstrated system using a tablet and handwriting recognition instead of a keyboard for working with a modern digital computer dates to 1956.
A 2-in-1 laptop, also known as 2-in-1 PC, 2-in-1 tablet, laplet, tabtop, laptop tablet, or simply 2-in-1, is a portable computer that has features of both tablets and laptops.
The post-PC era was a market trend observed during the late 2000s and early 2010s involving a decline in the sales of personal computers (PCs) in favor of post-PC devices; which include mobile devices such as smartphones and tablet computers as well as other mobile computers such as wearable and ubiquitous ones. These devices emphasize portability and connectivity, including the use of cloud-based services, more focused "apps" to perform tasks, and the ability to synchronize information between multiple devices seamlessly.
In computing, a hardware code page (HWCP) refers to a code page supported natively by a hardware device such as a display adapter or printer. The glyphs to present the characters are stored in the alphanumeric character generator's resident read-only memory and are thus not user-changeable. They are available for use by the system without having to load any font definitions into the device first. Startup messages issued by a PC's System BIOS or displayed by an operating system before initializing its own code page switching logic and font management and before switching to graphics mode are displayed in a computer's default hardware code page.
Pocket PC 2000 was the first member of the Windows Mobile family of mobile operating systems that was released on April 19, 2000, and was based on Windows CE 3.0. It is the successor to the operating system aboard Palm-size PCs. Backwards compatibility was retained with such Palm-size PC applications.
