Simputer
The Simputer was a self-contained, open hardware Linux-based handheld computer, first released in 2002. Developed in, and primarily distributed within India, the product was envisioned as a low-cost alternative to personal computers. With initial goals of selling 50,000 simputers, the project had sold only about 4,000 units by 2005, and has been called a failure by news sources. Design and Hardware The device was designed by the Simputer Trust, a non-profit organization formed in November 1999 by seven Indian scientists and engineers led by Dr. Swami Manohar. The word "Simputer" is an acronym for "simple, inexpensive and multilingual people's computer", and is a trademark of the Simputer Trust. The device includes text-to-speech software and runs the Linux operating system. Similar in appearance to the PalmPilot class of handheld computers, the touch sensitive screen is operated on with a stylus; simple handwriting recognition software is provided by the program Tapa ...

Swami Manohar
Swami Manohar, otherwise known as Manohar Swaminathan, is a co-founder and the CEO of PicoPeta Simputers Pvt. Ltd. He completed his undergraduate program in Electronics and Communication Engineering in Government College of Technology, Coimbatore during which he was a part of a campus team that designed an Electronic Voting machine in the year 1981, which was actually the first designed in India. After obtaining his PhD in Computer Science from Brown University he was a faculty at the University of North Carolina for two years and then was at the Indian Institute of Science ( IISc), Bangalore, between 1990 and 2005. He was on the faculty of the department of Computer Science and Automation (CSA) and the Supercomputer Education and Research Center (SERC) at the Institute. He has been a visiting faculty at Columbia University, University of Missouri and the University of Texas. While at IISc, he co-invented the Simputer, was awarded the Dewang Mehta Award for Innovation in IT, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-source Hardware
Open-source hardware (OSH) consists of physical artifacts of technology designed and offered by the open-design movement. Both free and open-source software (FOSS) and open-source hardware are created by this open-source culture movement and apply a like concept to a variety of components. It is sometimes, thus, referred to as FOSH (free and open-source hardware). The term usually means that information about the hardware is easily discerned so that others can make it – coupling it closely to the maker movement. Hardware design (i.e. mechanical drawings, schematics, bills of material, PCB layout data, HDL source code and integrated circuit layout data), in addition to the software that drives the hardware, are all released under free/ libre terms. The original sharer gains feedback and potentially improvements on the design from the FOSH community. There is now significant evidence that such sharing can drive a high return on investment for the scientific community. It i ...

StrongARM
The StrongARM is a family of computer microprocessors developed by Digital Equipment Corporation and manufactured in the late 1990s which implemented the ARM v4 instruction set architecture. It was later acquired by Intel in 1997 from DEC's own Digital Semiconductor division as part of a settlement of a lawsuit between the two companies over plagiarism. Intel then continued to manufacture it before replacing it with the StrongARM-derived ARM-based follow-up architecture called XScale in the early 2000s. History According to Allen Baum, the StrongARM traces its history to attempts to make a low-power version of the DEC Alpha, which DEC's engineers quickly concluded was not possible. They then became interested in designs dedicated to low-power applications which led them to the ARM family. One of the only major users of the ARM for performance-related products at that time was Apple, whose Newton device was based on the ARM platform. DEC approached Apple wondering if they mig ...

Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a ''internetworking, network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and Web application, applications of the World Wide Web (WWW), email, electronic mail, internet telephony, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and mi ...

Spreadsheet
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term ''spreadsheet'' may also refer to one such electronic document. Spreadsheet users can adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets and can display data either as text and numerals or in graphical form. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financia ...
