Handheld Computers Guide What To Know When Purchasing Your New PDA

Software Industry ... The software industry expanded in the early 1960s, almost immediately after computers were first sold in mass-produced quantities...

Internet Privacy ... Internet privacy forms a subset of computer privacy. A number of experts within the field of Internet security and privacy believe that privacy doesn't exist; "Privacy is dead – get over it" according to Steve Rambam, private investigator specializing in Internet privacy cases...

Computer Program ... Computer source code is often written by computer programmers. Source code is written in a programming language that usually follows one of two main paradigms: imperative or declarative programming...

Central Processing Unit ... On personal computers and small workstations, the CPU is housed in a single silicon chip called a microprocessor...

Software Bug ... Bugs trigger errors that can in turn have a wide variety of ripple effects, with varying levels of inconvenience to the user of the program. Some bugs have only a subtle effect on the program's functionality, and may thus lie undetected for a long time...

TOP500 ... The TOP500 list is compiled by Hans Meuer of the University of Mannheim, Germany, Jack Dongarra of the University of Tennessee, Knoxville, and Erich Strohmaier and Horst Simon of NERSC/Lawrence Berkeley National Laboratory. Project history In the early 1990s, a new definition of supercomputer was needed to produce meaningful statistics...

Desktop Replacement Computer ... Desktop replacement computers are also often used with a port replicator, to fully enjoy the desktop comfort... Design features Modern desktop replacements generally perform better than traditional laptop-style computers as their size allows the inclusion of more powerful components... However, these advantages generally come at a price premium, with many computers in this class costing as much as two desktop computers with similar specifications...

Personal Digital Assistant ... The first PDA was released in 1986 by Psion, the Organizer II. Followed by Psion's Series 3, in 1991, which began to resemble the more familiar PDA style...

Computer Data Storage ... In contemporary usage, 'memory' usually refers to semiconductor storage read-write random-access memory, typically DRAM (Dynamic-RAM). Memory can refer to other forms of fast but temporary storage...

Supercomputer ... in grid computing the processing power of a large number of computers in distributed, diverse administrative domains, is opportunistically used whenever a computer is available... History The history of supercomputing goes back to the 1960s when a series of computers at Control Data Corporation (CDC) were designed by Seymour Cray to use innovative designs and parallelism to achieve superior computational peak performance...

History Of Computing Hardware ... Computing hardware evolved from machines that needed separate manual action to perform each arithmetic operation, to punched card machines, and then to stored-program computers... The history of stored-program computers relates first to computer architecture, that is, the organization of the units to perform input and output, to store data and to operate as an integrated mechanism (see block diagram to the right)... As all computers rely on digital storage, and tend to be limited by the size and speed of memory, the history of computer data storage is tied to the development of computers...

Computer ... Conventionally a computer consists of some form of memory, at least one element that carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from an external source, and allow the results of operations to be sent out...

Multiprocessing ... Multiprocessing sometimes refers to the execution of multiple concurrent software processes in a system as opposed to a single process at any one instant. However, the terms multitasking or multiprogramming are more appropriate to describe this concept, which is implemented mostly in software, whereas multiprocessing is more appropriate to describe the use of multiple hardware CPUs...

Internet Protocol Suite ... The Internet protocol suite has four abstraction layers, each with its own protocols. From lowest to highest, the layers are: The link layer contains communication technologies for a local network...

History Of Laptops ... Compaq SLT/286 By the end of the 1980s, laptop computers were becoming popular among business people...

Rugged Computer ... Construction Virtually all rugged computers share an underlying design philosophy of providing a controlled environment for the installed electronics...

Programming Language ... The earliest programming languages predate the invention of the computer, and were used to direct the behavior of machines such as Jacquard looms and player pianos. Thousands of different programming languages have been created, mainly in the computer field, with many more being created every year...
