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...

Arithmetic Logic Unit ... Early computers used a wide variety of number systems, including ones' complement, two's complement sign-magnitude format, and even true decimal systems, with various representation of the digits... Therefore, while even the simplest computer can calculate the most complicated formula, the simplest computers will usually take a long time doing that because of the several steps for calculating the formula...

Computer Multitasking ... The expression 'time sharing' was usually used to designate computers shared by interactive users at terminals, such as IBM's TSO, and VM/CMS In real-time systems, some waiting tasks are guaranteed to be given the CPU when an external event occurs... The term time-sharing is no longer commonly used, having been replaced by simply multitasking, and by the advent of personal computers and workstations rather than shared interactive systems...

Packet Switching ... Packet switching contrasts with another principal networking paradigm, circuit switching, a method which sets up a limited number of dedicated connections of constant bit rate and constant delay between nodes for exclusive use during the communication session. In case of traffic fees (as opposed to flat rate), for example in cellular communication services, circuit switching is characterized by a fee per time unit of connection time, even when no data is transferred, while packet switching is characterized by a fee per unit of information...

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...

Subnotebook ... These computers are often confused with the "ultra-mobile PC" category, which is the name of a platform of small form-factor tablet PCs...

Laptop ... As portable computers became smaller, lighter, cheaper, more powerful and as screens became larger and of better quality, laptops became very widely used for all sorts of purposes, by all sorts of people...

Motherboard ... The most popular computers such as the Apple II and IBM PC had published schematic diagrams and other documentation which permitted rapid reverse-engineering and third-party replacement motherboards... Usually intended for building new computers compatible with the exemplars, many motherboards offered additional performance or other features and were used to upgrade the manufacturer's original equipment...

Mobile Broadband ... The GSM Association of telecommunication manufacturers, mobile phone producers, integrated circuit manufacturers and notebook manufacturers have joined forces to push built-in support for mobile broadband technology on notebook computers...

CPU Design ... CPUs designed for lower performance markets might lessen the implementation burden by: Acquiring some of these items by purchasing them as intellectual property Use control logic implementation techniques (logic synthesis using CAD tools) to implement the other components - datapaths, register files, clocks Common logic styles used in CPU design include: Unstructured random logic Finite-state machines Microprogramming (common from 1965 to 1985) Programmable logic array (common in the 1980s, no longer common) Device types used to implement the logic include: Transistor-transistor logic Small Scale Integration logic chips - no longer used for CPUs Programmable Array Logic and Programmable logic devices - no longer used for CPUs Emitter-coupled logic (ECL) gate arrays - no longer common CMOS gate arrays - no longer used for CPUs CMOS ASICs - what's commonly used today, they're so common that the term ASIC is not used for CPUs Field-programmable gate ar...

Wi-Fi ... A device that can use Wi-Fi (such as a personal computer, video game console, smartphone, tablet, or digital audio player) can connect to a network resource such as the Internet via a wireless network access point. Such an access point (or hotspot) has a range of about 20 meters (65 feet) indoors and a greater range outdoors...

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...

Computer Network ... Networks may be classified according to a wide variety of characteristics such as the medium used to transport the data, communications protocol used, scale, topology, and organizational scope. Communications protocols define the rules and data formats for exchanging information in a computer network, and provide the basis for network programming...

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...

Smartbook ... A German company sold laptops under the brand Smartbook and held a trademark for the word in many countries (not including some big markets like United States, China, Japan, or India). It acted to preempt others from using the term smartbook to describe their products...

Computer Programming ... There is an ongoing debate on the extent to which the writing of programs is an art, a craft or an engineering discipline. In general, good programming is considered to be the measured application of all three, with the goal of producing an efficient and evolvable software solution (the criteria for "efficient" and "evolvable" vary considerably)...

Programmer ... Computer programmers write, test, debug, and maintain the detailed instructions, called computer programs, that computers must follow to perform their functions...

Periphere Computer-Systeme ... In addition to UNIX computers, PCS also manufactured industrial terminals. Eventually, PCS was bought out by Mannesmann-Kienzle, which in turn was bought out by Ken Olsen to become part of DEC, Digital Equipment Corporation...

High-level Programming Language ... The first high-level programming language designed for computers was Plankalkül, created by Konrad Zuse...

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...
