Drop-in Replacement
{{unreferenced, date=April 2016 Drop-in replacement is a term used in computer science and other fields. It refers to the ability to replace one hardware (or software) component with another one without any other code or configuration changes being required and resulting in no negative impacts. Usually, the replacement has some benefits including one or more of the following: * increased security * increased speed * increased feature set * increased compatibility (e.g. with other components or standards support) * increased support (e.g. the old component may no longer be supported, maintained, or manufactured) See also * Pin compatibility * Plug compatible * Clone (computing) * Backward compatibility * Kludge A kludge or kluge () is a workaround or quick-and-dirty solution that is clumsy, inelegant, inefficient, difficult to extend and hard to maintain. This term is used in diverse fields such as computer science, aerospace engineering, Internet sla ... Software architectu ...

Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ...

Computer Hardware
Computer hardware includes the physical parts of a computer, such as the computer case, case, central processing unit (CPU), Random-access memory, random access memory (RAM), Computer monitor, monitor, Computer mouse, mouse, Computer keyboard, keyboard, computer data storage, graphics card, sound card, Computer speakers, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is "Hardness, hard" or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or Instruction (computing), instruction. A combination of hardware and software forms a usable computing system, although Digital electronics, other systems exist with only hardware. Von Neumann architecture The template for all modern computers is the Von Neumann architecture, detailed in a First Draft of a Report on the EDVAC, 1945 ...

Software
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Security
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, ...

Software Feature
In software, the term feature has several definitions. The Institute of Electrical and Electronics Engineers defines the term ''feature'' in IEEE 829 as " distinguishing characteristic of a software item (e.g., performance, portability, or functionality)."IEEE Std. 829-1998 Feature-rich A piece of software is said to be "feature-rich" when it has many options and functional capabilities available to the user. Progressive disclosure is a technique applied to reduce the potential confusion caused by displaying a wealth of features at once. Sometimes if a piece of software is very feature-rich, that can be seen as a bad thing. The terms feature creep and software bloat can be used to refer to software that is overly feature-rich. See also * Feature-oriented programming * Product family engineering * Software design * Software testing * Application lifecycle management Application lifecycle management (ALM) is the product lifecycle management (governance, development, and main ...

Computer Compatibility
A family of computer models is said to be compatible if certain software that runs on one of the models can also be run on all other models of the family. The computer models may differ in performance, reliability or some other characteristic. These differences may affect the outcome of the running of the software. Software compatibility Software compatibility can refer to the compatibility that a particular software has running on a particular CPU architecture such as Intel or PowerPC. Software compatibility can also refer to ability for the software to run on a particular operating system. Very rarely is a compiled software compatible with multiple different CPU architectures. Normally, an application is compiled for different CPU architectures and operating systems to allow it to be compatible with the different system. Interpreted software, on the other hand, can normally run on many different CPU architectures and operating systems if the interpreter is available for the ...

Tech Support
Technical support (abbreviated as tech support) is a call centre type customer service provided by companies to advise and assist registered users with issues concerning their technical products. Traditionally done on the phone, technical support can now be conducted online or through chat. At present, most large and mid-size companies have outsourced their tech support operations. Many companies provide discussion boards for users of their products to interact; such forums allow companies to reduce their support costs without losing the benefit of customer feedback. Outsourcing technical support With the increasing use of technology in modern times, there is a growing requirement to provide technical support. Many organizations locate their technical support departments or call centers in countries or regions with lower costs. Dell was amongst the first companies to outsource their technical support and customer service departments to India in 2001. There has also been a grow ...

Pin Compatibility
In electronics, pin-compatible devices are electronic components, generally integrated circuits or expansion cards, sharing a common footprint and with the same functions assigned or usable on the same pins. Pin compatibility is a property desired by systems integrators as it allows a product to be updated without redesigning printed circuit boards, which can reduce costs and decrease time to market. Although devices which are pin-compatible share a common footprint, they are not necessarily electrically or thermally compatible. As a result, manufacturers often specify devices as being either ''pin-to-pin'' or ''drop-in'' compatible. Pin-compatible devices are generally produced to allow upgrading within a single product line, to allow end-of-life devices to be replaced with newer equivalents, or to compete with the equivalent products of other manufacturers. Pin-to-pin compatibility ''Pin-to-pin compatible'' devices share an assignment of functions to pins, but may have di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plug Compatible
Plug compatible refers to " hardware that is designed to perform exactly like another vendor's product." The term PCM was originally applied to manufacturers who made replacements for IBM peripherals. Later this term was used to refer to IBM-compatible computers. PCM and peripherals Before the rise of the PCM peripheral industry, computing systems were either configured with peripherals designed and built by the CPU vendor, or designed to use vendor-selected rebadged devices. The first example of plug compatible IBM subsystems were tape drives and controls offered by Telex beginning 1965. Memorex in 1968 was first to enter the IBM plug-compatible disk followed shortly thereafter by a number of suppliers such as CDC, Itel, and Storage Technology Corporation. This was boosted by the world's largest user of computing equipment in both directions. Ultimately plug-compatible products were offered for most peripherals and system main memory.

Clone (computing)
In computing, a clone is hardware or software that is designed to function in exactly the same way as another system. A specific subset of clones are remakes (or remades), which are revivals of old, obsolete, or discontinued products. Motivation Clones and remakes are created for some reasons, including competition, standardization, availability across platforms, and even as homage. Compatibility with the original system is usually the explicit purpose of cloning hardware or low-level software such as operating systems (e.g. AROS and MorphOS are intended to be compatible with AmigaOS). Application software is cloned by providing the same functionality. Commercially-motivated clones are made often during a competitor product's initial successful commercial run, intentionally competing with the original and trying to participate in their success. Hardware Hardware clones When IBM announced the IBM PC in 1981, other companies such as Compaq decided to offer clones of the PC ...

Backward Compatibility
Backward compatibility (sometimes known as backwards compatibility) is a property of an operating system, product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system, especially in telecommunications and computing. Modifying a system in a way that does not allow backward compatibility is sometimes called " breaking" backward compatibility. A complementary concept is forward compatibility. A design that is forward-compatible usually has a roadmap for compatibility with future standards and products. A related term from programming jargon is hysterical reasons or hysterical raisins (near-homophones for "historical reasons"), as the purpose of some software features may be solely to support older hardware or software versions. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM radio in stereo. FM radio was initially mono, with only one audio channel represented ...

Kludge
A kludge or kluge () is a workaround or quick-and-dirty solution that is clumsy, inelegant, inefficient, difficult to extend and hard to maintain. This term is used in diverse fields such as computer science, aerospace engineering, Internet slang, evolutionary neuroscience, and government. It is similar in meaning to the naval term ''jury rig''. Etymology The word has alternate spellings (''Wikt:kludge, kludge'' and ''Wikt:kluge, kluge''), pronunciations ( and , rhyming with ''judge'' and ''stooge'', respectively), and several proposed etymologies. Jackson W. Granholm The ''Oxford English Dictionary'' (2nd ed., 1989), cites Jackson W. Granholm's 1962 "How to Design a Kludge" article in the American computer magazine ''Datamation''. kludge Also kluge. [J. W.
