A technical trainer is an educator or teacher who trains or coaches others in some field of technology. The task requires a certain set of competencies, but many technical trainers do not hold specific technical-training qualifications. Although there are professional organizations and publications of relevance to technical trainers, few of these are specifically focused on that profession.Types of technical trainers[edit]Although a generic professional description can be applied to all technical trainers, as is true of any profession, many specializations exist. These include information technology topics such as Computer applications and Computer Architecture and Design; biomedical technology; educational technology; and topics in the field of engineering.History[edit]The need for technical training existed before computers or even electronics, but the term "technical trainer" has only been in the common lexicon since the mid-20th century.[1] For example, RAF Technical Training Command was a distinct unit between 1940 and 1968, providing training in aircraft maintenance and other non-flying activities to British forces.[2]Competencies[edit]It is often pointed out that effective technical trainers need qualities over and above technical mastery. They need to have skills in working with people, and knowledge of a range of training techniques.[3] The former National Skill Standards Board in the United States developed a set of skill standards for technical trainers.[4]Certification[edit]Currently, competence frameworks for technical trainers are not well developed.[5] Among those technical trainers who have university degrees, the most frequent degree is in education; but many technical trainers are not formally qualified in the field.[6]Several organizations do provide certification for teachers and other educators in technology. For example, the American trade association CompTIA provides the CTT+ (Certified Technical Trainer) qualification, which is internationally recognized for trainers in the information technology field.[7]Professional organizations[edit]The Association for Talent Development, formerly American Society for Training and Development, is a non-profit association for workplace learning and performance professionals. It organizes two regular international conferences relevant to technical trainers: its national convention, and the Techknowledge Conference on e-learning. Up to the mid-1990s it published a magazine and hosted a conference specifically for technical trainers.[8]The International Society for Performance Improvement (ISPI) organizes an annual conference and other educational events, publishes books and periodicals, and supports research in performance improvement in the workplace.
Software is a collection of programs and data that tell a computer how to perform specific tasks. Software often includes associated software documentation.[1] 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 that should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed to "jump" to a different instruction or is interrupted by the operating system. As of 2024, most personal computers, smartphone devices, and servers have processors with multiple execution units, or multiple processors performing computation together, so computing has become a much more concurrent activity than in the past.The majority of software is written in high-level programming languages for example Python, JavaScript, Visual Basic, Delphi, Perl, PHP, ECMAScript, Ruby, C#, and Java. They are easier and more efficient for programmers because they are closer to natural languages than machine languages.[2] High-level languages are translated into machine language using a compiler, an interpreter, or a combination of the two. Software may also be written in a low-level assembly language, for example C, C++, Assembly, and Fortran. Assembly languages have a strong correspondence to the computer's machine language instructions and are translated into machine language using an assembler.
HistoryMain article: History of softwareAn algorithm for what would have been the first piece of software was written by Ada Lovelace in the 19th century, for the planned Analytical Engine.[3] She created proofs to show how the engine would calculate Bernoulli numbers.[3] Because of the proofs and the algorithm, she is considered the first computer programmer.[4][5]The first theory about software, prior to the creation of computers as we know them today, was proposed by Alan Turing in his 1936 essay, On Computable Numbers, with an Application to the Entscheidungsproblem (decision problem).[6] This eventually led to the creation of the academic fields of computer science and software engineering; both fields study software and its creation.[7] Computer science is the theoretical study of computer and software (Turing's essay is an example of computer science), whereas software engineering is the application of engineering principles to development of software.[8]In 2000, Fred Shapiro, a librarian at the Yale Law School, published a letter revealing that John Wilder Tukey's 1958 paper "The Teaching of Concrete Mathematics"[9][10] contained the earliest known usage of the term "software" found in a search of JSTOR's electronic archives, predating the Oxford English Dictionary's citation by two years.[11] This led many to credit Tukey with coining the term, particularly in obituaries published that same year,[12] although Tukey never claimed credit for any such coinage. In 1995, Paul Niquette claimed he had originally coined the term in October 1953, although he could not find any documents supporting his claim.[13] The earliest known publication of the term "software" in an engineering context was in August 1953 by Richard R. Carhart, in a Rand Corporation Research Memorandum.[14]

TypesSee also: Software categoriesBlender, a free software programOn virtually all computer platforms, software can be grouped into a few broad categories.Purpose, or domain of useBased on the goal, computer software can be divided into:Application software uses the computer system to perform special functions beyond the basic operation of the computer itself. There are many different types of application software because the range of tasks that can be performed with a modern computer is so large—see list of software.System software manages hardware behaviour, as to provide basic functionalities that are required by users, or for other software to run properly, if at all. System software is also designed to provide a platform for running application software,[15] and it includes the following:Operating systems are essential collections of software that manage resources and provide common services for other software that runs "on top" of them. Supervisory programs, boot loaders, shells and window systems are core parts of operating systems. In practice, an operating system comes bundled with additional software (including application software) so that a user can potentially do some work with a computer that only has one operating system.Device drivers operate or control a particular type of device that is attached to a computer. Each device needs at least one corresponding device driver; because a computer typically has at minimum at least one input device and at least one output device, a computer typically needs more than one device driver.Utilities are computer programs designed to assist users in the maintenance and care of their computers.Malicious software, or malware, is software that is developed to harm or disrupt computers. Malware is closely associated with computer-related crimes, though some malicious programs may have been designed as practical jokes.
Nature or domain of executionDesktop applications such as web browsers and Microsoft Office and LibreOffice and WordPerfect, as well as smartphone and tablet applications (called "apps").[16]JavaScript scripts are pieces of software traditionally embedded in web pages that are run directly inside the web browser when a web page is loaded without the need for a web browser plugin. Software written in other programming languages can also be run within the web browser if the software is either translated into JavaScript, or if a web browser plugin that supports that language is installed; the most common example of the latter is ActionScript scripts, which are supported by the Adobe Flash plugin.[17]Server software, including:Web applications, which usually run on the web server and output dynamically generated web pages to web browsers, using e.g. PHP, Java, ASP.NET, or even JavaScript that runs on the server. In modern times these commonly include some JavaScript to be run in the web browser as well, in which case they typically run partly on the server, partly in the web browser.[18]Plugins and extensions are software that extends or modifies the functionality of another piece of software, and require that software be used in order to function.[19]Embedded software resides as firmware within embedded systems, devices dedicated to a single use or a few uses such as cars and televisions (although some embedded devices such as wireless chipsets can themselves be part of an ordinary, non-embedded computer system such as a PC or smartphone).[20] In the embedded system context there is sometimes no clear distinction between the system software and the application software. However, some embedded systems run embedded operating systems, and these systems do retain the distinction between system software and application software (although typically there will only be one, fixed application which is always run).[21][22][23]Microcode is a special, relatively obscure type of embedded software which tells the processor itself how to execute machine code, so it is actually a lower level than machine code.[24] It is typically proprietary to the processor manufacturer, and any necessary correctional microcode software updates are supplied by them to users (which is much cheaper than shipping replacement processor hardware). Thus an ordinary programmer would not expect to ever have to deal with it.[citation needed]
