Hypothesis

hypotheseshypotheticalhypothesized
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used synonymously, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research, in a process beginning with an educated guess or thought.

A/B testing

A/B testssplit testingA/B test
A/B testing (bucket tests or split-run testing) is a randomized experiment with two variants, A and B. It includes application of statistical hypothesis testing or "two-sample hypothesis testing" as used in the field of statistics. A/B testing is a way to compare two versions of a single variable, typically by testing a subject's response to variant A against variant B, and determining which of the two variants is more effective.

Resident monitor

monitormonitor program resident software
In computing, a resident monitor is a type of system software program that was used in many early computers from the 1950s to 1970s. It can be considered a precursor to the operating system. The name is derived from a program which is always present in the computer's memory thus being "resident". Because memory was very limited on these systems the resident monitor was often little more than a stub which would gain control at the end of a job and load a non-resident portion to perform required job cleanup and setup tasks.

Engineer

engineersconsulting engineerIr.
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build, and test machines, systems, structures and materials to fulfill objectives and requirements while considering the limitations imposed by practicality, regulation, safety, and cost. The word engineer (Latin ingeniator ) is derived from the Latin words ingeniare ("to create, generate, contrive, devise") and ingenium ("cleverness").

Hacker

hackinghackershack
A computer hacker is any skilled computer expert that uses their technical knowledge to overcome a problem. While "hacker" can refer to any skilled computer programmer, the term has become associated in popular culture with a "security hacker", someone who, with their technical knowledge, uses bugs or exploits to break into computer systems.

Hypervisor

hypervisorsvirtual machine monitorhost machine
A hypervisor or virtual machine monitor (VMM) is computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine.

A web developer is a programmer who specializes in, or is specifically engaged in, the development of World Wide Web applications, or applications that are run over HTTP from a web server to a web browser.

Web design

web designerwebsite designdesign
Web design encompasses many different skills and disciplines in the production and maintenance of websites. The different areas of web design include web graphic design; interface design; authoring, including standardised code and proprietary software; user experience design; and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all. The term web design is normally used to describe the design process relating to the front-end (client side) design of a website including writing markup. Web design partially overlaps web engineering in the broader scope of web development.

Utility software

utilityutilitiessoftware utility
Utility software is system software designed to help to analyze, configure, optimize or maintain a computer. It is used to support the computer infrastructure - in contrast to application software, which is aimed at directly performing tasks that benefit ordinary users. Utilities often form part of application however. For example a batch job may run user-written code to update a database and may then include a step that runs a utility to back up the database, or a job may run a utility to compress a disk before copying files.

Control unit

The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic and logic unit and input and output devices how to respond to the instructions that have been sent to the processor.

Chief executive officer

CEOmanaging directorchief executive
The chief executive officer (CEO), or just chief executive (CE), is the most senior corporate, executive, or administrative officer in charge of managing an organization especially an independent legal entity such as a company or nonprofit institution. CEOs lead a range of organizations, including public and private corporations, non-profit organizations and even some government organizations (e.g., Crown corporations). The CEO of a corporation or company typically reports to the board of directors and is charged with maximizing the value of the entity, which may include maximizing the share price, market share, revenues, or another element.

Securities regulation in the United States

securities lawsecuritiesfederal securities laws
Other laws passed since then include Private Securities Litigation Reform Act (1995), Sarbanes–Oxley Act (2002), Jumpstart Our Business Startups Act (2012), and various other. Although practitioners in this area use these popular names to refer to the federal securities laws, like many U.S. statutes these laws are generally codified in the U.S. Code, the official codification of U.S. statutory law. They are contained in Title 15 of the U.S. Code. Thus, for example, the official code citation for Section 5 of the Securities Act of 1933 is 15 U.S.C. section 77e. Not every law adopted by Congress is codified, because some are not appropriate for codification.

Ed (text editor)

eded (programming language)ed editor
(pronounced as distinct letters, ) is a line editor for the Unix operating system. It was one of the first parts of the Unix operating system that was developed, in August 1969. It remains part of the POSIX and Open Group standards for Unix-based operating systems, alongside the more sophisticated full-screen editor vi.

Regulation D (SEC)

Regulation DGeneral SolicitationReg D
In July 2013, the SEC issued new regulations as required by 2012 Jumpstart Our Business Startups Act. These new regulations add Rule 506(c) to allow general solicitation and advertising for a private placement offering. However, in a Rule 506(c) private offering all of the purchasers must be accredited investors and the issuer must take reasonable steps to determine that the purchaser is an accredited investor. Section 4(5) of the '33 Act exempts from registration offers and sales of securities to accredited investors when the total offering price is less than $5 million and no public solicitation or advertising is made.

The U.S. Securities and Exchange Commission (SEC) is an independent agency of the United States federal government. The SEC holds primary responsibility for enforcing the federal securities laws, proposing securities rules, and regulating the securities industry, the nation's stock and options exchanges, and other activities and organizations, including the electronic securities markets in the United States.

Assembly language

assemblerassemblyassembly code
The Electronic Delay Storage Automatic Calculator (EDSAC) had an assembler (named "initial orders") integrated into its bootstrap program that used one-letter mnemonics in late 1948 developed by David Wheeler and credited by the IEEE Computer Society as the creator of the first "assembler." Reports on the EDSAC introduced the term "assembly" for the process of combining fields into an instruction word. SOAP (Symbolic Optimal Assembly Program) was an assembly language for the IBM 650 computer written by Stan Poley in 1955.

Self-efficacy

self efficacyefficacypersonal change
Self-efficacy is an individual's belief in their innate ability to achieve goals. Albert Bandura defines it as a personal judgement of "how well one can execute courses of action required to deal with prospective situations". Expectations of self-efficacy determine whether an individual will be able to exhibit coping behavior and how long effort will be sustained in the face of obstacles. Individuals who have high self-efficacy will exert sufficient effort that, if well executed, leads to successful outcomes, whereas those with low self-efficacy are likely to cease effort early and fail.

Graphical user interface

GUIgraphicalgraphical interface
The graphical user interface (GUI ) is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, instead of text-based user interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.

Stressor

Integrated development environment

IDEIDEsdevelopment environment
An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools, and a debugger. Most of the modern IDEs have intelligent code completion. Some IDEs, such as NetBeans and Eclipse, contain a compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not. The boundary between an integrated development environment and other parts of the broader software development environment is not well-defined.

Hoodie

A hoodie (also spelled hoody) is a sweatshirt or a jacket with a hood. Hoodies often include a muff sewn onto the lower front, and (usually) a drawstring to adjust the hood opening.

High-level programming language

high-levelhigh-level languagehigh level language
In computer science, a high-level programming language is a programming language with strong abstraction from the details of the computer. In contrast to low-level programming languages, it may use natural language elements, be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. memory management), making the process of developing a program simpler and more understandable than when using a lower-level language. The amount of abstraction provided defines how "high-level" a programming language is.

Sneakers

Sneakers (also known as athletic shoes, tennis shoes, gym shoes, sport shoes, runners, or trainers) are shoes primarily designed for sports or other forms of physical exercise, but which are now also widely used for everyday wear. The term generally describes a type of footwear with a flexible sole made of rubber or synthetic material and an upper part made of leather, synthetic substitutes or cloth.

Billiard table

pool tablepool tablessnooker table
A billiard table or billiards table is a bounded table on which cue sports are played. In the modern era, all billiards tables (whether for carom billiards, pocket billiards, pyramid or snooker) provide a flat surface usually made of quarried slate, that is covered with cloth (usually of a tightly-woven worsted wool called baize), and surrounded by vulcanized rubber cushions, with the whole elevated above the floor. More specific terms are used for specific sports, such as snooker table and pool table, and different-sized billiard balls are used on these table types. An obsolete term is billiard board, used in the 16th and 17th centuries.
