Computer programmingComputer programming is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit.
Software engineeringSoftware engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintainingsoftware applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs. A software engineer applies a software development process to define, implement, test, manage, and maintain software systems.
Software bugA software bug is a defect (bug) in computer software. A computer program with many or serious bugs may be described as buggy. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing).
Source CodeSource Code is a 2011 science fictionaction thriller film directed by Duncan Jones and written by Ben Ripley. It stars Jake Gyllenhaal as a US Army officer who is sent into an eight-minute virtual re-creation of a real-life train explosion, and tasked with determining the identity of the terrorist who bombed it. Michelle Monaghan, Vera Farmiga, and Jeffrey Wright play supporting roles.
Artificial intelligenceIntelligence in machinesArtificial intelligence (AI) is the capability of computational systems to perform tasks typically associated with human intelligence, such as learning, reasoning, problem-solving, perception, and decision-making.

AlgorithmIn mathematics and computer science, an algorithm () is any well-defined set of instructions that when followed terminates after a finite number of steps that comprise a solution to a given computational problem. Advanced algorithms may utilize loops and involve many conditionals that decide the next step based on the inputs provided, resulting in long sequences of steps before halting, but all algorithms terminate by definition.
Code reviewCode review (sometimes referred to as peer review) is a software quality assurance activity in which one or more people examine the source code of a computer program, either after implementation or during the development process. The persons performing the checking, excluding the author, are called "reviewers". At least one reviewer must not be the code's author.
Software developmentSoftware development is the process of designing, creating, testing, and maintaining software applications to meet specific user needs or business objectives. The process is more encompassing than programming, writing code, because it includes conceiving the goal, evaluating feasibility, analyzing requirements, design, testing and release.AuthorIn legal discourse, an author is the creator of an original work that has been published, whether that work exists in written, graphic, visual, or recorded form. The act of creating such a work is called authorship, which means a sculptor, painter, or composer is considered the author of their respective sculptures, paintings, or musical compositions.
Job (role)A job, employment, work or occupation, is an activity, often regular and typically performed in exchange for payment ("for a living"). A person can begin a job by becoming an employee, volunteering, or starting a business. The duration of a job may range from temporary (e.g., hourly odd jobs) to a lifetime (e.g., judges). An activity that requires a person's mental or physical effort is work (as in "a day's work").
Specification (technical standard)A specification, colloquially spec, often refers to a set of documented requirements to be satisfied by a material, design, product, or service. A specification is often a type of technical standard. There are different types of technical or engineering specifications (specs), and the term is used differently in different technical contexts. They often refer to particular documents, and/or particular information within them.*As an Amazon Associate I earn from qualifying purchases.
