What is software development?
Software development refers to a set of computing activities dedicated to the process of creating, designing, deploying, and supporting software.
El software en sí es el conjunto de instrucciones o programas que le dicen a una computadora qué hacer. Es independiente del hardware y hace que las computadoras sean programables. Hay tres tipos básicos:
System software to provide basic functions such as operating systems, disk management, services, hardware management, and other operational needs.
Programming software to provide programmers with tools such as text editors, compilers, linkers, debuggers, and other tools for creating code.
Application software (applications or apps) to help users perform tasks. Office productivity suites, data management software, media players, and security programs are a few examples. Apps also refers to web and mobile applications such as those used to shop on Amazon.com, socialize on Facebook, or post images on Instagram.
A possible fourth type is embedded software. Embedded systems software is used to control machines and devices not normally thought of as computers, such as telecommunication networks, automobiles, industrial robots, and more. These devices, and their software, can be connected as part of the Internet of Things (IoT).
Software development is mainly carried out by programmers, software engineers, and software developers. These roles interact and overlap, and the dynamics between them vary greatly across development departments and communities.
Programmers, or coders, write source code to program computers to perform specific tasks such as merging databases, processing online orders, routing communications, performing searches, or displaying text and graphics. Programmers often interpret instructions from software developers and engineers and use programming languages such as C++ or Java to carry them out.
Software engineers apply engineering principles to create software and systems to solve problems. They use modeling language and other tools to come up with solutions that can often be applied to problems in a general way, rather than just solving a specific instance or client. Software engineering solutions adhere to the scientific method and must work in the real world, such as with bridges or elevators. Their responsibility has increased as products have become increasingly intelligent with the addition of microprocessors, sensors, and software. Not only are more products relying on software to differentiate themselves from the competition in the marketplace, but their software development must be coordinated with mechanical and electrical product development work.
Software developers have a less formal role than engineers and may be closely involved in specific areas of the project, including writing code. At the same time, they drive the overall software development lifecycle by working in functional teams to transform requirements into functions, managing development teams and processes, and performing software testing and maintenance.
