Computers such as networks, smartwatches and smartwatches vehicles, smartphones video games, and the countless apps that populate our daily lives – all depend on software in order to function. These digital products, and many more, are the creations of software developers, who are image source the creative masterminds who brainstorm for these software applications.

Software development is the process of taking the idea of a program from conception to its release. It is a methodical process which begins with a thorough requirements analysis. This transforms the needs of the user and wants into an operational software system. The Software Development Life Cycle (SDLC) provides the steps to follow in this process. Following this framework allows developers to create software with better quality lower cost and a shorter time to produce than other methods.

Testing is a crucial component of any software development project. It ensures that the software is free of errors and function in accordance with the specifications. Depending on the scope of the application the process may include functional regression, compatibility, load testing.

Performance testing is used to determine an application’s response time under normal and peak load conditions, and its capacity to scale. It assesses how an application responds to changes in the number of simultaneous users and transactions, as well as determining the capacity of the network or hardware required to host the application.

The need for software developers is growing as new technologies emerge that require complex programming. Internet of Things, in which devices such as homes, cars and industrial machines communicate via sensors and microprocessors. Also artificial intelligence-powered software lets software perform tasks such as emulating decision-making, and learning.
