sound carrier in a TV signal, the FM carrier that transmits the audio part of the program. sound velocity profile (SVP) description of the speed of sound in water as a function of water depth. source (1) refers to the signal generator/device that generates the RF, microwave, or micromilliwatt frequencies. (2) the terminal of a FET from which electrons flow (electrons in the FET channel flow from the source, and current flow is always in the negative direction of electron movement, since electrons are negative). It is usually considered to be the metal contact at the surface of the die. source code (1) software code written in a form or language meant to be understood by programmers. Must be translated to object code in order to run on a computer. (2) a set of codewords used to represent messages, such that redundancy is removed, in order to require less storage space or transmission time.

Software Version Control. Version control, also called revision or source control, involves the management of changes to source code, documentation and other collections of information. It is an important component of Software Configuration Management because it is common for multiple versions of the same software, or documentation, to be deployed in different sites and for Software Developers to be working simultaneously on multiple version updates. Errors or features of the software may only be present in certain versions, so it is important to be able to retrieve and run different versions of the software to determine in which version(s) the problems occur.

Software applications are packed into projects with support for more than one platform. Projects also integrate source code, compiled libraries (static and dynamic), intermediate representations (i.e., assembly code), and configuration data. Intermediate files are checked for consistency with respect to other elements in the project, providing automatic recompilation of the code when some portions they depend on are changed. For user-defined information, such as source code, version control may be activated, allowing programmers to keep control of the changes, backtrack to former versions, or issue versions and releases of the code.

Source code is a computer command written in a computer programming language for people to read. Often source code is a high-level representation of computer commands that must be assembled, interpreted or compiled before the computer can execute the code as a program (National Institute of Standards and Technology (NIST), 2018). Open-source technology originates from the open-source movement, which has accompanied the development of the entire computer industry and technology, and its application is mainly divided into free software and open-source software (Hongmin et al., 2007). In recent years, the number and types of smartphone applications are increasing. By using existing open-source technologies, smartphone applications have been able to serve as powerful platform terminals to provide technical support for all aspects of public production and life (De Sherbinin et al., 2021), such as a smart home. With the continuous advancement and development of the era of intelligence, the smartphone as the key to ‘all things intelligent’ will gradually become a reality.

Validating software involves a variety of activities that fall into two broad categories: those that involve static analysis of software artifacts and those that involve dynamic analysis of software artifacts (see Adrion, Branstad, and Cherniavsky 1982). We use the term software artifact to refer to byproducts of the software development process, such as requirements documents, source code, test cases, and documentation. Static analysis activities involve the examination of such artifacts, either manually or automatically. A code review is an example of a static analysis activity, where a group of software engineers examine source code to identify potential problems with the implementation. Dynamic analysis activities are different, in that they require the execution of a software artifact for a set of inputs and the resulting behavior of the artifact is what is examined. Software testing is an example of a dynamic analysis activity and the primary focus of this paper.
