FAQ'S Of Software Testing

Q138. What is the difference between user documentation and user manual?
A: When a distinction is made between those who operate and use a computer system for its intended purpose, a separate user documentation and user manual is created. Operators get user documentation, and users get user manuals.
Q139. What is user friendly software?
A: A computer program is user friendly, when it is designed with ease of use, as one of the primary objectives of its design.
Q140. What is a user friendly document?
A: A document is user friendly, when it is designed with ease of use, as one of the primary objectives of its design.
Q141. What is a user guide?
A: User guide is the same as the user manual. It is a document that presents information necessary to employ a system or component to obtain the desired results. Typically, what is described are system and component capabilities, limitations, options, permitted inputs, expected outputs, error messages, and special instructions.
Q142. What is user interface?
A: User interface is the interface between a human user and a computer system. It enables the passage of information between a human user and hardware or software components of a computer system.

Q143. What is a utility?
A: Utility is a software tool designed to perform some frequently used support function. For example, a program to print files.
Q144. What is utilization?
A: Utilization is the ratio of time a system is busy, divided by the time it is available. Uilization is a useful measure in evaluating computer performance.
Q145. What is V&V?
A: V&V is an acronym for verification and validation.
Q146. What is variable trace?
A: Variable trace is a record of the names and values of variables accessed and changed during the execution of a computer program.
Q147. What is value trace?
A: Value trace is same as variable trace. It is a record of the names and values of variables accessed and changed during the execution of a computer program.
Q148. What is a variable?
A: Variables are data items whose values can change. For example: "capacitor_voltage". There are local and global variables, and constants.
Q149. What is a variant?
A: Variants are versions of a program. Variants result from the application of software diversity.
Q150. What is verification and validation (V&V)?
A: Verification and validation (V&V) is a process that helps to determine if the software requirements are complete, correct; and if the software of each development phase fulfills the requirements and conditions imposed by the previos phase; and if the final software complies with the applicable software requirements.

Q151. What is a software version?
A: A software version is an initial release (or re-release) of a software associated with a complete compilation (or recompilation) of the software.
Q152. What is a document version?
A: A document version is an initial release (or complete a re-release) of a document, as opposed to a revision resulting from issuing change pages to a previous release.
Q153. What is VDD?
A: VDD is an acronym. It stands for "version description document".
