In software engineering, performance testing is in general, a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload.

Static Testing, a software testing technique in which the software is tested without executing the code. This Techniques provide a powerful way to improve the quality and productivity of software development by assisting engineers to recognize and fix their own defects early in the software development process.

Statement coverage is a white box test design technique which involves execution of all the executable statements in the source code at least once. It is used to calculate and measure the number of statements in the source code which can be executed given the requirements.

Impact Analysis is used in software testing to define all the risks associated with any kind of changes in a product being tested.

Code review is a software quality assurance activity in which one or several humans check a program mainly by viewing and reading parts of its source code, and they do so after implementation or as an interruption of implementation.

For floating point numbers (float, double, long double) the values cannot be predicted exactly. Depending on the number of bytes, the precession with of the value represented varies. Float takes 4 bytes and long double takes 10 bytes. So float stores 0.9 with less precision than long double.

Functional testing is a type of testing that is done against the requirements of the business application. 

Configuration Management is a support for software in managing the different items in the product, and changes in them.

Sequential is the simplest file structure

Structural Testing is the other name for White Box Techniques.

Full binary tree loses its nature when operations of insertions and deletions are done. For incomplete binary trees, extra storage is required and overhead of NULL node checking takes place. So complete binary tree is the better one since the property of complete binary tree is maintained even after operations like additions and deletions are done on it.

BackTracking is used for solving N-Queens problem

Configuration management is not concerned with the choice of the hardware configuration for an application.

Data flow analysis studies the use of data on paths through the code.

Data Control Language takes caare of security and authorization

Component Testing is also called as Module or Unit or Program testing. It is testing of all the components in an application separately.
