In Software Applications and Products defects (bugs) can be injected from different sources (causes) and during different phases of Software Development Life Cycle (SDLC). These defects sources can be derived from Software Requirements and Software Design rather than the Coding. Commonly Coding is known as main source of Defects in Software Applications and Products.
Software Quality Assurance (QA) means the Verification activities performed to control the defects in Softwares. Software QA involvement starts early in the Software Development Life Cycle (SDLC), right from the Project Planning and Requirement Analysis Phase. Software QA works on the idea of prevention of defects activities.
A bug is a defect in a Software Application. We can say that a bug is a condition when software does not perform what it should perform under normal circumstances.
