What Does Model View Controller (MVC) Mean? Model View Controller (MVC) is a design pattern for computer software. It can be considered an approach to distinguish between the data model, processing control and the user interface. It neatly separates the graphical interface displayed to the user from the code that manages the user actions. The objective is to provide a framework which enforces better and more accurate design. Techopedia Explains Model View Controller (MVC) MVC architecture helps to split applications into logical units....

What Does Name Resolution Mean? Name resolution, in the context of programming, is the linking of identifiers within the programming environment to the actual program components that they represent. These names may be stored in lookup tables or as part of a namespace hierarchy. The purpose of the naming is to provide a shorthand reference to coded material. The process may be used to call a function, variable or other component from a repository of named entities....

What Does Native Command Queuing (NCQ) Mean? Native command queuing (NCQ) is a technology enabling SATA hard drives to accept more than one command at a time by optimizing the order in which read and write commands are executed. This increases the performance of the drive by limiting the number of drive head movements when multiple read/write requests are queued. Techopedia Explains Native Command Queuing (NCQ) NCQ replaces tagged command queuing (TCQ), which is used with parallel ATA (PATA)....

What Does Object-Oriented Programming (OOP) Mean? Object-oriented programming (OOP) is a software programming model constructed around objects. This model compartmentalizes data into objects (data fields) and describes object contents and behavior through the declaration of classes (methods). Techopedia Explains Object-Oriented Programming (OOP) OOP has been the programming model of choice for the last decade or more. OOP’s modular design enables programmers to build software in manageable chunks rather than in large amounts of sequential code....

What Does Offsite Data Protection Mean? Offsite data protection is the process of storing and protecting backup data on an external/offsite backup storage device or facility. It is similar to data backup or offsite data backup techniques that secure and protect data at rest at an offsite location. Offsite data protection is also known as vaulting. It is also sometimes known as offsite data backup, whereas offsite data protection adds security processes within the backup process, offsite data backup is used only to store/backup data....
