Active Recovery Site
Active recovery site is used to recover data that involves two sites and which can take over the workload of others during a disaster.

Active Rendering
Active rendering may be a sort of programming that permits Java code to handle all of the renderings during an easy whereas loop. This approach resembles ancient game programming, permitting longer to be spent developing a game, and few times spent worrying concerning that painting technique to override.

Active Response
The ability to mechanically block the information processing address of an acknowledged unwelcome person for a particular quantity of your time. The amount of time that a Protection Agent blocks an intruder’s IP address can be modified to any interval from 1 to 65,000 seconds. There are two methods that the IDS can take to circumvent an attack. The first method of circumventing attacks would be Session disruption, and the second is Filter rule manipulation.

Activity Diagram
Activity diagram square measure graphical representations of workflows of stepwise activities and actions with support for alternative, iteration, and concurrency. In the Unified Modeling Language, activity diagram square measure meant to model each procedure and organizational processes (i.e. workflows). An activity diagram shows the overall flow of control.

Address Bus
An address bus may be a laptop bus (a series of lines connecting 2 or additional devices) that's wont to specify a physical address. When a processor or DMA-enabled device must browse or write to a memory location, it specifies that memory location on the address bus (the price to browse or written is sent on the data bus). The breadth of the address bus determines the quantity of memory a system will address. For example, a system with a 32-bit address bus will address 232 (4,294,967,296) memory locations. If every memory address holds one computer memory unit, the addressable memory space is 4 GB.

Address Mapping
A connected alternative is that the graininess of address mapping, which is defined as the smallest unit of address data (from the persistent store) that can be mapped independently to an area of the virtual address area. To a first approximation, this is a virtual memory page in Texas because any page of persistent data can be mapped into any arbitrary page of the virtual address house of a method. A major benefit of page-wise mapping is the savings in table sizes, we only need to maintain tables that contain mappings from persistent to virtual addresses and vice versa on a page wise basis, instead of (much larger) tables for recording the locations of individual objects. This reduces each the area and time prices of maintaining the address translation data.

Addressing
A name or variety employed in data storage or retrieval that's assigned to a particular memory location. The memory location is known by this name or variety. A name or a sequence of characters that designates an e-mail account or a specific site on the Internet or another network.
