| RAID | Redundant Array of Independent Disks (variant redundant array of inexpensive disks) – technology that employs the simultaneous use of two or more hard disk drives to achieve greater levels of performance, reliability, and/or larger data volume sizes. The phrase “RAID” is an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives. RAID’s various designs all involve two key design goals: increased data reliability and increased input/output performance. When several physical disks are set up to use RAID technology, they are said to be in a RAID array. This array distributes data across several disks, but the array is seen by the computer user and operating system as one single disk. RAID can be set up to serve several different purposes. |

| RBI | Runs Batted In – A Run Batted In occurs when a player’s batted ball results in another player crossing the plate. For a HR, the hitter would also receive a RBI because he bats himself in.

| VIRTUAL STUDIO | A virtual studio is a television studio that allows the real-time combination of people or other real objects and computer generated environments and objects in a seamless, virtual reality-like manner. A key point of a virtual studio is that the real camera can move in 3D space, while the image of the virtual camera is being rendered in real-time from the same perspective. Most of them include Camera tracking, that uses either optical or mechanical measurements to create a live stream of data describing the exact perspective of the camera, realtime rendering software, that uses the camera tracking data and generates a synthetic image of a television studio, and A video mixer, which combines the video from the camera with the video from the realtime rendering software to produce a final video output. A major difference between a virtual studio and the bluescreen special effects used in movies is that the computer graphics are rendered in realtime, removing the need for any post production work, and allowing it to be used in live television broadcasts. |

| VPN | Virtual Private Network – A virtual private network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires. The link-layer protocols of the virtual network are said to be tunneled through the larger network when this is the case. One common application is secure communications through the public Internet, but a VPN need not have explicit security features, such as authentication or content encryption. VPNs, for example, can be used to separate the traffic of different user communities over an underlying network with strong security features.
