- View
- A stored query. If you have a complex query that you have to run every week, you (or a database specialist) could create the query and save it as a view with its own name. It is then treated much like a simple table.
- Visual table of contents

- Software that tracks changes made to other documents. Often used in software development to enable developers to go back to prior version.

- Video
- One of the basic data types. Video combines the attributes of images and sound. An important attribute is the frames-per-second definition. U.S. standard video operates at 30 frames-per-second, movie films run at 24 frames-per-second. Digitizing video requires capturing and playing back the frames at the appropriate speed.
- Voice mail
- A messaging system similar to telephone answering machines but with additional features like message store and forward. You can use your computer to send messages to co-workers. There are tools that will read e-mail and fax messages over the phone, so managers can stay in touch while they are away from the computer.
