Advanced Audio Coding, a “lossy” compression format capable of delivering relatively high quality at relatively low bit rates.
The Sun Appliance Link Protocol, a suite of network protocols that enable communication between Sun Ray servers and DTUs.
Context-adaptive binary arithmetic coding, a “lossless” entropy coding technique used in H.264/MPEG-4 AVC video encoding.
An earlier implementation of Sun Ray Server Software controlled access mode. The current implementation is known as kiosk mode.
Normally, this term refers both to the physical hardware, such as a Sun Ray thin client desktop unit, and the process that accesses resources such as compute power, memory, and applications from a server. The server may be located remotely or locally. In the present context, the Sun Ray DTU is a client of the Sun Ray server; the Sun Ray Windows Connector software is a Windows Terminal Server client.
A common way to describe network services and the user processes of those services. Although this term can apply to a wide range of interactions between desktops and larger computing facilities, the thin client model suggests that all, or nearly all, computing be performed on the server.
A device or program capable of encoding and/or decoding a digital data stream or signal.
The Sun Ray Data Store is a repository for information needed to administer several aspects of the Sun Ray Server Software, such as failover groups, for example. The Sun Ray Windows Connector utilizes it to store licensing information and printer preferences.
The capability for using applications located on a server to play audio files on a client. For example, .wmv files can be played on a remote Windows Terminal Server and heard on a Sun Ray DTU.
Sun Ray desktop units (originally known as Desktop Terminal Units).
A standard for video compression developed by MPEG and VCEG for a wide range of bit rates and resolutions. Also known as MPEG-4 AVC (Advanced Video Coding) and MPEG-4 Part 10.
The ability for a user to remove a smart card, insert it into any other DTU within a server group, and have the user’s session “follow” the user, thus allowing the user to have instantaneous access to the user’s windowing environment and current applications from multiple DTUs.
A facility to run sessions without UNIX login under an anonymous user account. Kiosk sessions provide a preconfigured, usually restricted, software environment. The term kiosk mode was used interchangeably with CAM in earlier versions of SRSS. As of SRSS 4.0, however, this module was completely rewritten and is now officially called kiosk mode. The term CAM is mean to refer to implementations in SRSS 3.1 and earlier.
Microsoft Point-to-Point Compression protocol.
A print queue enabled without a print driver having been specified. Instead of processing data before sending it to a printer, the lp utility sends raw, unprocessed data to the printer.
Microsoft Remote Desktop Protocol.
Generically defined as a network device that manages resources and supplies services to a client. This manual refers in particular to the Sun Ray server(s), which host Sun Ray sessions as well as DTUs, and to Windows Terminal Servers, which act as hosts for Windows applications that can be reached by RDP clients, of which the Sun Ray Windows Connector is an example. The Sun Ray DTU is a client of the Sun Ray server; the Sun Ray Windows Connector is a Windows Terminal Server client.
A cluster of servers linked with load balancing software.
For the purposes of the Sun Ray Server Software, any application that can directly connect to the Sun Ray DTU. It can include audio, video, X servers, access to other machines, and device control of the DTU.
A group of services associated with a single user.
A database that keeps track of which users are running which sessions on which Windows Terminal Servers, which makes it possible for users to reconnect to their previously disconnected Windows sessions.
The ability for a session to “follow” a user’s login ID or a token embedded on a smart card.
The desktop unit, originally known as the desktop terminal unit, is the physical appliance used to transmit keystrokes and mouse events to and receive display information from the Sun Ray server. The Sun Ray DTU hardware has a built-in smart card reader, and most models also contain a flat-panel display.
The client software used to access remote sessions hosted on a Windows Terminal Server, in this case, the Sun Ray Windows Connector.
Thin clients remotely access some resources of a computer server, such as compute power and large memory capacity. Sun Ray DTUs rely on the server for all computing power and storage. Within the client-server computing model, thin clients are distinguished from fat clients by the absence of local operating systems, applications, disc drives, fans, or other devices that fat clients need in order to operate.
The capability for recording sound from the client to the server.
Uniform Resource Identifier, the generic term for all types of names and addresses that refer to objects on the World Wide Web.
Uniform Resource Locator, the global address of documents and other resources on the World Wide Web. A URL is a specific type of URI.
Simple, lossless mechanism to store images or a sequence of images.
Any device used to access Windows applications residing on a Windows Terminal Server.
A server that hosts Microsoft applications for remote terminals or clients.
Windows Media Audio data compression file format and codec developed by Microsoft.
The color encoding system used for analog television.
