The separation of software systems into "front-ends" and "back-ends" is an abstraction that keeps the different parts of the system separated.īS Contact was designed as front end-Software, to visualize 3D-images on the users Client (PC) using data of a backend-system, supplied by e.g. VRML ( Virtual Reality Modeling Language is a standard file format for representing 3-dimensional (3D) interactive vector graphics, designed particularly with the World Wide Web in mind.īS Contact supports several formats of open standards like the ISO Standard Format VRML/X3D or Khronos Format Collada as well as KMZ.įrontend In software design, the front-end is the part of a software system that interacts directly with the user, and the back-end comprises the components that process the output from the front-end. These dumb terminals were clients of the time-sharing mainframe computer. The term was first applied to devices that were not capable of running their own stand-alone programs, but could interact with remote computers via a network. BS Encrypt uses Checksum-Conceps to protect 3D contents.Ĭlient is an application or system that accesses a remote server to collect data from an another computer by way of a network. It works by adding up the basic components of a message, typically the asserted bits, and storing the resulting value. Ĭhecksum is a form of redundancy check, a simple way to protect the integrity of data by detecting errors in data that are sent through space or time. Some CDs hold both computer data and audio with the latter capable of being played on a CD player, whilst data (such as software or digital video) is only usable on a computer such as enhanced PC CD-ROMs.Ĭhat Online chats refer to any kind of real time communication over the Internet, but are primarily meant to refer to direct one-on-one chat or text-based group chat (formally also known as synchronous conferencing), using tools such as instant messaging, Internet Relay Chat, talkers. CD-ROMs are popularly used to distribute computer software, including games or multimedia applications, though any data can be stored (up to the capacity limit). Tracking Systems support navigation within 3-dimensional images.ĬD-ROM Compact Disc- Read- Only Memory is a Compact Disc that contains data accessible by a computer. Many 3D displays use this method to convey images. The illusion of depth in a photograph, movie, or other two-dimensional image is created by presenting a slightly different image to each eye. With these glasses, used in the CAVE people can actually see objects floating in the air, can walk around them to get a proper view of what the object would look like in reality. In a cave the user wears special glasses to see the 3-D graphics generated by the CAVE. ![]() If a user revisits a Web page after only a short interval, the page data may not need to be re-obtained from the Web server.Ĭave is an acronym for immersive virtual reality environment where projectors are directed to three, four, five or six of the walls of a room-sized cube. Once the data is stored in a cache, future use can be made by accessing the cached copy rather than re-computing the original data, reducing the average access time considerably. The term octet is widely used, where ambiguity is neglected.Ĭache is a temporary storage area, where frequently accessed data can be stored for rapid access. In some computer architectures it is a unit of memory addressing. ![]() Microcomputers based on 8-bit processors have made eight bits the most common size for a byte. Good examples include Amway and Mary Kay.īyte (see also binary digits) is a collection of bits and a unit of measurement for digital information storage, mostly consisting of eight bits. Multi-Level Network-Marketing (MLNM) : Assigned affiliates recommend a shopping and business opportunity to other consumers and turn their daily expenditures into regular income due to a scheme of profit sharing between a pool of manufacturers and a world-wide growing network of consumers doing tue same BUZZ-business.
