A modular package containing a radio-frequency (r f ) amplifier and any associated cryogenic systems, routers and converters (mixers), whose input is the voltage from a receptor and whose output is an intermediate-frequency (i f ) signal In some antenna systems, a feed and associated receptors are also packaged with a front end module, in an integrated front end box See also local oscillator
In a computer network, this specialized pre-processor relieves a host computer of a task such as line control, message handling, code conversion, or error control "'Front end" could also refer to a specific system that is placed in front of another system, such as a voice prompting unit in front of a PBX-ACD unit
In the client/server model, the front-end part refers to the client side; it's where the user views and interacts with information from a server; for the Web, browsers provide the front end that communicates with Web servers on the back end FTP (File Transfer Protocol): The common procedure used for downloading and uploading files over the Internet With FTP you can login to another Internet site and transfer (meaning, send or receive) files Some sites have public file archives that you can access by using FTP with the account name "anonymous" and your e-mail address as the password This type of access is called anonymous FTP Macintosh owners use a program called Fetch; one of the best FTP programs for Windows is called WS-FTP
The first radio-frequency amplifier stage in a receiver One of the most critical components of the receiver because the sensitivity of the front end dictates the sensitivity of the entire receiver
The user interface that appears on a Web page and allows a visitor to the site to interact with dynamic features, including databases, shopping cart programs, and online purchase processing software
The client part of a client/server application that requests services across a network from a server, or back end It typically provides an interactive interface to the user, for example, a data entry front end, allowing data to be entered into a server through the use of SQL
When used with database management systems, an application, a window, or a set of windows by which the user may access and view database records, as well as add to or edit them
In Komag's manufacturing process, the front end is the initial process that includes the sizing and polishing of substrates, and the subsequent nickel plating and polishing of such substrates
