Authentication
Authentication real or genuine, from authentes; author) is the act of establishing or confirming something (or someone) as authentic, that is, that claims made by or about the thing are true. Authenticating an object may mean confirming its provenance, whereas authenticating a person often consists of verifying their identity. Authentication depends upon one or more authentication factors.
The standard music file format for Windows operating systems. (It is also called WAV format.) Typically, WAV files consist of PCM data in 8 or 16-bit monaural or stereo format.
Backup
In information technology, backup refers to making copies of data so that these additional copies may be used to restore the original after a data loss event. These additional copies are typically called "backups." Backups are useful primarily for two purposes. The first is to restore a computer to an operational state following a disaster (called disaster recovery). The second is to restore small numbers of files after they have been accidentally deleted or corrupted. Backups are typically that last line of defense against data loss, and consequently the least granular and the least convenient to use.
Indicates the amount of data processed per second. The rate is represented in bps (bits per second).
For example, 105 kbps for the bit rate means 105,000 bits of information per second. In 1AVCenter, you can select a format and bit rate used for recording tracks from an audio CD. The larger the bit rate, the more information is stored for the track. Comparing music files in the same format (such as ATRAC3 format), 105 kbps offers better sound quality than 66 kbps, and 132 kbps offers better sound quality than 105 kbps.
Note however, that music files in different formats (such as MP3) have different encoding methods, so sound quality cannot be determined by simply comparing bit rates.
Broadcast
Broadcasting is the distribution of audio and/or video signals which transmit programs to an audience. The audience may be the general public or a relatively large sub-audience, such as children or young adults.
Codec
A codec is a device or program capable of performing encoding and decoding on a digital data stream or signal. The word codec may be a combination of any of the following: 'Compressor-Decompressor', 'Coder-Decoder', or 'Compression/Decompression algorithm'.
Carbon copy (C.c.)
Carbon copying, often abbreviated to c.c., was originally the technique of using carbon paper to produce one or more copies simultaneously with the creation of paper documents. On a typewriter, this would be done by placing carbon paper sheets between two or more sheets of paper in the machine, so that whatever was typed on the front sheet was copied onto the other sheets. This technique applies to written documents as well.
Docs
Docs is an abbreviation for Documents.
Encoder
Windows Media Encoder is a production tool developed by Microsoft which enables content developers to convert both live and prerecorded audio, video, and computer screen images to Windows Media formats for live and on-demand delivery.
FTP
FTP or File Transfer Protocol is used to transfer data from one computer to another over the Internet, or through a network.
Specifically, FTP is a commonly used protocol for exchanging files over any network that supports the TCP/IP protocol (such as the Internet or an intranet).
Firewall
A firewall is a hardware or software device which is configured to permit, deny, or proxy data through a computer network which has different levels of trust.
[H]
HTTP
Hypertext Transfer Protocol (HTTP) is a communications protocol used to transfer or convey information on the World Wide Web. Its original purpose was to provide a way to publish and retrieve HTML hypertext pages.
JPG
JPEG (pronounced JAY-peg; IPA is a commonly used method of compression for photographic images. The name JPEG stands for Joint Photographic Experts Group, the name of the committee that created the standard. The group was organized in 1986, issuing a standard in 1992 which was approved in 1994 as ISO 10918-1. JPEG is distinct from MPEG (Moving Picture Experts Group) which produces compression schemes for video.
Look and feel
Look and feel is a term used in descriptions of products and fields such as marketing, branding and trade marking, to signify the experience a person has using a product, and the main features of its appearance and interfaces.
MP3, which stands for MPEG-1 Audio Layer-3, is a format standard for music file compression. It was codified by the Motion Picture Experts Group, a working group of ISO (International Organization for Standardization).
It compresses audio CD data to approximately one tenth its original size. Because the MP3 encoding algorithm has been made publicly available, there are various encoders and decoders that are compliant with this standard.
Panel
One of several objects in computer software (a widget or a control panel).
PCM, which stands for Pulse Code Modulation, is a method of encoding analog audio signals into digital form. For example, it is utilized for encoding digital audio for CDs (compact discs).
Port (Network Port)
In the TCP and UDP protocols used in computer networking, a port is a special number present in the header of a data packet. Ports are typically used to map data to a particular process running on a computer.
Ports can be readily explained with an analogy: think of IP addresses as the street address of an apartment building, and the port number as the number of a particular apartment within that building. If a letter (a data packet) is sent to the apartment (IP) without an apartment number (port number) on it, then nobody knows who it is for (which service it is for). In order for the delivery to work, the sender needs to include an apartment number along with the address to ensure the letter gets to the right domicile.
Profile
Profile, configuration settings and other data associated with an individual user or with a group.
Proxy
Proxy server, a computer network service that allows clients to make indirect network connections to other network services.
Recipient
A recipient is defined as an entity which receives a good or service. The entity can be a person, a group of persons, a company, an organization, or a government.
Screencast
A screencast is a digital recording of computer screen output, also known as a video screen capture, often containing audio narration. Although the term screencast dates from 2004, products such as Lotus ScreenCam were used as early as 1993. Early products produced large files and had limited editing features. More recent products support more compact file formats have more sophisticated editing features allowing changes in sequence, mouse movement, and audio.
SMTP
Simple Mail Transfer Protocol (SMTP) is the de facto standard for e-mail transmissions across the Internet. Formally SMTP is defined in RFC 821 (STD 10) as amended by RFC 1123 (STD 3) chapter 5. The protocol used today is also known as ESMTP and defined in RFC 2821.
Spy
Espionage (a loanword from French espionnage) or spying is a practice of obtaining information about an organization or a society that is considered secret or confidential without the permission of the holder of the information. Unlike other forms of intelligence work, espionage involves accessing the place where the desired information is stored, or accessing the people who know the information and will divulge it through some kind of subterfuge. It also can be used as a general term to describe spying activities.
Stealth
Technology used to conceal ships, aircraft, and missiles and in this case 1AVCenter.
Streaming
Streaming media, multimedia data transferred in a stream of packets that are interpreted and rendered, in real time, by a software application as the packets arrive.
Surveillance
Surveillance is the monitoring of behavior. Systems surveillance is the process of monitoring the behavior of people, objects or processes within systems for conformity to expected or desired norms in trusted systems for security or social control.
Theme
Theme (computing), a custom graphical appearance for certain software, similar to a skin
Toolbar
In a graphical user interface on a computer monitor a toolbar is a row, column, or block of onscreen buttons or icons that, when clicked, activate certain functions of the program. Earlier forms of toolbars were defined by the programmer and had set functions. Most modern programs and operating systems however, allow the end user to modify and customize toolbars to fit their personal needs. A prominent example of a customizable toolbar is the Microsoft Windows Taskbar; functions of which range from an expandable programs menu, task listing, system tray and clock.
Upload
Uploading and downloading are related terms used to describe the transfer of electronic data between two computers or similar systems. More colloquially, they are sometimes applied to transfers to/from removable media such as CDs.
Video Mail
Videomail, video mail and video email. is a short usually five second to ten minute, length, freshly recorded video sent to someone's email inbox. Usually a video mail is merely a link to the video which is streamed to the viewer from a video mail provider or host computer upon the viewers request.
The standard music file format for Windows operating systems. (It is also called WAV format.) Typically, WAV files consist of PCM data in 8 or 16-bit monaural or stereo format.
Webcast
A webcast is a media file distributed over the Internet using streaming media technology. As a broadcast may either be live or recorded, similarly, a webcast may either be distributed live or recorded. Essentially, webcasting is “broadcasting” over the Internet.
Web Server
A computer program that is responsible for accepting HTTP requests from clients, which are known as web browsers, and serving them HTTP responses along with optional data contents, which usually are web pages such as HTML documents and linked objects (images, etc.).
A technology that includes a content management system, called Windows Media Rights Manager that encrypts audio content and distributes it according to certain conditions of usage or distribution.
Wizard
A computer user interface that leads a user through dialog steps.
