Filename extension – Normally three or four letters at the end of the file name separated by a dot, denoting the file type. Hundreds of extensions are being used with new being invented daily. E.g. .txt (text file), .gif (Graphic Interchange Format) etc.
Firewire or IEE 1394 or i.Link - IEEE 1394 is the official name for communication standard between different electronic devices without data loss. FireWire is an Apple register mark, while i.Link is Sony’s.
- According to official specifications, this standard enables the connection of 63 digital devices. The maximum bandwidth is 400 Mbps. Digital TV devices can be connected on 200 Mbps connection speed.
- Market offers IEEE-1394 controllers and IEEE-1394 cable, which enable a simple connection of digital devices without having to convert the digital signal into analogue and back to digital again. This prevents quality loss of the signal. This method allows for a signal from a digital video camera to be directly, i.e. in a digital format, transferred to a computer, processed and stored on the appropriate medium.
Font – A group of characters and symbols which does not differ from other such characters by the meaning of the characters, but by their appearance, weight and size expressed in typographic dots.
Formats - MPEG (Moving Picture Expert Group) - . MPEG is included in the definition of standards for data compression of moving pictures. Their work is a continuation of JPEG – adding compression for removal of time redundancy, additional compression which is possible due to similarity of individual images in a sequence of images which make up a video signal. Initially four standards were planned, however with the integration of HDTV into MPEG-2 standard, MPEG-3 became redundant. TV industry is primarily interested in MPEG-1 and MPEG-2 standards, while MPEG-4 is used for different purposes. AVI (Audio-Video Interleaved, video and audio of a lower quality and compression level, compared to MPEG is a more often used Microsoft format – most computers use support for animations instead of animated .GIF images (advantage: more colours). WMV (Windows Media Video, newer Microsoft format designed for use on the Internet has a lower video quality and allows a small quantity of data). QuickTime (this technology uses HW compression for capturing, managing and saving a video, and SW compression for playing the video on the end user’s computer as a standardized format of a file for creation and playing of a video. Video with audio is recorded on one computer, and played on any computer with QuickTime. DIVX (holds the same position among video formats as MP3 does among music formats) is very popular for exchange of films over the Internet. It uses MPEG-4 technology.
Forward – Redirection of messages, sending the messages through the net.
Frame – Package in the layers of data connection consisting of header and other information necessary for data transfer. In HTML, a frame represents a part of the screen on which the data is displayed.
Freeware – Software which you are allowed to share for free with authors permission, but often having to comply to certain terms (such as that software cannot be altered etc.)
FTP - (File Transfer Protocol) is one of the main ways files are transferred over the Internet. An FTP page is a page which is provided by a certain company or organization as storage for different types of files that the users can download.
FTP mail – a procedure in which e-mail is used to access an FTP page.
