CLFI name for a Digital Signal 1 (DS1) a transmission line with bandwidth sufficient to carry 24 DS0 (64 or 56 Kbps depending on coding) channels.

Because of overhead a T1 being delivered by a provider for data communications usually provides 1.344Mbps of bandwidth, whereas the T1 consumes 1.544Mbps of bandwidth. With B8ZS coding the T1 can provide 1.536MBps of bandwidth (this has become common in modern networks)

The T1 was frequently thought of as the basic building block in Telecommunic...

It usually consists of a metallic conductor pattern on an epoxy glass composite insulating substrate, more complex circuits have several layers stacked togeather. After assembly where components are added, it is known as a printed wiring assembly (PWA).  

A compressed graphics format specifically designed for photographs. It´s name an acronym that stands for Joint Photographic Experts Group. It works by changing the images data from colours to frequencies (that represent detail) using a FFT and then discarding some of the high detail data - the resulting image is slightly blurry but this is barely noticable by the human eye and represents a significant saving of space.

A protocol developed to enable the transfer of files across a network. It provides a reletively insecure username and password  security but has been more recently enhanced to allow for SSL encryption to provide a secure password exchange.

To some extent the use of FTP has been superceeded by SFTP (a component of SSH) or the secure file transfer protocol.

A compressed graphic format suited for flat color images (illustrations) and drawings. It compresses images by referencing areas of the same colour thus it is less suitable then JPEG for photographic images (where there are colour gradients)

Originally created by CompuServ it was the subject of proposed law suits and patent discussions which have largely been dropped.
