Can you help me find the different transfer speeds for broadband, lan, isdn, adsl and telephone modem?
And maybe with some pics
and the url to prove it?
Answer
Broadband is a generic term referring to anything over 256k bandwidth.
lan - used to be 10mb, most commonly 100mb, 1gb now becoming more popular.
isdn (integrated services digital network) - 2 x 64k channels for isdn2. 30 x 64k channels for isdn30
adsl (asynchronous digital subscriber line) - this is a specific technical implementation of a broadband service. usually 256k upload speed, download speed can be 512k upwards, most commonly 2mb, although with adsl max "up to" 8mb
telephone modem - usually 56k in theory but closer to 42k in practice.
sdsl (synchronous digital subscriber line) is another variant of broadband, but has the same upload and download speed.
