What is the diff. between ADSL and DSL?

Answer 1

Hi, here's the answer

Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional modem can provide.

For conventional ADSL, downstream rates start at 128 kbit/s (though a minimum offering of 512 kbit/s is more common) and typically reach 8 Mbit/s within 1.5 km (5000 ft) of the DSLAM equipped central office or remote terminal. Upstream rates start at 64 kbit/s and typically reach 128 kbit/s or 256 kbit/s but can go as high as 1024 kbit/s. The name ADSL Lite is sometimes used for the slower versions.

Answer 2

There are many different technology versions of DSL. DSL (Digital Subscriber Line) is just an acronym that Internet Service Providers - i.e. Bellsouth, AT&T, etc. use to not confuse the consumer. ADSL (Asymmetric Digital Subscriber Line) is 1 of the various versions of the technology. I don't know how much you know about computers, but to best describe it to you. All forms of DSL are capable of providing a high-speed "always-on" connection, but go about it different ways. For example, with ADSL is asymmetric and therefore uses most of the channel to transmit downstream (download) to the user and only a small part to receive (upload) information from the user. ADSL simultaneously accommodates analog (voice - i.e. your landline phone service) information on the same line. ADSL is generally offered at downstream data rates from 512 Kbps to about 6 Mbps.

Answer 3

Asymmetrical DSL
Most homes and small business users are connected to an asymmetric DSL (ADSL) line. ADSL divides up the available frequencies in a line on the assumption that most Internet users look at, or download, much more information than they send, or upload. Under this assumption, if the connection speed from the Internet to the user is three to four times faster than the connection from the user back to the Internet, then the user will see the most benefit (most of the time).

Answer 4

The A in adsl stands for anti symmetric, all it means is that the upload speed is not the same as the downlaod speed ( its slower) and this is fine for most home users since downloading is mostly what you need.
Anti symmetric cause the up and down speed as different

Answer 5

ADSL=Asynchronous Data Subscriber Line
Almost all of these connections are actuallu ADSL, but the term has been shortened over time.

Answer 7

You need to know the the acronym stands for

DSL = digital subscriber line
ADSL = asymmetrical digital subscriber line
SDSL = symmetrical digital subscriber line

DSL is just a generic term for high speed Internet

the A in front tells you that the upload and download speeds are not equal.

an S in front tells you the upload and download speeds are equal.

Answer 8

For the most part they mean the same thing. Check out this site for more details.

Answer 9

i've never heard of ADSL. but i heard of DSL...actually, i have DSL. [Bellsouth FastAccess DSL is what i have]
