Differentiate between dial-up and ADSL?
Answers
Answer:
Dial-up connections
Dial-up connections have been the most common type of internet connection available from ISPs but they are also the slowest and usually the most expensive.
A dial-up connection allows you to connect to the internet via a local server using a standard 56k modem, your PC literally dials (hence the name) a phone number (provided by your ISP) and connects to the server and therefore the internet.
Dial-up connection Pros
None.
Dial-up connection Cons
Dial-up connections are very slow compared to other connection types. When connected to the internet the same phone line cannot be used for phone calls so if anyone phones you when you are connected they will get the busy signal. In other word's it is Obsolete Technology
ADSL connections
ADSL (Asymmetric Digital Subscribers Line) connections are increasingly available and can provide an excellent internet connection.
The connections work by splitting your phone line into two separate channels, one for data (internet) and one for voice (phone calls) which means you can talk on the phone and be connected to the internet at the same time.
ADSL connection Pros
The download speed of pages is considerably faster than dial-up. ADSL technology eliminates the need for a second phone line by allowing voice and data transfer at the same time. ADSL connections are ‘Always on', which makes the usual long wait to connect a thing of the past.
ADSL connection Cons
ADSL connections are not available to everyone, you should always ensure that you have ADSL coverage in your area (an ISP will check for you).
