Dial-up connection
A dial-up connection allows users to connect to the internet via their telephone line using a standard 56k modem. The computer literally dials a telephone number provided by the Internet Service Provider and connects to the server's modem and therefore the internet. Dial-up has a transfer rate of 56 Kilobits of data per second under ideal conditions.
Advantages and disadvantages of Dial up Connection * Cheap (possibly even free in some areas) * Requires no new infrastructure (uses POTS telephone line) * Usually does not require the purchase of additional hardware / equipment
Disadvantages
* Slower than other forms of internet connectivity * Occupies the usage of the phone line * Possible long-distance charges if no ISP is in your area.
Broadband Connection (or High-Speed Internet)
Fast: Broadband operates from 10 to 20 times faster than a dial-up connection, enabling the speedy transfer of large amounts of data. For instance, downloading a song takes a few seconds versus perhaps ten minutes with dial-up; e-mailing digital photos is almost instantaneous.
Cost: Broadband subscribers usually pay a flat monthly fee, avoiding hourly usage charges; it should cost less for broadband than for a dial-up account.
Convenience: With broadband you have instant Internet access, 24/7, so you don't have to connect each time you want to go online--you're always connected. This makes it easy to access information when you need it, check your e-mail, and even make phone calls over the Internet. Also, multiple computers can
