As the Internet grows in popularity because of its versatility
and usefulness, choosing the right connection for accessing
it is becoming a very important decision. While modems still
despite of their slow connection but economic cost, DSL, cable,
ISDN, are becoming popular and are being introduced by many
organizations to take benefit of high-speed access.
Speed:
When you read an ad that says: "Our Connection Provides
You with an Amazing and Unbelievable 10 Megs per Second Download
Speed," you should be amazed, but maybe not as much as
you think. Some time back, a quick marketing person decided
that Internet connection speed would be better described in
bits, not the bytes usually used to describe disk size and
RAM space. So that "unbelievable" 10 Megabits per
second is actually about 1.25 megabytes per second. This article,
not to confuse things further, will continue to discuss Internet
speed in bits per second. So, don't jump out of your skin
the next time you read about another "unbelievable"
download speed. Simply divide by 8.
Types of Access:
Anyone who has used a modem knows the problems associated
with dial-up access. Even if you just want to check your email
for one minute, you have to wait a couple minutes for your
modem to dial a number and establish a connection to your
ISP. It often takes less time to check your email than it
does to connect the Internet! While this isn't a major problem
if you rarely use the Internet, it can be a major annoyance
if you use it heavily. For heavy users, a dedicated, "always
on" connection such as DSL or T1 is the better alternative.
Not only does such a connection provide access "on demand,"
it is also faster and easier to share with a large group of
users.
There are two types connection:
1) Dial-Up Connection
2) Non Dial-Up Connection
