What
is
an
ISP?
|
|
ISP
|
| Short
for
Internet
Service
Provider,
a
company
that
provides
access
to
the
Internet.
For
a
monthly
fee,
the
service
provider
gives
you
a
software
package,
username,
password
and
access
phone
number.
Equipped
with
a
modem,
you
can
then
log
on
to
the
Internet
and
browse
the
World
Wide
Web
and
USENET,
and
send
and
receive
e-mail.
In
addition
to
serving
individuals,
ISPs
also
serve
large
companies,
providing
a
direct
connection
from
the
company's
networks
to
the
Internet.
ISPs
themselves
are
connected
to
one
another
through
Network
Access
Points
(NAPs).
ISPs
are
also
called
IAPs
(Internet
Access
Providers).

Internet
|
| A
global
network
connecting
millions
of
computers.
More
than
100
countries
are
linked
into
exchanges
of
data,
news
and
opinions.
Unlike
online
services,
which
are
centrally
controlled,
the
Internet
is
decentralized
by
design.
Each
Internet
computer,
called
a
host,
is
independent.
Its
operators
can
choose
which
Internet
services
to
use
and
which
local
services
to
make
available
to
the
global
Internet
community.
Remarkably,
this
anarchy
by
design
works
exceedingly
well.
There
are
a
variety
of
ways
to
access
the
Internet.
Most
online
services,
such
as
America
Online,
offer
access
to
some
Internet
services.
It
is
also
possible
to
gain
access
through
a
commercial
Internet
Service
Provider
(ISP).
The
Internet
is
not
synonymous
with
World
Wide
Web.

|
|
|
World
Wide
Web
|
| A
system
of
Internet
servers
that
support
specially
formatted
documents.
The
documents
are
formatted
in
a
markup
language
called
HTML
(HyperText
Markup
Language)
that
supports
links
to
other
documents,
as
well
as
graphics,
audio,
and
video
files.
This
means
you
can
jump
from
one
document
to
another
simply
by
clicking
on
hot
spots.
Not
all
Internet
servers
are
part
of
the
World
Wide
Web.
There
are
several
applications
called
Web
browsers
that
make
it
easy
to
access
the
World
Wide
Web;
Two
of
the
most
popular
being
Netscape
Navigator
and
Microsoft's
Internet
Explorer.
World
Wide
Web
is
not
synonymous
with
the
Internet.
