Dialup UK Article - Main Characteristics Of Internet
The Internet is a worldwide network of computers. It is an
interconnection of large and small networks around the globe.
The internet is one of most powerful communications tool.
It empowers its users with instantaneous access to a huge
pool of data, tools and the information to accomplish many
different tasks. The Internet is used for business and pleasure
alike. Here, we discuss the main defining characteristics
of the internet.
Internet is network of networks. There are several layers
and modes of communications among the layers. Hence, some
standards have been raised to allow proper level of communication
across networks. However, these standards do not restrict
the access of information to a particular location. The information
flows freely across the networks in the standardized manner.
Another remarkable feature of the Internet is Flexibility
on the transfer of the data. Internet is basically a network
that carries information in digital form in majority of the
cases instead of voice information in analog form. There are
many instances where these two different forms of data transfer
starts to overlap. Dialup Internet connection is one example
where regular phone lines are technically carrying data over
a voice line. With advance of internet technology, digital
phone lines are also developed in some regions.
A notable difference from the phone connection is that the
path of the data transfer is not fixed from start. A telephone
call is circuit establishes a dedicated path to transmit our
entire conversation. Internet connections are not fixed from
point to point for the duration of the transmission. Data
sent over the internet is in form of packets. It transmits
a small part of the data, verifies it is correct and then
sends more information toward the destination. Internet does
not require all of the information to be delivered through
the same path at same time…
The architecture of the internet is also different from the
other types of communication. The internet follows a client
sever architecture. A server is a computer loaded with a software
package that provides requested information to clients. A
client is a software program that contacts to a server and
requests information. There are different kinds of servers
softwares. A single hardware server computer could have several
different types of server software packages running on it.
For example, you could have a web server, e-mail server or
a chat server running on a single hardware computer server.
Client sends its request to the server with its own address
so that the information will be returned to the correct location.
However, the client requesting services must match the type
of service that it is connecting to. The client software has
to match up to an exact kind of server software and each server
requires a specific kind of client software. For example,
If you were looking for a web page, you would use a web client
to access a web server. If you want to get your e-mail, you
would use an e-mail server.
These features make Internet a unique and highly efficient
network of networks.
