INTRODUCTION:

In this article, you will go through some interesting knowledge about DSL connection. You will come to know why it should be your priority when choosing any internet connection. You will know what DSL internet is. Some of the topics discussed in this article are enlisted below:

• History and evolution.
• It’s categories
• It’s working
• It’s merits and demerits
• The difference between internet connections.

What is DSL internet?    

    It stands for Digital Subscriber Line. It provides online services through the same network as that of telephone lines. Filters are added to prevent the clash between the internet connection and phone calls.

It builds connections through phone lines. The lines that are used to make telephone connection are used by it to build internet connection i.e. the connection is made on the existing phones networks.

What is DSL Internet speed?

It does not offer much high speed. New technologies are being adopted to increase its speed. There are many methods by which you can measure the speed of your connection.

 What is DSL internet price? How fast is it?

It’s speed is between 128 Kbps– 3000 Kbps. The technology got fame almost 20 years ago. Now it is not much used by people because of slow speed. It is much cheaper than other types. Because of low rates, it is still utilised by some people.

HISTORY:    

It was introduced in 1990, from then it got fame very quickly. With the invent of new technologies it got better from time to time. In its early days, it got more fame in the eastern world.

CATEGORIES:

Some of the classes of this connection are:

1. Symmetric DSL
2. Asymmetric DSL
3. CONSUMER DSL
4. DSL-LITE
5. High bit rate DSL
6. RATE ADAPTIVE DSL
7. UNIDIRECTIONAL DSL

• Symmetric DSL (SDSL):

It allows an equal amount of data to be flowed from both sides i.e. same amount of data for both uploading and downloading. People do not so much use this one. The reason for this will be cleared while discussing the next one.

• ASYMMETRIC DSL(ADSL):

This one is loved by online users because it provides greater area for downloading data. This is the most common because people are interested in downloading than in uploading data.

• CONSUMER DSL(CDSL):

It is slower in speed than ADSL. It’s user have a benefit that they do not need to install anything to split.

• DSL-LITE:

It’s some common names are:

• G-LITE
• Universal ADSL
• Splitter-less ADSL

In the last type, there is no need of splitter at the user’s end but a need may arise of splitting the lines for user remotely at the telephone company side.

• High bit rate DSL(HDSL):

It is symmetrical i.e. an equal bandwidth is available in both directions. It can carry 1.5Mbps – 2 Mbps of data approximately.

• RATE ADAPTIVE DSL (RADSL):

In this type, the signal transmission rate can be determined through software. Delivery rate is also determined with the help of some software.

• UNIDIRECTIONAL DSL(UDSL):

Its name defines it perfectly. It is the unidirectional form.

HOW DOES DSL INTERNET WORK?

Your telephone line services connect your home/company to the phone company through twisted pair of wires which carry analogue signals to transmit voice. It converts analogue signals into electrical signals (in the form of amplitude and frequency). This analogue transmission is used to send information to both ends. You just need to have a modem with your PC to convert that information into digital information.

WHAT IS THE DIFFERENCE BETWEEN DSL AND BROADBAND INTERNET?

Dsl vs. Broadband:

A broadband connection is that which provides greater capacity. No one type of internet connection can be referred to as broadband. All of them are types of broadband.

Digital Subscriber Line connection is a kind of broadband connection in which there is no need of making separate areas for connection as long as you have a telephone connection in your home.

IS DSL INTERNET THE SAME AS WIRELESS?

They are quite different from each other. Following points show their difference:

• It provides services through telephones line, whereas wireless connection is one which provides its services through modem linked to an ISP. Wireless connection is independent of any wires.

• The wireless network comes from a router; this can be a DSL modem or a wireless modem.
• A wireless connection slows down with the increase in no of users, whereas in DSL you get the same speed, no matter how many users grow.
• Its connection is provided at a fixed location whereas wireless connections are spread over towers.

WHICH ONE TO CHOOSE? DSL OR WIRELESS?

When choosing for a travelling purpose, you will go for wireless, while for use at home you will choose fast DSL connection. Thus both of them have equal significance.

ADVANTAGES:

Some benefits  are:

• SPEED:

It provides good speed. However exact speed may vary depending on the service plan.

• 24 HOURS AVAILABILITY:

It is available 24 hours a day. You do not need to contact your  ISP each time to configure settings. With the help of this connection, you can be online even when you are talking on the telephone.

• DUAL ACCESS:

  

With splitting lines, it provides the facility of both phone and internet; you do not need to have separate lines for the internet. The data and voice can safely travel without interfering with each other.

DISADVANTAGES:

Besides some merits, it has some demerits too. These are:

• COST:

You should have a modem; this means you will have to spend some extra amount and this can be quite irritating for you when you decide to switch from one ISP to another.

• SECURITY:

While using this connection, You can have security threats too. As it provides services 24 hours, this means that your PC will be online for a long time, even if you switch off your PC and then when switching it on the again you are in security threats. Therefore users should have some firewall installed on their PC.

WHY IS DSL A BETTER CHOICE AMONG ALL?

This connection proves to be a better option in many cases. Some of them are described below

• If you need to host your website, then it would be your best choice.
• To set up your server for gaming.
• For online chats
• Online shopping
• Online video streaming

FINAL WORDS:

Advancement in technology is the main reason for the commercial success of DSL. Different chips integrated with each other are being used to provide better services. A Higher level of chips is benefiting it in the best way, and it is becoming better from time to time.

People now don’t seem to ask question  ‘ What is DSL internet’ because it’s popularity in short span of time is speaking the words of success. You can read more at: What is networking?
