In this article you will go through some interesting knowledge about DSL connection. You will come to know why it should be your first priority when choosing any internet connection. Some of the topics discussed in this article are enlisted below:
- What is DSL internet?
- History and evolution.
- It’s categories
- It’s working
- It’s merits and demerits
- 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 in order to prevent clash between internet connection and telephone calls.
It builds connections through telephone lines. The lines that are used to build telephone connection are used by it to build internet connection i.e. the connection is built on the existing telephones networks.
DSL Internet speed:
It does not offer much high speed. New technologies are being adopted to increase it’s speed. There are many methods by which you can measure the speed of your connection.
How fast is DSL:
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 used by some people.
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 it’s early days it got more fame in the eastern world.
Some of the categories of this connection are:
- Symmetric DSL (SDSL)
- Asymmetric DSL(ADSL)
- CONSUMER DSL(CDSL):
- High bit rate DSL(HDSL):
- RATE ADAPTIVE DSL (RADSL):
- UNIDIRECTIONAL DSL(UDSL):
Symmetric DSL (SDSL):
It allows equal amount of data to be flowed from both sides i.e. equal amount of data for both uploading and downloading. This one is not so much used by people. The reason for this will be cleared while discussing the next one.
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.
It is slower in speed than ADSL. It’s user have a benefit that they do not need to install any thing to split.
It’s some common names are:
- 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.
Its name defines it perfectly. It is the unidirectional form.
HOW DSL INTERNET WORKS?
Your telephone line services connects your home/company to the telephone company through twisted pair of wires which carry analog signals to transmit voice. It converts analog signals into electrical signals (in the form of amplitude and frequency). This analog transmission is used to transmit 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?
Broadband connection is that which provides greater capacity. No one type of internet connection can be referred to as broad band. All of them are types of broad band.
Digital Subscriber Line connection is basically a type of broadband connnection 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 sort of wires.
- Basically 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 same speed, no matter how many users increase.
- DSL connection is provided at a fixed location where as 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.
Some advantages of DSL are:
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 telephone.
With splitting lines, it provides facility of both telephone and internet, you do not need to have separate lines for internet. The data and voice can safely travel without interfering with each other.
Besides some merits, it has some demerits too. These are:
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 deicide to switch from one ISP to another.
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 switch on gain you are again in security threats, therefore users should have some sort of firewall installed on their pc.
WHY DSL IS A BETTER CHOICE AMONG ALL?
This connection proves to be a better choice in many cases. Some of them are described below
- If you need to host your own website then DSL would be your best choice.
- To set up your own server for gaming.
- For online chats
- Online shopping
- Online video streaming
Advancement in technology is the main reason for the commercial success of DSL. Different chips integrated on each other are being used to provide better services. Higher level of chips is benefitting it in the best way and it is becoming better from time to time.
People now don’t seem asking question ‘ What is DSL internet’ because it’s popularity in short span of time is speaking the words of success.
