Asymmetric Digital Subscriber Line (ADSL) advantages and disadvantages
(ADSL) connection is a type of Internet connection that is well-suited for the moderate gaming, the computer-aided design, streaming multimedia, and downloading the large files, It can be used for internet access at the same time as the voice calls, and it can be used for email and to receive the faxes.
DSL (Digital Subscriber Line) is a service which offers a faster Internet connection than a standard dial-up connection while ADSL (Asymmetric Digital Subscriber Line) is a type of DSL, It is a broadband connection technology that enables the computers to connect to each other over the Internet using the existing copper wired telephone networks.
DSL technology works by splitting the existing telephone line signal into two which are the voice and the data, ADSL uses most of the channel to transmit downstream to the user and only a small part to receive information from the user.
ADSL is a replacement for dial-up modems and ISDN, It appears to be always online, so, You do not wait to get connected to the Internet, the phone calls can be made at the same time as the ADSL link is being used.
Advantages of ADSL
Asymmetric Digital Subscriber Line (ADSL) offers high-speed connection, You can use the phone line while connected, It presents a fixed monthly cost, It has good value for the money, there is no extra wiring, ADSL uses the existing phone line, and it has lower pings in online games.
Asymmetric Digital Subscriber Line (ADSL) does not present more dropped connections, You can talk on the phone when you surf through the Internet because the voice and data work in separate bands which implies a separate channel.
Asymmetric Digital Subscriber Line (ADSL) use existing infrastructure (the basic telephone network), The cost and time it takes to keep the service available is less than if the operator had to undertake works to build new infrastructure, ADSL users have to access to the Internet, they do not have to establish this connection by dialing or signaling to the network, comparative ADSL compares with a switched network architecture.
Asymmetric Digital Subscriber Line (ADSL) presents connection speeds much higher than the one made by the dial-up Internet, It is a technology for high-speed Internet access, you are able to surf the web whilst allowing you to talk on the phone simultaneously.
ADSL connection can use a telephone and Internet simultaneously, You do not need to connect or reconnect, you are always online with ADSL, There are no call charges for using an ADSL connection like in the modem or ISDN connection, It offers you better internet functionality higher ADSL bandwidth compared with ISDN or the modem connection.
You can download the documents, the web pages and send email faster, You can view or send real-time audio and video files very quickly, ADSL can be very useful to the businesses to cut the call costs to the customers internationally, ADSL service is typically configured to internet usage as downloading is higher than uploading.
Asymmetric Digital Subscriber Line (ADSL) presents a broadband connection technology, ADSL uses the existing copper wires that installed for the telephone systems to deliver the high-rate digital data, They can provide the customers with high-speed data services even before switching to fiber-optics.
ADSL can offer high speeds around thirty to forty times faster than a dial-up connection, It uses a wide range of frequencies, ADSL connections offer the bandwidth needed for high-quality voice services, It is used for the web surfing, and the internet telephony and as a fax line at the same time.
Asymmetric of ADSL connection is because of its different capacity to download and upload, It offers more capacity for downloads from the internet to your computer than for uploads, The information you can send out in the particular time is much less than the amount of information you can download.
The ADSL connection is very useful because most users download more documents, the web pages and the emails that they send out, It makes use of your existing telephone line and splits the signal into the voice communications and high-speed data connection.
Disadvantages of ADSL
Asymmetric Digital Subscriber Line (ADSL) service is not available everywhere, It works better when closer to the ISP’s central office, It offers variable speeds depending upon the time of the day, It presents faster download than upload, The line testing takes a long time.
The home user contends at 50:1, you may share your 512 Kbps with 49 other people, giving you 10Kbps, ADSL is affected by the number of people are using your line in the certain area, The connection is faster to download (receive the data) than to send the information.
Every ADSL line is shared among 50 users so the ratio comes out to be 50:1 in case of the home users, whereas for the business users the ratio is 20:1, The users’ numbers can make your bandwidth fluctuate, ADSL connection does not offer any guarantee of the level service.
ADSL can travel reliably over the copper line only, so, if the telecommunications provider added the fiber between your organization and the local exchange, you will be unable to receive ADSL, When the distance from the telephone exchange is further, the signal strength is the weaker, Slower connection at peak times.
