There are two variants of Internet access. They are dial up and not switched lines. What is dial up access? To connect this way clients call operator from their home phone with further connection. Not switched access is a permanent connection with provider by the dedicated line, phone line with xDSL technology, by TV cable or by the radio channel.
One of the most important questions for the clients is - what is dial up access advantage? The main reason for dial up service usage is its price. There are some propositions for free dialup accounts. Therefore it is proper solution just for private persons. It should not be used when long time of Internet connection is required, because you should pay for the phone line usage as well.
Nowadays usage of dedicated lines becomes more popular. In the last years cost of connection via the dedicated line was decreased some times. This fact is explained by the decreasing of hardware cost and providers' competition growth. In these conditions question "what is dial up access" becomes less popular.
At the same time technologies of the dedicated lines building are not very different. The most part of the lines are rented at the higher level provider. This is reselling business that is very popular in Internet nowadays. Therefore client will feel the difference when he tries the services from some providers. Quality of Internet service depends on the capacity ability and quality of the external channel. The last link in the chain of hardware setup is the cable to the client's PC. The qualification level of the provider's support level is also the significant component. Modern providers use fibre cable for the channels maintenance. This is preferred solution comparing to the satellite communications.
One more reason to forget about what is dial up access is the cable Internet service. This is one of the most popular alternatives to the dial up access available for private persons. Cable TV operators could provide Internet service. This type of connection allows avoiding dependence from the phone lines operators tariffs. This fact allows establishing lower level of the tariffs. At the same time client is able to watch the digital TV programs as before.
Cable Internet is an optimal solution by its price and quality. There is no need build the dedicated lines because an access is provided on the base of TV cable. Cable Internet technology does not require maintenance of the response hardware part at the provider's area. These factors are making client connection cheaper.
This service could provide many advantages for the corporations as well. High capacity of the systems and opportunity for clients to communicate without support of external servers allows implementing such abilities as simultaneous work at the same documents and access to the corporative databases. There is one more step in this technology. This is VPN service that creates the protected dedicated line for the offices connection. So major corporative networks will be available very soon.
