While speed is the most noticeable difference once you buy the internet, the biggest difference while shopping for internet will be the price. The factor that influences price the most is the speed. Starting with dial up, it can several minutes to load your email or web pages. High speed internet is quite the opposite. Dial up is very slow as you may have noticed by now , but it can be made worse when others logon using the same service.
Dial up is also known for cutting out or the internet quitting intermittently, which is made worse by things like volume of users and weather. And with cable the speed can decrease if others are using the internet at the same as you.
Thus, they can substantially increase the amount of time it takes to load the desired page. Pop-up blockers help by preventing this process in the first place. Potential subscribers should keep in mind that there are some things that high speed dial-up just cannot do.
It cannot substantially increase speeds when downloading files, such as music or large attachments. It can also not speed up the downloading of many types of e-mail, or increase the speed of video streaming. Therefore, even with its advantages, there will still be some shortcomings in comparison to broadband. Ken Black. Mobile Newsletter banner close.

A PTT employee explains to a customer about subscribing to the new high-speed internet service at the post office in Hanoi, Vietnam. See more Internet connection pictures. High-speed Dial-up: Acceleration Servers " ". High-speed dial-up allows your machine to establish a connection with your ISP in a fraction of the time it takes with standard dial-up.
Your machine: Hello, my name is Sparky. Your machine: I am John's computer. ISP Server: John who? Your machine: John Smith. Your machine: He is one of your customers. ISP Server: Does he have an account number? Your machine: Yes. ISP Server: What is that number? OK, go ahead, You have access. Aren't you John Smith's machine. Your machine: Yes, his account number is ISP Server: Go ahead, Compression Filtering Caching.
High-speed Dial-up: File Compression The key element of high-speed dial-up Internet is file compression. For text files, including the HTML text of a Web page and the text in an e-mail message, the acceleration server compresses the text on the fly and sends it down your modem line. Typically, text will compress at least 50 percent using on-the-fly techniques. For image files, including GIF and JPG images on Web pages as well as many banner ads, the acceleration server reads the image from the Web site and recompresses it to reduce its size.
Typically, the image file size shrinks anywhere from 50 percent to 90 percent in the process. In many other files, including video files, Zip files and MP3 music files , compression has already taken place. For example, an MP3 file is already one-tenth the size of the original track on the CD.
It is not possible to compress the file any further in a quick way. In the case of secure Web pages, we already discussed why they cannot be compressed. The acceleration server will not touch these files -- it just passes them through as-is. Although the slower connection speed is a disadvantage for dialup users, there are also a few advantages to using this type of connection, which include lower monthly charges and a higher level of security.
In terms of security, because the connection is not "always on" and because you are assigned a different IP address each time, it is slightly more difficult to be attacked over the Internet, although nothing is ever fool proof and risks still do exist. The advantages of a broadband connection can sometimes outweigh some of the disadvantages.
The increased connection speed allows for ease in initial connection, duration of connection, no additional phone charges that may apply in dialing into an ISP, and variability of Internet use, such as an increase in allowable file viewing size.
However, if you do choose a broadband connection, you'll need to purchase a firewall-which we'll learn more about later-to keep your computer "invisible" to the outside world.
