In the office or home internet connection that made is coming from what we called as dial up. Dial up is the way to connect to the internet that provided by ISP (Internet Services Provider). You can't bring it outside your office or home because dial up is static. But, it has absolutely fastest internet service.
In fact, there is another connection way instead dial-up, it is portable modem. But if you make some comparison about dial-up and portable modem, you will find huge differences between benefit and loss. I will make some points for you.
The benefit is portable modem perfectly fit for you that have high mobility. So you can bring it, and move it whenever you want. But, the packet cost that provided for modem is very expensive and if you wondering a fast connection I think you will never get it. Because portable modem is not for a fast connection. May be it is good if you just need connection to browsing or something, without download or upload.
Dial-up system has a very much of cables. So you can’t bring into the outside. But, this is the most effective internet connection I think. Because it has cheap cost and great speed for you that need that speed. Now we can use this dial-up internet starting at $9.95. So cheap and it will be the best connection for your home or office internet.
So, which one you choose ?
