We used to use ADSL broadband. ADSL: Asymmetric Digital Subscriber Line.
Broadband is used by connecting a phone line from your broadband carrier to your indoor modem (commonly known as a cat) and then using the cable to connect to other Internet-connected devices.
After years of development, ADSL has gone through three generations, from the original ADSL to the later improved ADSL2 and now ADSL2+, the download speed can now reach up to 24M. ADSL uses frequency division multiplexing to realize that the telephone signal, uplink and downlink signals do not affect each other.
Today, more use of fiber to the house (FTTH), after all, light transmission speed than electricity transmission speed, more efficient. FTTH works by pulling a fiber optic from the carrier to your home and connecting it to a light modem (commonly known as a light cat). Then use an Internet cable from the light cat to lead to the Internet.
Dial-up Internet generally refers to PPPoe dial-up, which is a way to access the Internet, both ADSL broadband dial-up (telephone line transmission) and fiber optic dial-up (fiber optic transmission). PPPoe refers to Point-to-Point Protocol Over Ethernet, which means that there are two identities of server and client in the point-to-point protocol PPPoe on the Internet. The operator receives and sends information to the client of ordinary users as a server, which is a one-to-many topology. In order to distinguish the identity and qualification of each client, each user needs to register an account and password in the operator, and then input the account and password on his computer using specific software to send it to the operator's server. If the account is legal, he can access the Internet normally. Of course, sometimes we will find that we can access the Internet without entering the account password in the computer. That is because the account password is preset on the cat, so we don't have to enter it manually.
