We used to use ADSL broadband online. ADSL: Asymmetrical digital subscriber line.
Broadband is used by taking a phone cable from a broadband operator to an indoor modem (called the cat) and then connecting it to other Internet devices.
After years of development, ADSL has gone through three generations, from the initial ADSL to the later improved ADSL 2 to the current ADSL 2 +, the downward speed can now reach up to 24M. ADSL adopts frequency division multiplexing to realize the telephone signal, uplink and downstream signals without affecting each other.
Today, more use is fiber-to-home FTTH (fiber to the house), which transmits faster and more efficiently than electricity. FTTH works by pulling a fiber from the operator to the home to a light modem (commonly known as the light cat). Then use a network cable from the light cat to lead out of the Internet.
Dial-up Internet access generally refers to PPPoe dial, is a way of Internet access, both ADSL broadband dial (telephone line transmission) and optical fiber dial (optical fiber transmission). PPPoe refers to Point-to-Point Protocol Over Ethernet, which means that there are server and client identities in the online point-to-point protocol PPPoe. As a client that receives and sends information to ordinary users, the operator is a one-to-many topological structure. In order to distinguish the identity and qualification of each client, each user needs to register an account password with the operator, and then send the account password to the server on the computer. If the account is legal, they can access the Internet normally. Of course, sometimes we will also find that we can surf the Internet without using the software to enter the account and password in the computer, that is because the account and password is preset on the cat, so we can not manually enter.
