Every computer connected to the network must have a unique address to be accessed. There are usually ip addresses and domain name (dns) addresses. The domain name address (URL) will eventually be resolved into an ip address by the domain name resolution server.

The ip address of Ipv4 is a 32-bit binary number. The ip address of Ipv6 is 128 bits.

The domain name is the character address corresponding to the numeric ip address on the network, and the one-to-one correspondence is realized through dns domain name resolution.

E-mail is E-mail in the format of user name @ domain name. Domain name suffix.

SMTP (simple mail transfer protocol), which is the simple Mail transfer Protocol, belongs to the tcp/ip protocol family. The SMTP server complies with the SMTP protocol and is used to send or transfer users to send e-mail. The port number of Smtp is 25

ADSL access is a technology that provides broadband data services through ordinary telephone lines. This approach requires an ADSL Modem, or modem.

LAN access, also known as campus broadband access, is the use of Ethernet technology, the use of "optical cable + twisted pair" way to carry out comprehensive wiring to the community.

Optical fiber direct access refers to the complete use of optical fiber as the transmission medium between the office and the user.

Wireless access refers to the access technology that adopts wireless transmission partially or entirely from the switching node to the user terminal.

The information in the computer is digital information composed of 0 and 1, and the transmission on the telephone line is an analog electrical signal, so the conversion between the two signals uses modem (modem).

ISP:internet service providers, mainly China Telecom, China Unicom, China Mobile. ISP provides the user with an internet account, which is used to create a new PPPoE dial-up connection in the computer, and each time the user connects to the ISP network through this dial-up, the user will automatically be assigned a dynamic IP address.
