Domain name
A domain name is actually the name of a computer that is connected to the Internet. Its function is as important as writing people's names and addresses in a mail. The domain name structure is as follows: Host Name of the computer. organization name. Network Name. top-level domain name. Domain names are expressed in text, which is easier to remember than IP addresses expressed in numbers. All levels of networks that join the Internet follow the naming rules of DNS to name the computers in the network, and are responsible for converting the domain name to IP address during communication.
DNS Server
Domain Name System (DNS) is a directory service System that queries Domain names or IP addresses over the Internet. When receiving a request, it can translate the domain name of another host into an IP address or vice versa. Most domain name systems maintain a large database that describes the ing between domain names and IP addresses, and the database is regularly updated. A translation request is usually sent from another computer on the network. It requires an IP address for route selection.

Static IP addresses. Dynamic IP addresses refer to different addresses obtained by each connection, but static IP addresses
The status IP address is the same fixed address for each connection. Generally, the address obtained by dialing

TCP/IP Transmission Control Protocol/Internet Protocol
TCP/IP communication protocols mainly include the standards of network communication details on the Internet, as well as a set of network interconnection protocols and path selection algorithms. TCP is a transmission control protocol, which is equivalent to an item packing list to ensure that data is not lost during transmission. The IP address is an inter-network protocol, which is equivalent to the address and name of the recipient and ensures that the data arrives at the specified location.
TFTP Common File Transfer Protocol
TFTP is a simplified FTP protocol used by diskless computers to transmit information. It is very simple, so it can be solidified on the hard disk, and supports non-authentication operations. TFTP is a very insecure protocol.

UUCP is a cat-based file transfer protocol that has been used for a long time. Sometimes it is used to transmit Usenet news and E-mail over the Internet, especially on disconnected websites. Currently, few websites provide anonymous UUCP to access files. It is a File Transfer Protocol, which is used only by users who do not access the network and use the cat.

CGI public Gateway Interface
CGI (Common Gateway Interface) is a program that can produce the same results or the results change with user input. It can be written in an explanatory interface language or a compilation programming language. CGI specifies the interface protocol standard for the Web server to call other executable programs. The Web server calls the CGI program to implement interaction with the Web browser, that is, the CGI program receives and processes the information sent to the Web server by the Web browser, then, the response is sent back to the Web server and Web browser. CGI programs generally process form data on Web pages, query databases, and integrate with traditional application systems. Although CGI programs can be written in any programming language, CGI programs written in C language have the features of fast execution speed and high security.
CGI-based attack (CGI-based attack), which uses the vulnerabilities of public gateway interfaces to attack, usually through www sites.

Data-driven attack (data-driven attacks) relies on attacks that hide or encapsulate data, and the data is not noticed through the firewall.
DNS spoofing (Domain Name Server electronic spoofing) attackers use to damage the Domain Name Server, a method that can be achieved by spoofing the DNS's high-speed cache or internal attacks (generally, attackers pretend to be legitimate DNS server roles)
DoS (hey, it's not DOS, it's deniad of service, it's a massive Denial of service) when a user maliciously uses the network information server, it will refuse to provide services to legitimate users.

Firewall
Firework (firewall) is one or more systems that enhance security protection between the Internet and Intranetp (Intranet. The firewall can determine which internal services allow external access, which outsiders are permitted to access the internal services that are allowed, and which external services are accessible by internal personnel. To make the firewall effective, all information from and sent to the Internet must go through the firewall.
The firewall only allows authorization information to pass through, and the firewall itself cannot be infiltrated.

POP Internet email protocol standard
Is the abbreviation of Post Office Protocol, which is the internet email Protocol standard. We can send and receive emails through a host with the POP service function. The disadvantage of this protocol is that when you receive emails, all emails are cleared from the server and downloaded to your local disk. Of course, there are also some client programs that can leave the email on the server, or set to files larger than a certain size cannot be downloaded. As emails use multimedia formats, they will become larger and larger. We hope to be able to flexibly understand what files to download and when to download them. This requires the IMAP protocol. The current POP version is POP3.
Process
Proxy
Proxy server
The proxy service is used by the Web user to obtain the data back. Generally, when the WWW software is used to connect a remote terminal to obtain the data, the request signal must be sent one byte at a time. With the proxy settings, the signal requiring data will be sent to the Proxy Server first. When the Proxy Server receives a user request, it first goes to the cache to find the same information. If yes, the Proxy Server directly sends the data to the user. If no information is available in the cache, the Proxy Server uses the bandwidth available on the network to retrieve data from the remote platform, store the data in the cache, and send the data to the user. Even if the line is blocked, it is faster than directly capturing it by the user.
