First, briefBefore learning computer network in school when learning is the Network 7 layer model OSI, understand some basic computer network concepts and protocol communication format, but have not figured out the principle, including the relationship between the layers, applications, there are some common token ring network What is the thing, this OSI it and tcp/ What is the relationship between IP
Satellite communication has played an important role in the global communication field since its emergence in 1960s. With the emergence of the Internet tornado, the satellite Internet technology combined with the Internet has become a new hotspot in the development of satellite communication.

The use of domain Name System is to make it easy for network users to remember a large number of IP addresses, as long as by remembering a server's domain name as a character form, you can easily access the server's shared resources.

introduces the application layer protocol, the fifth part introduces the Next Generation Protocol, that is, the IPv6 protocol, and the sixth part introduces network security issues; the seventh part provides seven appendices. There are practice arrangements at the end of each chapter. The first part is the exercise, and the second part is the research activity.

ARP requests are constantly sent, occupying Internet resources, and thus users cannot access the Internet. A little similar to DDoS x×x, causing the server to fail to work normally.15. ARP spoofing XXX (man-in-the-middle XXX)

Haha! In September 18, I will take the National Computer Level 3 examination. I apply for network technology. Some students say this is simple, and now I have a lot of contact with my computer, it is best to know something about the TCP/IP protocol. I read some books today! Something about the TCP/IP protocol is found!

This article describes how to use domain Name Services (DNS) in Windows XP by configuring the TCP/IP protocol.
DNS is an Internet service that converts a domain name to an IP address. On the Internet, when you use a domain name during network operations, the DNS service is r
Network Protocol Reading Notes TCP/IP layering 1) Although TCP uses unreliable IP services, it provides a reliable transport layer service 2) UDP sends and accepts data packets for applications. A data packet is a unit of information transmitted from the sender to the receiver (a certain number of bytes specified by the sender), but different from TCP, UDP is unr

By default, php uses the http protocol to upload files of 2 MB, if you upload large files such as videos using the same http protocol as uploading small files, or developing an upload client in other languages based on the TCP/I

Provide the hardware address of the other host in the answer.The host of the corresponding destination hardware address in the proxy ARP answer must be able to send the IP datagram to the destination address specified in the ARP request.The approximate flow of the function is as follows:1.

first option field). MSS is the maximum data segment that TCP packets can transmit each time, and the length of TCP segment is larger than MSS, it is necessary to segment transmission. The TCP protocol usually negotiates the MSS values of both sides when establishing the connection, each of which has the MSS option to advertise its desired reception (MSS option only appears in the SYN segment, which is the first two times the TCP three handshake). MS
IGMP, 6 indicates TCP, and 17 indicates UDP. ip data decides to pass the data to ICMP based on the value in the Protocol domain, IGMP, TCP, and UDP. The other layers have similar Protocol domains. When the transport layer transmits data to the application layer, it determines the application layer software to be transmitted Based on the port number in the header
