transports files over tcp ip network

Computer network refers to the different geographic locations of multiple computers with independent functions and their external devices, through the communication lines connected together,Under the management and coordination of network operating system, network management software and network communication protocol,

I have written this article about the management of SCO TCP/IP. I hope it will be helpful to you, just like what was written at the beginning of this topic, this is the basis for hackers, and we still need to discuss it in the direction of network management! Haha!1 TCP/IP s

(segment). Session Layer: Manages the session process between hosts, including management during session creation, termination, and sessions. The presentation layer (presentation Layer): The presentation layer transforms the data transmitted by the network, so that the information transmitted between multiple hosts can understand each other, including data compression, encryption, format conversion and so on. Application layer (Application Layer): Th

What is the TCP.IP protocol? Generally speaking, TCP/IP protocol is the Technology foundation of Internet based on TCP/IP protocol (Transmission Protocol/Inter-network protocol). Full name Transmission Control protocol/internet Protocol. The Protocol of Transmission Control

I. TCP segment format: Shows the TCP segment format. Source Port Number and destination port numberThe source port number and destination port number, and the source IP address of the IP header and the destination IP address uniquely determine a

IP: network protocol IP is the most core protocol in the TCP/IP protocol cluster. It provides unreliable and connectionless datagram transmission services.Unreliable means that it cannot guarantee that the IP datagram can suc

the subnet mask, Gateway is the next hop address, iface is the sending interface, and the U mark in flags indicates that the entry is valid (some entries can be disabled ), the G flag indicates that the next hop address of this route entry is the address of a vro, And the entry without the G flag indicates that the destination network address is a network directly connected to the local interface and does

a host or a simple routing algorithm for it. essentially the difference is that the host never forwards the datagram from one interface to another, while the router forwards the datagram. The host that contains the router function should never forward datagrams unless it is set to that.In a general system, IP can accept datagrams from tcp,udp,icmp and IGMP (i.e. locally generated datagrams) and send them,

an application layer protocol, and its transmission is packaged into TCP protocol transmission. HTTP can be implemented with a socket. A socket is a programming API that implements the Transport layer protocol, either TCP or UDP. "Applicable Situation" If the two sides establish an HTTP connection, the server needs to wait until the client sends a request before the data can be passed back to the client, s

Digression: Originally wanted to follow the internet level from the bottom up review these agreements, but today really have to break the case, DHCP has to say!Host from one network to another network, then the structure of IP address will change, today's mainstream has the following several modification scenarios:(a) Change of address:The host changes its addres

recurring overhead, and it does not have the actual useful data, just to ensure the reliability of the link, so http/1.1 put forward a sustainable link implementation method. http/1.1 will use it to transmit a series of request/response messages repeatedly using only one TCP link, thus reducing the number of link builds and the frequent link overhead.Conclusion: HTTP is an application-layer protocol, and its transmission is packaged into

This protocol can provide connection-oriented, reliable, point-to-point communication.The UDP full name is the User Datagram Protocol, which can provide non-connected unreliable point-to-multipoint communication.With T
