TCP is a reliable stream delivery service that ensures that all bytes received are in the same order as the bytes sent. Because the transmission of data packets by many networks is unreliable, TCP uses a technique called positive acknowledgement with re-transmission to achieve this goal. When IP...
Transmission Control Protocol (TCP) is a standard protocol on the internet that ensures the reliable transmission of data between devices on a network. It defines how to establish and maintain a network conversation by which applications can exchange data. One of the main communication protocols of ...
TCP FIN packet is required to close a connection. During normal circumstances both sides are sending and receiving data simultaneously.
A teardrop attack is a type of IP fragmentation attack that targets the TCP/IP reassembly mechanism, occurring after a three-way handshake has been completed and data is being transmitted. It involves an attacker deliberately sending data packets with defective segment offset fields, preventing the...
"Datagram" is a segment of data sent over a packet-switched network. A datagram contains enough information to be routed from its source to its destination. By this definition, an IP packet is one example of a datagram. Essentially, datagram is an alternative term for "packet." What is ne...
As another example, theTransmission Control Protocol (TCP)ensures that the transportation of packets of data across networks goes smoothly. Therefore, TCP is considered a transport layer (layer 4) protocol. *A packet is a small segment of data; all data sent over a network is divided into pac...
When referring to the data structures of a packet, what is the proper term to refer to a single unit of TCP data at the transport layer?当提及一个数据包结构时,以下哪项可以表示一个TCP包在传输层的单个数据单元?()A.TCP segment.TCP段B.TCP packet.TCP包C.TCP frame.TCP帧D.TCP datagram.TCP...
Ping can also be used to test the IPv4 loopback address (127.0.0.1) and verify that the local TCP/IP stack is functioning properly on the host machine. Since ping is a simple, straightforward program, it is easy to incorporate into scripts for automated testing and diagnostics. If the ping...
TCP/IP is a functional model designed to solve specific communication problems, and which is based on specific, standard protocols. OSI is a generic, protocol-independent model intended to describe all forms of network communication. In TCP/IP, most applications use all the layers, while in OSI...
