Wireshark screenshot of an Ethernet pause frame. Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to avoid packet loss in the presence of network congestion. The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x ...

Per the end-to-end principle, the Internet Protocol leaves responsibility for packet recovery through the retransmission of dropped packets to the endpoints - the computers sending and receiving the data. They are in the best position to decide whether retransmission is necessary because the application sending the data should know whether a ...
Frequent use of a serial port is for a direct computer-to-computer connection. This requires an adapter called a null modem, which isn't actually a modem in the traditional sense, but rather a connector plug that simply crosses the complementary pins on two serial ports so the two sides can communicate. A null modem typically connects the DTR ...
An Ethernet adapter card for the IBM PC was released in 1982, and, by 1985, 3Com had sold 100,000. [16] In the 1980s, IBM's own PC Network product competed with Ethernet for the PC, and through the 1980s, LAN hardware, in general, was not common on PCs. However, in the mid to late 1980s, PC networking did become popular in offices and schools ...
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system , a port is a logical construct that identifies a specific process or a type of network service .
Actually any TCP connection can timeout and disconnect, and UDP packets can get discarded. Since the continuation of a TCP download stream depends on acknowledgement (ACK) packets in the upload stream, a bufferbloat problem in the upload can cause failure of other non-related download applications, because the client ACK packets do not timely ...
