The Transport layer
exchanging of data between interconnected devices
USB (Universal Serial Bus) itself is a data transfer bus that is only responsible for exchanging data and not doing anything else with it. It is just an interface or infrastructure. However, it connects to input devices, output devices, and bidirectional devices.
backbone
Physical layer devices would be a hub or a repeater to connect multiple Ethernet segments together.
The edge transport role in networking refers to devices or services located at the edge of a network, where data enters or exits. These devices are responsible for transporting data between different networks or network segments securely and efficiently. Edge transport plays a crucial role in managing network traffic, applying security protocols, and ensuring data delivery to its intended destination.
The term is "data communication" or "network communication," which is the process of exchanging data between two or more devices. This can involve various methods such as wired or wireless transmissions, protocols, and communication standards.
They are designed to interconnect local network segments.
On a standard Ethernet network, between any two devices that communicate (such as computers), you can't have more than 4 repeaters (this includes hubs). "5-4-3" refers to a maximum of 5 segments; 4 repeaters; 3 segments with hosts on them.
Major industry product segments include aircraft engine instruments; nuclear radiation detection and monitoring instruments; commercial, geophysical, meteorological,
A guideline for 10-Mbps Ethernet networks stating that between two communicating nodes, the network cannot contain more than five network segments connected by four repeating devices, and no more than three of the segments may be populated.
