Ist nicht gerade wenig... wäre aber wirklich sehr froh wenn mir einer helfen könnte. Begriffe wie "switch" müssen nicht übersetzt werden. Auch bitte keine 1 zu 1 Übersetzung, sondern Sinngemäß.
Ich muss den Inhalt nämlich verstehen und Englisch ist für mich der Horror schlechthin.

Ethernet is a shared media, baseband technology, which means only one node can transmit data at a time. Increasing the number of nodes on a single segment increases demand on the available bandwidth. This is turn increases the probability of collisions. A solution to the problem ist to break a large network segment into parts and separate it into isolated collsion domains. Bridges and switches are used to segment the network into multiple collision domains.
Switches provide a virtual connection directly between the source and destination nodes. Each port creates its own collision domain. A switch dynamically builds and maintains a Content-Addressable Memory (CAM) table, holding all of the necessary MAC information for each port.
Two devices connected through a switch port become a small collision domain. These small physical segments are called micro segments. Micro segments connected using twisted pair cabling are capable of full-duplex communications. In full duplex mode, when separate wires are used for transmitting and receiving between two hosts, there is no contention for the media. Thus, a collision domain no longer exists.
How a frame is switched affects latency and reliability. A switch can start to transfer the frame as soon results in the lowest latency through the destination MAC address is received. Switching at this point is called cut-through switching and checking. At the other extreme, the switch can receive the entire frame before sending it out the destination port. This is called store-and-forward switching. Fragment-free switching reads and checks the first sixty-four bytes of the frame before forwarding it to the destination port.
Switched networks are often designed with redundant paths to provide for reliability and fault tolerance. Switches use the Spanning-Tree Protocol (STP) to identify and shut down redundant paths through the network. The result is a logical hierarchical path through the network with no loops.
Using Layer 2 devices to break up a LAN into multiple collision domains increases available bandwidth for every host. But Layer 2 devices forward broadcasts, such as ARP requests. A Layer 3 device is required to control broadcasts and define broadcast domains.
