What happens to runt frames received by a Cisco Ethernet switch? In an attempt to conserve bandwidth and not forward useless frames, Ethernet devices drop frames that are considered to be runt (less than 64 bytes) or jumbo (greater than 1500 bytes) frames. Ethernet frame The minimum Ethernet frame is 64 bytes. The maximum Ethernet frame is 1518 bytes. A network technician must know the minimum a..

reasons for physical layer protocols to use frame encoding techniques to distinguish data bits from control bits to identify where the frame starts and ends A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment. Which two factors m..

flow control Flow control allows for this by ensuring that data is not sent too fast for it to be received properly. encapsulation Encapsulation is the process of placing one message format into another message format. An example is how a packet is placed in its entirety into the data field as it is encapsulated into a frame. network protocols Network protocols are implemented in hardware, or so..
