For example, if a high-definition video conference session consumes all the high-priority delivery bandwidth on a port, a router might discard lower-priority packets (e.g., those associated with an SMTP mail transfer Too much wire left untwisted at termination -- or runs that are too long or bends that are too tight -- can introduce noise from external sources or from crosstalk among have a peek here
If the FCS checksum included in the frame doesnt match the recalculated number then an error has occurred during the transmission, the frame is discarded and the destination host requests it We’re a company of the brightest minds at the forefront of mobility.
