frame check sequence.
Network + Guide To Networks Review Question Chapter 6 #11
c. frame check sequence.
A switch examines the frame for the MAC address information and adds it to its internal switching table as each frame passes through the switch.
The destination mac addressof a frame and the port it was received on.
In this type of switching, the entire frame is read and stored in memory before being sent to the destination device. The switch checks the integrity of the bits in the frame by recalculating the cyclic redundancy check (CRC) value. If the calculated CRC value is the same as the CRC field value in the frame, the switch forwards the frame out the destination port. The switch does not forward frames if the CRC values do not match. The CRC value is located within the frame check sequence (FCS) field of an Ethernet frame. Although this method keeps damaged frames from being switched to other network segments, it introduces the highest amount of latency. Due to the latency incurred by the store and forward method, it is typically only used in environments where errors are likely to occur, such as environments that have a high probability of EMI.
The switch stores the first 64 bytes of the frame before forwarding.
This refers to switching at layer 2 of the OSI reference model, for example, Ethernet. A switch looks at the MAC address of each Ethernet frame ("packet", you might say, but at this level the correct name is "frame"), and if it knows that this MAC address is connected at a certain port, the switch will send the information out ONLY through that port.This refers to switching at layer 2 of the OSI reference model, for example, Ethernet.

Depending on if the switching unit is working on the frame rail on the driver's side just at the rear of the cab. It might not be switching to the rear if that switch is not working, also check the switch on the dash.
Cut-through mode.
Cut through switching.
Because it is a broadcast frame Because it is a multicast Frame Because the switch has no MAC address for it.
Frame relay.
Packet Switching refers to the transfering of the packet from 1 node to the other. Where as Cell Switching ,means the switching of a cell from 1 network to the other. Pls note that Packet and Cells are 2 different forms. Packet itself has header and pay load and but Packets are variable in size unlike cells which are fix. When packets are switched, the Packet Switch is used and that Switch looks for the next hop in its routing or forwarding table but when a cell is switched, ATM switches are used and the cells actually carry the data and the header and travels from 1 ATM switch to the other. The ATM switches donot use the complex method as Packet Switches use.
