Describe how a switch learns addresses?
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.
What does a switch store in its switching table?
The destination mac addressof a frame and the port it was received on.
Explain the store and forward method of switching give the advantage and disadvantage of this message switching technique what is packet switching?
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.
What is accurate about fast-forward switching?
The switch stores the first 64 bytes of the frame before forwarding.
What is layer 2 switching?
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.

1986 350 ford 6.9 desiel rear tank is not working?
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.
What is A switching mode in which a switch reads a frame's header and decides where to forward the data before it receives the entire packet?
Cut-through mode.
What switching method examines the destination MAC address as the frame is being received and then begins forwarding the frame prior to receiving the entire frame?
Cut through switching.
Why does a switch flood a frame?
Because it is a broadcast frame Because it is a multicast Frame Because the switch has no MAC address for it.
What is an updated and digital version of X25 that also relies on packet switching?
Frame relay.
What is difference between packet switching frame switching and cell switching?
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.
