The general term used when discussing the different types of connections between devices.
Convert 10010000 from binary to decimal
What is 144?
This Data Link Layer Sublayer is responsible for communicating with upper layer protocols.
What is Logical Link Control (LLC) sublayer?
This will happen if a host receives a frame with destination MAC address it does not recognize.
What is discard the frame?
This is used to prevent collisions when traffic is operating in Half Duplex Mode
What is CSMA/CA?
These three terms are used to measure quality of bandwidth in a network
What is Latency, Throughput, and Goodput
Convert 10011011 from binary to hexadecimal
What is 9B?
This WAN topology ensures highest fault tolerance.
What is Mesh?
This switching method views the first 64 bits of a frame for errors before forwarding the frame
What is Fragment-free switching?
What are accept the frame, de-encapsulate the frame, re-encapsulate the frame, and forward the frame?
This term is used to describe the loss of signal strength as distance increases.
What is attenuation?
Convert 4A from hexadecimal to binary
What is 01001010?
Which media communication mode does not require contention based or controlled based access control?
This buffer type puts all frames into a common memory buffer shared by all ports to avoid frames having to be placed into different queues before being forwarded
What is shared memory buffer?
This Frame Forwarding method has the highest latency due to receiving the entire frame before making forwarding decisions.
What is Store-and-forward Switching?
This term is used to describe when one wave modifies another wave.
