Exam 4: Ethernet Technology

The ____________________ coding method (originally developed for Fibre Channel) replaces 8-bit data values with 10-bit code words.

Originally, the ____ specification was used to standardize Ethernet communication over fiber.

The Ethernet ____________________ is the time required to transmit 512 bits.

The Preamble contains ____ bytes with the identical pattern 10101010.

The LSB (Least Significant Bit) for the SFD is set high (1).

What is the interframe gap?

For Ethernet, the MTU may range from ____.

When all the bits of a frame have been received, it is possible that the last bit received is not the last bit of the final byte in the frame.

____ are designed to prohibit retransmission of any frames for a short period of time when jabbering is detected, to prevent the network from being saturated with meaningless signals.

Describe the destination address of an Ethernet frame.

Diffused IR uses line-of-sight IR lasers and provides a faster data rate than diffused IR.
