chapter 4 : the current ethernet specs Flashcards
When you are using only one wire pair with a digital signal either transmitting or receiving, what are you doing?P99
Half duplex
When converting to analog , the computer captures a series of samples in specified sizes which are called what?P99
Sampling size
If a host hears a digital signal it uses the—– – protocol to help prevent collisions and to permit retransmitting if a collision does occur.
CSMA?CD
A large 10baseT network will usually provide only —- – —- at most?P100
3Mbps to 4Mbps
Does a Full duplex Ethernet uses to pairs of wires at the same time instead of one measly wire pair like a half duplex?P100 T/F
True
What uses a point to point connection between a transmitter of the sending device and the receiving device?P100
Full duplex
Full duplex ethernet can be used in many situation , what are some of the situation?P100
Connection from a switch to a host,connecting from a switch to switch, connecting from a host to a host using a crossover cable.
You can run a full duplex with just about any device except a hub?P100 T/F
True
When a full duplex ethernert port is powered on , it first connects to the remote end and then negotiates with the other end of the fast ethernet link, and what is this called?P100
Auto detect mechanism
ARE there collisions in a full duplex?P101 Y/N
yes
A dedicated switch port is not required for each full duplex host?P101 T/F
False
Ethernet at the data link layer is responsible for ethernet addressing commonly known as?P101
Hardware addressing or MAC addressing.
What shares a collision domain and provides a lower effective throughput than a full duplex ethernet?P101
Half duplex ethernet
How many bits equal a bite?P103
8
What binary value does 224 have?P103
11100000
