|
The physical star topology has a switch at the center.
|
|
|
What name is given to the access method used by wireless device?
|
CSMA/CA is the access method used by wireless devices.
|
|
|
what does a logical topology depend on?
|
A logical topology depends on how the signals move.
|
|
|
CSMA/CD applies to which of the following?
|
CSMA/CD only applies to wired half-duplex networks.
|
|
|
Which 10 Gbps Ethernet standard uses single-mode fiber-optic cabling, supports a distance of more then 2km, and is not SONET-compatible?
|
10GBaseER is single-mode fiber over and extended range of up to 40 km.
|
|
|
What network topology is most fault tolerant?

|
|
|
When full duplex is enabled on a link, which of the following is disabled?
|
Full-duplex Ethernet, where both ends of the link can simultaneously send and receive, had negated the need for CSMA/CD, and algorithm is actually disabled on a full-duplex link.
|
|
|
What term refers to a situation where two half-duplex nodes send messages at the same time?
|
collisions were handled with CSMA/CD on wired Ethernet networks, and are handled with CSMA/CA on wireless networks.
|
|
|
Which of the following is a Gigabit standard that uses multimode fiber-optic cabling?
|
100Base SX is the Gigabit standard that uses multimode fiber-optic cabling, which is the type of fiber cabling used to cover short distances.
|
|
|
What does the base in baseband refer to?
|
