6.3 Flashcards
Allows the user to optimize avaible IP addresses by specifiying a different subnet mask for an IP netowrk, and therefore create subnets of different sizes.
Variable-Length Subnet Masking (VLSM)
What tasks are switches able to perform?
- Used to eliminate the number of collisions on an Ethernet network.
- Switching at Layer 2 breaks up collision domains
- Direct raffic based on the source and destination MAC addresses attached to individual frames.
Enables the switch to forward fames based on physical address.
Content Addressable Memory (CAM)
A copy of the CAM in human-readabl format and wis what an administrator sees when looking at a switch configuration.
MAC Address Table (MAT)
Interconnecting multiple switches on a LAN can sometimes create what is called a ________._
Bridge Loop
Enables switches to detect and fix bridge loops by blocking redundant loops.
Spanning Tree Protocol (STP)
What is world’s most popular LAN standard?
Ethernet standard 802.3
What is the speed, alternative names, standard and cable types of regular Ethernet?
- Speed 10Mbps
- Alternative 10Base-2, 10Base-5, 10Base-T
- Standard IEEE 802.3
- Cable Type Coaxial, Coaxial, Copper
A network that risks collisions between the frames they send because they are on a shared Ethernet channel;Uses CSMA/CD.
Half-duplex Ethernet
Imposes half-duplex logic on each device, which limits transmission to one station at a time, providing the ability for devices to listen to the network prior to transmitting.
Carrier Sense Multiple Access with Collision Detecting (CSMA/CD)
A mode of operation allowing simultaneous communication between a pair of stations.
Full-duplex Ethernet
TCP/IP uses what type of Ethernet Framing?
DIX Version II
NOVELL uses what type of Ethernet Framing?
IEEE 802.3
Directs traffic based on the source and destination logical addressing (most commonly IP) attached to packets.
Router
The router that connects the LAN to the WAN.
Default Gateway
