Describe Network Functions And Equipment Flashcards
Each switch port has it own ___?
Collision Domain
What is stackwise?
Combines multiple switches into a single brain
ASIC?
(Application specific intergrated circuitry )
It is a chip inside of a L3 switch so it acts as a router
What is the difference between a router and a L3 switch?
L3 switch is hardware based and faster. L3 routes within the network.
A router is software based and is slowed. Routes forward data outside of the network.
What unique ID does a switch learn to remember which device to send frames to?
MAC Address
What are the primary functions of a switch?
- Receives frames and directs them to their destination
- Connects cables (copper or fiber optic)
- Learns MAC addresses and add them to a table.
What is a CAM table?
Content Accessible Memory.
It is the table the switch puts MAC addresses in that it learns.
What do routers do?
Routers are like the network wall. They keep devices from interfering with each other.
Primary functions of a router?
- Connects you to another network. Control broadcasts and forward data packets between networks.
- contains network chatter
- relies on IP-based routing table
- acts as a “gateway” between networks.
Does a router stop communication or allow communication to traverse the attached Network connection?
It does both
A computer would like to communicate with a server on the Internet. When it sends the communication
request out of its network card, which destination MAC address would you expect to see in the header?
The MAC Address of the Router
Which frequencies are used by the WAP to communicate in todays networks?
2.4GHz and 5GHz
What best describes a wireless channel?
A smaller “slice” of a larger group of radio frequency.
All standard based wireless communication adheres to the ___ standard ?
802.11
