3.1-3.3 Flashcards
A transceiver is responsible for
converts digital data from pc to digital signal to be sent on the network and vice versa
A GBIC (gigabit interface converter)
is a large transceiver that fits in a port slot and is used for Gigabit media, including copper and fiber optic.
SFP (small form-factor pluggable)
is similar to a GBIC, but is a smaller size. An SFP is sometimes called a mini- GBIC.
SFP+
is a newer version of the SFP. SFP+ supports data rates as high as 10 Gbit/s, 8 Gbit/s Fiber Channel,
QSFP (quad, or 4-channel, small form-factor pluggable) is a
compact hot-pluggable transceiver that is also used for data communication applications.
A hub is the central connecting point of
a physical star, logical bus topology. -A hub is a Layer 1 Device
Routers can be used to connect
subnets within a single LAN, or they can be used as gateways to connect multiple LANs together.
Firewall rules control
the type of traffic allowed into a network and the type of traffic allowed out of a network.
A firewall can be either
hardware or software installed onto operating systems.
Multilayer switch combines the functionality
of a switch and a router.
The type of signal the transceiver sends depends
on the type of network. -A fiber optic NIC sends light signals -A wired NIC sends electronic signals on a wire -Wireless NIC sends radio signals.
Bi-directional transceiver, or BiDi, can
transmit and receive data through a single optical fiber.
Functions of a MultiLayer Switch
Connects devices that are on the same subnet or virtual LAN at lightning speeds and has IP routing intelligence so it doubles as a router
