topology Flashcards
is used to denote the arrangement of the
network devices in a computer network.
Network Topology`
A is designed with each node connected directly to a central device called as a network switch.
Star Topology
Advantages of Star Topology
Easy to install and wire.
No disruptions to the network when
connecting or removing devices.
Easy to detect faults and to remove parts.
Disadvantages of Star Topology
Requires more cable length than a bus topology.
all devices in the network are connected via a cable that loops in a logical
ring or circle.
RING Topology
ADVANTAGES OF RING TOPO
the signal
degeneration is low since each workstation participating in the
network is responsible for regenerating the weak signal.
Disadvantages of RING Topology
the failure of one device
in the network can cause the failure entire network.
A consists of a main run of cable with a terminator at each end.
bus topology
Advantages of Bus Topology
Requires less cable length than a star topology.
Disadvantages of BUS Topology
- Entire network shuts down if there is a break in the main cable.
A is a network setup where each computer and network device is interconnected
with one another.
mesh topology
each device on the network is connected together
FULL MESH TOPOLOGY
advantage in full-mesh topology
if any connection between two devices
failed, there is always an alternate path
Disadvantages of full-mesh topology
The cabling costs of full-mesh topology-based network can be very
high.
some of the devices are connected to many devices together, but other devices are connected only to one or two devices.
-PARTIAL MESH TOPOLOGY
is used in bigger networks compared with Ad hoc
wireless topology. Is normally used to extend a
wired LAN to connect wireless capable devices.
Infrastructure Wireless Topology
devices are connected
without using any additional network infrastructure devices like
a wireless Access Point (AP).
Ad hoc Wireless Topology
wireless devices are meshed
together for redundancy. If any failure in a wireless mesh
topology device, other redundant paths are available.
Wireless Mesh Topology
Network adapter is a device that enables a computer to talk with
other computer/network.
NETWORK INTERFACE CARD
is a device that splits a network connection into multiple
computers
HUB
is a telecommunication device grouped as one of computer
network components. is like a Hub but built in with advanced
features
Switch
is a device that can be configured and properly managed to offer a more tailored
experience to those who will be utilizing the box
MANAGED SWITCH
are plug and play devices without the need of a complex setup
UNMANAGED SWITCHES
more resembles like TV installation cable. It is more expensive
than twisted-pair cable but provide high data transmission speed.
COAXIAL CABLE
It is a high-speed cable which transmits data using light beams through a glass
bound fibers.
FIBER-OPTIC CABLE
used to connect a LAN with an internet connection
router
is a wireless network device that acts as a portal
for devices to connect to a local area network.
ACCESS POINT
is short for “Modulator-Demodulator.” It is a hardware component
that allows a computer or another device, such as a router or switch,
to connect to the Internet
MODEM
