NETWORKING WGU
# Term Definition
1 set of rules established for users protocol
to exchange information
2 network architecture used to topology
interconnect the networking
equipment
3 most common architectures for ring, bus, and star
LANs
4 Token Ring Topology a "token" (shown as a T) is placed in the data
channel and circulates around the ring. If a user
wants to transmit, the computer waits until it
has control of the token.
5 What is the IEEE 802.5? Token-Ring Network standard
6 Deterministic network each station connected to the network is
ensured access for transmission of its messages
at regular or fixed time intervals
7 What type of network is the deterministic
token ring?
8 Two disadvantages to token ring 1. if an error changes the token pattern, it can
topology cause the token to stop circulating 2. ring
networks rely on each system to relay the data
to the next user. A failed station can cause data
traffic to cease
9 Fix to disadvantages of token attach all the computers to a central Token Ring
ring topology hub
10 a device manages the passing of token ring hub
the token rather than relying on
individual computers to pass it,
11 What type of cable does bus coaxial cable (called ThinNet) is looped through
topology use? each networking device to facilitate data
transfer
,NETWORKING WGU
# Term Definition
12 System where computers share bus topology
the media (coaxial cable) for data
transmission
13 Who can see transmissions in All the computers
bus network?
14 One reason bus isn't used the use of a shared coaxial cable in a bus
anymore topology prevents data transmission from being
very bandwidth-efficient
15 What is the most common of star
today's LANs?
16 What is at the center of a star Switch or hub
network?
17 What is the difference between a Hub duplicates and broadcasts messages to all
switch and a hub? devices on network. Switch sends to specific
device.
18 What kind of cable does star twisted pair
network use?
19 What kind of device is a hub? Multiport repeater
20 physical input/output interfaces ports
to the networking hardware
21 topology where all networking mesh
devices are directly connected to
each other
22 developed by the International OSI (open systems interconnect) reference
Organization for Standardization model
in 1984 to enable different types
of networks to be linked together
23 What are the 7 OSI layers? Application - Presentation - Session - Transport -
Network - Data Link - Physical
, NETWORKING WGU
# Term Definition
24 OSI layer that provides the Physical
electrical and mechanical
connection to the network
25 OSI layer that handles error Data Link
recovery, flow control, and
sequencing
26 What is another word for flow synchronization
control?
27 Describes which terminals are sequencing
sending and which are receiving
28 Examples of physical layer UTP, fiber, and network interface cards
29 Which OSI layer is the media Data Link layer
access control layer and is where
Media Access Control (MAC)
addressing is defined?
30 What is the standard in the data Ethernet 802.3
link layer?
31 Layer that accepts outgoing network
messages and combines
messages or segments into
packets, adding a header that
includes routing information
32 What layer acts as the controller? Network
33 What are examples of the Protocols like Internet Protocol (IP) and
network layer? Internetwork Packet Exchange (IPX)
34 What layer is concerned with Transport
message integrity between
source and destination?
35 What layer Transport
segments/reassembles (the
packets) and handles flow
control?
