C172 Exam 1 Questions with 100% Verified
Correct Answers
LAN
Local area network. Network of users that share computer resources in a limited area.
Protocol
Set of rules established for users to exchange information
Topology
Architecture of a network
Token Ring Topology
A network topology configured in a logical ring that complements the token passing protocol
Token Passing
A technique where an electrical token circulates around a network—control of the token
enables the user to gain access to the network
Deterministic
Access to the network is provided at fixed time intervals
Bus Topology
The computers share the media (coaxial cable) for data transmission
ThinNet
A type of coaxial cable used to connect LANs configured with a bus topology
Star Topology
, The most common networking topology in today's LANs where all networking devices
connect to a central switch or hub
Hub
Broadcasts the data it receives to all devices connected to its ports. A hub is a Multiport
Repeater.
Switch
Forwards a frame it receives directly out the port associated with its destination address
Ports
The physical input/output interfaces to the networking hardware
Mesh Topology
All networking devices are directly connected to each other
OSI
Open system interconnect
OSI Model
The seven layers describing network functions
1. Physical
2. Data Link
3. Network
4. Transport
5. Session
