Network Plus N10-008 Jason Dion Study guide
questions with answers
Hub - CORRECT ANSWERS ✔✔A device that uses its ports to connect devices
(computers, printers, etc.) together
Wireless Access Point WAP - CORRECT ANSWERS ✔✔gives wireless devices a
sending and receiving connection point to the network
Switch - CORRECT ANSWERS ✔✔Connects networked devices together
learns what devices are on each port
forwards traffic based on MAC address
provides more security and uses bandwidth more efficiently
Router - CORRECT ANSWERS ✔✔Connects different networks together
Intelligently forwards traffic to and from network based on logical address
Use IP to determine routing of traffic
Wide Area Network (WAN) Link - CORRECT ANSWERS ✔✔Physically connects
networks together
Several types:
DSL, Cable, Fiber Optic, Satellite, Cellular, microwave, leased lines
Connects internal networks to external EX: home to ISP
,Client / Server Network Model - CORRECT ANSWERS ✔✔Dedicated server to
provide network resources to clients
Benefits:
Centralized
Easier to manage
More Scalable
Drawbacks:
Expensive
Requires dedicated resources
Requires network operating system
Peer to Peer network model - CORRECT ANSWERS ✔✔PCs share network
resources directly with each other
Benefits:
Low cost
No required dedicated resources
No special operating systems required
Drawbacks:
Decentralized
Inefficient the larger it gets
Can't really be scaled
,Personal Area Network (PAN) - CORRECT ANSWERS ✔✔Smallest type of wired
network
Covers a few meters
EX:
Bluetooth
USB drive
Local Area Network (LAN) - CORRECT ANSWERS ✔✔Connects components in a
limited space
Each segment has limited distances EX: 100m with Cat5 cables
Consists of IEEE Ethernet 802.3 or WIFI networks 802.11
Campus Area Network (CAN) - CORRECT ANSWERS ✔✔Connects Building
Centric LANs across a university or business park
Covers many square miles and buildings
EX:
College Campus
Business Parks
Military Bases
Metropolitan Area Networks (MAN) - CORRECT ANSWERS ✔✔Connects scattered
locations across a city
, Larger than CAN but smaller than WAN
Covers up to 25 mile radius
EX:
City Departments like the police dept
Community college campuses spread out across a county
Wide Area Network (WAN) - CORRECT ANSWERS ✔✔Connects geographically
dispersed internal networks
Consists of leased lines or VPNs tunneled over the internet
Covers distances around the country or around the world
EX:
The internet
Connecting to large corporate networks one in Seattle one in new York
Physical network topology - CORRECT ANSWERS ✔✔how devices are physically
connected by media
Logical network topology - CORRECT ANSWERS ✔✔how the actual traffic flows
through a network
Bus topology - CORRECT ANSWERS ✔✔Use a cable running through area that
required network connectivity
