Infrastructure Flashcards
Name the 2 types of Network resources
1) Client/Server Model
2) Peer to peer model
How does the client/server model work?
A) Uses dedicated server to provide access to files, scanners, printers, and other resources
Name 3 Benefits of Client/ Server model
1) Administration and back up are easier because the resources are located on a few key servers.
2) easier to manage
3) Better adaptability (scalability)
Name 3 drawbacks of Client/ Server model
1) it is very expensive to maintain
2) you have to dedicate many resource to keep maintaining it.
3) it will not function without a network operating system.
How does the peer to peer model work?
It works when one or more PCs (peers) share resources like files or printers with each other directly.
Name 3 Benefits of Peer to Peer model
1) to maintain it is very cheap
2) you don’t put many resources behind it to maintain it
3) you do not need any operating system to keep it functioning the way you want.
what are the drawbacks of peer to peer model?
1 )Administration and back up here is very difficult since all the resources they are sharing are located on more than one PCs which adds to the administrative burden
2) It is very inefficient for large networks
3) it has poor adaptability (scalabiity)
Name the 5 Major network Geography
1) LAN
2) CAN
3) WAN
4) MAN
5) PAN
What does PAN stand for?
Personal Area Network
How does PAN operate?
PAN operates within our personal space. it is a wireless network within our personal space.
What distance PAN covers?
PAN covers few meters within our personal space.
Give some examples of a PAN device
1) Bluetooth cell phone connected to car
2) using a USB drive to your laptop
3) using a fire wire video to your computer
What does LAN stand for?
Local Area Network
How does LAN operate?
LAN operates by connecting computers and it components in a short or limited distance.
What distance LAN covers?
100 meters with CAT 5 cabling
What does LAN consist of?
LAN consist of IEEE 802.3 OR
IEEE 802.11
Give some examples of a LAN device
1) Wireless Network
2) wired internal Network
What does CAN stand for?
Campus Area Network
How does CAN operate?
CAN operates by connecting buildings with LAN network together across a university campus or a business industrial park
What distance CAN covers?
many square miles and many buildings
Give some examples of where we usually find CAN networks
1) college campus
2) Business Parks
3) Military bases
What does MAN stand for?
Metropolitan Area Network
How does MAN operate?
MAN operates by connecting scattered networks in various locations across a city.
What distance MAN covers?
up to 25 mile radius in larger cities
