Networks Flashcards
What is a peer to peer network
all devices are EQUAL, connected to every other device (no central location)
Files are stored individually on machines and then share with others
What is a client network
is managed by one main server, and it is connected to all its devices (clients)
Files and software are stored on the server, instead of individual client machines
Pros of peer to peer
Cheap
Easier to set up and maintain
Pros of client server network
Central locatiom for all files
Easier to install and manage and perform back up of all stored data
Cons client server network
Expensive to set up and maintain
If server fails then all connected devices will stop
Cons of peer to peer
No centralised location (requires manual back-ups and updating of software)
Copying files creates duplicates of files, so harder to keep track of latest versions
Less reliable and data may be lost if one machine fails
Pros of a wired network
much more reliable, faster and stable connection (not affected by interference) and also less like to be affected by hacking
Cons of a wired network
However, wired connections affect portability/movement and are cost more to add additional devices.
Pros or a wireless network
easier to connect more devices, can move around and costs less vs wired.
Cons of a wired network
However, more devices means affected by interference, it is not as fast or stable as a wired (Ethernet) connection and is more prone to be affected by hacking.
Pros of the cloud
access data from any connected device, easy to increase storage, no need to pay extra for IT staff, provides auto updates and back-ups
Cons of cloud
MUST need internet to access, dependency on the cloud host for security and back-ups, often subscription based so more expensive
What is the cloud
host stores the data of another organisation, using its own servers, storage and software, accessible only via the internet.
The perfomance of bandwidth means ?
higher bandwidth means better network performance as more data can be transferred at any given time. More users sharing bandwidth can slow down performance.
The perfomance of connection type means ?
wired connections are more reliable/faster than wireless, but are not as portable and requir
