Networks

Question 1

What is a peer to peer network

Answer 1

all devices are EQUAL, connected to every other device (no central location)
Files are stored individually on machines and then share with others

Question 2

What is a client network

Answer 2

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

Question 3

Pros of peer to peer

Answer 3

Cheap

Easier to set up and maintain

Question 4

Pros of client server network

Answer 4

Central locatiom for all files

Easier to install and manage and perform back up of all stored data

Question 5

Cons client server network

Answer 5

Expensive to set up and maintain

If server fails then all connected devices will stop

Question 6

Cons of peer to peer

Answer 6

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

Question 7

Pros of a wired network

Answer 7

much more reliable, faster and stable connection (not affected by interference) and also less like to be affected by hacking

Question 8

Cons of a wired network

Answer 8

However, wired connections affect portability/movement and are cost more to add additional devices.

Question 9

Pros or a wireless network

Answer 9

easier to connect more devices, can move around and costs less vs wired.

Question 10

Cons of a wired network

Answer 10

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.

Question 11

Pros of the cloud

Answer 11

access data from any connected device, easy to increase storage, no need to pay extra for IT staff, provides auto updates and back-ups

Question 12

Cons of cloud

Answer 12

MUST need internet to access, dependency on the cloud host for security and back-ups, often subscription based so more expensive

Question 13

What is the cloud

Answer 13

host stores the data of another organisation, using its own servers, storage and software, accessible only via the internet.

Question 14

The perfomance of bandwidth means ?

Answer 14

higher bandwidth means better network performance as more data can be transferred at any given time. More users sharing bandwidth can slow down performance.

Question 15

The perfomance of connection type means ?

Answer 15

wired connections are more reliable/faster than wireless, but are not as portable and requir

Question 16

The perfomance of number of devices to a network means ?

Answer 16

the more devices connected, the slower the network may perform

Question 17

What does a DNS do ?

Answer 17

Translates a websites do ain name into its ip address so we dont need to rember ip addresses
