Which of these is NOT hardware used to create a network?
Hub
SSD
Wireless Access Point
Switch
'Witches use switches' helps us to remember that...
Switches forward data 'intelligently'
Switches work by magic and spells
Switches are efficient, but not as much as hubs
Switches use CAT5 Ethernet and witches usually have a cat
Which of these statements about Clients and Servers is FALSE?
Servers sometimes have a 'failover' partner as a backup.
Servers can authenticate log-ins
Clients usually have more storage space than servers
Clients can use software running on servers
Which of these is NOT an advantage of networking computers?
Printers can be shared
Fewer cables are needed
Files are easier to share
Installs can be done on many computers at once
Which one of these should NOT slow down the performance of a network?
Lots of users on at once
Everyone on WiFi instead of cabled connections
Lots of malware infections
Using fibre optic cable to join different parts together
Which of these is true about peer-to-peer networks?
They are illegal
Resources are not held on a central server
They are mainly used on the 'dark web'
They are only used with a home hub.
Why are there about 20 wireless access points around school?
We got a really good price for buying in bulk
They have short ranges, so you need them every 30 metres or so
Because there are more students with phones these days
Every extra one makes the WiFi stronger.
A network interface card is...
A card used to join two networks
Hardware that joins a device to a network
Like a business card used at networking meetings
Used to send greetings on National Network Interface Day

What is the 'client' part of a network?
A device such as a switch or a router that works for the network.
A server providing a service to workstations on a network.
A workstation, network node or node.
The ISP - Internet Service Provider.
Choose the best definition to explain what is meant by a 'peer-to-peer' network.
Computers have equal status and do not rely on a central server. Each workstation is effectively both a server and client.
A client is used to make requests, the server processes these requests and then responds to the request. The server provides a service.
Select all the true statements:
There needs to be a server for each client to save and manage each workstation's data.
Peer-to-peer networks are easier to set up than client-server networks
Peer-to-peer networks allow individual devices to share files between each other.
Peer-to-peer networks are commonly used in large organisations
It is easier to implement security procedures throughout a client-server network than a peer-to-peer network.
A distributed networking model without servers, where connected computers can act as both clients and servers at the same time.
peer-to-peer network
client-server network
Virtual Private Network
Wide Area Network
