What is Network Operating system

What are some benefits of software
It is suitable for the specific industry
Roaming licenses means you can use the tool on any networked devices
Some benefits of hardware
it is more suitable to intensive tasks
it can easily balance cost vs benefits
enhanced features
Drawbacks of hardware and software
Cost of implementation

Mention four different types of RAID
RAID 0
RAID 1
RAID 10
RAID 5
What is RAID 0
It is the type of raid that does not add any redundancy to your system and is only focused on speed
What is RAID 1
This maintains the original speed but doubles the redundancy
What is RAID 10
This is when you are utilising both the speed of “striping” and the redundancy “mirroring”
What is RAID 5
This is where we maximise speed with a small amount of redundancy via a process called “Parity”
What is a network
A network is a series of computers linked together in some way
List some different connection types
Wi-Fi
Ethernet/Fiber optic
Bluetooth
LiFi
What is Ethernet
Ethernet is the cable that connects the computers to the internet
What is LiFi
