Adv of embedded systems
Small size - easy to fit into devices
Consume less power
Relatively low cost to make - compared to other systems
Can be controlled remotely
PS CC
Disadv of embedded systems
Can be difficult to upgrade to take adv of new tech
Since it can be accessed over the internet it can be hacked/get a virus
Very wasteful - since they’re difficult to upgrade
Only a specialist can troubleshoot errors in an embedded system
