Hello,
Well my advice for Sara when using the web would be 3 things.
1: Never tell anyone where you live,Your name, Or any other personal information.
This is important as it will keep you safe and others that are in your family.
2: Get anti virus hardware on your devise.
This will help to stop bad people, and bugs/glitches,this will also protect you from information thieves.
3: Make sure to keep your passwords saved on paper.
I know a lot of people use, google(ect.) to save there passwords to make everything easy, but a good way to never loss them is to wright them down.
Have a great day!
Answer:
In a STAR TOPOLOGY network, each device on the network is attached to a central router. If the router fails, then the other devices will be unable to communicate, but if only one connected device fails, then all other devices will still be able to communicate.
Explanation:
In this type of topology all the computers are connected to a single router through a cable. This router is the central node and all others nodes are connected to the central node.
