Answer:
Explanation:
Run: Choose Run when you only need the download once. Perhaps it’s a song or video you only plan to listen to or watch once. Another scenario might be an installation program that, when run, installs software on your machine in other, permanent locations. Once installed, you probably don’t need the installer again.
Save: When you want to keep whatever it is you’ve downloaded, choose Save. You can still run it, or whatever else you’d like to do with it, but you’ll need to do that yourself. You’ll also want to decide where, on your computer, to keep the file.
<em>Save and run: Use this option when you want to do both: save the file to a location you control, and then immediately run it.

Answer:
vulnerability, risk
Explanation:
A vulnerability would be a misconfiguration of a system that allows the hacker to gain unauthorized access, whereas a risk is a combination of the likelihood that such a misconfiguration could happen, a hacker’s exploitation of it, and the impact if the event occurred.
Use the following rules:
- The sum of currents that enter and exit a node (junction) is always zero. So if you have 3 wires that connect, through one flows 2A, the other 3A, then the third must deliver 5A (taking the direction into account!)
- The sum of voltages across different components should always add up. So if you have a battery of 10V with two unknown resistors, and over one of the resistors is 4V, you know the other one has the remaining 6V.
- With resistors, V=I*R must hold.
With these basic rules you should get a long way!
Answer:
The control unit of the CPU contains circuitry that uses electrical signals to direct the entire computer system to carry out stored program instructions.
Explanation: The control unit does not execute program instructions rather, it directs other parts of the system to do so.
Answer:
Interference.
Explanation:
As the user is communicating with their friend through the mobile, most of their interaction is interrupted by the noise of an airplane flying at low hight. Instantly afterward, the user's mobile phone rang, disrupting the communication once more.
So, according to the following scenario both of those are examples of interference.
