Answer: keeps confidential documents secure,
displays a GUI, allocates the computer's resources, and retrieves files
Explanation:
The operating system can be defined as the software installed in the system that provides the information and services to the users by controlling the hardware, software resources, and regulates the computer programs. It runs the applications and programs in the system, displays the graphic user interface for the services, stores, manipulates, and retrieves files.

Formatting can maybe be applied to software works
Hey there! Hello!
In an instance of Microsoft Excel 2016, you can select your entire worksheet by using the Ctrl-A shortcut on your keyboard for Windows, or Command-A in the case of a Mac. If you have a standard Windows keyboard, you should have two Ctrl keys on either side of your keyboard. On a standard Mac keyboard, you'll also find that there are two Command keys on either side of your space key. This shortcut applies to other things as well, such as documents in Word. It basically selects everything there is to select.
I have attached a screenshot of the result of doing Command-A on a blank document. Everything within the bolded green outline is selected – it's typical for the cell you were on to be white instead of your highlight color (which is grey, in my case), and it will be selected, too.
Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)
Answer:
Two systems are connected by a router. Both systems and the router have transmission rates of 1,000bps. Each link has a propagation delay of 10ms. Also, it takes router 2ms in order to process the packet (e.g. decide where to forward it). Suppose the first system wants to send a 10,000 bit packet to the second system. How long will it take before receiver system receives the entire packet.
Transmission time for first Router = 10,000 bits / 1000 bps = 10 seconds
Receiving time for seond route r= 10,000 bits / 1000 bps = 10 seconds
Propagation delay = 10ms = .01 seconds x 2 for two delays = .02 seconds
First router 2ms to process = .002 seconds
Add all the times together and we get 20.022 seconds which is the same as or 20 seconds and 22 ms
