What type of desktop system is sarah using in the following scenario? sarah types the phrase “open document 3” onto a black screen, and the computer responds by opening the file she requested. direct user interface indirect user interface command-line interface graphical user interface

I'd go with command-line interface.

A CLI enables users to type commands in a console or a terminal window expressed as a sequence of characters and presses the enter key on the keyboard to execute that command. And in this case, Sarah is typing an “open document 3” command to the command-line interface to open a file in her computer.

assuming you are in the home page.

1) go to the upper right hand corner

2) click on your "profile picture"

3) go down to "edit profile"

4) it should be titled as "edit your profile", click on "profile picture"

5) choose a file

6) press "change"

you're profile picture is updated
