Consider a computer system with three users: alice, bob, candy. alice owns the file alicerc, and bob and cyndy can read it. cyndy can read and write the file bobrc, which bob owns, but alice can only read it. only cyndy can read and write the cile cyndyrc, which she owns. assume that the owner of each of these files can execute it.
a. create the corresponding access control matrix.
b. cyndy gives alice permission to read cyndyrc, and alice removes bob's ability to read alicerc. show the new access control matrix.

if you have a hp laptop on the top row of your keyboard there sould be a button that says prt sc , click that then wait a second then open the paint app open the clipboard and hit paste then save as a file. hope that ^-^

the printer can be used in a both wired and wireless network, only one of the connection methods can be used at one time when the wireless setting is enabled, the wired (ethernet) setting is disabled.

`connect the cord to your computer

`open settings app from the start menu

`click devices

`than click add printer or scanner

and than you should be able to do it from there, if not let me know i can you! : )
