Answer:
Explanation:
some distros like ubuntu do not even allow su to switch to root. furthermore the su to root is dangerous because the user becomes the all-powerful administrative account, so no warnings are issued if the application team user tries to do something system-breaking.
Hey there! Hello!
So, not sure if there's actually a button to "close out" a window to where you're able to reopen it again without having to go to where the file is located or go to recents in your application. Keep in mind that I'm on a MacBook, but I have worked on a Windows computer before.
One thing you can do is minimize the window. Your program will remain open, but your window will remain out of your way until you decide to expand it again. This seems to be the closest thing possible to your description, but if you had something else in mind, I'd love to hear more details.
This won't be a good solution if you're looking to cut down on the energy that certain programs may be taking up while open, even if you're not using them. But in terms of getting the windows off your desktop, minimizing is the way to go. It also allows you to have documents/windows out of the way while still being able to work on other documents/windows in the program (i.e. Microsoft Word, Google Chrome, Pages, etc.)
Hope this helped you out! Feel free to ask me any additional questions you may have. :-)
Answer:
Total Memory= 4 KB = 4096 bytes = 32768 bits
Explanation:
<em><u>1. Data lines are 8 From D0 to D7</u></em>
so
Total memory at single address locations is 8 bits.
<em><u>2. Address lines are 12 (A0 to A11)</u></em>
There are 12 address lines but 3 out 12 are for selction of chip or memory bank.
so only 9 pins are there to address the locations on one chip.
Total No. of address locations on single chip = 2^9 = 512 locations
as 1 location is 1 byte so total memory of single chip is 512 bytes.
<u><em>3. Total Memory Bank </em></u>
There are total 3 selection pins for memory bank.
so
Total chips = 2^3 = 8.
<em><u>4. Total Memory </u></em>
Total size of 1 chip = 512 bytes
Total size of 8 chip = 8x512 bytes = 4096 bytes = 4096/1024 kb = 4 kb
<em>So total memory of system is 4 Kb = 4096 bytes = 32768 bits</em>
