Are file permissions considered a bit mask?
a bit mask is the subtracted value that would allow you to obtain the actual file permission.
For example,
consider that a file permission of 777 gives everyone full permissions
You want the default file permission for all files created to be 755
You would then set your umask value to 022
Think about it in binary. File permissions consist of three 3-bit numbers, whose values can range from 000 (decimal 0) to 111(decimal 7)
111 111 111 (full permissions, or, 777)
-000 010 010 (subtract bit mask of 022)
-------------------
111 101 101 (actual file permissions 755)
your default bit mask on linux is set in either /etc/bashrc or /etc/profile. If you want to set it for a single person, you could do it in your .bashrc or .profile in your home directory.

Can you get files back after you delete them?
its possible if you havent erased or formatted your drive
YES with undelete software. This can be down loaded from MajorGeeks.com or you can purchase software to do this. Find the actual file in the directory, right click on it and select "delete". A confirmation question may appear, click on yes, and it's gone. Actually, it isn't really gone, rather it goes into the "recycle folder" and sits there until it is blasted away by you later on.

Why is open ckt test conducted on lv side?
in the open circuit test, the high voltage winding is open circuited and the measurements are made on the low winding side i.e, the open circuit test is performed on the L.V side. This is because if the measurements are made on HV side then voltage applied must be large and the current would be unsuitably small, for which the high voltage sources may not be readily available and at the same time the instrument ranges required should be very high, Also the result obtained may not be accurate.
NOTE: iron loss will be same, if measured from either of the winding.
in short circuit test. the low voltage winding is short circuited and the measurements are made on the high voltage winding side i,e,. the sort circuit test is performed on H.V side. This is because if the test is performed on the L.V side, the current will be suitably large for which the instruments used should be of very high ranges. moreover instruments of such high ranges and the auto-transformer capable of handling such high currents may not be readily available.
Do computer users have rights?
Depending on the circumstances, yes, computer users do have rights. There is supposed to be a certain amount of privacy, though that is under constant threat. People who create things on the computer have copyright protections. If you have problems online, you nearly always have the right to complain - though that might not always help.

If your computer becomes overwhelmed by too much spyware or adware it can come to a screaching halt. Use these 2 programs on a weekly basis! Commuter :) If you take off your start-up programs, it may help. On windows XP go to the start button, run and type in msconfig. At the top of the window there are tabs choose the tab that says start-up. Uncheck everything it will not harm your computer. Click apply then ok. It will tell you to reboot your computer when it reboots a window will appear that states "You are using selective start-up" there is a box in the middle of the window that says "Do not show this messge again" click that. Good Luck!
What is higher order address of a 16 bit address?
In the 8085, the high order address is A8-A15. In the 8086/8088, the high order address is A8-A19. (For a 16-bit address, the answer is A8-A15, but the answer above reflects the chosen categories, 8085 and 8086/8088, with the 8086/8088 running in 20-bit mode.) In Windows XP, running in 32-bit mode, the high order address is A8-A31, a 32 bit address.
