Answer:
Option is b is correct answer. Excel performs exponentiation, then multiplication and division, then addition, and subtraction, it is correct order of operation in Excel. It is important to remember when you write any formula in Excel having different mathematical operators like +/ -/ ^/ etc, it follows a specific order and performs calculations in specific order which is termed as order of operator precedence. Each of mathematical operator has its precedence and executes in a special order set by Excel.
Explanation:
- As we already know order of precedence of each mathematical operator is different in Excel. The order of operations for Excel is as follows:
- Evaluate elements in parentheses.
- Evaluate 'ranges' ().
- Evaluate 'intersections' (empty spaces).
- Evaluate 'unions' (,).
- Perform negation (-).
- determine percentages (%).
- Perform exponentiation (^).
- Perform multiplication (*) and division (/), both are of equal precedence.
- Perform addition (+) and subtraction (-), both are of equal precedence.
- Evaluate text operators like (&).
- Perform comparisons like (=, <>, <=, >=).

Basically no boot device could be 1 of three things listed below.
1. You have connected an incorrect external device and the system responds to boot from this however no operating system is available. Hence the error. What to do : You have disconnect, reset and select the correct bootable device.
2. You have a faulty hardware specifically your bootable harddisk, corrupted or malfunctioning. You have to reformat and correct the bios installed on the disk.
3. You have not selected correct bootable device. - Select the correct harddisk, if you have partition, be sure to select the one with the Operating system is installed to.
Answer:
Option A.
Explanation:
In 3D computer graphics, this process determines which elements should not be visible from the desired point of view, and will prevent them from rendering. Thus, objects that lie behind opaque surfaces such as walls or panels, will not be rendered.
A good rendering algorithm helps to optimize the graphic engine because it will load as few elements as possible. Therefore, in larger worlds, the engine will remain at a stable speed and will be more efficient.
Answer:
EFS on NTFS
Explanation:
EFS (Encryption File System) allows users to store confidential information about a computer when people who have physical access to your computer could otherwise compromise that information, intentionally or unintentionally. EFS is especially useful for securing sensitive data on portable computers or on computers shared by several users. An attacker can also steal a computer, remove the hard drive(s), place the drive(s) in another system, and gain access to the stored files. Files encrypted by EFS, however, appear as unintelligible characters when the attacker does not have the decryption key.
The Encrypting File System (EFS) that is included with the operating systems provides the core file encryption technology to store NTFS files encrypted on disk.
