You need to protect sensitive files from unauthorized users even if the disk is stolen. What feature should you use and on what
Lynna [10]

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.

_____ is typically used to temporarily hold small units of program instructions and data immediately before, during, and after e
guapka [62]

Answer:

A register

Explanation:

Registers are small memory used to store data or values and supply them to the processor as and when needed. These register hold the data temporarily and hold small units of program instructions. So whenever the CPU wants to work on data they have to be made available through the registers. Even after a arithmetic operation the registers serve as buckets for holding the value.

There are different types of registers such as register A, B, C etc and these registers lie in close proximity to the CPU so that we could provide the data immediately and much faster when asked by the CPU.

Therefore we can say that registers are used to temporarily hold small units of program instructions and data immediately before, during, and after execution by the central processing unit (CPU).

dem82 [27]

Answer:

Variable       Where Declared

In Sub1 :

        A        Sub1

        Y        Sub1

        Z        Sub1

        X        Main

In Sub2:

        A        Sub2

        B        Sub2

        Z        Sub2

        Y        Sub1

        X        Main

In Sub3 :

        A        Sub3

        X        Sub3

        W       Sub3

        Y        Main

        Z        Main

Explanation:

In static-scoped languages with nested subprograms, the declaration of a variable is checked with the subprogram, if it is not found, it check within the parent method that called it, it continue until it find a declaration, if no declaration is found, it display an error.

In Sub1, a, y, z is declared there while the declaration of x is found in main.

In Sub2, a, b, z is declared, declaration of y is found in sub1 and declaration of x is found in main.

In Sub3, a, x, w is declared while the declaration of y, z is from the main.
