Answer:

The minimum number of bits necessary to address 8K words is 13.

Explanation:

You have the number of words to address that is 8000 words, a word is the smallest addressable memory unit.  

8000 words can be addressed with [tex]2^{n}[/tex]  units. Now you have to find the value of n that approximates to the number of words.  

[tex]2^2=4\\2^4=16\\2^7=128\\2^{10}=1024\\2^{12}=4096\\2^{13}=8192[/tex]

So you can see that 13 bits are needed to address 8K words.

Answer:

Option D is correct.

Explanation:

A high-level safety violation could be anticipated to have a serious or disastrous negative impact on organisational activities, organisational assets.

The effect of the violation on an organisation may be staggering, and sometimes unknown until the outcomes are achieved. It is strange that, owing to harmful or neglectful acts, the greatest incidents of compromise come from within the business ; it requires time for an organisation to recover.

A high-level security breach might have a serious or catastrophic impact on an employee's performance, assets, or people.

The impact of a violation on such an organization may be enormous, and the consequences are often unclear until they are realized.

It's odd that the majority of incidences of breach occur within the company as a result of damaging or negligent behavior; it takes time for an organization to recover.

C.  corrective

Explanation:

Security controls

These are actions or measures taken to maintain and/ or restore the security of the system. Security controls are categorized as corrective, preventive and detective, which are discussed below.

Corrective

Security controls which help in taking the corrective steps after the malicious activity has done damage to the system or restoring the security of the system are called corrective security controls.

These controls also act as preventive measures for future risks.

These controls perform the healing and have remedial action for the damage done to the system.

Once the system has been recovered, appropriate measures are put in place to avoid further damage.

The damage can be done to the computer system, its hardware and software resources or the data.

Examples include restoring the database from the backup file.

Updating or renewing antivirus software rectifies the security against virus.

For example, once the database has been restored, access control, antivirus and other measures are employed to prevent the database from being corrupted and to prevent system from being affected.

Preventive

Security controls which help in stopping the malicious activity from harming the system are called preventive security controls.

As per the name, these measures are employed to prevent any security breach.

These measures prevent any suspicious activity from taking place which may cause harm to the system.

Firewalls prevent unauthorized access.

Antivirus prevents malicious applications from running.

Login feature to give access only to authorized user.

Detective

Security controls which help in detecting the malicious activities and alerting the security personnel are called detective security controls.

As per the name, these measures are used to identify any suspicious activity and report them. Detective controls do not prevent or correct any security breach.

Alarms are employed to detect and alert any suspicious activity.

Intrusion detection system (IDS).

In an ideal situation, security controls are a combination of all the types mentioned above.

The type of security control involving measures that restore a system is referred to as: c. corrective.

A corrective security control can be defined as the type of security control measures that includes technical, administrative and physical measures which are initiated to help restore a system to its original state after a breach or an unauthorized activity has occurred.

Therefore, the type of security control involving measures that restore a system is referred to as: c. corrective.

3D ( in hexadecimal )

Explanation:

Converting the given hexadecimal numbers to decimal:

 67 (HEX) = 16*6 + 7 = 103 (Decimal)

 2A (HEX) = 2*16 + 10 = 42 (Decimal)

Subtracting the two numbers: 103 - 42 = 61 (Decimal)

Converting the result to Hexadecimal format:

61 = 16* 3 + 13

13 corresponds to D in hexadecimal.

So result in hex is 3D.

To summarize, the subtraction result for the two given hexadecimal numbers is 61 in decimal format or 3D in hexadecimal.

Answer:

The correct answer for the given question is option(A) and option(C) .

Explanation:

To declared any variable of character we using following syntax

char variable=' value';

char  letter='w';

In option(A)  their is no single quotes between character w .So this is not a valid assignment.

In option(C) their is double quotes between character w,no single quotes  between character w .So this is not a valid assignment.

In option(B) their is single quotes between character w .So this is a valid assignment.

So option(A) and option(C) are are not valid assignment statement.

A) Valid if `w` is a `char` variable.

B) Valid (`'w'` is a `char` literal).

C) Invalid (`"w"` is a `String`, not a `char` literal).

In Java, a `char` variable can only be assigned a single character enclosed in single quotes (e.g., `'a'`, `'b'`, `'w'`). Therefore, valid assignment statements must adhere to this rule.

Let's analyze each option:

A) `letter = w;`

- This statement assumes `w` is a variable holding a `char` value. If `w` is not declared as a `char` and does not represent a valid character literal, this assignment will cause a compilation error.

B) `letter = 'w';`

- This is a valid assignment statement. `'w'` is a character literal representing the character 'w'. It matches the type `char`.

C) `letter = "w";`

- This statement uses double quotes, which in Java denote a `String` literal, not a `char` literal. Therefore, this assignment will cause a compilation error because you cannot directly assign a `String` to a `char` variable.

Conclusion:

The assignment statement that is not valid to assign the letter 'w' to a `char` variable in Java is **C) `letter = "w";`**.
