Answer:

B. XOR

Explanation:

Logic gates are practical implementation of a digital circuit. There are three basic logic gates, namely; AND, OR and NOT gates. Every other gates are derived from them.

XOR, also called exclusive OR is derived from the OR gate. It gives a high output ( ON or '1') when the inputs are odd (that is, it gives one value or ON state when one of a two-input gate is ON or high). The output for an even 'zero' or 'one' input, is a zero or off or low state.

To represent XOR for two inputs: A⊕ B⇒Y(output).

4. D

5. A

6. B

Explanation:

CPU: this is known as the central processing unit and it is considered to be the brain of a computer system. It is the system unit where all of the processing and logical control of a computer system takes place.

A. Decode unit: decodes instructions and data and transmits the data to other areas in an understandable format.

B. Register unit: contains many separate, smaller storage units. Modern CPUs need only a few nanoseconds to execute an instruction when all operands are in its registers.

C. Bus unit: it is used to connect all the other major components together, accepts data, and sends data through the input and output bus sections.

D. Control unit: control of the overall operations of the CPU. The component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit how to respond to informations sent to the processor.

E. Arithmetic logic unit (ALU): performs mathematical functions on data stored in the register area.

F. Cache: small temporary memory area that separates and stores income data and instructions.

just olya [345]

Answer:

TIGER TEAM

Explanation:

Penetration testing is the act of simulating an attack on an organization's resources to assess an infrastructure's true vulnerabilities. A penetration test simulates an actual attack. Penetration testers use a variety of methods including social engineering, software hacking and physical intrusion.

There are different types of penetration testing teams which are: red team, blue team and purple team.

Red team also known as the tiger team simulates real types of cyber attacks in order to discover any unknown security vulnerabilities or weaknesses.

In penetration testing, tiger (red) team are the attackers and are usually outside contractors, with a lot of knowledge of how to break in but NO KNOWLEDGE OF WHAT SECURITY IS IN PLACE.

Therefore, In a penetration test, the TIGER TEAM comprises testers who are given no knowledge of the infrastructure and are attacking a target that is unaware of their existence until the attack is made.

3. The wildlife department has been feeding a special food to rainbow trout finger lings in a pond. A sample of the weight of 40
andrey2020 [161]

Answer:

1)  402.7 grams. This estimate is called the sample mean.

2)  (399.11, 406.29)

3) The 99 percent confidence limits is between 399.11 grams and 406.29 grams.

I am 99% sure that the value lies between 399.11 grams and 406.29 grams.

Explanation:

sample size (n) = 40, the mean weight (x)= 402.7 grams and the standard deviation (σ)=8.8 grams

1) The point estimated mean weight of the population is 402.7 grams. This estimate is called the sample mean.

2) c = 99% = 0.99

α = 1 - 0.99 = 0.01

\frac{\alpha }{2} =\frac{0.01}{2} =0.005.

The z score of 0.005 corresponds with the z score of 0.495 (0.5 - 0.005).

z_\frac{\alpha }{2} =2.58.

The margin of error (e) = z_\frac{\alpha }{2}*\frac{\sigma}{\sqrt{n} }  =2.58*\frac{8.8}{\sqrt{40} } =3.59

The confidence interval = x ± e = 402.7 ± 3.59 = (399.11, 406.29)

3) The 99 percent confidence limits is between 399.11 grams and 406.29 grams.

I am 99% sure that the value lies between 399.11 grams and 406.29 grams.
