What is block chain?

Answer:

IT infrastructure

Explanation:

and their IT infrastructure through physical security measures. There are two main ways of "hacking" a system. One is through a flaw in the software that is someone skilled enough can manipulate in order to gain access to the system and retrieve data or manipulate the system as they see fit. The second method is physically by accessing the IT infrastructure. If you were able to do so and there are no physical security measures you could simply plug into the infrastructure and access all the information that you want because you would be completely bypassing the digital security measures by doing so. That is why physical security measures are placed so that only qualified and vetted individuals have access to the infrastructure.

Answer:

Where are options?

Explanation:

An operating system (OS) is a piece of software that executes other applications and programs on a computer while controlling and coordinating the hardware components. It is the core component of the system software, and without it, a computer cannot operate.

A computer is a device that may be configured to automatically perform series of mathematical or logical operations (computation). Modern digital computers are capable of running programmes, which are generalised sets of operations. These apps give computers the ability to carry out a variety of tasks. A computer is a minimally functional computer that contains the peripheral devices, system software (primary software), and hardware required for proper operation. This phrase may also apply to a collection of connected computers that work as a unit, such as a network or group of computers. The sole purpose of early computers was to perform computations. Since ancient times, simple manual tools like the calculator have supported humans in performing computations.

How has the shift to locally grown produce decreased greenhouse emissions? 1 Large farms often create greenhouse emissions by poor farming practices. 2 Locally grown produce allows fewer dangerous toxins to seep into the soil and the atmosphere.

The code example that uses correctly a local variable inside a function to mask (hide) it from a global variable is:

int i = 5;

void function (){

...

for(int i = 0; i < 13; i++)

}

Local variables are variables that have the scope only inside the function that it was declared.

Global variables are variables that have an entire program as a scope.

If a global variable is "re-declared" inside a function, then the scope is only the function, meaning that the local variable inside the function hides it from the global variable.

This is the case in the code we gave for this problem, in which:

Answer: The Answer should be D

Explanation: It's the definition.

Based on the information provided, we can start generating possible six-digit password combinations by considering the following:

   The password contains one or more of the numbers 2, 6, 9, 8, and 4.

   The password has a double 6 or a double 9.

   The password does not include 269842.

One approach to generating the password combinations is to create a list of all possible combinations of the five relevant numbers and then add the double 6 and double 9 combinations to the list. Then, we can eliminate any combinations that include 269842.

Using this method, we can generate the following list of possible password combinations:

669846

969846

669842

969842

628496

928496

628492

924896

624892

924892

648296

948296

648292

948292

Note that this list includes all possible combinations of the relevant numbers with a double 6 or a double 9. However, it is still possible that the password is something completely different.

Explanation:

a) The converted binary numbers are:

1.AB2 base in 16 =  2738

2.123 in base 16 = 291

3.ABB base 16 = 43787

4.35E.E base 16​ =  3.3671875

b) converted  binary numbers to decimals are:
237 in base 8 = 159

2731 in base 8 = 1497

617.7 in base 8 =  7.234375

22.11 in base 8 = 0.15625

c) The two's complement representations of the following numbers using 8bit are:

-17 = 11101111.

-11 = 11110101.

-46 = 11010010.

-78 = 10110010.

1) Converting binary numbers to decimal:

AB2 base in 16:

The first digit from the right is 2, which represents 2 in decimal.

The second digit from the right is B, which represents 11 in decimal.

The third digit from the right is A, which represents 10 in decimal.

Therefore, AB2 base 16 in decimal is: 2 + 11x16 + 10x16^2 = 2 + 176 + 2560 = 2738

2) 123 in base 16:

The first digit from the right is 3, which represents 3 in decimal.

The second digit from the right is 2, which represents 2 in decimal.

The third digit from the right is 1, which represents 1 in decimal.

Therefore, 123 base 16 in decimal is: 3 + 2x16 + 1x16^2 = 3 + 32 + 256 = 291

3) ABB base 16:

The first digit from the right is B, which represents 11 in decimal.

The second digit from the right is B, which represents 11 in decimal.

The third digit from the right is A, which represents 10 in decimal.

Therefore, ABB base 16 in decimal is: 11 + 11x16 + 10x16^2 = 11 + 2816 + 40960 = 43787

4) 35E.E base 16:

The first digit from the right is E, which represents 14 in decimal.

The second digit from the right is ., which separates the integer and fraction parts.

The third digit from the right is 5, which represents 5 in decimal.

The fourth digit from the right is 3, which represents 3 in decimal.

The fifth digit from the right is E, which represents 14 in decimal.

Therefore, 35E.E base 16 in decimal is: 14/16 + 3x16^-1 + 5x16^-2 + 14x16^-3 = 14/16 + 3/16 + 5/256 + 14/4096 = 3.3671875

Converting binary numbers to decimal:

1) 237 in base 8:

The first digit from the right is 7, which represents 7 in decimal.

The second digit from the right is 3, which represents 3 in decimal.

The third digit from the right is 2, which represents 2 in decimal.

Therefore, 237 base 8 in decimal is: 7 + 3x8 + 2x8^2 = 7 + 24 + 128 = 159

2) 2731 in base 8:

The first digit from the right is 1, which represents 1 in decimal.

The second digit from the right is 3, which represents 3 in decimal.

The third digit from the right is 7, which represents 7 in decimal.

The fourth digit from the right is 2, which represents 2 in decimal.

Therefore, 2731 base 8 in decimal is: 1 + 3x8 + 7x8^2 + 2x8^3 = 1 + 24 + 448 + 1024 = 1497

3) 617.7 in base 8:

The first digit from the right is 7, which represents 7 in decimal.

- The second digit from the right is ., which separates the integer and fraction parts.

- The third digit from the right is 1, which represents 1 in decimal.

- The fourth digit from the right is 6, which represents 6 in decimal.

- Therefore, 617.7 base 8 in decimal is: 7/8 + 1x8^-1 + 6x8^-2 + 0x8^-3 + 0x8^-4 + 0x8^-5 + 0x8^-6 + 0x8^-7 = 7/8 + 1/8 + 6/64 = 7.234375

4) 22.11 in base 8:

The first digit from the right is 1, which represents 1 in decimal.

The second digit from the right is 1, which represents 1 in decimal.

The third digit from the right is ., which separates the integer and fraction parts.

The fourth digit from the right is 2, which represents 2 in decimal.

Therefore, 22.11 base 8 in decimal is: 1x8^-1 + 1x8^-2 + 2x8^-3 + 0x8^-4 = 0.140625 + 0.015625 = 0.15625

Finding the two's complement representation of the following numbers using 8-bit:

To find the two's complement of a negative number, we first need to represent the number in binary form, invert all the bits, and then add 1 to the result.

a) -17:

- The binary representation of 17 is 00010001.

- Inverting all the bits gives 11101110.

- Adding 1 to 11101110 gives 11101111.

- Therefore, the two's complement representation of -17 in 8-bit is 11101111.

b) -11:

- The binary representation of 11 is 00001011.

- Inverting all the bits gives 11110100.

- Adding 1 to 11110100 gives 11110101.

- Therefore, the two's complement representation of -11 in 8-bit is 11110101.

c) -46:

- The binary representation of 46 is 00101110.

- Inverting all the bits gives 11010001.

- Adding 1 to 11010001 gives 11010010.

- Therefore, the two's complement representation of -46 in 8-bit is 11010010.

d) -78:

- The binary representation of 78 is 01001110.

- Inverting all the bits gives 10110001.

- Adding 1 to 10110001 gives 10110010.

- Therefore, the two's complement representation of -78 in 8-bit is 10110010.
