The correct answer is A. Tires are underinflated

Explanation:

Modern vehicles are equipped with systems that monitor different aspects in the car and show through lights if there is an issue, this includes low fuel level, open door,s issues with the battery and even inappropriate tire pressure.

This last aspect is monitored by the Tire Pressure Monitoring System that alerts drivers of inadequate tire pressure due to underinflated or overinflated tires through an illuminated symbol with a warning sign in the dashboard. Besides this, the Tire Pressure Monitoring System and the warning light is of vital importance because inadequate tire pressure decreases the efficiency of the car and can lead to tire failure and accidents. Thus, many vehicles have indicator lights telling you when your tires are underinflated.

Add the following 2's complement binary numbers. Also express the answer in decimal. a. 01+ 1011b. 11+ 01010101c. 0101+ 110d. 01

kenny6666 [7]

Answer:

(a) 01 + 1011

Convert the two numbers into their 4-bit representation.

=> 01 = 0001

=> 1011

Addition of the two numbers (in their 2's complement form) gives the following:

0 0 0 1 ------------------> + 1 (in decimal)

1 0 1 1 ------------------> - 5 (in decimal)

1 1 0 0 -------------------> - 4 (in decimal)

Explanation for (a)

01 or 0001

Since the most significant bit is 0 (leftmost bit), it shows that it is a positive number. Therefore, it can be directly converted to its decimal representation as follows:

0001 = 0 x $2^{3}$ + 0 x $2^{2}$ + 0 x $2^{1}$ + 1 x $2^{0}$ = 1

0001 is + 1 in decimal.

1011

Its most significant bit(MSB) is 1 showing that it is negative.

Flipping all its bits and adding 1 to the result, will convert it to it's positive counterpart.

i.e 1011 => 0100 + 1 = 0101.

Converting the result (0101) to decimal gives

0101 = 0 x $2^{3}$ + 1 x $2^{2}$ + 0 x $2^{1}$ + 1 x $2^{0}$ = 5

1011 is -5 in decimal

01 + 1011 or 0001+ 1011 = 1100

The result (1100), of the addition of the two numbers, is a negative number as the MSB is 1.

Convert it to it's positive counterpart.

i.e 1100 => 0011 + 1 = 0100.

Converting the result (0100) to decimal gives

0100 = 0 x $2^{3}$ + 1 x $2^{2}$ + 0 x $2^{1}$ + 0 x $2^{0}$ = 4

Therefore, the result, 1100 is -4 in decimal.

===================================================

(b) 11 + 01010101

Convert the two numbers into their 8-bit representation since one of them is in 8-bit.

PS: Taking 11, its MSB is 1 showing that it is a negative number. Also, it's 8-bit representation will mean pre-padding it with ones(1s) rather than zeros as follows. In other words, pre-padding a 2's complement number is done using its sign bit.

=> 11 = 11111111

=> 01010101

Addition of the two numbers (in their 2's complement form) gives the following:

1 1 1 1 1 1 1 1 ------------------> - 1 (in decimal)

0 1 0 1 0 1 0 1 ------------------> + 85 (in decimal)

1 0 1 0 1 0 1 0 0 -------------------> + 84 (in decimal)

Discard the carry-out bit (1) making the result 01010100

Explanation for (b)

11 or 11111111

Its MSB is 1 showing that it is negative.

Convert it to it's positive counterpart.

11111111 => 00000000 + 1 = 00000001

Converting the result (00000001) to decimal gives 1

11 or 11111111 is - 1 in decimal.

01010101

Its MSB is 0 showing that it is also positive. Now, convert to decimal

01010101 = 85

01010101 is + 85 in decimal.

11111111 + 01010101 = 01010100

The result (01010100), is also positive as the MSB is 0. Now, convert to decimal.

01010100 = 84

Therefore the result (01010100) is + 84 in decimal.

===================================================

Convert the two numbers into their 4-bit representations.

=> 0101 = 0101

=> 110 = 1110

Addition of the two numbers (in their 2's complement form) gives the following:

0 1 0 1 ------------------> + 5 (in decimal)

1 1 1 0 -----------------> - 2 (in decimal)

1 0 0 1 1 -------------------> + 3 (in decimal)

Dicard the carry-out bit (leftmost bit) to get 0011 as result.

Explanation for (c)

0101

Since the MSB is 0 (leftmost bit), it shows that it is a positive number. Now, convert to decimal.

0101 = 5

0101 is +5 in decimal.

110 or 1110

Its MSB is 1 showing that it is negative.

Convert it to it's positive counterpart.

i.e 1110 => 0001 + 1 = 0010.

Converting the result (0010) to decimal gives

0010 = 2

1110 is -2 in decimal

0101 + 110 = 0101+ 1110 = 0011

The result (0011), is a positive number as the MSB is 0.

Converting the result (0011) to decimal gives

0011 = 3

Therefore, the result, 0011 is 3 in decimal.

===================================================

(d) 01 + 10

Convert the two numbers into their 4-bit representation.

=> 01 = 0001

=> 10 = 1110

Addition of the two numbers (in their 2's complement form) gives the following:

0 0 0 1 ------------------> + 1 (in decimal)

1 1 1 0 ------------------> - 2 (in decimal)

1 1 1 1 -------------------> - 1 (in decimal)

Explanation for (d)

01 or 0001

Since the MSB is 0 (leftmost bit), it shows that it is a positive number. Now convert to decimal.

0001 = 1

0001 is + 1 in decimal.

1110

Its MSB is 1 showing that it is negative.

Convert it to it's positive counterpart.

i.e 1110 => 0001 + 1 = 0010.

Converting the result (0010) to decimal gives

0010 = 2

1110 is -2 in decimal

01 + 1011 or 0001+ 1110 = 1111

The result (1111), is a negative number as the MSB is 1.

Convert it to it's positive counterpart.

i.e 1111 => 0000 + 1 = 0001.

Converting the result (0001) to decimal gives

0001 = 1

Therefore, the result, 1111 is -1 in decimal.

Write a program to help you feed your friends at a party by doing some math about square pizzas. Assume the grader defines a str

Nina [5.8K]

Answer:

Following are the program in the Python Programming Language.

#get input from the user length of the pizza

inputStr = input('Enter the length of pizza: ')

#convert input into float

L = float(inputStr)

#initialize the area of the pizza

A = L*L

#calculate the amount of peoples can eat pizza

men = int(A/100)

#print the number of peoples

print('\nPizza can be eaten by {} people'.format(men))

Output:

Enter the length of pizza: 20

Pizza can be eaten by 4 people

Explanation:

Following are the description of the program.

Firstly, set a variable that get length input from the user.
Set variable 'L' that convert the input from the user into the float data type.
Set variable 'A' that stores the area of the pizza.
Set variable 'men' that store the amount of peoples can eat pizza.
Finally, print the number of peoples can eat pizza.

Sonbull [250]

Answer:

The basic comaprism of OSSTMN and PTES includes the following: OSSTMN is more theoretical, security assessment methodology, and Metrics based why PTES is technology oriented, penetration testing methodology , extended analysis of all stages

Explanation:

Solution

Penetration testing has several methodologies which include :OSSTMM and PTES

The comparison between OSSTMM and PTES is stated as follows:

OSSTMM:

Security assessment methodology

More Theoretical

Metrics based

PTES :

Technology oriented

Penetration testing methodology

Extended analysis of all stages

Now,

There are 7 stages which is used to define PTES for penetration testing.(Penetration Testing Execution Standard)

Pre-engagement Interactions

Intelligence Gathering

Threat Modeling

Vulnerability Analysis

Exploitation

Post Exploitation

Reporting

Now,

The OSSTMM is used to obtain security metrics and performing penetration testing .The OSSTMM provides transparency to those who have inadequate security policies and configurations.

The OSSTMM includes the entire risk assessment process starting from requirement analysis to report creation.

Six areas are covered by OSSTMM which are:

Information security

Process security

Internet technology security

Communications security

Wireless security

Physical security

E-mail is an efficient means of disseminating information quickly and inexpensively. However, HIPAA regulations affect e-mail us

oksano4ka [1.4K]

Sending potentially sensitive information by email

Potentially sensitive information can be sent via Email only if the Email is encrypted

Explanation:

No doubt Email is an inexpensive efficient means of communicating quickly. But it is prone to hacking and it is not a secure mechanism. In order to add security ,the Email needs to be sent in an encrypted form. Banking and HIPAA regulations require the emails to be sent in encrypted form as it is a secure mechanism. Even if one has the consent from the client , the Email has to be in encrypted. Even if the Organization's e-mail system has appropriate firewalls and related infrastructure , the golden rule is to send encrypted format Emails.
