Write an expression that will print "in high school" if the value of user_grade is between 9 and 12 (inclusive). Sample output with input: 10 in high school
Answers
Answer:
Here is the expression:
user_grade = 10 #assigns 10 to the value of user_grade
if user_grade >=9 and user_grade <=12: #checks if the user_grade is between 9 and 12 inclusive
print('in high school') # prints in high school if above condition is true
else: #if user_grade is not between 9 and 12 inclusive
print('not in high school') # prints not in high school if user_grade is not between 9 and 12 inclusive
This can also be written as:
user_grade = 10 # assigns 10 to user_grade
if 9<=user_grade<=12: #if statement checks if user_grade is between 9 and 12 inclusive
print('in high school') #displays this message when above if condition is true
else: #when above if condition evaluates to false
print('not in high school')#displays this message
Explanation:
If you want to take the user_grade from user as input then:
user_grade = int(input("Enter user grade: "))
if user_grade >=9 and user_grade <=12:
print('in high school')
else:
print('not in high school')
The expression
if user_grade >=9 and user_grade <=12:
contains an if statement that checks a condition that can either evaluate to true or false. So the if condition above checks if the value of user_grade is between 9 and 12 inclusive.
Here the relational operator >= is used to determine that user_grade is greater than or equals to 9. relational operator <= is used to determine that user_grade is less than or equals to 12.
The logical operator and is used so both user_grade >=9 and user_grade <=12 should hold true for the if condition to evaluate to true. This means the user_grade should be between 9 and 12 (inclusive).
For example is user_grade = 10 then this condition evaluates to true as 10 is between 9 and 12 (inclusive). Hence the message: in high school is displayed on output screen.
But if user_grade= 13 then this condition evaluates to false because 13 is greater than 12. Hence the message: not in high school is displayed on output screen.
If user_grade = 8 then this condition evaluates to false because 8 is less than 9. Notice here that 8 is less than 12 so one part of the condition is true i.e. user_grade <=12 but we are using logical operator and so both the parts/expressions of the if condition should evaluate to true. This is why this condition evaluates to false. Hence the message: not in high school is displayed on output screen.
The screenshot of program and its output is attached.
Following are the program to the given question:
Program Explanation:
Include header file.Defining the main method.Defining an integer variable "user_grade" that inputs the value from the user-end.In the next step, a conditional statement is declared that checks the input value within "9 to 12", if the value is true it will use a print method that prints the user input value with a message.Otherwise, it will print the value with the message.Program:
#include <iostream>//header file
using namespace std;
int main()//main method
{
int user_grade;//defining integer variable user_grade
cin>>user_grade;//input user_grade value
if(user_grade>9 && user_grade<12)//defining if block that check input value is between 9 to 12
{
cout<<user_grade<<" in high school";//print value with message
}
else//else block
{
cout<<"not in high school";//print value with message
}
return 0;

The SQL WHERE clause: Limits the row data that are returned. Limits the column data that are returned. ALL Limits the column and row data that are returned.f the options
Answers
Answer: Limits the row data that are returned.
Explanation: In structured query language (SQL), The where clause is used as a filter. The filter is applied to a column and as such the filter value or criteria determines the values that are spared in the column on which the WHERE clause is applied. All rows in which the column value does not meet the WHERE clause criteria are exempted from the output. This will hence limit the number of rows which our command displays.
For instance,
FROM * SELECT table_name WHERE username = 'fichoh' ;
The command above filters the username column for username with fichoh, then displays only rows of Data with fichoh as the username. All data columns are displayed but rows of data which do not match fichoh are exempted.

C. Q is NP complete
D. Q is NP hard
Answers
Answer:
B. R is NP Hard
Explanation:
Given:
S is an NP complete problem
Q is not known to be in NP
R is not known to be in NP
Q is polynomial times reducible to S
S is polynomial times reducible to R
Solution:
NP complete problem has to be in both NP and NP-hard. A problem is NP hard if all problems in NP are polynomial time reducible to it.
Option B is correct because as given in the question S is an NP complete problem and S is polynomial times reducible to R.
Option A is not correct because R is not known to be in NP
Option C is not correct because Q is also not known to be in NP
Option D is not correct because Q because no NP-complete problem is polynomial time reducible to Q.

1.15) Many computers use one byte (8 bits) of data for each letter of the alphabet. There are 44 million words in the Encyclopedia Britannica. (a) What is the bit density (bits/in2) of the head of a pin if the entire Encyclopedia is printed on it
Answers
Answer: provided in the explanation section
Explanation:
the complete questions is given thus:
Many computers use one byte (8 bits) of data for each letter of the alphabet. There are 44 million words in the Encyclopedia Britannica.
(A). (What is the bit density (bits/in2) of the head of a pin if the entire encyclopedia is printed on it? Assume the average word is five letters long. (B). What is the byte density?
(C). What is the area of a single bit in nm2?
(D). A CD-ROM has a storage density of 46 megabytes/in2 and a DVD has a storage density of 329 megabytes/in2. Is the pinhead better or worse than these two storage media? How much better or worse?
ANSWER PROVIDED:
So both quest. a and b will be solved using the same principle.
Let us say we have the Head of the pin as (1/16)th of an inch in diameter.
Then the area is = pi*(1/(2*16))2 = pi*(1/32)2
Where each word is on an average 5 letters long, and there are 44 million words.
we have a total of 220000000 bytes.
220000000 bytes = 1.76 billion bits ( Since,1 Bytes=8 bits)
hence there are 1.76 billion bits total over the head of the pin.
Note that the bit density is bits per unit area;
since we know that now, let us proceed
Bit density = 1.76billion bits/(pi*(1/32)2 bits(inch)-2
approx 574 trillion bits per (inch)2
(b). Byte density tells us the measure of the quantity of information bytes that can be stored on a given length of track, area of surface, or even in a given volume of a computer storage medium.
⇒ Byte density is bit density divided by 8
(c). asked to find the area;
given that the inch2 = (2.54cm2) = (25.4e-6nm)2.
So to get the area,we will simply divide 574billion by (25.4e-6nm)2
(d). The pin head is WAY better.
what we mean is;
574 trillion bits per inch2 = around 75 trillion bytes per inch2
= 75 terabytes per inch2

Which of the following is true about the strategy that uses page fault frequency (PFF) to prevent thrashing?
A. A new process may be swapped in if PFF is too low.
B. A new page is allocated to a process if PFF is too high.
C. A page is deallocated from a process if the PFF is too low.
D. All of the above.
Answers
Answer:
The answer is "option B"
Explanation:
Thrashing arises whenever the virtual machine assets of a device are overused, leading to constant paging and page defect, that affects the processing of most programs.
In the given-question, only choice b is correct because this mechanism can be allocated to avoid the thumping of new pages if PFF is too high by increasing several frames or by removing expulsion frames.
Answer:
B. A new page is allocated to a process if PFF is too high.
Explanation:
Page fault frequency: In computer science, the term "page fault frequency" is also referred as PFF, and is described as a direct approach that is being utilized to handle thrashing and is considered as the one that tends to use "page-fault frequency concept". However, the problem that is connected with the "thrashing" is the "high-page fault rate" and therefore it is responsible for controlling the "page fault rate". However, if the "page-fault rate" is considerably too high, then it tends to indicate that the process consist of only few frames that is being allocated to it.
On the 80x86 CPU, the ESP register keeps track of the value on the top of the runtime stack.
a) true
b) false
Answers
Answer:
True
Explanation:
The ESP register acts as an indirect operand pointing to the top of the stack at any time.
Stack grows downwards from high memory when a program adds to the stack. However, when items are removed from the stack, it shrinks upwards from low to high memory.
The assembler reduces the stack pointer(ESP) register by 2, when a word value is pushed on to the stack. On the other hand, the assembler increases the stack pointer by 2 when a word value is popped off.
The assembler decreases or increases the ESP register by 4 when a double word value is pushed or popped off the stack respectively. Therefore the ESP register changes in multiples of 4.

In the given question some data is missing, that's why we define the answer as follows:
In the above code, a solution method is defined, which takes "s" variable as the parameter, and inside the method, an integer variable "x" is defined, that holds a value that is "0". In the next line, for loop is declared, that counts string value without space and inside the loop, if block is defined, that checks only the lowercase character and adds the value in x variable, and returns its value. Outside the method s variable is defined, that inputs the string value from the user end, and use the print method to call it and print its calculated value.The function returns a string of lowercase alphabets of length n, which is prescribed in the function. The function written in python 3 goes thus ;

#import the string and random modules
l_case = [x for x in string.ascii_letters if x.islower()]
#use list comprehension to take a list of lower case alphabets
def n_letters(n):
#initialize a function which takes a single parameter, number of letters

The so-called WAP gap involves the ______ of information where the two different networks meet, the WAP gateways.
Group of answer choices
A. integrity.
B. confidentiality.
C. authentication.
D. WTLS.
Answer:
B. confidentiality.
Explanation:
WAP is an acronym for wireless application protocol and it is a standard communications protocol used for accessing, formatting and filtering of data (informations) on wireless devices such as mobile phones over the internet or mobile wireless network.
Simply stated, a wireless application protocol (WAP) is a lightweight and easy to use protocol designed and developed for devices with low computing power e.g mobile devices.
There are two (2) main standard protocols that are being used for the wireless application protocol (WAP), these are;
1. Transport Layer Security (TLS).
2. Wireless Transport Layer Security (WTLS).
The so-called WAP gap involves the confidentiality of information where the two different networks (WTLS and TLS) meet, the WAP gateways.
In wireless communications, the wireless transport layer security was an improvement on the transport layer security. However, it created a major problem of confidentiality in the translation of the two protocols in a WAP architecture.
First, the user data is encrypted with a public key of an application server and then encrypted again from the client mobile device to the WAP gateway using the wireless transport layer security (WTLS) and lastly, the transport layer security (TLS) is used from the WAP gateway to the enterprise server. The TLS translates the WTLS data by decrypting it first and then encrypting it again.
The security concerns or confidentiality issues associated with using WAP is that, all messages are seen in plain text by the WAP gateways in the translation at the TLS point, thus causing the so called WAP gap.
