Explanation:
edg2021
direct quote from AV notes: "Analog technology transmits information using electric pulses. The human voice is the best example of analog communication. As the telephone was the major communication channel in the past, analog communication was common and the only type used.
Today, we depend on digital communication. Digital technology breaks down information into numerical bits and transmits the bits to digital receivers that decode the bits and recompose the original information. "

Assume that x and y are boolean variables and have been properly initialized.(x && y) || !(x && y) The result of evaluating the expression above is best described as (A) always true (B) always false (C) true only when x is true and y is true (D) true only when x and y have the same value (E) true only when x and y have different values
Answer:
(A) Always true
Explanation:
Given
Boolean variables x and y
Required
What is (x && y) || !(x && y)
Irrespective of what x or y is, the x && y is always true
Take for instance:
x = true;
y = true;
x&&y will also be true because the values of x and y were not altered
And this is true for whatever boolean value x or y assume
Having said that:
x&&y = true
So, the expression is analysed as follows:
(x && y) || !(x && y)
Substitute true for x&&y
(true) || !(true)
!(true) = false
So, the expression becomes:
true || false
|| represents the OR operator; and it returns true if at least one of the conditions is true.
By this:
true || false = true
Option (A) Always true answers the question.
A Flash Translation Layer translates user data to a format that can be written on the NVM. tracks which physical block contains the most number of consecutive invalid pages. tracks which physical block contains only valid pages. tracks which physical block contains only invalid pages.
Answer:
tracks which physical block contains only valid pages.
Explanation:
Flash translation layer or FTL is a system made up of software and hardware that manages solid-state drive or SSD operations. It implements data concurrency techniques like striping, interleaving, and pipelining to generate a high throughput. It also performs logical to physical addressing amongst other functionalities.
The FTL also tracks which physical block in the memory that contains only valid pages by performing a bad block management process, isolating and discarding the blocks with no valid pages
The Chief Information Officer (CIO) has determined the company’s new PKI will not use OCSP. The purpose of OCSP still needs to be addressed. Which of the following should be implanted?A. Build an online intermediate CA.B. Implement a key escrow.C. Implement stapling.D. Install a CRL.
Answer:
B. Implement a key escrow.
Explanation:
A key escrow can be defined as a data security method of storing very essential cryptographic keys.
Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.
As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.
Hence, the cryptographic keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).
In this scenario, the Chief Information Officer (CIO) has determined the company's new public key infrastructure (PKI) will not use online certificate status protocol (OCSP). However, the purpose of online certificate status protocol (OCSP) still needs to be addressed. Thus, what should be implemented is a key escrow because the online certificate status protocol (OCSP) is an internet protocol used for maintaining the security of a server and obtaining a digital certificate that has been revoked.

Fill in the blanks, so the print statement displays the result of the function call in order.
1 # This function compares two numbers and returns them
2 # in increasing order.
3 - def order_numbers(number1, number2):
4. if number2 > number1:
5 return numberi, number2
6 else:
7 return number2, number1
8
9 Run # 1) Fill in the blanks so the print statement displays the result # of the function call
10 ---, --- = order_numbers(100, 99) print(smaller, bigger)
Answer:
Rep;ace the blank with
smaller, bigger
So, the complete line is:
smaller,bigger=order_numbers(100,99)
Explanation:
From the question, we understand that the program is to return the order of a number from least to highest
This has been well implemented in order_numbers function
Because the order function returns two values, the order_function must be called in order to accept two values and the syntax is:
value1,value2 = function(return-value1,return-value2)
In this case, the statement is:
smaller,bigger=order_numbers(100,99)
So, in the next line of the main, the values of smaller and bigger are printed:
print(smaller,bigger)

A certain instructor assigns a 50-point problem and calculates an integer score 0-50 and assigns a letter grade according to the scale 40 - 50 is an A, 30 - 39 is a B, 20 - 29 is a C, 10 - 19 is a D and 0 - 9 is an F. Write a Python function called letter_grade which takes one argument, an integer, and RETURNS the appropriate letter grade.
Answer:
Following are the code to this question:
def letter_grade(x): #defining a method letter_grade that accepts one parameter
if x>=50 and x<=40:#defining if block that check value of x greater than 50 and less than 40
print("A")#print value
if x>=30 and x<=39:#defining if block that check value of x greater than 30 and less than 39
print("B")#print value
if x>=20 and x<=29:#defining if block that check value of x greater than 20 and less than 29
print("C")#print value
if x>=10 and x<=19:#defining if block that check value of x greater than 10 and less than 19
print("D")#print value
if x>=0 and x<=9:#defining if block that check value of x greater than 0 and less than 9
print("F")#print value
letter_grade(30) #calling the method letter_grade
Output:
B
Explanation:
In the above Python code, a method "letter_grade" is declared, that accepts an integer variable in its parameter, and defined the multiple if block to check the given value, which can be defined as follows:
In the first, if block, it checks the value of x greater than 50 and less than 40 , if the condition is true it will print the value "A".In the second, if block, it checks the value of x greater than 30 and less than 39, if the condition is true it will print the value "B".In the third, if block, it checks the value of x greater than 20 and less than 29, if the condition is true it will print the value "C". In the fourth, if block, it checks the value of x greater than 10 and less than 19, if the condition is true it will print the value "D".In the fifth, if block, it checks the value of x greater than 0 and less than 9, if the condition is true it will print the value "F".And at the last it call the method.

What is computer virus?
Answer:
A piece of code which is capable of copying itself and typically has a detrimental effect, such as corrupting the system or destroying data.
Explanation:
A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.
Simply, a computer virus is a harmful multiplying code that harms your computer and makes it slower, harder to use, and more vulnerable to other harmful unsafe software, apps, downloads and more.
How to get it?
You can get computer viruses just from going to unsafe websites downloading harmful files downloading harmful images downloading harmful videos clicking unsafe advertisementsand thats just a couple of examples, there's many many more but you get the idea.
Something that really sucks about computer viruses is that its hard to tell if something online is dangerous or not.
That's why people make specific softwares to protect your computer but even those can be unsafe or people could be trying to trick you.
Sometimes the computer will already have some sort of app or software to protect it from these harmful files, but make sure to pay attention when your on websites and check the urls and make sure it doesn't say anything along the lines of "unsafe" if it says that just simply exit the website and dont do anything further.
If your experiencing slowness, files you don't remember saving on your computer or extra files and apps that dont seem to belong, im sure there are places you can call online or in your local area to help with these issues.
Hope this helped!!

What sum will amounts to Rs 1227 in 9 months at 6%
e emple Interest 2.
Answer:
given us,
principal (p)= Rs 1227
Time(t)= 9
Rate(r)= 6./.
Here,
simple interest= P×T×R/100
= 1227×9×6/100
= 66258/100
= 662.58
Explanation:
by using simple interest formula
The principal investment required to get a total amount, principal plus interest, of Rs 227.00 from simple interest at a rate of 6% per year for 0.75 years (9 months) is $1,174.16
Given Data
Final Amount A = Rs 1227
Time = 9 months
Rate = 6%
Principal = ?
Equation:P = A / (1 + rt)
Calculation:First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Putting time into years for simplicity,
9 months / 12 months/year = 0.75 years
Solving our equation:
P = 1227 / ( 1 + (0.06 × 0.75)) = 1174.1626794258
P = $1,174.16

Explanation:
Divide a network 10.10.0.0 with subnet mask 255.255.0.0 into 62 subnets.
10.10.0.0
0000 1010. 0000 1010 . 0000 0000 . 0000 0000
255.255.0.0
1111 1111. 1111 1111 . 0000 0000 . 0000 0000
Required:
a. How many bits do we need to borrow from the host portion?
b. List the lowest and the highest IP address of the first usable subnet.
c. How many usable hosts are there in total before and after subnetting?
Answer:
A. 6 bits
B. lowest IP address is 10.10.0.1 and the highest IP address is 10.10.3.254
C. total number of usable hosts before subnetting = 65534
total number of usable hosts after subnetting = 65408
Explanation:
The IP address 10.10.0.0 with the subnet mask 255.255.0.0 is a class B address with 16 bits of the network address portion and 16 bits of the host portion.
To subnet the address to use 62 subnets (and to reduce the host IP address wasted) 6 bits are borrowed from the host portion of the address to give 2^6 = 64 subnets with two usable host addresses.
The first network address is 10.10.0.0 and the first usable host address of the subnet is 10.10.0.1 making it the lowest address, while the broadcast address is 10.10.3.255 and the address before it becomes the higher address in the network which is 10.10.3.254
The number of usable host of the network before subnetting is 2^16 -2 = 65534, while after subnetting is (2^(16-6) - 2) x 64 = 65408.

anyone have the Dell xps 13 laptop? if not pls don't answer but if you do, how is it going for you?
I do and it’s going alright; would recommend. Here’s what I think in bullet points.
- Good aesthetic design. Weave-like texture is nice and somewhat opulent.
- Good performance; you can overclock the i7 CPU.
- Battery life is at the upper end of the spectrum.
- No USB Type A Ports, big downside.
- Graphics are about 1000 points above industry average (3D Mark Fire Spark)
- Uses an SSD rather than a HDD; much quicker load time.
- I’d go for the $1,899 personally; it’s worth the extra money.
