Explanation:
Give a regular expression for binary numbers. They can be integers or binary fractions. A leading - sign is always allowed. Leading 0's are not allowed except when the integer part is 0. When the binary points is present, then neither the integer part nor the fractional part are allowed to be empty. If the integer part has more than 3 bits, then grouping with commas is required. Examples: Allowed: -0 1,111,010 -1,111.00 Not allowed: .11 1000 The 4-letter alphabet consists of 0, 1, dot, and comma.
Solution :
We have to provide an expression for the binary numbers. There can be binary fractions or integers. Whenever there is leading 0, it is not allowed unless the integer part is a 0.
Thus the expression is :
[tex]$(-+ \in )$[/tex] [tex]$[(1+10+11+100+101+110+111)(,000+,001+,010+,011+,111+,100+,101+,110)^*$[/tex] [tex]$(\in +.(0+1)^*(0+1))+(0.(0+1)^*(0+1))]$[/tex]
In this exercise we have to have knowledge about binary code to calculate with these numbers, so we have:
[tex](E+(0+1)*(0+1))[/tex]
What is a binary code?A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system.
Knowing this now we can perform the calculations like:
[tex](1+10+11+100+101+110+111)(000+001+010+011+111+100+101+110)\\(E+(0+1)*(0+1))[/tex]

Assume that the execution time for a program is directly proportional to instruction access time. The access to an instruction in the cache is 10 times faster than access to an instruction in the main memory. If an instruction is not found in the cache, i.e., cache miss, it is fetched from the main memory to the cache and then fetched from the cache to be executed. Assume that a requested instruction will cause cache miss has a probability of 0.08. Let the speedup factor is defined as the ratio of program execution time without the cache to program execution time with the cache.
a. Calculate the speedup factor to execute such a program.
b. using this assumption, assuming that the cache is 20 times faster than the main memory.
Answer:
a. 5.81
B. 7.93
Explanation:
A.
X is the time it takes to load instructions from cache
10X = time to execute program
0.08 = probability of cache instructions
1-0.08 = 0.92(92% instructions are going to be loaded from cache).
Tc = time to execute with cache
Tc = 0.92X+0.08x10X
= 0.92X+0.8X
= 1.72X
Speed factor = tm/tc
= 10X/1.72X
= 5.81
B.
If cache is 20 times faster
Tm = 20X
Tc = 0.92X + 0.08 x 20X
= 0.92X + 1.6X
= 2.52X
Speed factor = 20X/2.52X
= 7.93
Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them. The formula for computing the distance is: Square root of ((x2 - x1) squared + (y2 - y1) squared) Note that you can use pow(a, 0.5) to compute square root of a.
Answer:
x1 = input("enter x value of first number: ")
y1 = input("enter y value of first number: ")
x2 = input("enter x value of second number: ")
y2 = input("enter y value of second number: ")
ans = (float(x2)-float(x1))**2 + (float(y2)-float(y1))**2
ans = pow(ans, 0.5)
print(ans)

If a program has no syntax errors, can we assume that it is secure? Why or why not?
Answer:
We cannot say it is secure until it has gone through security testing.
Explanation:
Syntax errors are caused by errors that occur in the source code. Some of these errors are caused by spellings and punctuation. If the code does not follow the syntax of the programming language that it is being written, it would likely display a syntax error.
A program is secure only when it has gone through security testing and found to be protected from vulnerabilities and attacks.
Your goals as the IT architect and IT security specialist are to: Develop solutions to the issues that the specified location of IDI is facing. Develop plans to implement corporate-wide information access methods to ensure confidentiality, integrity, and availability. Assess risks and vulnerabilities with operating IT facilities in the disparate locations where IDI now functions and develop mitigation plans and implementation methods. Analyze the strengths and weaknesses in the current systems of IDI. Address remote user and Web site user’s secure access requirements. Develop a proposed budget for the project—consider hardware, software, upgrades/replacements, and consulting services. Prepare detailed network and configuration diagrams outlining the proposed change to be able to present it to the management. Develop and submit a comprehensive report addressing the learning objectives and your solutions to the issues within the scenario. Prepare a 10- to 15-slide PowerPoint presentation that addresses important access control, infrastructure, and management aspects from each location.

how can u spot fake news through camerawork, audio, and lighting? pls answer asap
Answer:
Fake news usually would involve heavy editing of the audio and visuals so that what people can see or hear will fit the lies being sold.
Explanation:
With respect to Videos, fake news would usually have very subtle and intelligent cuts and joints such that when pieced together, a speech for instance would contain only the words which fit the fake news. Also. the context would usually be omitted and you'd seldom find a whole unedited video supporting fake news.
With regards to the audio, authentic sources, in most cases, usually, start a recorded audio with their signature jingle. Fake news won't.
Pictures that have been doctored to suit fake news are usually characterized by their low quality, grainy and blurry feel.
It is important to point out, however, that with advances in technology, fake news' are begining to lose most of the qualities listed above.

4.16 LAB: Count characters Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. Ex: If the input is: n Monday the output is: 1 n Ex: If the input is: z Today is Monday the output is: 0 z's Ex: If the input is: n It's a sunny day the output is: 2 n's Case matters. Ex: If the input is: n Nobody the output is: 0 n's
Answer:
In Python:
sttr = input("String: ")
ch = input("Character: ")
count = sttr.count(ch)
print(str(count)+" "+ch, end = '')
if count>1 or count==0:
print("'s")
Explanation:
This prompts the user for string
sttr = input("String: ")
This prompts the user for character
ch = input("Character: ")
This counts the number of occurrence
count = sttr.count(ch)
This prints the number of occurrence of the character
print(str(count)+" "+ch, end = '')
This checks if the number of occurrence is 0 or greater than 1.
if count>1 or count==0:
If yes, it prints 's
print("'s")

I did this last year :/ i feel your pain.
Explanation:
Create a list called numbers containing the values from 1 through 15, then use slices to perform the following operations consecutively: a. Select number’s even integers. b. Replace the elements at indices 5 through 9 with 0s, then show the resulting list. c. Keep only the first five elements, then show the resulting list. d. Delete all the remaining elements by assigning to a slice. Show the resulting list.
Answer:
Kindly check explanation
Explanation:
From python :
List containing values from 1 through 15:
my_list = list(range(1,16))
#creates a list of values from 1 to 15,(16 is excluded)
B.) select even integers :
for digits in my_list :
if digit%2 == 0;
print(digit)
# prints numbers in the list which does not leave a remainder when divided by .
C.)
for digits in my_list[4,9]:
my_digit[digits] = 0
my_digits
#Replaces the elements at indices 5 through 9 with 0s, then show the resulting list.
D.)
my_digits[:5]
#selects digits with index 0 up to 4
E.)
del my_digits[:5]
#DELETE elements in my digits starting from the fifth index
write a paragraph in python to print 5 using a for loop
Answer:
For f in range(10):
if f == 5 :
print(f)
Explanation:
The for loop initiates a range of value and f is used to evaluate each value in the range.
The if statement block checks and detect if the number in the range, f is 5 ; once it detect that f equals to 5, it prints the digit 5 using the print statement.
