Answers
Answer:
1) Computers use voltages and since voltages changes often, no specific voltage is set for each number in the decimal system. For this reason, binary is measured as a two-state system i.e. on or off. Also, to keep calculations simple and convert into binary online, computers use the binary number system
2) 8 bits

Answers
Answer:
6 - crimp
1 - strip cable end
8 - test
2 - untwist wire ends
4 - trim wires to size
7 - check
3 - arrange wires
5 - attach connector
Explanation:
Step 1. Strip cable by inserting into the stripping tool. Rotate the cable in a smooth and even motion to create a clean cut and pull away towards the end of the wire to remove the sheathing.
Step 2. Untwist wire ends. Separate the twisted wires and straighten them out to easily sort in the right order.
Step 3. Arrange wires. Put the wires in the correct order so they can be properly crimped.
Step 4. Trim wires to size. Use the cutting section of the crimping tool to cut them into an even line.
Step 5. Attach connector. Insert the connector so that each of the small wires fits into the small grooves in the connector.
Step 6. Crimp. Insert the connector in the crimping tool. Squeeze the handles to crimp the connector and secure the wires.
Step 7. Check. Take the connector our of the tool and look at the pins to see that they're all pushed down.
Step 8. Test. Lightly tug at the connector to make sure it's attached to the cable.

Write a function that takes a word less than 25 characters long and returns the letter that word starts with (in capital letters)
Answers
The function that takes a word less than 25 characters long and returns the letter that word starts with in capital letters is as follows:
def first_letter(x):
if len(x) < 25:
for i in x:
return x[0].upper()
else:
return "Your text should be less than 25 characters"
print(first_letter("brainly"))
The code is written in python.
We declared a function named first_letter with the parameter x.
If the length of the word is less than 25 characters, we loop through it and return the first letter in uppercase.
Else if the word is not less than 25 character we ask the user to input a word less than 25 characters.
Finally, we call the function with a print statement.
The bolded portion of the code are python keywords.

Explanation:
because you can hack encrypted things well not so easily
Encryption is a secure website used to safeguard transmitted information. The correct option is C.
What is encryption?The process of converting information into a secret code that conceals its true meaning is known as encryption.
Cryptography is the study of information encryption and decryption. In the world of computers, ciphertext refers to encrypted data and plaintext to unencrypted data.
By converting the message's content into a code, encryption serves as a confidentiality tool. Integrity and authenticity are the goals of digital signatures.
They serve to confirm the message's source and show that the content hasn't been altered.
In the process of encryption, ordinary text, such as a text message or email, is scrambled into "cypher text," which is an unintelligible format. Secure websites utilise encryption to protect sent information.
Thus, the correct option is C.

However, there is a mistake: one of the numbers in the array is duplicated, which means another number is missing. Find and return the sum of the duplicated number and the missing number. Example: in the array [4, 3, 3, 1], 3 is present twice and 2 is missing, so 3 2

The program is an illustration of loops.
Loops are used to perform repetitive and iterative operations.
The program in Python where comments are used to explain each line is as follows:
#This intializes the list
nums = [5,4,4,2,1]
#This gets the length of the list
size = len(nums)
#This iterates through the list
for i in range(size):
#The following if condition determines the repeating number
if nums[abs(nums[i])-1] > 0:
nums[abs(nums[i])-1] = -nums[abs(nums[i])-1]
else:
repeating = abs(nums[i])
#The following if condition determines the missing number
if nums[i]>0:
missing = i + 1
#This calculates and prints the sum of the missing and the repeating numbers
