Answer: the new number overwrites the previous value at that memory location
Explanation:
When a number gets assigned to a variable that already has a value, the new number overwrites the previous value at that memory location. The correct option is A.
What is assigning value?To "assign" a variable is to symbolically link a specific piece of data to a name. Any operations performed on this "name" (or variable) must be true for all possible values.
The assignment operator is the equals sign, which should never be used for equality, and should never be followed by the double equals sign.
To assign a value to a variable, use the simple assignment operator. The assigned value is evaluated by the assignment operation.
It is possible to chain the assignment operator to assign a single value to multiple variables.
When a variable receives a new value, the previous value is overwritten.
Thus, the correct option is A.

My name is Yoshikage Kira. I'm 33 years old. My house is in the northeast section of Morioh, where all the villas are, and I am not married. I work as an employee for the Kame Yu department stores, and I get home every day by 8 PM at the latest. I don't smoke, but I occasionally drink. I'm in bed by 11 PM, and make sure I get eight hours of sleep, no matter what. After having a glass of warm milk and doing about twenty minutes of stretches before going to bed, I usually have no problems sleeping until morning. Just like a baby, I wake up without any fatigue or stress in the morning. I was told there were no issues at my last check-up. I'm trying to explain that I'm a person who wishes to live a very quiet life. I take care not to trouble myself with any enemies, like winning and losing, that would cause me to lose sleep at night. That is how I deal with society, and I know that is what brings me happiness. Although, if I were to fight I wouldn't lose to anyone.
4. Calculate the standard deviation for the following data set: Foundations of Technology Engineering byDesi OITEEA . . Data Set = 4, 14, 6, 2, 7, 12 217 ,
Answer:
[tex]\sigma_x = 5.68[/tex]
Explanation:
Given
[tex]x = 4, 14, 6, 2, 7, 12 2,17[/tex]
Required
The standard deviation
First, calculate the mean
[tex]\bar x =\frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{4+ 14+ 6+ 2+ 7+ 12 +2+17}{8}[/tex]
[tex]\bar x = \frac{64}{8}[/tex]
[tex]\bar x = 8[/tex]
The standard deviation is:
[tex]\sigma_x = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
So, we have:
[tex]\sigma_x = \sqrt{\frac{(4 - 8)^2+ (14 - 8)^2+ (6 - 8)^2+ (2 - 8)^2+ (7 - 8)^2+ (12 - 8)^2+ (2 - 8)^2+ (17 - 8)^2}{8-1}}[/tex]
[tex]\sigma_x = \sqrt{\frac{226}{7}}[/tex]
[tex]\sigma_x = \sqrt{32.2857}[/tex]
[tex]\sigma_x = 5.68[/tex]

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
Hence, a database management system (DBMS) is a system that enables an organization or business firm to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data.
Data administration is a strategic process that is typically responsible for establishing information policy, data planning, data dictionary development, and monitoring data usage in the firm.

Answer:
Use an encryption algorithm
Explanation:
An encryption algorithm can be used to hide the message from parties in-between or any third parties that might want to intercept the message being sent by Abudullah to Ahmed.
Encryption algorithms use cryptographic methods to encrypt or code data such that only the sender and receiver of that data have the keys to properly decode/decrypt these messages/data.

You are concerned that if a private key is lost, all documents encrypted using your private key will be inaccessible. Which service should you use to solve this problem
Answer:
Key escrow.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.
Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.
Hence, if a private key is lost, all documents encrypted using that private key will be inaccessible to the users. Thus, the service that can be used to solve this problem is a key escrow because the cryptographic (private) keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).
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.
I need help creating a symmetric histogram. The program should ask the user to enter the number of bars to print and the character to use to draw the bars. The count of characters in the bar needs to be displayed on the right-side of each bar. You must use a nested loop to display the output.
Answer:
The program in Python is as follows:
import math
bars = int(input("Bars: "))
symbol = input("Character: ")
current = 1
while current < bars * 2:
if current <= bars:
num = current
for i in range(num):
print(symbol,end="")
print(current)
else:
num = abs(bars * 2 - current);
for i in range(num):
print(symbol,end="")
print(i+1)
current+=1
Explanation:
This imports the math module
import math
This gets input for the number of bars
bars = int(input("Bars: "))
This gets input for the number of characters
symbol = input("Character: ")
This sets the current element to 1
current = 1
The following iteration is repeated until printing ends
while current < bars * 2:
The following checks for printing in ascending order
if current <= bars:
num = current
The following loop prints the characters in ascending order
for i in range(num):
print(symbol,end="")
This prints the number of characters
print(current)
The following checks for printing in descending order
else:
Calculate the number of iteration left
num = abs(bars * 2 - current);
The following loop prints the characters in descending order
for i in range(num):
print(symbol,end="")
This prints the number of characters
print(i+1)
current+=1
why the internet is not policed
Answer:
The Internet allows people to circumvent law by committing criminal acts from areas where their activities are not illegal. Those areas will always exist, and thus new regulations will be just as ineffective as the old ones are ["Net Needs Law Enforcement, Author Says,"]. But Internet traffic is marked with IP addresses, and those addresses can be tied to specific networks with specific locations. Shouldn't it be possible to separate traffic based on the originating network and treat data coming from relatively insecure locations differently than data coming from relatively secure locations? It would be much harder for someone in a rogue nation to hack a network if he had to hack an intermediary network first. And unlike government regulation, which has zero impact in areas where these threats are likely to originate, separating traffic by location might actually work
