Answer: The Atanasoff–Berry computer was the first automatic electronic digital computer. Limited by the technology of the day, and execution, the device has remained somewhat obscure. The ABC's priority is debated among historians of computer technology, because it was neither programmable, nor Turing-complete.
Explanation:
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.

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.

Which of the following characterizes pooled interdependence? Multiple Choice Each member has a great deal of discretion in terms of what they do and with whom they interact while collaborating to accomplish the team’s work. Interaction in the team only occurs between members who perform tasks that are next to each other in a sequence. Members interact with a subset of other members to complete the team’s work. Group members complete their work assignments independently, and then this work is simply "piled up" to represent the group’s output. Different tasks are done in a prescribed order, and the group is structured such that the members specialize in these tasks.
Answer:
Group members complete their work assignments independently, and then this work is simply "piled up" to represent the group’s output.
Explanation:
A pooled interdependence arise or occurs when the members of a group are able to function with relative independence and then their combined output or level of productivity is used to significantly augment the group's overall performance.
A characteristic of pooled interdependence is that group members complete their work assignments independently, and then this work is simply "piled up" to represent the group’s output.
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

very complex type of processing is carried out by a which computer
Answer:
hope it helps you
Explanation:
Processing is the “work” being done, in a program. For example, if a program added up a series of a million different numbers in a file, and computed a total, then the computer would be said to be “processing”, during the time where the numbers were being accumulated into a total.
Interestingly though, a computer is also processing “all the time”, that is even when it is at rest. That is because the operating system, (and underlying hardware), are still doing things which can be referred to as processing as well.
For example, the time-clock in a computer is continually updating regardless if there is any other processing going on in a system. This would be termed OS (operating system) level processing
