Answer:
Swap codes in line 7 and 8
Explanation:
The code segment below
Line 1: count ← 0
Line 2: sum ← 0
Line 3: FOR EACH value IN numbers
Line 4: {
Line 5: count ← count + 1
Line 6: sum ← sum + value
Line 7: average ← sum / count
Line 8: }
Line 9: DISPLAY (average)
The above code will make the program translator calculate the average value at each iteration.
This will take a longer time to execute and also means more instructions for the program translator.
Swapping line 7 and 8 will reduce the number of instructions to execute. This will have an instant effect on the time taken to execute the program.
Swapping line 7 and 8 means that, the program translator will only calculate the average after it must have finished calculating the sum of the values in the iteration statement.

Government weapon in cold war
Answer:
See explaination for the program code
Explanation:
The Programming code:
inFile = open("stuff.txt", "r")
num = []
Sum = 0
for val in inFile.readlines():
value = val.split(",")
Sum = Sum + int(value[1])
print("Sum of second number on every line in the file is: ", Sum)
inFile.close()

Answer:
The answer is by using a covert channel like shared memory objects such as files, directories,messages, etc since both the user and the sender of the document are on same network of the company.
Explanation:
The Bell LaPadula MultiLevel Security model was a security policy developed by Bell and LaPadula in 1973 in response to a security issue raised by the US Air Force regarding file-sharing mainframe computers . Actually, many people with networked systems have realized by early 1970s that the protection purportedly offered by many commercial operating systems was poor, and wa not getting better any time soon. This was observed when it was noticed that as one operating system error was fixed, some other vulnerability would be discovered. There was also the constant worry that various unskilled users would discover loopholes in the operating system during usage and use them to their own advantage.
Information release may take place via shared memory objects such as files, directories, messages, and so on. Thus, a Trojan Horse acting on behalf of a user could release user-private information using legitimate operating system requests. Although developers can build various mechanisms within an operating system to restrict the activity of programs (and Trojan Horses) operating on behalf of a user , there is no general way, short of implementing nondiscretionary policy models, to restrict the activity of such programs. Thus, given that discretionary models cannot prevent the release of sensitive information through legitimate program activity, it is not meaningful to consider how these programs might release information illicitly by using covert channels.
For example, for someone with higher integrity level (SECRET) to send an accounts payable application to a user, if the untrusted accounts payable application contains a Trojan Horse, the Trojan Horse program could send a (legal) message to the said user process running at a lower integrity level (CONFIDENTIAL), thereby initiating the use of a covert channel. In this covert channel, the Trojan Horse is the receiver of (illegal) lower integrity-level input and the user process is the sender of this input.
