Answer:
Explanation:
RegWrite:
• All R-type instructions, lw and addi:
• The result of the operation/load/addition would not be written back to the destination register
• ALUOP
• The following R-type instructions: add, sub, and, or, slt
• With ALUOp stuck at 0, the ALU decoder would interpret all those instructions as either add or subtract operations. The ALUOp gets decoded to add or subtract depending on ALUOp[0].
• MemWrite:
• Only sw is affected.
• The memory write won’t take place.
What is the advantage of using a translation look-aside buffer (TLB), also called associative memory, in the logical-physical address mapping process? Explain how the logical-physical address mapping logic works using an inverted page table. When does the MMU detect page-fault? Explain four of the main steps for resolving page faults.
Answer:
A) The advantage of using TLB is that it is used for storing the recent transactions of the virtual memory to the physical memory and this is used for the sole purpose of fast retrieval of data
B) When using an inverted table the logical-physical address mapping logic works as a hashing function by connecting pieces of the hardware of logical address and getting them translated to the physical address. this hash function in turn generates the index to the frame table
C) The MMU detect page-fault when there is an exception been raised by the computer when a program is ran to access a memory page and this program is not mapped out by the MMU in the process
The four steps are :
The first step is to check on the memory address requested to make sure of a valid memory request.
The second step is to setup A free frame and a disk operation that is scheduled for getting the necessary page from the disk.
As the the I/O is been completed the processor table is been updated
Finally the Instruction will get restarted from the beginning indicating what might have been caused by a page fault.

wordList is a list of words that currently contains the values ["tree", "rock", "air"]
Which of the following lines will result in the list containing the values ["air", "rock", "air"]
A. wordList[0] = wordList[2]
B. wordList[2] = wordList[O]
C.insertitem(wordList, O, "air")
D. removeltem(wordList,0)
Answer:
A. wordList[0] = wordList[2]
Explanation:
Required
Which line would give ["air", "rock", "air"]
From the question, we have that:
wordList = ["tree", "rock", "air"]
which means that:
wordList[0] = "tree"
wordList[1] = "rock"
wordList[2] = "air"
Analyzing the options.
A. wordList[0] = wordList[2]
This will assign the item in wordList[2] to wordList[0].
and the result would be
So:
wordList[0] = "tree"
would change to
wordList[0] = "air"
The new content of wordList would then be ["air", "rock", "air"]
Option (A) answers the question
The list variable wordList contains three string values, Hence, to obtain the list, ["air", "rock", "air"], the lines wordList[0] = wordList[2] would be used.
List values are indexed from 0 ; hence, tree = index 0 ; rock = index 1 ; air = index 2 To assign the the string "tree" to index 0, then wordList[2] is assigned to wordList[0].wordList[0] is now "air"Hence, the required line of code would be wordList[0] = wordList[2]

A user creates a GPO. What do you need to do for that user to manage his or her GPO that he or she created?
Answer: Nothing should be done.
Explanation:
Group Policy helps in the provision of a centralized management of operating systems, and applications. It should be noted that a group policy object (GPO) is simply referred to as the configurations involving the group policy.
Nothing should be done to manage the GPO created. When the permission to create a GPO has been given to someone, it means that they can also manage the GPO therefore, nothing needs to be done anymore.

In the Allow list box in the Data Validation dialog box,the _____ option means that the cell will accept only times.A) ChronologyB) ClockC) TimeD) Calendar
Answer:
C) Time
Explanation:
Given that Data validation is a feature in Microsoft Excel in which a user used to specify or determines the type of value or characters that can be typed or entered into a cell.
For example, using data validation to ensure a value of a number is whole numbers, or to ensure character entry is less than 25 characters.
Hence, in this case, the correct answer is the TIME option, will only result in cell accepting only times.

A new version of your operating system is released with several changes made to the transport layer protocols. Specifically, TCP has been removed completely but UDP was not changed. What specific changes must be made to your application to accomodate these changes?
Answer:
Throughout the description section down, the overview and per the instance.
Explanation:
Throughout terms of communicating and maintaining a link between the application as well as the network, TCP protocols were essential. The program would not be linked or activated if the TCP has indeed been fully disabled. The essential TCP protocol that enables the application to be linked from over network become HTTP as well as HTTPS. Almost all of the significant protocols needed to operate some programs are based primarily on TCP protocols. Besides, as SSH would not operate as a TCP protocol, the OS would not be remotely linked.Therefore, that would also make it impossible for all the administrators to operate upon this system.
Consider a distributed denial of service (DDOS) attack, Assume the attacker has compromised a number of broadband connected computers to use as zombie systems. If the ISP provides a maximum uplink data rate of 512 Kbps in ADSL, what is the maximum number of 512-byte ICMP echo request (ping) packets a single zombie computer can send per second? How many such zombie systems would the attacker need to flood a target server in an organization that has
a. A Fast Ethernet.
b. A Gigabit Ethernet.
Answer:
A ) 200 Zombie systems
B ) 200 Zombie systems
Explanation:
maximum uplink data rate : 512 kbps = 512 * 1000 * 8 = 4096000 bits/sec
Determine the number of 512 byte ICMP echo packets = 512 * 8 = 4096 bits
hence the maximum number of 512-byte ICMP echo request (ping) packets a single zombie computer can send per second = 400 packets/sec
i.e. for 512kbps = 400 packets/sec
Determine the number of Zombie systems that the attacker will need to flood a target server
A) For a fast ethernet
A fast ethernet = 100 mbps
The number of Zombie systems needed = 1 zombie system * 200
and 1 zombie system = 512 kbps
therefore for a Fast ethernet the number of zombies systems needed = 200
B) For A Gigabit Ethernet
same as a fast ethernet system i.e. = 200

Explain why the expected value of an F ratio is 1.00 when the null hypothesis is true if there is no treatment effect the numerator.
Answer:
The reason is that the f ratio is balanced due to the numerator and denominator having equal sources of variability.
Explanation:
The expected value of an F ratio is 1.00 when the null hypothesis is true because in a scenario where there is no treatment effect, we have both the numerator and the denominator of the F ratio both measuring equal sources of variability.
Whenever this happens then the F ratio will be balanced and also it will have a value that is near 1.00.

If process P0 is switched to process P1, state for P0 will be saved into ____, and state from ___ will be reloaded.
Answer:
1. PCB0
2. PCB1
Explanation:
Given that PCB is often referred to as Process Control Block, is a form of data structure that is applicable and utilized by the computer operating systems to store all the information concerning a process.
This process is carried out in a way that when Process P0 is initialized, the operating system established a related process that takes the computer processing unit from Process P0 and allocates it to Process P1, the Operating System, in turn, will save P0's PCB, and then reload P1's PCB.
Hence, If process P0 is switched to process P1, the state for P0 will be saved into "PCB0" and the state from "PCB1" will be reloaded.

Armstrong Numbers Programming challenge description: An Armstrong number is an n-digit number that is equal to the sum of the nth powers of its digits. Determine if the input numbers are Armstrong numbers. Input: Your program should read lines from standard input. Each line has a positive integer. Output: Print out True if the number is an Armstrong number, or False if not. Test 1 Test Input 351 Expected Output False
Answer:
Written in Python
number = int(input("Enter a number: "))
computesum = 0
lent = len(str(number))
for digit in str(number):
computesum += int(digit)**lent
if number == computesum:
print("true")
else:
print("false")
Explanation:
This line prompts user for Input input
number = int(input("Enter a number: "))
This line initialises the sum of the nth power of the digits to 0
computesum = 0
This line gets the length of input (i.e. number of digits)
lent = len(str(number))
The following iteration iterates through the digit to check for Armstrong numbers
for digit in str(number):
computesum += int(digit)**lent
This checks if the input number equals the computed sum
if number == computesum:
print("true") --- if yes, "true" is printed
else:
print("false") --- if otherwise, "false" is printed

A server process in Host B has a welcoming socket at port 977. What will trigger the server process to create a connection socket?
Answer:
Explanation:
This connection socket will be created when Host B receives a TCP SYN segment that contains the destination port number 977. This means that there is data that is trying to enter through that port number, as a welcoming socket this destination is available and when data requests access through it the OS creates a connection socket using Host B in order to allow access to the TCP SYN segment.
