In the code snippet below, pick which instructions will have pipeline bubbles between them due to hazards.
a. lw $t5, 0($t0)
b. lw $t4, 4($t0)
c. add $t3, $t5, $t4
d. sw $t3, 12($t0)
e. lw $t2, 8($t0)
f. add $t1, $t5, $t2
g. sw $t1, 16($t0)
Answer:
b. lw $t4, 4($t0)
c. add $t3, $t5, $t4
Explanation:
Pipeline hazard prevents other instruction from execution while one instruction is already in process. There is pipeline bubbles through which there is break in the structural hazard which preclude data. It helps to stop fetching any new instruction during clock cycle.

Explanation:
a user called to inform you that the laptop she purchased yesterday is malfunctioning and will not connect to her wireless network. You personally checked to verify that the wireless worked properly before the user left your office. the user states she rebooted the computer several times but the problems still persists. Which of the following is the first step you should take to assist the user in resolving this issue?
This project must target a Unix platform and execute properly on our CS1 server.
The project must be written in C, C++, or Java.
Problem Overview
This project will simulate a scheduler scheduling a set of jobs.
The project will allow the user to choose a scheduling algorithm from among the six presented in the textbook. It will output a representation of how the jobs are executed.
Design
You may design your own implementation approach, but here are a few constraints.
Your program should read in a list of jobs from a tab-delimited text file named jobs.txt. The format of the text file should have one line for each job, where each line has a job name, a start time and a duration. The job name must be a letter from A-Z. The first job should be named A, and the remaining jobs should be named sequentially following the alphabet, so if there are five jobs, they are named A-E. The arrival times of these jobs should be in order.
The scheduler choice should be a command-line parameter that is one of the following: FCFS, RR, SPN, SRT, HRRN, FB, ALL. If ALL is input, the program should produce output for all six scheduling algorithms. RR and FB should use a quantum of one. FB should use three queues.
Your output should be a graph as shown in the slides. The graph can be text or you can use a graphics package such as JavaFX to draw the graph. For text, you may draw the graph down the page rather than across.
Your program should be able to reproduce the sample shown in the book as well as any similar set of jobs.
Sample Output
Below is sample text-based output. For graphical output, you can make the graph look like the ones in the textbook and slides.
FCFS
A XXX
B XXXXXX
C XXXX
D XXXXX
E XX

Which of the following is not an advantage of e-commerce for consumers?
a. You can choose goods from any vendor in the world.
b. You can shop no matter your location, time of day, or conditions.
c. You have little risk of having your credit card number intercepted.
d. You save time by visiting websites instead of stores.
Answer: c. You have little risk of having your credit card number intercepted.
====================================
Explanation:
Choice A is false because it is an advantage to be able to choose goods from any vendor from anywhere in the world. The more competition, the better the outcome for the consumer.
Choice B can also be ruled out since that's also an advantage for the consumer. You don't have to worry about shop closure and that kind of time pressure is non-existent with online shops.
Choice D is also a non-answer because shopping online is faster than shopping in a brick-and-mortar store.
The only thing left is choice C. There is a risk a person's credit card could be intercepted or stolen. This usually would occur if the online shop isn't using a secure method of transmitting the credit card info, or their servers are insecure when they store the data. If strong encryption is applied, then this risk can be significantly reduced if not eliminated entirely.
Answer:
c. You have little risk of having your credit card number intercepted.

Code a complete Java program to load and process a 1-dimensional array.
Create clear comments as you code to tell me what you are doing.
Import the Java libraries that you will need.
Create a single dimensional array that will hold 15 wages.
In the main, load an array with all of the records from a .txt file named Salary txt. The file has 15 records in it.
Sort the array in ascending order.
Write a method named increaseWages(). This method will add $500 to each of the 15 wages. In other words, you are giving each person a raise of $500.
Pass the array to the method from the main().
Increase the wage amounts in the array (as described above), in the method. In other words, in the end the array should hold the NEW, higher wages.
Output each new wage (use the console for this)
Calculate a total of the new wages in the method
Output the total of the new wages in the method (use a dialog box for this)
Return the array with the new wages to the main().
There is NO user interaction in this program.

while(sc.hasNext()){
String data=sc.nextLine();//reads a wage as a string
String w=data.substring(1);//remove the dollar from the string data

Suppose a TCP segment is sent while encapsulated in an IPv4 datagram. When the destination host gets it, how does the host know that it should pass the segment (i.e. the payload of the datagram) to TCP rather than to UDP or some other upper-layer protocol
Answer and Explanation:
A host needs some datagram where TCP is encapsulated in the datagram and contains the field called a protocol. The size for the field is 8-bit.
The protocol identifies the IP of the destination where the TCP segment is encapsulated in a datagram.
The protocol field is 6 where the datagram sends through TCP and 17 where the datagram is sent through the UDP as well
Protocol with field 1 is sent through IGMP.
The packet is basic information that is transferred across the network and sends or receives the host address with the data to transfer. The packet TCP/IP adds or removes the field from the header as well.
TCP is called connection-oriented protocol as it delivers the data to the host and shows TCL receives the stream from the login command. TCP divides the data from the application layer and contains sender and recipient port for order information and known as a checksum. The TCP protocol uses the checksum data to determine that data transferred without error.

Write a function process_spec that takes a dictionary (cmap), a list (spec) and a Boolean variable (Button A) as arguments and returns False: if the spec has a color that is not defined in the cmap or if Button A was pressed to stop the animation Otherwise return True
Answer:
Explanation:
The following code is written in Python. The function takes in the three arguments and first goes through an if statement to check if Button A was pressed, if it was it returns False otherwise passes. Then it creates a for loop to cycle through the list spec and checks to see if each value is in the dictionary cmap. If any value is not in the dictionary then it returns False, otherwise, it returns True for the entire function.
def process_spec(cmap, spec, buttonA):
if buttonA == True:
return False
for color in spec:
if color not in cmap:
return False
return True
The percentage of the audience with TV sets turned on that is watching a particular program is known as the ____________________.
Answer:
Share.
Explanation:
Social media publishing also known as broadcasting, can be defined as a service that avails end users the ability to create or upload web contents in either textual, audio or video format in order to make them appealing to a target audience.
Thus, these multimedia contents are generally accessed by end users from time to time through the use of various network-based devices and television set. As users access these contents, they're presented with the option of sharing a particular content with several other people a number of times without any form of limitation.
Additionally, the demographic or amount of audience (viewers) that a television show or program is able to get to watch at a specific period of time is generally referred to as share.
Hence, the percentage of the audience with TV sets turned on that is watching a particular program is known as the share.
For example, the percentage of the audience tuned in to watch a champions league final on a Saturday night, 8:00pm via their television set.
