PLEASE EXPLAIN THE FOLLOWING OPERATING SYSTEMS QUESTION AND SOLUTION TO THE QUESTION IF IT IS THE RIGHT SOLUTION.


Consider an index-based file system with the inode containing 64 indexes, 1 indirect index pointing to a disk block containing an array of direct indexes, and 1 2-level index in the usual way. Assume that each index takes 4 bytes.

What is the maximum file size under this arrangement, if a disk block is 1024 bytes? Explain how do you compute this maximum size.

Solution:
An indirect block has 1024 bytes * 1 index/4 bytes = 256 pointers
So a file has at most 64 + 256 + 256*2 blocks and (64 + 256 * 256^2) * 1024 bytes.

How many disk accesses does it take to read one disk block at location 3000321 within a file, assuming no caching. Justify your answer.

Solution:
Block 3000321 is block number 2930, which means we have to read the inode, the 2-level index, a direct index, and the data block. 4 reads.

if (rowList.size() == 0) I click on column name and wait case will appear. When rowList.size() != 0 my test should go to  if (verifyRow(predicates, i)) { if true to this action in method,  }else if (!verifyRow(predicates, i)){ my method should click on selector 10 times and wait 10s after click and wait untill case will appear.

If case after clicking will appear then my test should do

List<WebElement> row = rowList.get(i);
                    WebElement cell = row.get(1);
                    action.doubleClick(cell).perform();
                    selectionResult.addMatchedRow(i);

this action.

For now I have error

You need to watch the 3-point bending test of plastic (PVC) beam and the 4- point bending test of mortar beam videos (Assignment folder, LMS). Also you need to use data file according to the student number and answer the questions below. (The data file will be emailed to you. Please contact us on course email if you believe you do not have the data file.) The data file has two sheets. If you use the wrong data file, the mark of 0 will be given for the assessment.

You must answer the questions in the assignment guide for each topic you have chosen (approximately 550 words) and explain and apply some aspect of that topic material to your life (or future life) (approximately 250 words). The submission for each topic should be no more than 800 words; for 2 topics the total word count for this assignment is therefore 1600 words. Do not exceed the word limit. Assignments will not be read nor assessed beyond the word limit. Word counts do NOT include the cover sheet/title page, title, or reference list.
Please clearly state your name, student identification number, and the chosen topics in your assignment. Please format your assignment using APA style guidelines (i.e., size 12 Times New Roman font, double-spaced) in a Word or PDF document and include a reference list using APA referencing style. An RMIT referencing guide is available here . 

Your written submission for each topic will be marked out of 20. With 2 topics, this assessment

- In this module the first assessment will involve you proposing a game design. The second assessment will
involve implementing that game with HTML/CSS/JavaScript.
This gameplay will be proposed by you and should not be based on one that already exists. The
implementation of the game should be approached using the concepts covered in class.
E.g. When designing your game bear in mind the limits of what you are able to do.
We will be covering the following in this module.
Repetition (functions, loops)
Storing complex data (Objects)
Storing Collections of data (Arrays)
Randomising, Sorting, & accessing data (arrays, sort functions, random
numbers)
Animating elements (via javascript and CSS)
Capturing Events (clicks, mouse movements, key presses etc.)
Changing graphics, text, CSS properties (DOM scripting)
etc.
There are several requ

Question 1
Technology has improved on agricultural business and as a result new smart agribusinesses are enhancing
agricultural value chain. Farmers are provided with marketing opportunities that help them link their products
with potential customers. Other agribusiness entrepreneurs are adding value to raw materials and selling new
products at competitive prices. There is the need to create an online trading platform for farmers to trade their
commodities at favourable prices or store them to receive warehouse receipts. The receipt system will give
farmers the opportunity to deposit goods (mainly grains) in order to acquire a warehouse; a financial
instrument that shows deposit proof with the quality and quality of the goods in question. Farmers can delay
the sale of their commodities to a period when prices are more favourable. Warehouse receipt systems can
therefore mobilize credit for agricultural sector and improve agriculture trade.

It is a GPS application to be implemented initially for only two users, features required:

1) show the real-time location of each user
2) place a marker at every point stopped at by each user and the path that was followed is shown

The application should provide a login screen and after having logged in the user can view all the online users as well. The login could be an email and a password

- Google maps and GPS required
- maybe Firebase database for the login
- please include comments as much as possible to help understand the code

Just need a simple initial implementation, nothing too fancy or complex

Create a stored procedure NEWGUESTBOOKING that adds a booking for a new guest.

The stored procedure NEWGUESTBOOKING receives the following parameters

Input Parameters
Guest name
Guest address
HotelNo
RoomNo
dateFrom
dateTo

Output Parameters
BookingNo int
BookingResult char(40)


The stored procedure
1.  Set autocommit = OFF;
2.  Issue the START TRANSACTION;
3.  Get the max guestNo in the database.
4.  Insert a new guest into the guest table using the max_guestno + 1, and the input parameters of the guest name.
5.  Check if the HotelNo is valid, if not rollback and exit. Code CONTINUE HANDLE Exception for NOT FOUND and set a HOTELINVALID FLAG ON.
6.  Check if the RoomNo  is valid, if not rollback and exit. Code CONTINUE HANDLE Exception for NOT FOUND and set a ROOMINVALID FLAG ON.
7.  Optionally, check if a booking already exist for the hotelno, roomno for the requested sta

3) be able to send a request of a meeting point and the other user can either accept or decline and if accepted then follows the way to that point
