Two-phase commit protocol:
The two-phase commit protocol is used to make sure that the transaction atomicity and
The need of this protocol helps to make sure that the database changes form remote site is coincided. If not, each and every transaction is undone to sustain a consistent database.
There are two phases in two-phase commit protocol. They are,
- Preparation
- The final COMMIT
Phase 1: Preparation
- The coordinator transfers the message from PREPARE TO COMMIT to all subordinates...

I need to render an image of a car continuously for a smooth visual experience in C# WinForms. It gets the location array (that has all the x,y of the tiles it should visit) from another function - assume it is already written.
write c program with features:
Register a Bunny: Store the bunny's name, poem, and initialize the egg count to 0.
Modify an Entry: Change the bunny's poem or update the egg count.
Delete a Bunny: Remove a registered bunny from the list.
List All Bunnies: Display all registered bunnies and their details.
Save & Load Data: Store bunny data in a file to persist between runs.
Use a struct to represent a bunny contestant.
Store data in a binary file (bunnies.dat) for persistence.
Use file I/O functions (fopen, fwrite, fread, etc.) to manage data.
Implement a menu-driven interface for user interaction.
Help, how do I write the pseudocode for the findMean function and flowchart for this?

- Lab 07: Java Graphics (Bonus lab) In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: ➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). о The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: о An input button to register your mouse to the drawing panel. ○ о о A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels.…arrow_forwardIf a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A.

(b) Find out what an application has to do, on the operating system of your choice, to receive such messages. (c) Why might it not be a good idea to send such messages directly back to the originating port P on A?arrow_forwardDiscuss how business intelligence and data visualization work together to help decision-makers and data users.
