Answer: When computer and communication technologies are combined the result is Information technology.
Explanation: This is a technology that combines computation with high-speed data, sound, and video transmission lines. All computer-based information systems utilized by companies, as well as their underlying technologies, are referred to as information technology.
As a result, information technology encompasses hardware, software, databases, networks, and other electronic gadgets.
IT refers to the technological component of information systems, making it a subsystem of information systems.
Information systems, users, and administration would all be included in a broader definition of IT.
Many organizations rely on IT to support their operations, since IT has evolved into the world's primary facilitator of project activities. IT is sometimes utilized as a catalyst for fundamental changes in an organization's structure, operations, and management. This is because of the capabilities it provides for achieving corporate goals.
These competences help to achieve the following five business goals:
Increasing productivity,
lowering expenses,
improving decision-making,
improving customer interactions, and
creating new strategic applications.
Memory Management - Page fault and Page Thrashing
i) What is page fault?
ii) Describe the steps that take place after a page fault. Include both the actions taken within the handler and those that are taken in hardware before the handler is initiated. How segment defects might be found and treated should be mentioned in your response. Including diagrams may make it easier for you.
iii) What is page thrashing and how might it be avoided?
1) A page fault is an exception raised by the memory management unit when a process accesses a memory page without making the necessary preparations. To access the page, a mapping must be added to the process's virtual address space.
2) Once the virtual address that produced the page fault is determined, the system verifies that the address is genuine and that there is no protection access problem. If the virtual address is legitimate, the system determines if a page frame is available. If no frames are available, the page replacement procedure is used to delete a page.
3) Thrashing occurs when the page fault and switching occur at a higher frequency, requiring the operating system to spend more time exchanging these pages. This is referred to as thrashing in the operating system. The CPU utilization will be lowered or nonexistent as a result of thrashing.
Eliminating one or more running programs is a temporary remedy for thrashing. Adding extra RAM to the main memory is one of the recommended strategies to minimize thrashing. Another option for dealing with thrashing is to increase the size of the swap file.
What is Memory Management?Memory management is a type of resource management that is used to manage computer memory. Memory management must include mechanisms for dynamically allocating parts of memory to programs at their request and freeing it for reuse when no longer required.
Management is the method of regulating and coordinating computer memory by allocating parts known as blocks to various operating applications in order to maximize system performance. The primary memory management function of an operating system is the most critical.

What are progression mechanics? Why are they important for games?
The phrase "progression mechanics" in game design refers to video game mechanics where the creator establishes a path of action that a player must follow to advance in the game. The checkpoints that a character must achieve to move on to the next level are crucial to the progression of gameplay. The checkpoints change depending on the type of game. A few standard checkpoints are:
In action, adventure, and role-playing games, defeating the level boss (RPGs)achieving the third place on a certain track in racing gamescompleting a set of puzzles in a game of puzzlestaking down the enemy's base of operations in real-time strategy gamesMost video games are developed using a progression gameplay concept. Designers like progression gaming because it enables them to build a compelling narrative around the game's action. Every game aims to be both engaging and enjoyable to play. Proponents of progression gameplay point out that because game creators are aware of the direction their creation will go in, they can create a far richer and more complex narrative around that direction.
On the other hand, proponents of emergent gameplay prefer games where player random acts have an unlimited number of potential results rather than a finite set of predetermined outcomes that are mapped out by designers. Of course, there is a lot of room for compromise between the two methods. Both emergent gameplay and progression are features found in many games.

A manufacturer wants to keep track of the average of the ratings that have been submitted for an item using a running average. The algorithm for calculating a running average differs from the standard algorithm for calculating an average, as described in part (a).
A partial declaration of the RunningAverage class is shown below. You will write two methods of the RunningAverage class.
*
public class RunningAverage
{
}
/** The number of ratings included in the running average. private int count;
/** The average of the ratings that have been entered. */ private double average;
// There are no other instance variables.
/** Creates a RunningAverage object.
* Postcondition: count is initialized to 0 and average is
* initialized to 0.0.
*/
public RunningAverage()
{ /* implementation not shown */ }
/** Updates the running average to reflect the entry of a new
* rating, as described in part (a).
*/
public void updateAverage (double newVal)
{ /* to be implemented in part (a) */ }
/** Processes num new ratings by considering them for inclusion
* in the running average and updating the running average as
necessary. Returns an integer that represents the number of
*
* invalid ratings, as described in part (b).
* Precondition: num > 0
*/
public int processNewRatings (int num)
{ /* to be implemented in part (b) */ }
/** Returns a single numeric rating.
public double getNewRating()
{ /* implementation not shown */ }
(a) Write the method updateAverage, which updates the RunningAverage object to include a new rating. To update a running average, add the new rating to a calculated total, which is the number of ratings times the current running average. Divide the new total by the incremented count to obtain the new running
average.
For example, if there are 4 ratings with a current running average of 3.5, the calculated total is 4 times 3.5, or 14.0. When a fifth rating with a value of 6.0 is included, the new total becomes 20.0. The new running average is 20.0 divided by 5, or 4.0.
Complete method updateAverage.
/** Updates the running average to reflect the entry of a new
* rating, as described in part (a).
*/
public void updateAverage (double newVal)
(b) Write the processNewRatings method, which considers num new ratings for inclusion in the running average. A helper method, getNewRating, which returns a single rating, has been provided for you.
The running average must only be updated with ratings that are greater than or equal to zero. Ratings that are less than 0 are considered invalid and are not included in the running average.
The processNewRatings method returns the number of invalid ratings. See the table below for three examples of how calls to process NewRatings should work.

Create two parallel arrays that represent a standard deck of 52 playing cards. One array is numeric and holds the values 1 through 13 (representing Ace, 2 through 10, Jack, Queen, and King). The other array is a string array that holds suits (Clubs, Diamonds, Hearts, and Spades).
Create the arrays so that all 52 cards are represented. Then, create a War card game that randomly selects two cards (one for the
player and one for the computer) and declares a winner or a tie based on the numeric value of the two cards. The game should last for 26 rounds and use a full deck with no repeated cards. For this game, assume that the lowest card is the Ace.
Display the values of the player’s and computer’s cards, compare their values, and determine the winner. When all the cards in the deck are exhausted, display a count of the number of times the player wins, the number of times the computer
wins, and the number of ties.
hints:
1) Start by creating an array of all 52 playing cards.
2) Select a random number for the deck position of the player’s first card and assign the card at that array position to the player.
3) Move every higher-positioned card in the deck “down” one to fill in the gap. In other words, if the player’s first random number is 49, select the card at position 49 (both the numeric value and the string), move the card that was in position 50 to position 49, and move the card that was in position 51 to position 50. Only 51 cards remain in the deck after the player’s first card is dealt, so the available-card array is smaller by one. In the same way, randomly select a card for the computer and “remove” the card from the deck.
Using the knowledge in computational language in python it is possible to write a code that Create the arrays so that all 52 cards are represented.
