Sports events, like the upcoming FIFA World Cup Qatar 2022 (Qatar 2022 World Cup), attract massive attention from every corner of the world. Just think, the last edition of the tournament in Russia was watched by a combined 3.57 billion viewers, equating to more than half of the global population aged four and over.
So, it is extremely important to take crucial steps for securing the data of the football fans who are going to make ticket reservation for FIFA World Cup Qatar 2022, as data required for reservation includes financial and personal information of the buyer.
Suppose you are a part of Qatar''''s best software team named "the Photon Intelligence Team" and you are required to set up a detailed alert system to secure the data of all the football fans who are coming to watch football matches.
Identify the programming paradigm from the list given below to collect user data for identification and authentication to allow them to come and watch football matches, make sure to keep in mind the data security while choosing the paradigm and justify your answer with proper reasons.

But there were questions over how it would work in reality, and fears over how the city would handle the supposed influx of more than a million visions once the tournament began.
Almost a week in, Doha seems to be coping well and while the $36 billion Metro system is handling a large load – Uber remains king for many Aussie travelers.
There were suggestions rides would be hard to come by, and traffic chaotic, once the tournament started but they are still readily available and cheap – even a half-hour trip out to one of the stadiums on the outskirts of the city can cost less than $A20.
Things can get tricky around the stadiums, where road closures can mean a bit of walking for drop-off and pick-ups but it’s still the easier option for many.

“We’ve been getting Ubers everywhere – we caught a Metro home from a game two nights ago and it took us an hour longer than it would have,” Warren Livingstone, founder of the Australian Fanatics said.
Michael Edgley, director of the Green and Gold Army, said it was a similar story for his travelling party of Socceroos families and fans, although some puzzling transport management was creating challenges for tour buses.
en quite as over-run as feared – perhaps as a result of less visitors than expected travelling.
“I was worried about restaurants and bars being overwhelmed but that doesn’t appear to be the case,” Edgley said.

FOOD & COST
The beers don’t come cheap, of course. A 500m Budweiser at the fan zone will set you back about $A21. The prices in hotels vary but some aren’t too bad – the cheapest pint I’ve found was around $A16 (research is a part of the job, you know).
Food prices aren’t outrageous but you’ll rack up a hefty bill by eating at the venues or hotel bars every night.
But there are bargains – and sensational meals – to be had for the more adventurous and curious with a sizable feed at a local neighbourhood Turkish restaurant, for instance, costing less than $A20.
Some Green and Gold army members were tipped off about a shawarma joint – inside a service station - by a local driver a few nights ago.
“And we had the best shawarma we’ve ever eaten in our lives for seven Qatari riyal ($A2.80),” Edgley said.
“You can eat out every night in expensive restaurants … but there is a migrant worker base here that is looking to do things cheaply and there are good solutions that are in place for that market. If you tap into them they can be quite interesting, fun and rewarding.”

There were startling images and reports of some of the conditions for fan accommodation but most Australian supporters, and media, have reportedly had fairly pleasant experiences.
Apartments are clean and a good size, albeit with some odd design flaws and defects that suggest things were finished off in a hurry. Think windows that go nowhere, fittings missing and appliances that either behave bizarrely, or don’t work at all — or far more dangerous problems.
“I’ve heard a few horror stories of people having to change accommodation but only a few,” Edgley said.
“I don’t think the building code (standard) is quite like it is in Australia,” Livingstone added.
sn’t seem to have that social interaction because the stadiums don’t really encourage that outside festival feeling,” he said.
“It’s not that festival of football that other World Cups have been because people get there early, they congregate outside and have a few beers.”
Edgley theorises it could be because crowds are made of travelling expats from around the region, rather than die-hard football fans.
“There’s not as many of what I would call the centre of the football community, who are very important in creating atmosphere in stadiums, who are extra committed,” he said.
“I don’t think there’s as many of those that we may have anticipated and I think that’s across the board with all of the countries.
“So the atmosphere feels not as fervent or dynamic as what we’ve experienced previously. It’s probably only by a little but it is noticeable. “

The paper must cite a minimum of two sources in APA format and be well-written. Check all content for grammar, spelling and be sure that you have properly cited all resources (in APA format) used.
Answer:
Explanation:
Virtual memory is a key component that plays an important role in the working of a computer. It is a technique that is used in an operating system to optimize the efficiency and speed of the system and also helps in providing space to store the data in the system. With the help of virtual memory, the computer system transfers data to other storage such as the RAM, hard drive, or solid-state disk.
Addressing is the technique that is used to assign the memory space or part to a file, program, or process. In the memory, each block has a unique address that is used to store data in the block. This address is used by the computer to store data in a block of memory. Whenever a variable is declared in a program, the computer assigns the block of memory to the variable using the stack or heap according to the user's request.
A stack is a type of Last in First out memory and it is used to store data that is required for function executions such as the return addresses, local variables, and formal parameters. The stack is used when allocating a fixed size of data but in case the size of the data is not fixed then in such cases the heap can be used for allocating dynamic-sized data. The stack and heap both are contiguous memory regions and they are placed side by side in the memory.
Virtual memory utilizes the computer hardware and software to assign the address to the files, programs, or processes that have access to the virtual memory. It copies the address of the files from the main memory and transfers these addresses to the RAM and hard disk to increase the speed of memory addressing. It helps in removing the free addresses of the unused files from the memory and thus increases the efficiency and speed of the system for memory addressing. It helps the system to swap files from the other storage to make optimal use of the RAM.
The main memory address which is also known as physical address is provided below-
The main memory consists of words which are further a collection of some n bits which is defined by the memory architecture.
In general,the whole memory consists of blocks which further consists of TAGs and SETs and then further word address identifies each word.
Hence the structure of memory is provided below-
Block Address Word Address

-The surplus will be divided in proportion to the patience of each player
Repeated Sequential Games. Multiple players participate in a sequential game, but they do not make decisions simultaneously. One player's choice influences the outcomes and choices of other players.
A sequential game in game theory is one in which one player decides their course of action before the other players do. In order to prevent the disparity in time from having an impact on strategy, the other players must be aware of the first player's decision. Decision trees are used to describe sequential games, which are controlled by the time axis. Combinatorial game theory can be used to quantitatively analyze sequential games with perfect information. Decision trees are a comprehensive kind of dynamic games that offer details on the various strategies that can be used to play a certain game. They display the order in which players take action as well as how frequently each player might choose. Decision trees also reveal the knowledge and ignorance of each player at the time they choose an action to take. Each player receives rewards at the decision nodes of the decision tree. In the early years of game theory, between 1910 and 1930, Neumann introduced and Kuhn further developed extensive form representations.
