Please use thread to complete the following program: one process opens a file data.txt, then creates a thread my_thread. The job of the thread my_thread is to count how many lines exist in the file data.txt, and return the number of lines to the calling process. The process then prints this number to the screen.
Basically, you need to implement main_process.c and thread_function.c.
Basic structure of main_process.c:
int main ()
{
Open the file data.txt and obtain the file handler fh;
Create a thread my_thread using pthread_create; pass fh to my_thread;
Wait until my_thread terminates, using pthread_join;
Print out how many lines exist in data.txt.}
Basic structure of thread_function.c:
void *count_lines(void *arg)
{
Obtain fh from arg;
Count how many lines num_lines exist in fh;
Close fh;
Return num_lines
}
Answer:
Here is the code:-
//include the required header files
#include<stdio.h>
#include<pthread.h>
// method protocol definition
void *count_lines(void *arg);
int main()
{
// Create a thread handler
pthread_t my_thread;
// Create a file handler
FILE *fh;
// declare the variable
int *linecnt;
// open the data file
fh=fopen("data.txt","r");
// Create a thread using pthread_create; pass fh to my_thread;
pthread_create(&my_thread, NULL, count_lines, (void*)fh);
//Use pthread_join to terminate the thread my_thread
pthread_join( my_thread, (void**)&linecnt );
// print the number of lines
printf("\nNumber of lines in the given file: %d \n\n", linecnt);
return (0);
}
// Method to count the number of lines
void *count_lines(void *arg)
{
// variable declaration and initialization
int linecnt=-1;
char TTline[1600];
//code to count the number of lines
while(!feof(arg))
{
fgets(TTline,1600,arg);
linecnt++;
}
pthread_exit((void *)linecnt);
// close the file handler
fclose(arg);
}

5. Distributed Systems and Networks:
6. Security: Security is a must-have for the client. Explain how to protect user information on and between various platforms. Consider the user protection and security capabilities of the recommended operating platform.>
Answer:
Here the answer is given as follows,
Explanation:
Operating Platform:-
In terms of platforms, there are differences between, mobile games and pc games within the way it's used, the operator, the most event play, the sport design, and even the way the sport work. we all know that each one the games on console platforms, PC and mobile, have their own characteristic which has advantages and disadvantages All platforms compete to win the rating for the sake of their platform continuity.
Operating system architectures:-
Arm: not powerful compared to x86 has many limitations maximum possibility on arm arch is mobile gaming.
X86: very powerful, huge development so easy to develop games on platforms like unity and unreal, huge hardware compatibility and support
Storage management:-
On the storage side, we've few choices where HDD is slow and too old even a replacement console using SSD. so SSD is the suggested choice. But wait SSD have also many options like SATA and nvme.
Memory management:-
As recommended windows, Each process on 32-bit Microsoft Windows has its own virtual address space that permits addressing up to 4 gigabytes of memory. Each process on 64-bit Windows features a virtual address space of 8 terabytes. All threads of a process can access its virtual address space. However, threads cannot access memory that belongs to a different process.
Distributed systems and networks:-
Network-based multi-user interaction systems like network games typically include a database shared among the players that are physically distributed and interact with each other over the network. Currently, network game developers need to implement the shared database and inter-player communications from scratch.
Security:-
As security side every game, there's an excellent risk that, within the heat of the instant, data are going to be transmitted that you simply better keep to yourself. There are many threats to your IT.
Define on the whole data protection matters when developing games software may cause significant competitive advantages. Data controllers are obliged under the GDPR to attenuate data collection and processing, using, as an example , anonymization or pseudonymization of private data where feasible.

A(n) _____ is a network connection device that can build tables that identify addresses on each network.
Answer:
Dynamic Router
Explanation:
A dynamic router is a network connection device that can build tables that identify addresses on each network.
What is Dynamic network?Dynamic networks are networks that vary over time; their vertices are often not binary and instead represent a probability for having a link between two nodes.
Statistical approaches or computer simulations are often necessary to explore how such networks evolve, adapt or respond to external intervention.
DNA statistical tools are generally optimized for large-scale networks and admit the analysis of multiple networks simultaneously in which, there are multiple types of nodes (multi-node) and multiple types of links (multi-plex).
Therefore, A dynamic router is a network connection device that can build tables that identify addresses on each network.

A process needs 103 KB of memory in order to run. If the system on which it is to run uses paging with 2 KB pages, how many frames in memory are needed
Answer: 52
Explanation:
Following the information given in the question, we are informed that a process needs 103 KB of memory in order to run and that the system on which it is to run uses paging with 2KB pages, then the number of frames in memory that are needed will be:
= 103/2
= 51.5
= 52 approximately
Therefore, 52 frames in memory are needed.
Can anyone decipher these? There a bit random. Maybe binary but if there are other ways please include them.
Answer:
Explanation:
so this is what "format" is about, it's saying what do the ones and zeros represent. b/c the bits can represent lots of different things , like letters with ascii code , and that's got several types. some are 8 bits, some are 16 bits, the questions you've shown are in groups of 5 which is really not a "thing" in binary, it's always by twos, without some type of "frame work" around the bits, we won't know what they represent, if that is helping? the important part is what is the "frame work" that these bits are in.
all of your questions seem to have some "art" thing going on, they make some kinda of binary artwork, for what they are saying, that's not what's important. Other than if they form palindromes, maybe that's what the questions are really about, how these do from palindromes, that is, they read the same backwards as forwards... I know.. why would anyone read backwards.. but a computer can do that pretty quickly, sooo sometimes to check, it will read forwards and backwards.. but when there is a palindrome, the computer is "confused"
this is also a big big part of "typing" not like on a keyboard but when you program, and you say that your variables are of a certain type, like a char, or a string, or a double, you are specifying how many bits will be used to represent your data. so then when you put the ones and zeros into the memory , ( think RAM) then it's stored in groups of what ever size you've determined. hmmmm does this help?

The manager of the Super Supermarket would like to be able to compute the unit price for products sold there. To do this, the program should input the name and price of an item per pound and its weight in pounds and ounces. Then it should determine and display the unit price (the price per ounce) of that item and the total cost of the amount purchased. You will need the following variables: ItemName Pounds Ounces PoundPrice TotalPrice UnitPriceYou will need the following formulas: UnitPrice = PoundPrice/16 TotalPrice = PoundPrice * (Pounds + Ounces/16)
Answer:
The program in Python is as follows:
name = input("Name of item: ")
PoundPrice = int(input("Pound Price: "))
Pounds = int(input("Weight (pounds): "))
Ounces = int(input("Weight (ounce): "))
UnitPrice = PoundPrice/16
TotalPrice = PoundPrice * (Pounds + Ounces/16)
print("Unit Price:",UnitPrice)
print("Total Price:",TotalPrice)
Explanation:
This gets the name of the item
name = input("Name of item: ")
This gets the pound price
PoundPrice = int(input("Pound Price: "))
This gets the weight in pounds
Pounds = int(input("Weight (pounds): "))
This gets the weight in ounces
Ounces = int(input("Weight (ounce): "))
This calculates the unit price
UnitPrice = PoundPrice/16
This calculates the total price
TotalPrice = PoundPrice * (Pounds + Ounces/16)
This prints the unit price
print("Unit Price:",UnitPrice)
This prints the total price
print("Total Price:",TotalPrice)

When a database stores the majority of data in RAM rather than in hard disks, it is referred to as a(n) _____ database.
Answer:
in-memory.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
In this context, data management is a type of infrastructure service that avails businesses (companies) the ability to store and manage corporate data while providing capabilities for analyzing these data.
Hence, a database management system (DBMS) is a system that enables an organization or business firm to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data.
Radom Access Memory (RAM) can be defined as the main memory of a computer system which allow users to store commands and data temporarily.
Generally, the Radom Access Memory (RAM) is a volatile memory and as such can only retain data temporarily.
All software applications temporarily stores and retrieves data from a Radom Access Memory (RAM) in computer, this is to ensure that informations are quickly accessible, therefore it supports read and write of files.
Generally, when a database stores the majority of data in random access memory (RAM) rather than in hard disks, it is referred to as an in-memory database (IMDB).
An in-memory database (IMDB) is designed to primarily to store data in the main memory of a computer system rather than on a hard-disk drive, so as to enhance a quicker response time for the database management system (DBMS).

Explanation:
Search engine optimization (SEO) can be defined as a strategic process which typically involves improving and maximizing the quantity and quality of the number of visitors (website traffics) to a particular website by making it appear topmost among the list of results from a search engine such as Goo-gle, Bing, Yah-oo etc.
This ultimately implies that, search engine optimization (SEO) helps individuals and business firms to maximize the amount of traffic generated by their website i.e strategically placing their website at the top of the results returned by a search engine through the use of algorithms, keywords and phrases, hierarchy, website updates etc.
Hence, search engine optimization (SEO) is focused on improving the ranking in user searches by simply increasing the probability (chances) of a specific website emerging at the top of a web search.
Typically, this is achieved through the proper use of descriptive page titles and heading tags with appropriate keywords.
Generally, the conversion rate is mainly designed to be the highest for keyword searches classified as buyers because they're the main source of revenue for a business and by extension profits.
Write a program named edit_data.py that asks a person their age. Accept an int. Use a custom exception to return a message if the number entered is an int that is less than 1 or greater than 115. Create an exception that catches an error if a non int is entered.
An error that occurs while a program is being run is an exception. Non-programmers see exceptions as examples that do not follow a general rule.
What is the programming?
In computer science, the term "exception" also has the following connotation: It signifies that the issue is an uncommon occurrence; it is the "exception to the rule." Some programming languages use the mechanism known as exception handling to deal with problems automatically. Exception handling is built into several programming languages, including C++, Objective-C, PHP, Java, Ruby, Python, and many others.
In order to manage errors, programs often save the state of execution at the time the problem occurred and interrupt their usual operation to run an exception handler, which is a particular function or section of code. Depending on the type of error that had occurred, the error handler can "correct" the issue and the application can then continue using the previously saved data.
Thus, An error that occurs while a program is being run is an exception.
