Suggested March 2024 Banker’s Algorithm In Operating System

What is Banker’s Algorithm?

Banker’s Algorithm is used majorly in the banking system to avoid deadlock. It helps you to identify whether a loan will be given or not.

This algorithm is used to test for safely simulating the allocation for determining the maximum amount available for all resources. It also checks for all the possible activities before determining whether allocation should be continued or not.

For example, there are X number of account holders of a specific bank, and the total amount of money of their accounts is G.

When the bank processes a car loan, the software system subtracts the amount of loan granted for purchasing a car from the total money ( G+ Fixed deposit + Monthly Income Scheme + Gold, etc.) that the bank has.

It also checks that the difference is more than or not G. It only processes the car loan when the bank has sufficient money even if all account holders withdraw the money G simultaneously.

In this operating system tutorial, you will learn:

Banker’s Algorithm Notations

Here is an important notation used in Banker’s algorithm:

X: Indicates the total number of processes of the system.

Y: Indicates the total number of resources present in the system.


[I: Y] indicate which resource is available.


[l:X,l: Y]: Expression of the maximum number of resources of type j or process i


[l:X,l:Y]. Indicate where process you have received a resource of type j


Express how many more resources can be allocated in the future

Example of Banker’s algorithm

Assume that we have the following resources:

5 Pen drives

2 Printers

4 Scanners

3 Hard disks

Here, we have created a vector representing total resources: Available = (5, 2, 4, 3).

Assume there are four processes. The available resources are already allocated as per the matrix table below.

Process Name Pen Drives Printer Scanner Hard disk

P 2 0 1 1

Q 0 1 0 0

R 1 0 1 1

S 1 1 0 1

Total 4 2 2 3

Here, the allocated resources is the total of these columns:

Allocated = (4, 2, 2, 3).

We also create a Matrix to display the number of each resource required for all the processes. This matrix is called Need=(3,0,2,2)

Process Name Pen Drives Printer Scanner Hard disk

P 1 1 0 0

Q 0 1 1 2

R 2 1 0 0

S 0 0 1 0

The available vector will be :

Available=Available- Allocated

= (5, 2, 4, 3) -(4, 2, 2, 3)

=(1, 0, 2, 0)

Resource Request Algorithm

Resource request algorithm enables you to represent the system behavior when a specific process makes a resource request.

Let understand this by the following steps:

Step 1) When a total requested instance of all resources is lesser than the process, move to step 2.

Step 2) When a requested instance of each and every resource type is lesser compared to the available resources of each type, it will be processed to the next step. Otherwise, the process requires to wait because of the unavailability of sufficient resources.

Step 3) Resource is allocated as shown in the below given Pseudocode.

Available = Available – Request (y) Allocation(x) = Allocation(x) + Request(x) Need(x) = Need(x) - Request(x)

This final step is performed because the system needs to assume that resources have been allocated. So that there should be less resources available after allocation.

Characteristics of Banker’s Algorithm

Here are important characteristics of banker’s algorithm:

Keep many resources that satisfy the requirement of at least one client

Whenever a process gets all its resources, it needs to return them in a restricted period.

When a process requests a resource, it needs to wait

The system has a limited number of resources

Advance feature for max resource allocation

Here, are cons/drawbacks of using banker’s algorithm

Does not allow the process to change its Maximum need while processing

It allows all requests to be granted in restricted time, but one year is a fixed period for that.


Banker’s algorithm is used majorly in the banking system to avoid deadlock. It helps you to identify whether a loan will be given or not.

Notations used in banker’s algorithms are 1) Available 2) Max 3) Allocation 4) Need

Resource request algorithm enables you to represent the system behavior when a specific process makes a resource request.

Banker’s algorithm keeps many resources that satisfy the requirement of at least one client

The biggest drawback of banker’s algorithm this that it does not allow the process to change its Maximum need while processing.

Best Business Intelligence Software And Business Operating System Options For 2023

Every day there’s more usage of technology-intensive tools set up of standard ones. Old suggestions used to be dull, expensive, mostly untrue, and frequently harmful. Because of this, business intelligence isn’t what it use to imply a decade past.

Now, improved automation is making organizations to go to the look-out for up-to-date company intelligence applications to keep up with the newest worldwide technology dictate.

We are aware that information is the major component that’s driving this shift. Take for example our rising demand for datification to boost our small in addition to important affairs.

Businesses around the globe are utilizing datification to flip our everyday lives into a massive mass of information. That is the reason why datification is the center of information science.

This exceptional area of mathematics works closely together with business intelligence (BI) and a number of different areas e.g., scientific computing, qualitative data, etc., to have the ability to infer lively meaning through data handling.

What is business intelligence and BI Software?

To put it simply, BI is a technology-based process that puts raw data into a readable form. Business and data specialists figure out this raw data and turn it into easy visual facts to aid the decision-making process. Because people tend to make better decisions when they have better information.

BI uses many software with technical and nontechnical sides to turn data into useful facts. These facts greatly assist business organizations in making the right decisions as well as solve serious problems.

The usual BI process takes many complex tools, software applications, and special methods. BI helps businesses in setting up an extensive data collection mechanism through many different sources.

The purpose of extracting information through this process is to develop infographics, dashboards, analytical outcome reports, etc. All of this information communicates results with corporate executives or anyone with the power to make strategic business decisions.

Best Business Operating System

We can go about earning a case of a single OS against another and confuse you to no limitation. Or we can straight down to the greatest possible alternative and tell you why it’s, in reality, that the right for you.

We opt to go for the latter. Because honestly, the entire purpose of the guide is to create apparently difficult decisions simple for you.

The saturated spectrum of OS gives us the same names whenever we need a system in tune with our interests.

It normally leaves people to feel that harmonious or not, only those few names e.g., Windows, macOS, Unix, Android, chúng tôi their potential choices.

But if you dig a bit to look behind the apparent you’ll discover the most above-mentioned option apparently hiding in the shadows.

Though the ideal OS alternative — Steam — for companies that we mean to discuss now isn’t really hiding from the audience, it’s still much talked about specially given the unending collection of values it’s adding to companies globally.

For those who, like most others, have overlooked the overall look of Linux operating systems as a rewarding alternative to almost all of the present OS, now’s the time to mend this.

It’s being estimated that Linux has been defined to replace the OS stadium as you know it now owing to the dizzying assortment of futuristic features which are sweeping the tech bigwigs their feet off. Take Huawei’s dependence on Linux Deepin because of its MateBook notebook for instance.

Why go with Linux for your business?

2024 isn’t merely the year of additional technical improvement in case anything, 2023 appears to be business-centric than anything else irrespective of the topic area or character.

You’ll also realize that the integration of Linux programs is rather simple based upon the particular Linux distribution — distro — you pick coordination with your computing necessity.

The top still is how you don’t need to discard your position infrastructure to correct the flexibility which open-source applications and cost-effective performance of Linux provides. It’s actually a free replacement for different OSs, which companies find over a bit hard to grasp.

Linux doesn’t need purchase awards for your software unless you’re a sort of company that needs expert assistance from paid tech support.

That may be worked off, given the selection of Linux platform administrator training applications available now which efficiently ticks off an overhead the listing of companies’ overall price.

Best Linux for Businesses in 2023

So how do you figure out which distro is the best fit for your business? Because Linux OS comes in a vast variety with several futuristic business-grade features. Well, we have put together a list of top of the range distribution based on a criterion that includes:




Let’s have a look at some of the best Linux in 2023 with critical uptime, unwavering support, and practical capabilities.


CentOS is just one of the most popular Linux server distributions. Linux has generated CentOS on the base of Red Hat Enterprise Linux (RHEL) from the funding support of Red Hat from 2014.

Assembled with nice Gnome — the default desktop for Red Hat & Fedora — familiarity combined with broadly endorsed Red Hat package manager (RPM) open source, CentOS makes for an extremely harmonious enterprise-class Linux distro for both workstations and servers.


Slackware is the oldest Softlanding established Linux distro that’s busy to date. Patrick Volkerding made it in 1993. Slackware supplied bases for several distributions such as SUSE Linux distro.

It supplies end-users max control than any other Linux OS however this attribute has either side to think about.

For example, while it provides you tremendous command management, this lightweight supply lacks the graphical settings and applications dependence resolution mechanism. If You’re Looking for a customized distro, Slackware is the one to suit your needs.


This Linux distro specifically caters to small and medium enterprises. It acts as a network gateway as well as a network server that you can manage completely from a web-based interface.

ClearOS is an effective alternative to commercially supported software solutions with commercial tech support availability. Like CentOS, this distribution also has relatively simple configuration and maintenance due to congenital RHEL foundation packages.

But the similarities end here because unlike CentOS, ClearOS is strictly a server platform. Its complete web dependency makes the use of individual consoles redundant after distro installation.


Ubuntu – the ever-increasing popularity of Linux desktop distribution – makes people feel it is most compatible with personal use. This is hardly true given its well-recognized community support system.

Ubuntu provides full stability and flexibility to its end-user with a free version called Ubuntu Server for backend requirements.

Ubuntu is based on another Linux distro called Debian. This means that Ubuntu can use Debian packages using the Advanced Package Tools (Apt) management system to add or remove software.

If you choose to choose Ubuntu as your Linux OS, you will get the best support from its massive userbase. The latest releases are marketed as long-term support (LTS) supported distros with a 5-year maintenance option for professional support.


The IPFire distro is often considered a Linux watchdog due to its exceptional security solutions. This is particularly relevant for small businesses who are more vulnerable to cyber threats to protect their networks.

Install this distribution and leave it to manage IP addresses, firewall security, and employee monitoring to check security or behavior. Although it is not difficult to maintain, IPFire will definitely require expert-level knowledge to get it up and running.

There are several reasons for its complex configuration. for example; Nature different from any other Linux version, tow node, proxy protocol, etc.

OpenSUSE or more accurately SUSE Linux Professional is another Linux distribution community program. It is operated by SUSE Linux GmbH which is to be used as the basis of commercial SUSE Enterprise.

Unlike CentOS and ClearOS, OpenSUSE is designed with a robust desktop environment, with its window manager called K Development Environment (KDE). KDE comes with a graphical interface that makes it a heavyweight distro to be highly compatible with TimeWorn hardware systems.

For example, Raspberry Pi single-board computer. It is a stable and secure OS due to the latest release of the rolling model with frequent update availability.

How Sort() Algorithm Function Work In C++

Introduction to C++ sort()

The sort() function in C++ sorts a number of elements or a list of elements within the first to last elements in an ascending or descending order. This function executes the sorting operation within the specified list or range, starting with the first element and ending with the last element. The sort function takes in two parameters as arguments and returns the result of sorting. Comparing the elements is the main operation. There can be exceptions in case the elements that are being compared encounter any exceptions. The most common ways to sort are in either an ascending order or a descending order.

Start Your Free Software Development Course

Syntax and parameters:

The standard syntax for the sort function includes of sort keyword and two parameters. The return output will be the result of the sort operation.

void sort(RIt first, RIt last);

The parameters implemented in the above syntax are RandomIt, first and last.

Here the first and last are the range between whose sorting is to be done; the first notifies the first element of the list, while the last denotes the last element.

How sort() Algorithm Function work in C++?

The basic method by which the sorting algorithm works is based on comparison.

The sorting function attempts to compare each and every element of the list.

The comparison works in a way as comparing the first element with the second element, followed by the second and third, and so on. Here the comparison operator “<” is widely used.

So, simply speaking, the sort function at a time picks two values or elements of a list, then compare these two values to identify smaller and bigger value and arrange them in a form, ascending or descending, whichever is required.

Examples of C++ sort()

We will have a list of values, which will be unsorted and not in any order, and we will aim to correct the list by implementing the sort function.

Example #1

Our first example takes in an array of number values, unsorted, and we will implement the sort, and the output will be a list of values in a sorted format.


using namespace std; int main() { int arr1[] = {99,91,94,96}; int n = sizeof(arr1)/sizeof(arr1[0]); sort(arr1, arr1+n); cout << “n List of Array after sorting is: “; for (int i = 0; i < n; ++i) cout << arr1[i] << ” “; return 0; }


We have our system files and namespace, followed by initializing the main code. Then we have our first array variable of integer type, which holds a list of four numbers totally unsorted, following no order.

Then we have another integer variable followed by the sort function. We then print s statement, which then comes in our for statement, which will pick and print the numbers in a sorted format.

Upon successful execution, the output of the program will be a statement and a list of four numbers in a sorted format.


As explained and expected, the program generates an output statement followed by the corrected and sorted list of numbers. The sorting operation is performed in ascending order.

Example #2


using namespace std; void show(int a[]) { for(int b = 0; b < 10; ++b) cout << a[b] << ” “; } int main() { int a[10]= {3,4,1,0,5,7,8,6,9}; cout << “n This is the unsorted list: “; show(a); sort(a, a+10); cout << “nn Here’s the output of sort operation:: “; show(a); return 0; }


Started with required system files followed by declaring the login for the program. Then we have our main block of code, where we have an array with integer values followed by a print statement.

Then we have our sort function and parameter values passed, followed by the print statement and the final output.

The expected output is two statements, which include a list of the unsorted array and another list which is the output of the sorting operation.


Our code executed as expected, and the output is proper.

Example #3


int main() { std::cout << ‘n’; std::cout << “Sorting done with simple < operator: “; std::cout << ‘n’; std::sort(list.begin(), list.end()); for (auto a : list) { std::cout << a << “  “; } std::cout << ‘n’; std::cout << “n This is output of sorting using custom function: “; std::cout << ‘n’; struct { bool operator()(int a, int b) const { return a < b; } } customLess; std::sort(list.begin(), list.end(), customLess); for (auto a : list) { std::cout << a << ” “; } std::cout << ‘n’; }


Like the earlier example, we begin with the required system files and a main block. Then we have our array of values, followed by a few lines of code for output, where we first print the sorted list as a result of our sort operation. Then within our second method, we have a custom function, which creates a struct and passes the values.

Then we have our sort function, which starts with begin, then the end, and the custom function.


As expected, the output of the code is that the sorting has been done in two different formats using two methods.


In C++, we use the sort() function to sort a list of values. This function allows us to perform sorting in either ascending or descending order. We saw a few methods and ways to implement the sort function.

Key Elements In Quality Management System (Qms)

A quality management system (QMS) is a framework of an organization’s policies, processes, and procedures to ensure that its products or services meet the required quality standards. The goal of a QMS is to continuously improve the quality of products and services, leading to increased customer satisfaction and business success. Several key elements comprise a QMS, including a quality policy, quality objectives, quality procedures, and continuous improvement.

In addition to these elements, several tools and techniques can support a QMS, such as Six Sigma and lean manufacturing. Implementing a QMS requires a company-wide commitment to quality and the active participation of all employees in the continuous improvement process.

It also requires strong leadership to set the vision and direction for quality efforts and provide support and resources to meet quality goals. By effectively managing the quality of its products and services, an organization can increase customer satisfaction, improve business performance, and stay ahead of the competition.

What are the Key Elements of a Quality Management System (QMS)?

A quality management system (QMS) is a framework of an organization’s policies, processes, and procedures to ensure that its products or services meet the required quality standards. Several key elements make up a QMS, which include −

Quality Policy − The quality policy is a statement of the organization’s commitment to quality and its goals for quality improvement. It should be clear and concise and should be communicated to all employees.

Quality objectives are specific, measurable goals that an organization sets for improving the quality of its products or services. These objectives should be aligned with the organization’s overall business goals and regularly reviewed and updated.

Quality Manual − The quality manual is a document that outlines the organization’s quality policies and procedures. It should provide an overview of the QMS and detailed information on the processes and procedures used to ensure quality.

Quality Procedures − Quality procedures are the specific steps an organization follows to ensure that its products or services meet the required quality standards. These procedures should be documented and followed consistently to ensure quality is maintained.

Quality records provide evidence of the organization’s compliance with its quality policies and procedures. They may include records of quality inspections, test results, and customer feedback.

Quality Audits − Quality audits are periodic reviews of the organization’s QMS to ensure that it is effective and compliant with relevant standards and regulations. Audits may be conducted by internal or external auditors and may include both documented and verbal reviews.

Continuous Improvement − Continuous improvement is a key element of a QMS, as it involves identifying and implementing opportunities for improvement in the organization’s products, services, and processes. Continuous improvement may involve analyzing data, implementing changes based on findings, and involving all employees in the improvement process.

Customer Focus − A QMS should be centered around meeting the needs and expectations of customers. This involves understanding their requirements and continuously improving products and services to meet those needs.

In addition to the key elements of a quality management system (QMS), there are several other important considerations for organizations to keep in mind when implementing and maintaining a QMS. These include −

Standardization − An organization needs consistent policies, processes, and procedures to ensure that quality is consistently maintained. This may involve adopting industry standards or developing internal standards specific to the organization’s products and services.

Communication − Effective communication is crucial for the success of a QMS. This includes communication within the organization, as well as communication with customers and other stakeholders.

Training − Ensuring all employees are trained on the organization’s QMS is essential for its success. Training should cover the policies, procedures, and tools used to ensure quality, as well as the roles and responsibilities of each employee in the quality process.

Resource Allocation − Adequate resources must be allocated to support the QMS, including personnel, equipment, and financial resources. This may involve investing in new technologies or training programs to support quality efforts.

Risk Management − A QMS should include a risk management plan to identify and mitigate potential risks to the quality of products and services. This may involve conducting risk assessments, implementing controls to reduce risk, and monitoring and reviewing risks on an ongoing basis.

Performance Measurement − It is important to measure the performance of the QMS to ensure that it is effective and achieves its desired outcomes. This may involve gathering data on the performance of processes, identifying areas for improvement, and implementing changes based on findings.

Customer Feedback − Gathering and analyzing customer feedback is an important aspect of a QMS, as it helps identify areas for improvement and ensure that products and services meet customer needs. This may involve collecting customer feedback through surveys, focus groups, or other methods.


We may draw the conclusion that these eight components are essential to guaranteeing TQM’s success in a company and that the supervisor plays a significant role in fostering these components at work. Business entities cannot successfully adopt TQM without these components.

The explanation above makes it quite evident that TQM would be seriously flawed—in fact, it would be lacking—without the inclusion of integrity, ethics, and trust. The key to helping the organization build a TQM climate is training. Teamwork and leadership go hand in hand. The entire TQM process is hampered by a lack of communication between departments, managers, and employees.

Lru Approximation (Second Chance Algorithm)

Introduction LRU Approximation Algorithm

To keep track of which pages are currently in memory, the LRU approximation algorithm employs a circular buffer. Each page receives a reference bit, which is initially set to 0. When a page is accessed, the reference bit on that page is set to 1. The operating system scans the circular buffer on a regular basis, looking for pages with reference bit 0. When such a page is discovered, it is replaced with the new one.

During the scan, if a page with reference bit 1 is found, the reference bit is set to 0 and the scan proceeds. By doing this, the page has a second chance to stay in your memory. The scan is repeated until a page with reference bit 0 is located if one is not found the first time.

The LRU approximation algorithm is not a true LRU algorithm, but it provides a good approximation with significantly less overhead. It is a straightforward and efficient algorithm that is found in many operating systems. However, in some cases, such as when the working set size is larger than the buffer size or when there are long periods of high memory activity, it may not perform well. More sophisticated page replacement algorithms may be required in such cases.

Advantages of LRU Approximation algorithm

Simplicity − The LRU approximation algorithm is simple to implement and has a low computational overhead. Each page only requires a single reference bit to be set and a circular buffer to store the pages.

Low Overhead − Since it does not require complex data structures or frequent memory scans, the LRU approximation algorithm has a low overhead. The algorithm only needs to scan the memory on a regular basis to look for pages with a reference bit of 0.

Good Performance − For most applications, the LRU approximation algorithm performs well, especially when the working set size is smaller than the buffer size. It can keep the most frequently used pages in memory while removing pages that are no longer needed.

Easy to Combine with Other Algorithms − To improve performance, the LRU approximation algorithm can be easily combined with other algorithms. It can be combined with the Clock algorithm, for example, to provide a more efficient page replacement algorithm.

Fairness − The LRU approximation algorithm is a fair algorithm that ensures all pages in memory have an equal chance of being evicted. This prevents pages from being evicted from memory unnecessarily and improves system performance overall.

Adaptability − The LRU approximation algorithm is adaptable and can be configured to work well in various system configurations. For example, the buffer size can be changed depending on the system’s memory requirements, and the scanning frequency can be changed depending on the system’s workload.

Despite its benefits, the LRU approximation (Second Chance) algorithm has some drawbacks, which include −

Limited accuracy in choosing the least recently used page to evict

Poor performance when the working set size exceeds the buffer size

Increased memory scanning can impact system performance

Limited adaptability in certain system configurations

Complexity in implementation for multi-processor systems

The LRU approximation algorithm has shortcomings in terms of accuracy, performance, and adaptability. These constraints can have an impact on system performance in certain scenarios, and the algorithm may need to be tweaked to work optimally in different system configurations.


An efficient page replacement approach that works well in most situations is the LRU approximation (Second Chance) algorithm. We covered LRU Approximation in this article along with some of its benefits and drawbacks. It may be modified to fit different system configurations and is easy to apply. The system, meanwhile, has flaws in its performance, flexibility, and accuracy. When the working set size is larger than the buffer size, its performance could suffer because it might not always select the least recently used page for eviction.
