Basic Concepts of Operating Systems

Definition and Purpose

An operating system (OS) is a software package that manages a computer’s hardware resources and provides a platform for running applications. It serves as a link between the user and the device by executing commands such as running programs, processing files, or connecting to a network. For example, the OS coordinates the processor and RAM, allowing you to edit text and watch video at the same time.

Types of Operating Systems

• Multitasking:  Windows and macOS support running multiple processes at the same time, which is essential for modern users. Windows allows you to run a browser, video editor, and antivirus simultaneously.
• Embedded OS:  Used in resource-constrained devices such as microcontrollers in medical equipment or household appliances. FreeRTOS provides the real-time stability needed for CPR systems.
• Server OS:  Linux and Windows Server are optimized for processing large amounts of data. For example, Amazon Web Services uses a modified version of Linux to manage cloud servers.

Historical Evolution

OS development has come a long way from the first single-tasking systems to today’s feature-rich platforms. In the 1960s, IBM OS/360 laid the foundation for commercial OSes. In the 1980s, the advent of the graphical interface, as in the Apple Macintosh, revolutionized user interaction. Today’s OSes, such as Android, support billions of devices, from smartphones to smart watches.

Core Components

Kernel Functions

The kernel is the central component of the OS that is responsible for resource management. It includes modules for handling memory, processes, and devices: the Linux kernel supports virtualization features, allowing multiple operating systems to run on a single physical server.

Process Management

A process is a program in a state of execution. The OS manages processes using algorithms such as Priority Scheduling. For example, in real-time systems, high-priority tasks, such as handling alarms, run faster than background processes, such as loading data.

Memory Management

Memory management allows you to use RAM efficiently. Virtual memory in Windows allows you to run a program even if physical memory is insufficient, using part of the hard disk as an extension of RAM.

User Interface

Command Line Interface

The CLI gives users access to powerful tools. In Linux, the rsync command allows you to synchronize data between servers, which is indispensable for system administrators.

Graphical User Interface

GUIs make computers easier to use for a wide audience. An example is macOS with Dock, which allows you to quickly switch between applications using a mouse or touch screen.

Modern Interface Innovations

Modern interfaces integrate technologies such as augmented reality. For example, Microsoft HoloLens allows you to interact with apps through gestures and voice commands.

Resource Management

CPU Scheduling

The OS manages the allocation of CPU time. For example, Linux’s Completely Fair Scheduler evenly distributes resources among processes, minimizing latency.

Memory Allocation

The OS allocates memory between applications: macOS isolates memory for each process, preventing data leakage between programs.

Device Management

The OS communicates with peripheral devices through drivers. Windows automatically configures printers and cameras through Plug-and-Play etc.

File Systems

File Organization

A file system structures data. An example is EXT4 in Linux, which provides fast file indexing, which speeds up information retrieval.

Storage Management

The OS manages storage by dividing it into partitions. For example, in enterprise systems, ZFS supports real-time data backup.

Access Control

Access control protects files. Windows uses an ACL (Access Control List) model to restrict access to individual users.

Security Features

User Authentication

Modern operating systems are implementing biometric authentication. For example, Windows Hello uses facial scanning to log in.

Permission Systems

Permission systems protect resources – in Linux, the chmod command allows you to change file permissions.

Security Protocols

Operating systems support data encryption – macOS uses FileVault to protect disk contents.

Software Integration

Application Support

The OS provides a platform for applications to run on. A good example here would be Android. It supports APIs that simplify the development of mobile applications.

Driver Management

Driver management is critical for compatibility. Windows Update regularly updates graphics card drivers to ensure support for new games – this is a very important feature.

System Updates

OSes fix vulnerabilities through updates. Ubuntu, for example, releases monthly patches to improve security.

Performance Optimization

Task Prioritization

The OS prioritizes tasks. For example, Windows Real Mode allows programs to reserve CPU time for critical tasks such as video processing.

Resource Allocation

Dynamic resource allocation improves performance. For example, macOS optimizes memory usage by closing inactive applications.

System Monitoring

Tools like htop in Linux allow the administrator to see resource utilization in real time.

Modern Developments

Cloud Integration

Operating systems are integrating with cloud platforms. An example is Windows 365, which allows you to work in the cloud without depending on local hardware.

Mobile Operating Systems

Mobile operating systems support billions of devices. For example, iOS offers a power-saving mode that extends the life of the device.

Future Trends

The future of OS is tied to AI. For example, Windows Copilot uses AI to automate routine tasks like file management.

Digital signage for government has become an important tool in the public sector, providing effective interaction with citizens and supporting internal operations. For example, in municipalities, signage informs citizens about weather conditions, road works, or emergencies. A robust operating system (OS) ensures that such systems function smoothly, even under heavy loads or cyberattacks.

Security Requirements

Government digital signage processes and broadcasts data that is often of a sensitive or critical nature. For example, in ministry buildings, digital screens transmit meeting schedule information that is accessible only to certain groups of employees. To ensure protection, systems must meet stringent requirements: data encryption, resilience to failure, and tamper-proofing. Without these measures, vulnerabilities can be exploited by attackers, as has already happened in incidents involving content spoofing on public screens.

Regulatory Framework

Digital signage operating systems must comply with international and national regulatory requirements. For example, EU data protection regulation (GDPR) mandates the use of technologies that prevent unauthorized access to personal data. Failure to comply can lead not only to data breaches but also to legal consequences, including hefty fines.

Implementation Standards

The use of international standards, like ISO/IEC 27001, provides an opportunity to harmonize approaches to data protection and provides confidence in the system. For example, the use of this standard in digital signage OS allows to streamline risk management and develop measures to minimize the impact of incidents.

Operating System Architecture

Core Security Components

The core security components of an operating system include modules such as a secure kernel that supports process isolation and built-in encryption tools. Hardware security modules (TPMs) are used to securely store cryptographic keys, preventing them from being compromised.

Access Control Mechanisms

Access control involves multiple layers of identification and authentication. Biometrics such as fingerprints or facial recognition are used alongside standard passwords. These measures significantly reduce the likelihood of system compromise.

Network Integration

Digital signage systems must be integrated into the overall infrastructure via secure networks. The use of virtual private networks (VPNs) and protocols such as TLS helps prevent data interception. This is especially important for signage centrally managed from a single hub but deployed across different regions.

Security Features Implementation

Authentication Systems

Modern authentication systems include two-factor and multi-factor methods. For example, administrators managing the system can use tokens or mobile applications to generate one-time codes. This approach makes unauthorized access more difficult, even if one layer of protection is compromised.

Encryption Protocols

Encryption protocols such as AES-256 and RSA are used to protect data. These technologies ensure that transmitted data remains confidential, even if traffic is intercepted – encrypting content between the server and digital signage prevents intruders from tampering with or accessing the data etc.

Remote Management Tools

Centralized system management is implemented using tools such as Ansible or Microsoft Endpoint Manager. These solutions enable remote software updates, system health monitoring, and troubleshooting while minimizing the risks associated with physical intervention.

Compliance and Certification

Government Standards

The use of certified solutions, such as Common Criteria-certified operating systems, provides assurance of compliance with strict security protocols.

Security Clearances

Access to a system is granted only to individuals who have been properly vetted and certified. For instance, employees working with sensitive data must operate secure workstations equipped with hardware keys.

Audit Requirements

Regular audits may reveal that an outdated software library serves as an entry point for attacks, enabling timely remediation.

Risk Management

Threat Assessment

Threat assessment involves analyzing potential attack scenarios and their likelihood. For example, the MITRE ATT&CK framework helps predict attackers’ actions, including techniques like phishing to gain unauthorized access to the system.

Vulnerability Management

Automated tools such as Tenable.io assist in identifying and addressing vulnerabilities; after installing an update to third-party software, a newly discovered bug might require an urgent patch.

Incident Response

Maintaining regular data backups can minimize the impact of ransomware attacks, enabling service restoration without the need to pay a ransom.

Content Management Security

Distribution Protocols

The use of secure data transfer protocols, such as SFTP or HTTPS, prevents content interception or spoofing.

Content Verification

Content integrity is verified using cryptographic hash functions like SHA-256. This ensures that transmitted files have not been altered by malicious actors.

Update Management

Centralized update management via platforms like Puppet ensures timely delivery of patches and new features. Systems can automatically install critical security updates, minimizing the risk of vulnerabilities.

Network Infrastructure

Isolated Networks

For mission-critical facilities such as medical facilities or military bases, digital signage operates on isolated networks. This eliminates the possibility of remote access from the outside.

Firewall Configuration

Firewall configuration (NGFW) provides application-level traffic filtering and blocks suspicious requests coming from unknown IP addresses.

Monitoring Systems

Splunk, Zabbix, and other monitoring systems monitor activity in real time to help identify anomalies. If a hacking attempt is detected, the system can automatically send a notification to the administrator.

Maintenance and Support

Security Updates

Regular security updates are necessary to prevent exploitation of vulnerabilities. For example, automatically deploying patches through WSUS reduces the risk of exploiting outdated components.

Personnel Training

Personnel training includes regular drills based on real-world attack scenarios.

Emergency Procedures

Emergency response scenarios include plans for recovering from cyberattacks or technical failures. One of these is a backup server. It allows for instant switching to alternate channels if the primary equipment fails.

Future Developments

Emerging Technologies

AI-based systems can automatically categorize suspicious activity and block it before damage is done. In general, the use of quantum computing to encrypt data and machine learning to analyze threats promises to improve security.

Integration Possibilities

Integrating digital signage with other government systems can enhance their functionality. For example, data from surveillance cameras can automatically change the information displayed depending on the density of human traffic.

Security Enhancements

Future enhancements may include the use of post-quantum encryption algorithms and blockchain technologies for content verification. This will make systems even more secure against current and future threats.

However, soon Linux will not only catch up with Windows and macOS but also surpass its competitors in the desktop market. Here are 7 reasons why this will happen.

Why Will Desktop Users Choose Linux in 2024?

1. The Cost of New PCs Might Drive People to Keep Their Old Machines and Install Linux

The trend began during the pandemic when many needed laptops for working from home. The computer hardware industry suffered due to supply chain issues: new PC chips were hard to come by. People were buying equipment at old prices, and new stock arrived slowly and at higher prices.

Don’t forget about inflation and rising interest rates. Now, even buying laptops on credit has become less feasible. Although the situation slightly stabilized by the end of 2022, both manufacturers and potential buyers need time to find balance in the new reality.

The war in Ukraine has also had an impact. Not just for Ukrainians, but globally, as several well-known companies exited the Russian market (Apple, ASUS, Dell, IBM, etc.) to avoid funding terrorism. Consequently, their profits fell, and product prices rose.

Even though the PC market looks relatively stable now, external economic factors might push people to refrain from buying new tech. As Microsoft and Apple stop supporting older machines, more users will install lightweight Linux distributions on them in 2024.

2. Desktop Linux Continues to Improve

Although Linux is often associated with command-line usage, desktop versions of this OS now present an attractive alternative to Windows and macOS.

Distributions like Zorin OS are clearly aimed at current Windows and macOS users by providing similar user interfaces. Other distributions also strive to make their systems more familiar to non-Linux enthusiasts. If you don’t need it, you won’t see text consoles during startup or use the command line. Only a visual interface and familiar mouse clicks.

While installing a new OS might seem complicated, modern Linux systems are more intuitive than early window managers from the 80s and 90s.

3. Microsoft and Apple Are Ending Support for Older Versions of Their OS

As Microsoft and Apple try to move users to newer versions, they will end support for older ones.

Microsoft stopped providing security updates for Windows 7 and Windows 8 users in January 2024. In September 2022, Microsoft announced that it would end support for Windows 10 version 21H1.

Apple systematically cuts support for older versions of their OS and hardware. If users do not want to switch to new systems, they might turn to lightweight Linux distributions that support older machines (like Xubuntu).

4. Alpha Version of Asahi Linux Supports Apple Silicon, More to Come

With Intel transitioning to Apple Silicon processors, the only viable OS choice for Mac hardware became macOS. Asahi Linux decided to create a Linux distribution for Apple Silicon processors. In December 2022, Asahi Linux announced support for GPU, which was a significant breakthrough.

Asahi Linux will make it easier for other developers to port Linux to Apple Silicon. The project could become a viable alternative to macOS. In short, Linux is occupying even a larger niche on Macs than on Windows.

As it was during the PowerPC and Intel eras, Linux on Apple Silicon will likely appeal to developers and tech personnel rather than the general Apple user base. The release of the first alpha version of Asahi Linux has already happened.

5. Linux Gaming Continues to Grow

Despite games on Linux still being far from mainstream, interest in this platform is growing. Steam statistics show a slow but steady increase in the number of users who use Linux on their gaming PCs.

According to Valve’s survey of their customers’ hardware and software, it seems that Linux gaming is developing organically, albeit slowly. For instance, many original games are available on Steam for Linux. With Proton, gamers can switch to Linux without giving up their old favorites.

Enter Steam Deck, the portable Linux-based gaming console introduced by Valve. This device has already created quite a buzz. If Steam Deck becomes a successful project, developers might consider releasing native Linux games before Windows versions. Or at least make Linux ports a priority.

6. Running Windows Programs on Linux Is Getting Easier

With WinApps, you can easily manage and run Windows software on Linux and even integrate it into your system and context menu. Wine helps run Windows programs on Linux seamlessly. How does it work? Simply put, Wine translates Windows internal commands into commands your Linux system can understand.

There are quite a few projects for running Windows applications on other platforms based on Wine:

• CrossOver: A significant portion of Wine developers work on this project. The releases are more stable, the only main drawback is that CrossOver is paid.
• PlayOnLinux: This project is entirely based on Wine and is free. The program is also available for Mac (PlayOnMac).
• Bottles: A simple-to-use tool with various features. You can run both applications and games here.

And this is just the tip of the iceberg, so share your favorites in the comments.

7. Chromebooks Are Challenging Macs

Chromebooks are internet-focused laptops running a customized version of Linux. They have become a popular alternative to Windows and Mac laptops due to their low cost and ease of administration.

Many users have already experienced the benefits of Chromebooks and might not want to go back to a standard PC. With ChromeOS Flex, you can rejuvenate your old computers using the ChromeOS interface.

ChromeOS, and therefore Linux, poses a serious challenge to Mac as an alternative computing platform.

Google is also pushing towards cloud gaming with a new line of gaming-focused Chromebooks from many manufacturers. It remains to be seen how this idea will unfold in 2024, so stay tuned.

Partisanship and fanaticism aside, in today’s article we will talk about the pros and cons of each of these platforms, but always guided by the needs of the home user, who uses the computer to consume multimedia files, browse the internet, play games and even run some work, whether academic or professional. With this scope defined, corporate, infrastructure and embedded systems scenarios will be left out of this article, as each of these, by itself, would yield a separate individual article.

That said, let’s take a look at the three operating systems that dominate the domestic market today, pointing out positive and negative points of each of them, as well as indicating which usage/need scenarios each one is best suited for.

What you need?

It is not uncommon to hear from so-called experts that Windows is no good, that Linux is the most secure operating system of all and that macOS, being from Apple , is too expensive. All these statements are very relative and need to be very, very considered by the user when buying a new computer or opting for a new operating system to use on an old PC, otherwise it is almost certain that you will be dissatisfied with the choice you have made. others did for you. So let’s get to the question everyone should ask anyone looking to buy a new computer: what do you need? After defining very well what you will use this computer for, you need to think about how much you are willing to pay and try to balance everything on the cost-benefit scale to arrive at the ideal configuration that fits your budget.

Made it up? So it’s important to know one thing: there is no perfect operating system. Almost always a very good feature of one of them will be lacking in the other and vice versa, which is why it is important to know exactly what your expectations are with your computer to understand what Windows, Linux and macOS can offer and do for you Take the following into consideration: although many people complain that Windows is paid for, the truth is that most of the time the cost of the license is “built in” to the value of the new computer and you will hardly have to pay for it “outside”. macOS, in turn, is free, but limited to Macs (we’ll talk about their price later). Linux, finally, is completely free, regardless of platform, but it may lack some features you need. Of course, this first explanation is very simplistic, but it helps you keep in mind that it is very important to know what your needs are and what you need.

Windows

Windows has been the most popular operating system on the market for many years, currently being installed on around 78% of all computers in the world . The number is impressive and, in part, is a consequence of the aggressive adoption policy that Microsoft has prepared for Windows 10 since its launch in 2015.

The company’s idea was to offer a free upgrade to the new system for Windows 7 and Windows 8.1 users , which in itself was a huge incentive. Furthermore, Windows 10 arrived with the promise of correcting all the mistakes made by Windows 8, delivering a more fluid and consistent user interface, and being the “last” Windows released by Microsoft. In practice, we saw that this meant that the system became a service and is now periodically updated to receive new functionalities, resources, security fixes and the like — in other words, you don’t have to worry about when Windows 11 will come out or how much it will it will cost.

This whole strategy worked very well and today Windows 10 alone is installed on no less than 800 million computers around the world. Because of this, for many people the Microsoft system is the most obvious choice of all, but this change to software as a service has brought some problems to the platform

Therefore, the first analysis to be made is this: if your budget is very limited, then you will probably feel inclined to go with Windows or Linux. If your goal is to work with video production or graphic design, 3D modeling and the like, then a Mac may be worth the investment.

Containers: The Building Blocks

Containers are lightweight, standalone executable packages that encapsulate an application and its dependencies, libraries, and runtime components. Unlike traditional virtual machines (VMs), containers share the host operating system’s kernel, making them incredibly efficient and portable. Popular containerization technologies like Docker have gained widespread adoption due to their ability to provide consistency across different environments.

Benefits of containers:

1. Isolation: Containers offer high isolation, ensuring an application runs consistently, regardless of the underlying infrastructure. This isolation enhances security and reliability.
2. Portability: Containers are platform-agnostic, allowing developers to create applications once and run them anywhere, whether on a developer’s laptop or a production server farm.
3. Efficiency: Containers are lightweight and quick to start, making them ideal for microservices architectures, where numerous small services must scale rapidly in response to changing demands.
4. Resource Utilization: Containers share system resources efficiently, enabling multiple containers to run on the same host without conflicts or resource wastage.

Orchestration: The Control Center

Container orchestration is automating containerized applications’ deployment, scaling, and management. It acts as the control center for managing containers at scale. Kubernetes, an open-source container orchestration platform, has emerged as the de facto standard in this domain.

Kubernetes provides a robust framework for orchestrating containers. It offers features like automated load balancing, self-healing, rolling updates, and scaling, essential for managing complex applications in dynamic environments. Kubernetes abstracts the complexities of managing individual containers, allowing developers and operators to focus on higher-level tasks.

Benefits of orchestration:

1. Scalability: Orchestration platforms like Kubernetes can automatically scale application instances up or down based on real-time traffic, ensuring optimal resource utilization and high availability.
2. High Availability: With features like self-healing, orchestration platforms help maintain application availability by detecting and recovering from failures.
3. Rolling Updates: Orchestrators enable seamless updates and rollbacks of applications, reducing downtime and risk during deployment.
4. Resource Management: Orchestration platforms monitor and manage resource allocation, preventing contention and ensuring consistent performance.

Integration with Modern Operating Systems

Containers and the OS Kernel

Containers rely on the host operating system’s kernel for their execution. This close integration allows containers to be incredibly lightweight and efficient. However, it also means that the host operating system must support containerization features. Modern Linux distributions have embraced containerization by including kernel features like namespaces and groups, essential for container isolation and resource control.

Security Considerations

While containers offer isolation, their security is only as strong as the underlying operating system. Vulnerabilities in the OS kernel can impact all containers running on the same host. Therefore, keeping the host operating system updated with security patches and best practices is crucial.

Additionally, container images must be regularly scanned for known vulnerabilities, and security policies should be implemented to restrict container privileges and network access, further enhancing the overall security posture of containerized applications.

Orchestration’s Role in OS Management

Container orchestration platforms like Kubernetes extend their reach beyond just managing containers. They also play a crucial role in managing the underlying infrastructure, including the host operating systems. Here’s how orchestration platforms contribute to OS management:

1. Automated OS Updates: Orchestration platforms can automate applying OS updates and patches. This ensures that the host operating systems remain secure and up to date without manual intervention. This is particularly important for large-scale deployments where updating each host individually would be impractical.
2. Node Maintenance: Orchestration platforms facilitate node maintenance operations, such as draining a node before performing maintenance tasks. This ensures running containers are gracefully moved to other nodes, minimizing application disruptions.
3. Kernel Patching: Keeping the host OS kernel up to date is vital for security. Orchestrators can coordinate kernel updates and ensure that all nodes in a cluster are running the latest secure kernel version.
4. Resource Management: Orchestrators monitor resource usage at the node level, allowing operators to identify and address resource bottlenecks or contention issues. This granular control ensures that applications run smoothly without impacting the stability of the host OS.
5. Node Scaling: When resource demand increases, orchestrators can automatically provision new nodes to distribute the container workload effectively. Once the nodes are added, they can be seamlessly integrated into the cluster and managed alongside existing nodes.
6. Hardware Abstraction: Orchestration platforms abstract hardware differences across nodes. This means that applications can be deployed uniformly across various hardware configurations without needing custom configurations for each node.

Conclusion

Containers and orchestration have redefined how we build, deploy, and manage applications in modern operating systems. They offer benefits such as portability, scalability, efficiency, and automation, making them indispensable tools for developers and operators. As technology advances, the role of containers and orchestration in shaping the future of operating systems is set to become even more significant. Understanding and harnessing these technologies is essential for staying competitive in the rapidly evolving software development and deployment world.

In summary, containers and orchestration are not just buzzwords but the foundation of modern computing, driving innovation and efficiency in operating systems.

Mainframes: The Birth of Operating Systems

Mainframes, the giants of early computing, marked the inception of operating systems. These colossal machines were the size of small rooms and required highly specialized knowledge to operate. In the 1950s, systems like the IBM 704 and UNIVAC I relied on rudimentary operating systems to manage tasks such as input/output operations and memory allocation.

As computing needs grew, the demand for more advanced operating systems became apparent. The introduction of IBM’s OS/360 in the 1960s was a significant milestone. It brought about a level of compatibility and standardization previously lacking, making it easier for software developers to create applications for various mainframe systems.

The Rise of Personal Computers and Desktop Operating Systems

The 1970s and 1980s witnessed the advent of personal computers (PCs), revolutionizing the computing landscape. With the introduction of systems like the Apple II and the IBM PC, desktop operating systems became necessary. Microsoft’s MS-DOS, an early text-based OS, dominated the market during this era. Users interacted with PCs primarily through command-line interfaces, typing text commands to perform tasks.

The breakthrough came with the release of Windows 3.0 in 1990, which introduced a graphical user interface (GUI) and paved the way for user-friendly computing. GUI-based operating systems like Windows and Apple’s Mac OS (later macOS) made computers more accessible to a wider audience. The use of icons, windows, and a mouse made tasks as simple as clicking and dragging, setting the stage for a new era of computing.

To familiarize yourself with classic computer hardware, you can explore https://play-fortune.ro‘s collection of vintage gambling games from the early PC era.

The Internet Age and Networked Operating Systems

As the internet became an integral part of our lives, operating systems had to evolve to accommodate online connectivity demands. Operating systems such as Windows 95 and later versions incorporated built-in networking support, making connecting to the World Wide Web more accessible.

Unix-based operating systems gained popularity during this time, especially in server environments. Linux, an open-source Unix-like OS, emerged as a powerful contender and remains a staple in server rooms worldwide.
