What is Booting? Booting is a process of starting a computer or computer like device such as a smartphone, etc. Therefore, booting of a computing device start when we press the power button of the device, it makes the computer or the device ready for use. Actually, when a computer or any computing device is switched off, its operating system remains in the secondary memory like hard disk of the system. But for execution of a software, it must be in the main memory of the system. Hence, booting may also be defined in other words as, the process of ... Read More

When a computer or any other computing device is in the powerless state, its operating system remains stored in the secondary storage like Hard Disk or SSD. But, when the computer is started, the operating system must be present in the main memory or RAM of the system. When a computer system is started, there is a mechanism in the system which loads the operating system from the secondary storage into the main memory or RAM of the system. This is called Booting process of the system. There are two types of booting depending on the number of operating systems ... Read More

In computers, when multiple threads of a process are executed independently by sharing the same resources, it is called multithreading. Read through this article to learn the benefits of multithreading in operating systems. What is Multithreading in OS? In computers, a program in execution is referred to as a process. When a larger process is sub-divided into smaller processes, then each sub-process is termed as a thread. Technically, a separate execution path within a computer program is called a thread. In simple words, a thread is a light-weight process that can be scheduled by the operating system and executed by ... Read More

Operating Systems are a type of system software that make the hardware functional and create the interface between the user and machine. Several types of operating systems available such as batch operating system, multiprocessing operating system, multiprogramming operating system, distributed operating system, etc. Batch Operating System The type of computer operating system which involves batch processing of tasks or jobs is referred to as batch operating system. This type of operating system was very popular in the 1970s. In the case of batch operating system, a single computer is used to process several tasks grouped in a single unit. In ... Read More

Windows Operating System Windows Operating System is a type of operating system based on Graphical User Interface (GUI). It is called a graphical user interface because it create an interface (communication screen) between user and machine by using graphical elements like icons, pictures, colors, etc. The Windows operating system was developed by Microsoft Corporation, an American Multinational technology company founded by Bill Gates and Paul Allen. Windows operating system is one of the most popular computer operating systems in the world. The primary reason behind its global popularity is its very user-friendly interface. Windows operating system also provides multitasking capabilities, ... Read More

Context switching is an essential aspect of modern operating systems that enables them to efficiently manage resources available to them. Context switching is process of switching from one process to another in a multi-tasking environment. operating system does this by saving state of current process and loading state of next process. Monitoring context switches in Linux is a crucial task for system administrators, developers, and users who want to optimize performance of their systems. In this article, we will explore how to monitor context switches in Linux and why it is essential to do so. Understanding Context Switching in Linux ... Read More

Introduction Dynamic Link Libraries, also known as Shared Libraries, are collections of compiled code, data, and resources that can be loaded and executed by an application at runtime. Shared libraries are commonly used in development of Linux applications, and are an integral part of x86 architecture. In this article, we will explore process of linking with x86 shared libraries on Linux x64 systems. Understanding x86 Shared Libraries An x86 shared library is a file that contains compiled code, data, and resources that can be shared among multiple applications at runtime. Shared libraries are loaded into memory only when required by ... Read More

In recent years, touch technology has become increasingly popular, with smartphones, tablets, and laptops offering capability to interact with devices by simply tapping or swiping screen. However, what if you could use touch technology on your computer using a USB device? This is where concept of multi-touch enabled USB devices comes into play. In this article, we will explain what multi-touch enabled USB devices are, how to make a USB device multi-touch enabled, and provide examples of popular multi-touch USB devices in market. What are Multi-touch Enabled USB Devices? Multi-touch enabled USB devices are peripherals that are connected to a ... Read More

Introduction In Linux programming, use of wide character strings is becoming increasingly common. Wide character strings, or wstrings, are a sequence of wide characters, each of which can represent a single Unicode character. This makes them particularly useful when working with text that includes characters from a wide range of languages, as well as text that includes special characters such as accents, symbols, and emojis. In this article, we will explore how to use wstrings in Linux APIs, with examples and explanations. What are wstrings and why use them? A wide character string, or wstring, is a sequence of wide ...

Introduction DBus is a widely used message bus system that facilitates communication between different software applications on Linux operating systems. It is used for inter-process communication (IPC) and allows applications to communicate with each other, even if they are running in different contexts. However, it can be difficult to determine which application or process is calling a specific DBus API. In this article, we will explore different methods for identifying caller of a DBus API on Linux. What is DBus? DBus is a message bus system used for inter-process communication (IPC) in Linux systems. It is a low-level, asynchronous protocol ... Read More
