Numerics are essential for understanding the complex facets of disc storage since they offer a hands-on, practical method to grasp fundamental ideas. We may investigate how disc capacity, performance, and utilization are estimated by delving into numerical examples, helping us to understand the fundamentals of efficient storage management. Example − Think of a cloud service provider, for instance, that provides its customers with access to file storage. The service provider stores customer files, including documents, photos, and multimedia content, on disc storage. The disc storage system is built to support high data throughput and offers reliable file access. In this article, ... Read More
The Nucleus is an RTOS that was developed by Mentor Graphics Embedded Software Division, a Siemens Business that supports 32-bit and 64-bit embedded system platforms. The Nucleus operating system (OS) is mainly intended for use in real-time embedded systems in medical, aerospace, industrial, consumer, and Internet of Things (IoT) applications. In this article, we will explore Nucleus Operating System, its components, and features as well. Nucleus Operating System The Nucleus OS was initially introduced in 1993. The latest version, 3.x, offers various features, including 64-bit support, safety certification, power management, and a process model. It also supports heterogeneous computing ... Read More
The NTFS file system used by Windows operating systems includes NTFS (New Technology File System) junction points. In essence, junction points are a kind of symbolic link that lets you join one directory to another inside the same file system. In this article, we will explore NTFS Junction Points, it’s architecture diagram, their use cases, example code in C#, and their benefits as well. NTFS Junction Points The main purpose of junction points is to build directory-level links, which let you change the path's destination to another location on the same volume. This can be helpful in a variety ... Read More
Concurrent programming employs the notion of lock variable synchronization to make sure that several threads or processes can safely access shared resources without coming into race situations or inconsistent data. It offers a mechanism to manage the order in which threads or processes are executed, enabling them to have exclusive access to shared resources when required. In this article, we will explore the mechanism of lock variable synchronization, use cases, and an example code snippet in C as well. Lock Variable Synchronization Utilizing a shared variable, often known as a lock or mutex (short for mutual exclusion), to ... Read More
In Python, file-handling tasks like opening, reading, writing, and closing files, or manipulating data in files are a common occurrence. While opening files has its significance and utility, it's equally important that files are closed properly to release system resources and to ensure that data integrity is maintained. In this article, we will explore different methods and techniques to close multiple opened files in Python, permitting you to optimize your file-handling operations and maintain clean code. Making Use of a Context Manager In Python, context managers are a tool for efficiently managing resources that need to be properly ... Read More
File permissions in Python empower you to determine who can perform certain operations on a file. These file attributes include read, write, and execute permissions. The os module in Python, especially the os.chmod() function in the os module, is used to set or modify permissions. The os.stat() function belonging to os module can be used to check the current permissions of a file. Managing and manipulating file permissions is important and critical for security and access control in Python programs. Checking file permissions in Python is important for ensuring the security and integrity of the data stored in files. ... Read More
When interacting and working with files and directories in Python, it often becomes necessary to check their permissions to determine and know what operations can be performed on them. Using the os module, you can conveniently check the permissions of a directory in Python. In this article, we will explore the topic of checking directory permissions and accomplish this task in a graded manner, using code examples for understanding the concepts along the way. Before we begin, you better ensure that you have a basic understanding of Python concepts and have Python installation on your system. Checking Directory ... Read More
An operating system (OS) is a piece of software that controls and manages the hardware and software resources of a computer while also giving users a simple way to interact with the system. By serving as a conduit between the user and the computer hardware, it makes it easier for different system parts to coordinate and communicate with one another. In this article, we will explore different operating systems along with their latest versions and features as well. Top Operating Systems Today's systems use a variety of operating systems. Here are a few of them − macOS Microsoft Windows ... Read More
In this problem, we will find each word of the string which comes after all words of the ‘words’ array. The first approach to solve the problem is to split the string into words and match elements of the words[] array with the string words. If we find words[] array’s element in the same order inside the string, we print the next word of the string. Another approach is to create a string of all elements of the words[] array. After that, we can find that string as a substring in the alpha string. If we find it as a ... Read More
In this problem, we will find the string of length equal to the given string so that when we sum both strings, we get the palindromic strings. Here, we can find another string such that the sum of both becomes 99999…, the largest palindromic string of the same length. If the given string starts with the ‘9’, we can find another string such that the sum of both becomes ‘11111…’. Problem statement – We have given a num string containing the numeric digits. We need to find the numeric string of the same length without leading zeros so that ... Read More
