When it comes to operating systems, MAC and Linux are often pitted against one another. Long-standing users of either system will stand by their respective pick, but which one ultimately reigns supreme? We aim to answer this question with an in-depth analysis of each system’s addressing table. An addressing table, or page table, consists of a data structure that is used to store information about which regions of memory are occupied. This table is essential in order to allow a processor to understand and process instructions from memory. As you can imagine, it is an important aspect to consider when analyzing the performance of an operating system. Let’s start with the MAC OS addressing table. It is a hierarchical structure...

TTY (teletype), also known as console or text-only terminal, is a program running on Linux that allows users to connect to a remote server and execute a shell session with a text-based interface. First introduced into Internet Relay Chat (IRC) in the mid 1980s’, TTY has been widely used in Linux operating system ever since. The magic of TTY lies in its flexibility to handle various tasks. It can be used to manage remote servers, carry out commands, monitor important logs, exchange files and even issue diagnostics. For system administrators, TTY provides an efficient way to work with remote systems and manage system processes. Using TTY, administrators can access their systems directly through SSH (Secure Shell). SSH allows users to...

Linux is widely considered to be the best operating system among open source and free softwares. It is also popular among system administrators, developers, networking and security professionals. If you are looking for an introduction to Linux, then the book “Mastering Linux for System Administrators” is an ideal choice for you. “Mastering Linux for System Administrators” is a comprehensive guide to the most important aspects of Linux system administration. Written by experienced Linux professionals and veterans of the Linux community, the book covers all the fundamentals of Linux system administration, from the installation and configuration of applications to the advanced administration of a multi-server environment. The book has been carefully structured to make it easy to follow and learn. It...

When those in the Linux environment plan to store their data, the choice is often hard disk drives (HDD), flash drives (SSD) or persistent media platforms like fibre channel drives (FC). Fibre channel technology has long been utilized by datacenters and IT shops to move storage among servers. Longer storage life, greater storage capacities, and functions such as data replication, keep fibre channel a viable choice. Fibre channel provides several key advantages over traditional storage solutions, especially in the Linux environment. First, a fibre channel network provides a great deal of speed. This is because the data is broken up into small chunks and sent over the network at the same time, which helps to reduce latency. Moreover, fibre channel...

Linux Ukey, for short, is a powerful and versatile tool for computer users who need to secure their system access. It is one of the most important security measures for enterprises around the world. With Linux Ukey, system administrators can lock down their systems from unauthorized access with a combination of strong passwords, encryption and digital signatures. Linux Ukey uses a special key file, which is stored in a secure environment and is used to access the system. The key file has a special combination of characters which are stored within the key file. These characters are linked to a particular user and is used to authenticate the system access. In order to make the user authentication process secure, encryption...

Configuring Linux Keyboard Settings Configuring keyboard settings in Linux is an important virtual task and can be done in a variety of ways. Keyboard settings contain the keyboard layout, keyboard language, keyboard shortcuts, and other settings. This guide will walk through the various methods of configuring these settings. First, you can set the keyboard layout by modifying the Xorg keyboard configuration file. This file is typically located in the/etc/X11/xorg.conf.d/ directory. To configure the keyboard layout, you would use the InputClass section of the file and add the following lines: Section “InputClass” Identifier “keyboard” MatchIsKeyboard “on” Option “XkbModel” “your_keyboard_model” Option “XkbLayout” “your_keyboard_layout” EndSection Once the model and layout have been set, you can then set the layout language. This is done...

If you’re going to be an effective Linux user, you need to know the art of deleting files like a pro. Deleting files is a very important task in Linux and requires a certain skill level. Fortunately, it’s an easy skill to learn and master. The first step to mastering the art of deleting files in Linux is to become familiar with the basics. In Linux operating systems, there is generally a command line interface (CLI) used for tasks like file management and editing. Using the CLI, users can create, edit, move, and delete files with the proper commands. In order to delete files in Linux, you need the command “rm”. This command is used to remove files from a...

Linux Branching is a common practice in software development, which allows users to easily switch between different versions of the same repository. Branching can help users find specific bug fixes or feature updates and much more. In this article, we will explore the various possibilities of Linux Branching and what it can offer developers and users. When branching on Linux, developers are able to pull from multiple repositories and create branches from them. By branching from a repository, developers are able to keep their code separated from the official repositories. Thus, developers are able to write code and test new features for specific versions and only when the time is right, merge the changes back into the main tree. This...

Linux is one of the most powerful and versatile operating systems available, particularly for engineers and developers. Inexperienced users may find it overwhelming to become familiar with using Linux for everyday tasks, but there are plenty of tools available to streamline the experience. Among these powerful tools is the ability to create and use aliases. Aliases are shortcuts that can be created in Linux to represent a specific command or set of commands. This makes it easy to access commands more quickly, and more importantly, improves your workflow. Rather than typing out a lengthy command each time you need to execute it, you can use a far simpler alias to reference the same command. Let’s go over the basics of...

Linux SACK Technology (Selective Acknowledgments) is a form of improved error control in Linux computer networks. It is commonly used to enhance communication between two hosts on a Linux networking. It helps in reducing the impact of sending lost packets on the overall performance of the network. Linux SACK technology is a component of the Linux TCP/IP protocol stack. This is used when a packet is lost in the network and the receiver of the packet needs to request an Acknowledgment (ACK) to inform the sender of the packet that the packet was received. The sender then responds with an ACK that includes a “sack” option, a data structure which contains a list of all packets received out-of-order. This technology...
