Both paging and swapping are important concepts in operating systems that place a process in the main memory for its execution, but they are quite different from each other in many aspects. Read this article to learn more about paging and swapping and their specific characteristics. What is Paging? In OS, Paging is a memory management strategy in which the process address space is divided into blocks of the same size, called pages (where the size of each page is power of 2, and is between 512 bytes and 8192 bytes). The size of the process is then measured in ... Read More

In this post, we will understand the difference between Linux and Windows Operating System.LinuxIt is an open-source operating system.It is free.The file names are case-sensitive.A monolithic kernel is used in this operating system.It is more efficient in comparison to Windows OS.A ‘forward slash’ is used to separate the directories.It provides higher level of security in comparison to windows.It is widely used by programmers, mostly for developmental, gaming, and hacking purposes.WindowsIt is proprietary software, i.e. it is not open source.It is expensive.The file names are case-insensitive.A micro-kernel is used in Windows OS.It is less efficient in comparison to Linux.A ‘back slash’ ...

When you run an application inside a Docker Container, by default it has access to all the root privileges. You might have noticed that when you open an Ubuntu Docker Container Bash, you are logged in as the root user by default. This can prove to be a major concern in terms of security of the application. Any outsider can misuse this and hack the entire Container along with all the other files and applications running inside the Docker Container. Hence, it becomes very important to perform most of the trivial operations as a non root user wherever possible.In this ... Read More

One of the most important features of Docker Containerization is that it creates a bounded environment for running the Application with all the necessary dependencies and packages installed. Most applications require a backend database to store data points. Oracle provides Docker Images for running MySQL inside Containers and thus it becomes an excellent choice for testing your database applications. It provides lightweight MySQL Image instances with cleanup features once your testing is completed.Docker allows you to download the Image containing the MySQL binaries and dependencies and creates a virtual filesystem. Note that if you start a Docker Container with the ... Read More
