Introduction Data-center deployment involves the process of setting up computer systems and related components such as storage, networking, and software applications to support the running of business operations. It is critical for organizations to have a reliable, scalable, and secure data-center infrastructure to ensure continuity in their daily operations. Red Hat Enterprise Virtualization (RHEV) environment provides a robust platform for managing data-center resources efficiently. RHEV Environment uses Kernel-based Virtual Machine (KVM) hypervisor technology which provides virtualization services that allow multiple Operating Systems (OS) to run on the same physical machine without interfering with each other. The RHEV environment also ... Read More

Redis is an open-source, in-memory data structure store that can be used as a database, cache, or message broker. It is known for its high-performance and low-latency capabilities, making it a popular choice for real-time applications. On the other hand, Docker is a containerization platform that allows developers to package applications into containers that can run anywhere on any platform. Containers are lightweight, fast to deploy and have small footprints compared to traditional virtual machines. Preparing for Deployment Installing Docker on your machine Before you can deploy Redis in Docker, you'll need to install Docker on your machine. ... Read More

Introduction Linux is an open-source operating system, which is favored by many users for its robustness, flexibility and stability. One of the key features of Linux is its ability to provide users with better control over their system's resources. This is achieved through the use of the partitioning scheme, which divides a hard drive into multiple sections or partitions, allowing for more efficient use of space and resources. What a partition is in Linux? A partition in Linux can be thought of as a logical division or section on a hard drive that isolates data from other parts on ... Read More

Introduction The kernel is the core component of a Linux-based operating system, and it is responsible for managing the system's resources and communicating with hardware devices. Whenever a new version of a kernel is released, it typically includes important bug fixes, security patches, performance improvements, and other enhancements that can improve the overall functionality and stability of the system. However, when multiple versions of the kernel are installed on the same machine over time, they can take up valuable disk space and slow down system performance. Deleting old unused kernels is an essential maintenance task that helps keep your Linux-based ... Read More

No matter what device we are using, iCloud Drive makes it simple to access and share the files and folders we save. Some of the other features ... Read More

An operating system is in charge of controlling a computer system's resources and acting as an interface between the hardware and software. The management of events that arise during the execution of programmes is a crucial component of operating system design. Traps and interrupts are two often utilised methods for this purpose. A trap is a computer-generated occurrence that results from an error or exception in the programme that is running at the time. Division by zero, page errors, and illegitimate instructions are a few examples of traps. The CPU instantly enters kernel mode after a trap occurs and ... Read More

A software is a set of rules or instructions that are given to a computer to perform some function. Basically, software is classified into two types: Application software and System software. Application software is additional software in a computer which is used to perform a specific function. Users has a direct access to this application software and this software is not mandatory in a system. We can use system without this application software. System software is the main software of a computer that has a direct access to the system’s hardware. It takes care and monitors all the other ... Read More

An Operating System is a bridge between the software and underlying hardware. It is the first program that is loaded by BIOS when the computer is turned on. OS is stored in hard disk. It manages the overall components of the computer. OS executes all the other applications in a computer or any other devices. OS interacts with users with the help of CLI or GUI. It allows us to store and share data such as pictures, videos, etc. It performs high level operations. User can perform number of tasks at the same time. It is involved in file and ... Read More

Virtualization is the process of creating a virtual version of an operating system. It also creates virtual versions of servers, network resource etc., Generally, some applications don’t have the compatibility to run in a system. Using virtualization concept, this application can be made to run in the same computer. Virtualization breaks the system into multiple parts called virtual machines. The system on which virtualization is applied is known as a Host system and the OS is known as host OS. The virtual machines formed are known as Guest systems and their OS is known as guest OS. What is a ... Read More

A Firmware is a set of instructions or a block of code that is programmed in hardware devices. It instructs the hardware to perform its function when the call is made. Firmware is present in computers and electronic devices. Operating system is a software that sits in between the software and hardware of the computer system. It acts as a mediator and provides the interface to interact with them. Operating systems are used in computers, laptops, TV, mobiles, etc. What is a Firmware? A Firmware is a small code embedded in the hardware. They are modified software versions. The ... Read More
