Linux red hat is a Linux platform or a Unix-like OS family. Now Linux is the most popular operating system. SUSE Linux, Fedora Linux, Red Hat enterprises, CentOS, Ubuntu, and Turbo are some Linux distributors. Most leading Red Hat Enterprise is the developer of this. Also, it has discontinued the working state. As well as its source model is open source. Firstly, the Red hat was released on May 13 in 1995, 25 years ago. The latest release was considered 8.2 on April 28, 2020.

History

The first version was Version 3.0.3. It had a better linkage and administrative format. Ketan Bagal developed Anaconda graphical installer for this Linux red hat. A software library called Kudzu was introduced in Version 6. The Blue curve desktop theme is included in Version 8.0.

More Details

Features

A Linux distribution developed by Red Hat Inc. Mainly it focuses on the commercial market. So it has a Linux kernel type. However, it has various free software licenses. Further, provides property binary blobs. Usually uses Package Kit, Yum, and RPM package managers. GNOME Shell considers as the default user interface of this. Especially supports IBM Power System, IBM Z, x86-64, and ARM64 platforms. Importantly used for supercomputers, mainframe computers workstations as well as servers. Nowadays Linux red hat mange and conduct many of the software. And also it supports cloud, storage, middleware, automation, virtualization technologies.

 

Why should we use this?

Linux red hat is free and open-source. On the other hand, it works on several platforms. Always it has a very powerful security system and robustness. Because of that it does not exists viruses. However, it has widespread usage. The Linux kernel is distributed under GNU, which provides a free software foundation. Crashes or freezes are not existing in this platform is the most special feature.

 

Contrast

Difference between Fedora and Red Hat

Red hat is a commercial or corporative version based on projects of Fedora but Fedora is a general-purpose platform configured via the Linux OS kernel model. Fedora releases new versions about incrementally every six months but our main topic releases new versions according to the 12-18 schedule.

 

Difference between Oracle and Red Hat

Oracle Linux is distributed by Oracle cooperation. Though red hat has a GNOME default user interface oracle has both GNOME and KDE default user interfaces. Unlike the red hat, Oracle has GPL, GNU, and different kinds of licenses. Both oracle and red hat are using RPM packages. But oracle mainly applies to cloud computing and enterprises.

 

Ubuntu and Red Hat

The red hat has a CLI based system, so it is difficult to practice for novice users. But it is easy to use Ubuntu for novice users. Ubuntu has a large community and it is easy to use.

What is a Linux OS? Why Linux is so popular?

written by Bhagya

Linux Operating System(OS) is an open-source OS that can work across platforms. Also, we can install the Linux OS on computers, mobile phones, tablets, and laptops. This OS is based on Unix which is also another OS. Linux is been around for more than 30 years.

Why Use Linux OS?

One of the biggest reasons for using this OS is it comes free of cost. Also, the OS gives you protection from viruses, malware, and other threats that other OS cannot give you. This will save you money on additional security software. Also, user privacy is well respected by the Linux OS.

Unlike other OS, Linux provides certain services that you can install to your device easily. For example, to install a web server in Microsoft OS it takes a lot of time while it only takes a few commands to do it in Linux.

And the open-source help you run any programs for any purpose and learn how it runs. Also, you can modify the OS to suit your need and distribute the OS without any legal troubles. Linux also comes out with updates regularly and this helps fix small problems users face. Also, it’s easy to update the Linux when you compare them with other OS. Linux is also a lot more reliable than other OS where crashes and slowing are less common. Even in case of a crash, you will have a lot of community supports that will help you to fix it faster. The need for a reboot in a Linux system is rare. Linux is always trying to improve its user experience that will make the OS beginner-friendly.

Features of Linux OS

Linux has two types of interface, Command Line Interface(CLI) and the Graphical User Interface(GUI). The desktops and laptops mainly use the GUI. But, you can use the CLI which is a textbase command to do certain actions as well. Another, good thing about the Linux OS is it can run on devices with low-end hardware.

Linux also is a great OS for programming. One of the best perks of using this OS for programming is that it supports most of the languages we use for coding. Linux can support languages like Python, PHP, Java, and Ruby without any new installations. Also, this OS has other features that make coding easier with its terminal been better to code on than other OS. And the package manager along with libraries native to Linux makes the job easier.

Also due to better security and fewer crashes, Linux is used as the OS in many servers. Also, they have no downtime which is the reason why it’s is the best OS for servers.

Conclusion

Although the Linux OS isn’t as easy to use as the other OS for beginners, with time it gets easier. But its ability to give the user a secure and smooth service cannot be rival by any other OS. In conclusion, the services Linux gives outweigh its slight problems which makes it one of the best OS to work on.

What is an operating system ? ~ Why OS is so important ?

What is an operating system?

Everyone has heard the word called OS, of course, OS means Operating System. It is the manager of the computer, and also manages all the available resources on a computer from CPU, to memory, to hard disk. And also it is software. There are two types of software called system software and application software. Firstly the system software is a set of programs that coordinates activities and functions of the hardware and various other programs throughout the computer system. Also, there are different types of systems software include operating systems and utility programs.

Definition of Operating System

Definition

An operating system is a set of computer programs or a collection of software that manages and controls hardware resources. Also, an operating system act as an interface between application software and hardware. Especially, it gives common services for all computer programs. Of course, an operating system is the system software, and application software needs an operating system to fulfill its functionalities.

Examples

Windows XP, Windows Vista, UNIX, Linux, Mac OS are some examples of the operating systems. Indeed, Linux is a free and open-source operating system. Also, it works on several platforms and Linux never gets slow. Linux has widespread usage and no threat of viruses. Red Hat, Fedora, Ubuntu, SUSE, and Debian are some Linux examples.

Tasks of the operating system

The operating system manages and controls all the parts of computer and hardware resources. Similarly, it runs applications include word processors, web browsers, games, etc. It manages all data and files on your computer. Also, it helps to organize your computer by doing many things to data like a copy, move, delete, rename, and cut. The operating system acts as an intermediary between the user and computer hardware too. Performing common computer hardware functions, providing a user interface and input/output management, providing a degree of hardware independence, managing system memory, managing processing tasks, providing networking capability, and controlling access to system resources are some other major tasks of an operating system. Certainly, the operating system acts as a coordinator which mange all resources and prevents errors and improper use of the computer such as connection failures in the network, power failures, lack of paper in the printer, and so on.

Main functions

The first and foremost function is providing a user interface. Especially it allows individuals to access and interact with the computer. There are two types of user interfaces. The first one is a command-based user interface that requires text commands to be given to the computer to perform basic activities (e.g. DOS). The other is a graphical user interface (GUI). GUI uses pictures and menus that are used to send commands to the computer system (e.g. Windows and Mac OS). The second main function is hardware independence that provides hardware independence for application software. Application software interfaces with the operating system which interfaces with the hardware. When the hardware changes, the operating system changes so that the application software is not required to be changed. The other main function is the operating system act as a facilitator. It provides standard libraries and makes application programming easier and faster.
