Linux is? Explains Everything About Linux OS Linux has long been the base operating system of nearly all commercial networking devices, and today it has become the mainstay of enterprise infrastructure.
Linux is an open-source operating system that was tried and released in 1991 for computers, but has now expanded its use to support systems for cars, phones, web server and also for network equipment.
Linux has been an operating system that has long been present in this world, thanks to its maturity, and its security has made linux one of the most trusted OS available today, meaning it is ideal for commercial networking devices as well as enterprises looking to use it and peripherals to customize their own network and data center infrastructure.
With so many companies interested in linux, it has resulted in many people having Linux skills being sought after by the hiring managers of today’s IT companies. For example, many new technologies related to DevOps, such as SDN containers, infrastructure, and controllers, are built on Linux.
What is Linux, Linux is an open source or open source operating system similar to unix that is free to use for both personal and corporate needs, as we will see, linux was not actually derived directly from Unix. Like most Unix-like OS, Linux is made up of several components.
It is the core of the system and sends instructions to the CPU, peripherals, and memory.
The process that regulates system boot. On a computer, the user will recognize this with a rising splash screen. On the network device there is a status indicating the boot process.
Background service that is started at boot time or after the system is fully running. For example, the network daemon activates all network interfaces at boot. Other daemons are things like time and DNS.
This is the Linux command line or what is often referred to as the Command line interface. This can be especially difficult for people who are used to working in a graphical or desktop environment, but for most users who are network professionals, they are used to operating in the shell or command line.
The command line interface (CLI) of the shell offers a number of powerful capabilities – including those essential for system and network administration – for advanced users accustomed to text-based interfaces.
Linux desktop environment
Outside of the shell, there are a number of desktop environments for Linux, which function much like the window-based GUI we often use in Windows and macOS operating systems. Unlike other operating systems, Linux is also equipped with one of the many desktop environments to meet the needs and tastes of users so that users feel as familiar as when using the Windows operating system or Mac OS.
History of Linux
History records that Linux is one of the many operating systems that fall under the “Unix-like” heading. The history of Unix itself is very bleak. But Linux, although it gives off a lot of the feel of Unix, doesn’t actually reuse Unix source code.
Linux can actually be considered the grandson of Unix. Its predecessor was MINIX, a small Unix-like OS created in the late 80s to illustrate students’ operating system design principles.
MINIX code is available for educational purposes but cannot be reused for commercial applications. In 1991, 21-year-old computer science student Linus Torvalds announced that he would create a new operating system, inspired by MINIX but written from scratch so that the code could be released as open source under the GNU GPL. He combined the name MINIX with his own name and dubbed his new operating system Linux.
The Linux kernel is the core of the operating system. It also represents a major difference between Linux and MINIX (which is somewhat ironic, since Torvalds was accused of stealing code from MINIX to create its OS). Whereas MINIX is based on a microkernel which contains the minimum amount of code required to run an operating system, Linux has a monolithic kernel, meaning that functions such as the file system, virtual memory, and various system calls all occur in the privileged kernel space.
One of the advantages of the kernel, which is also one of the main advantages of Linux as a whole is that the internal workings of the OS can evolve over time, the interface between the kernel and the user space – the part of the system on which individual applications run can remain very stable, so when you upgrade Linux will not force you to upgrade your software.
Because Linux is an open source operating system aka open source, this code is released under the permissive GNU Public License. It means:
- The Linux operating system can be downloaded and installed for free.
- Administrators can study the OS freely and customize it as needed.
- There are unlimited redistribution rights over the original or modified versions of the operating system.
One of the clearest signals that Linux is a community-based project is that the kernel is managed not in secrecy in the company lab but through a public e-mail list, where all proposed updates and the debate about whether they should be adopted into the operating system are available for anyone to see. . Anyone can join the Linux community by participating and contributing to this mailing list.
The Linux community develops not just the kernel, but the whole. And because of the open nature of linux, it means there is a large group of professional users who are experts and hobbyists who are actively involved in finding new ways to make Linux even more powerful. For example, the linux containner has largely evolved through the involvement of various developers around the world.
And Linux as a community project doesn’t mean a Linux-based platform is an “inferior” device. Linux has an excellent ecosystem with mature APIs as well as an agile network stack optimized for modernized data centers.
Because Linux is open source, there are no vendors selling it; theoretically, you can download the kernel, desktop environment and various other utilities and applications, and install them yourself. In practice, these OS components are packaged together and are called distributions or what we often refer to as distributions. Basically, Linux OS transforms in certain ways that’s ready to use out of the box.
Again, in theory anyone can put Linux together, but most of them are offered by companies and non-profit organizations. Commercial distributors may charge a fee for their distribution, or offer an optional paid support service. Some of the very popular Linux distributions are:
- Red Hat
- Oracle Linux
- Arch Linux
The list is always changing, DistroWatch keeps track of the major players and assesses the pros and cons of each. If you want to choose a linux distro according to your needs, you can also check out my previous article on → 10 best Linux OS distributions to suit your needs.
Linux vs Windows
Linux is an OS that is truly stable and problems very rarely occur, in contrast to Windows where we often encounter many problems and bugs. However, existence Windows for the desktop it cannot be replaced by the presence of many Linux distributions that have released a desktop version. This is actually because users are very familiar with Windows and even school subjects are taught to use Windows. In addition, Windows also has a lot of software and games that support it, this is what makes Windows a lot of users and of course Windows is easier and more familiar to all users around the world.
But when it comes to server operating systems. Then Linux is the champion. Linux is widely seen as a major player in the server market on par with Microsoft and other vendors, and even though linux is the top choice over other OSs, there are many too. Linux server distro which is very popular in vogue. And in the most lucrative tech marketplace to emerge of this century, Linux is, in a sense, completely crushing Redmond. OS Android smartphone built on linux and it dominates the smartphone market and is loved by many users than made by microsoft. Android is the top player in the mobile market, although Microsoft has tried many times, they still fail to gain popularity in this market. So, Windows is superior in desktop computer market while Linux wins in server and smartphone market.
