LINUX: Open Source Operating System (OS).

The first course in a 2-part series prepares you for expert in linux Administration.



What Is Linux?

Linux® is an open source operating system (OS). An operating system is the software that directly manages a system’s hardware and resources, like CPU, memory, and storage. The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work.

Linux has been around since the mid-1990s and has since reached a user-base that spans the globe. Linux is actually everywhere: It’s in your phones, your thermostats, in your cars, refrigerators, Roku devices, and televisions. It also runs most of the Internet, all of the world’s top 500 supercomputers, and the world’s stock exchanges.

Scope Of Linux:

With the prevalence of Linux across so many technology areas though, you can take your Linux knowledge and apply it to roles like DevOps engineer, cloud architect, network administrator, security engineer, backend developer, frontend developer, data scientist, and much more.

The various job positions that require Linux skill are as follows: Linux Administration. Security Engineers. Technical Support.



Why Use Linux?

This is the one question that most people ask. Why bother learning a completely different computing environment, when the operating system that ships with most desktops, laptops, and servers works just fine?

To answer that question, I would pose another question. Does that operating system you’re currently using really work “just fine”? Or, do you find yourself battling obstacles like viruses, malware, slow downs, crashes, costly repairs, and licensing fees?If you struggle with the above, Linux might be the perfect platform for you. Linux has evolved into one of the most reliable computer ecosystems on the planet. Combine that reliability with zero cost of entry and you have the perfect solution for a desktop platform.

If zero cost isn’t enough to win you over–what about having an operating system that will work, trouble free, for as long as you use it? I’ve used Linux for nearly 20 years (as both a desktop and server platform) and have not had any issues with ransomware, malware, or viruses. Linux is generally far less vulnerable to such attacks. As for server reboots, they’re only necessary if the kernel is updated. It is not out of the ordinary for a Linux server to go years without being rebooted. If you follow the regular recommended updates, stability and dependability are practically assured.

Open source

Linux is also distributed under an open source license. Open source follows these key tenets:

  • The freedom to run the program, for any purpose.
  • The freedom to study how the program works, and change it to make it do what you wish.
  • The freedom to redistribute copies so you can help your neighbor.
  • The freedom to distribute copies of your modified versions to others.


Advantages Of Linux:

Open Source

One of the principle favorable circumstances of Linux is that it is an open-source working framework for example its source code is effectively accessible for everybody. Anybody equipped for coding can contribute, adjust, improve and circulate the code to anybody and for any reason.

Security

The 400-251 associated certification is CCIE security. This certification validates experts who have the knowledge and skills to architect, engineer, implement, troubleshoot, and support the full suite of Cisco security technologies and solutions using the latest industry best practices to secure systems and environments against modern security risks, threats, vulnerabilities, and requirements.

Restore More Established Pc Frameworks

Linux causes you to utilize or use your old and obsolete PC frameworks as a firewall, switch, reinforcement server or document server and some more. There are numerous appropriations accessible to use as indicated by your framework capacity. As you can utilize Puppy Linux for low-end frameworks.

Programming Updates

In Linux you experience a bigger number of programming refreshes. These product refreshes are a lot quicker than refreshes in some other working framework. Updates in Linux should be possible effectively without confronting any significant issue or concern.

More Resources

If you’re looking for one of the most reliable, secure, and dependable platforms for both the desktop and the server, look no further than one of the many Linux distributions. With Linux you can assure your desktops will be free of trouble, your servers up, and your support requests minimal.
