What is Linux Programming?

<p>Linux, like its predecessor Unix, is an open-source operating system kernel. Since Linux is protected under the GNU Public License, many users have imitated and altered Linux source code. Linux programming is compatible with C++, Perl, Java, and other programming languages. </p> <h3 id="section---ImportantFactsAboutThisFieldOfStudy">Important Facts About This Field of Study</h3> <p /> <table border="1"><tr><td> Degree </td><td> Linux Programming Certificate</td></tr> <tr><td> Online Availability </td><td> Online programs are available</td></tr> <tr><td> Common Courses </td><td> Linux installation, kernel programming, storage scalability and optimization</td></tr> <tr><td> Possible Careers </td><td> Computer programmer, software developer</td></tr> <tr><td> Median Salary (2021) </td><td> $93,000 (<i>for all computer programmers</i>)</td></tr> <tr><td> Job Outlook (2021-2031)</td><td> 10% decline (<i>for all computer programmers</i>)</td></tr> </table><p><i>Source: *U.S. Bureau of Labor Statistics</i> </p> <h3 id="section---HowLinuxWorks">How Linux Works</h3> <p>Linux is an operating system kernel that can be shared and distributed freely. An operating system is an interface that connects users to computer hardware and orchestrates the running of programs and applications. The kernel is the core of the operating system because it manages communications between software and hardware components. As a kernel, Linux handles the lowest level of abstraction, or the most complex and specific data. Information is not consolidated or simplified for user-friendliness. </p> <h3 id="section---WhatLinuxProgrammersDo">What Linux Programmers Do</h3> <p>Beginning Linux programming uses tools like the GNU compiler and debugger to create applications for data storage, the construction of graphical user interfaces, and scriptwriting. More advanced Linux applications let programmers develop Linux software, optimize existing programs, and write programs with complex features like multi-threading, multiprocessing, hardware device interaction, and inter-process communication. </p> <h3 id="section---UsesForLinux">Uses for Linux</h3> <p>Linux is widely used in servers, computer architecture, and computer security systems. It is also used in real-time programs and the embedded systems of cell phones and PDAs. Mozilla Firefox runs on Linux, as does the popular alternative operating system Ubuntu. Linux programming has resulted in many applications. The ways that programmers use the free source code of Linux are constantly evolving and adapting.</p>
