Linux-RHCSA
Linux is, in simplest terms, an operating system. It is the software on a computer that enables applications and the computer operator to access the devices on the computer to perform desired functions.
One of the most noted properties of Linux is where it can be used. Windows and OS X are predominantly found on personal computing devices such as desktop and laptop computers. Other operating systems, such as Symbian, are found on small devices such as phones and PDAs, while mainframes and supercomputers found in major academic and corporate labs use specialized operating systems such as AS/400 and the Cray OS.
Linux, which began its existence as a server OS and Has become useful as a desktop OS, can also be used on all of these devices. From wristwatches to supercomputers, is the popular description of Linux' capabilities.
With a rise in mobile computing & various internet applications, the demand for professionals with an exposure to Linux/ Unix based platform development of applications on open source environment is high.
Linux uses both the graphical interface and command line, covering the major Linux distribution families.
Linux powers 94% of the worlds supercomputers, most of the servers powering the Internet, the majority of financial trades worldwide and a billion Android devices. In short, Linux is everywhere. It appears in many different architectures, from mainframes to server to desktop to mobile and on a staggeringly wide variety of hardware.
