Linux

Learning to program is both fun and easy by taking this brand new and exciting Introduction to Programming for Non-Programmers course! Not only will you learn the foundations of how to program, but you’ll also gain a solid foundation in the world’s most popular computer language: JavaScript.  Without having to install any special software, and using only your web browser and your text editor, you’ll journey into the exacting world of programming. Using an easy to learn training style, you’ll learn about the JavaScript language, functions, variables, making decisions, looping, and more. At the end of the course, you’ll be in a great position to take other introductory programming language course.

The only prerequisite is a basic familiarity with computers, along with an eagerness to learn programming. You do not need any programming experience.

This course provides a fundamental understanding of the functions within any modern operating system. Most users of computers, like Windows 10 or Redhat V8, only deal with the GUI (graphical user interface). This course explores the functions used by those GUIs and provides an understanding of what is really happening. Used either stand-alone to gain a basic understanding of operating system concepts or with a companion textbook, Modern Operating Systems by Andrew S. Tanenbaum, while viewing the course or as a resource for later reference, this course provides a solid foundation that would enhance understanding for other courses, such as USB 2.0 Architecture Part 1, Oracle 12c Real Application Clusters Part 2: Performance Tuning, Administration and Backup, PCI Express (PCIe) Overview, Cloud Computing Foundation, and any programming course.  This course is a pre-requisite for the Linux V7 Essentials course.
