An Overview of Programming Languages Before we go into comparing programming languages, let’s first take a look at the languages we’re going to be covering. Dynamic Languages Dynamic languages are generally thought of as easier for total beginners to learn because they’re flexible and fun. You can quickly build an app from scratch with less lines of code, and there is no hard rule on how to write things to behave in the way you want them to. As dynamic languages are usually very high level languages, you’d spend less time trying to get the details right and more time learning programming concepts, which is another reason dynamically typed languages are popular with beginners who are motivated by being able to build things and see results quickly. JavaScript Not to be confused with Java, JavaScript is a primarily client-side scripting language used for front-end development. JavaScript is compatible across all browsers and is used to create interactive

So What is the Kernel? A kernel is the lowest level of easily replaceable software that interfaces with the hardware in your computer. It is responsible for interfacing all of your applications that are running in “user mode” down to the physical hardware, and allowing processes, known as servers, to get information from each other using inter-process communication (IPC). Different Types of Kernels There are, of course, different ways to build a kernel and architectural considerations when building one from scratch. In general, most kernels fall into one of three types: monolithic, microkernel, and hybrid. Linux is a monolithic kernel while OS X (XNU) and Windows 7 use hybrid kernels. Let’s take a quick tour of the three categories so we can go into more detail later.

Pretty much everything else in a computer can be seen as an accessory and can be ha
