Abstraction

Posted by Brass Orchid, on Aug 29th, 2005

Right. It's all about abstraction. The actual interface is unknown to the programmer, and you don't care. The language interpreter takes care of all of that for you. You don't have to know the hardware at all. There is an abstract layer between you and the target device, in which all the generalized instructions are converted to device specific code calls. That was the dream of the C language, based upon the virtual machine, using stdin, stdout, stderr, and all that. The programmer is removed from machine level specifics and free to just deal with features and leave basic functionality to the compiler and interpreter for the specific target devices, dealing with the software, rather than the hardware.

We will shun all technology, remove all memory of our flawed elders, and create a new world and man in our own perfect image!
