DetailsNow that you know how to convert numbers in binary, you should also know a bit how to add numbers. We are focusing mainly on binary, because it is the most important for computer science. This method works mainly as with decimal systems. Let us see the basics: 0+0=0 0+1=1 1+0=1 1+1= 0 carry one…
DetailsIn Technical Informatics, number systems are important. I mean, just like in any other field. You must know how to represent your numbers. A Number Representation is when you take a set of numbers and make it into a set and do operations with it. Sounds awfully like groups in abstract algebra (we talked about…
DetailsWhen you think about computer science, what is the first thing that comes to your mind? Complex Algorithms? How computers are built? CPU Processors? Which field are we talking about? Well, to get started we are not talking about an engineering or software development in itself. Computer Science is a field of study that focuses…
DetailsAn IP is an Internet Protocol. So basically it is an Internet Protocol version six. The most recent one. This protocol was designed and developed in 1995 and it started being implemented by the 2000’s by all mayor computer brands and servers. Right now, your computer is most likely compatible with IPv6.
