Learning about computer science !
So, we have seen how we can represent Binary positive and negative integers. Sadly, this does not help . You might have thought about an easy solution, just add a point somewhere. This is indeed correct and helps with this. So, how do you do it with binary numbers? Easy, the numbers to the right…
Binary coded decimal is a way of representing binary numbers into a decimal system. So we have a number that looks like follows: 0000 0000 0000 0000 (16 bits or 2 bytes) where each set of 4 bits represents a decimal place. So the first 4 bits represent the thousands, the next 4 bits the…
Well so far we have just seen positive integers mainly. Now let us speak about negative integers as well. When speaking about this, we can figure out a simple solution. Like in Math’s, instead of adding a + or – at the beginning of the number we add a zero or a one. But there…
Now 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…
In 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…
When 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…
