Modern computers today use a binary number representation system called 'Two's complement'. It is a fixed number of binary digits used in computer calculations. Basic math operations such as addition and subtraction can be performed using the binary rules of addition and subtraction. Two's complement is not a complex scheme and is rather very simple to work with. This system also helps overcome the shortcomings of having to deal with magnitudes. Two's complement can be characterized as:

In the last article, which you can read here, I was talking about which PC components are crucial for programmers. Basically, I listed all the components to worry about, but I’ve also said that you need to keep the Bottleneck in mind. Because, there’re a lot of people who don’t know what is a bottleneck, in this article, I’ll try to explain what that is.
If you have ever wondered if there is any Desktop PC that comes at a very cheap price, you probably wouldn't have looked at Raspberry Pi, no one did.

Gordon Moore, the founder of Fairchild Semiconductor and former CEO of Intel in his 1965 paper, described that the number of transistors in a dense integrated circuit double about every two years and this statement is famously known as Moore's Law. Moore's law was consistent for the past 50 years, but with the current technological advancements, it is coming to an end. It is starting to become physically impossible to reduce transistor sizes to increase computational efficiency further, and hence this calls for alternate methods.
