What is a blog? 

A “blog” is an online journal or informational website displaying information in the reverse chronological order, with latest posts appearing first. It is a group where a person or group of people write and share their views on an individual subject. The appearance of blogs changed over time, and nowadays blogs include different items.

What is a Voronoi Diagram?

A “Voronio Diagram” is basically partitioning of a plane with points into convex polygons such that each polygon contains exactly one initial point and every point in a given polygon is closer to its generating point than to any other.

What is Crowd-sourcing?

It’s the practice of obtaining information or input into a task or project by enlisting the services of a large number of people either paid or unpaid, typically via the Internet. These services include ideas and finances from a large relatively open group of internet users, it divides work between participants to achieve a cumulative result.

Binary Addition and Subtraction

Binary addition is much like normal everyday addition (decimal addition), except that it carries on a value of 2 instead of a value of 10.

For example: in decimal addition, if you add 8 + 2 you get ten, which you write as 10; in the sum this gives a 0 and a carry of 1. Something similar happens in binary addition when you add 1 and 1 the result is two, but since two is written as 10 in binary, we get after summing 1 + 1 in binary, a digit 0 and a carry of 1.

0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 10 (which is 0 carry 1)

Binary subtraction is similar to binary addition, there is little difference between binary and decimal subtraction except those that arise from using only the digits 0 and 1. In binary subtraction, the only case where borrowing is necessary is when 1 is subtracted from 0. When this occurs, the 0 in the borrowing column essentially becomes “2” while reducing the 1 in the column being borrowed from by 1. If the following column is also 0, borrowing will have to occur from each subsequent column until a column with a value of 1 can be reduced to 0.

Hexadecimal Colors

Hexadecimal numbers are used on web pages to set colors. A color can be made by mixing RedGreen and Blue, so it is called the “RGB Color System”. It is also called an “Additive” color system, because it starts at black, and then color is added. Each byte, or pair of characters in the Hex code, representing the intensity of red, green and blue in the color respectively. Hex code byte values range from 00, which is the lowest intensity of a color, to FF which represents the highest intensity.

Logic Gates

A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output. At any given moment, every terminal is in one of the two binary conditions low or high, represented by different voltage levels. It performs a logical operation on one or more binary inputs and produces a single binary output.

How does the Half Adder works?

A half adder is a type of adder, an electronic circuit that performs the addition of numbers. The half adder is able to add two single binary digits called as augend and addend and produces two outputs as sum and carry. The adder works by combining the operations of basic logic gates, with the simplest form using only a XOR and an AND gate. This can also be converted into a circuit that only has AND, OR and NOT gates.

How does the Full Adder works?

The full-adder circuit adds three one-bit binary numbers (C A B) and outputs two one-bit binary numbers, a sum (S) and a carry (C1).   The full-adder is usually a component in a cascade of adders, which add 8, 16, 32, etc. binary numbers.  The carry input for the full-adder circuit is from the carry output from the circuit “above” itself in the cascade.  The carry output from the full adder is fed to another full adder “below” itself in the cascade.
