Binary&Denary
Binary-Binary is a base 2 number system that is made up of only two numbers 0 and 1. This number system is the basis for all binary code, which is used to write data such as the instructions that computer processors use, or the digital text you read every day.
Denary- also known as "decimal" or "base 10," is the standard number system used around the world. It uses ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) to represent all numbers. Denary is often contrasted with binary, the standard number system used by computers and other electronic devices.
The following chart illustrates the binary number 01101000. Each column represents the number two raised to an exponent, with that exponent's value increasing by one as you move through each of the eight positions. In this example, we get the total value(8+32+64) = 104. As you can see, we do not count the bits with a 0 because they're "turned off."

Value:1286432168421
ON/OFF:01101000

Hexadecimal
Uses of Hexadecimal
What are hexadecimals used for?
Hexadecimal numbers are often used to represent colours within HTML or CSS.
Hexadecimal numbering system is often used by programmers to simplify the binary numbering system.
-To define locations in memory.
-To define colours on web pages.
-To represent Media Access Control (MAC) addresses.
-To display error messages.
Cascading Stylesheets (CSS)CSS is a presentation language used in web development. It has a sole purpose of providing a web browser with styling instructions for HTML code.
MAC address A Media Access Control address (MAC address) is a unique number given to every device that connects to the internet or a network. It identifies the actual device.
Hypertext Markup Language [HTML]
HTML is a language used to create web pages. It is responsible for the content and structure of a page. HTML takes its styling instructions from another language called CSS.

Hexadecimal describes a base-16 number system. It describes a numbering system containing 16 sequential numbers as base units before adding a new position for the next number. The hexadecimal numbers are 0-9 and then use the letters A-F. We show the equivalence of binary, decimal, and hexadecimal numbers in the table below.
Logic gate
Not gate
-The output x is 1 if the input A is 0
AND gate
-The output x is 1 if both inputs A and B are one
Or gate
-The output x is 1 if either input A or B is one
Nand gate
-The output x is 1 if input A and B is not both one
Nor gate
-The output x is 1 if neither input A nor input B is one
Xor gate
-The output x is 1 if input A is one and input B is zero. OR input B is one and input A is zero.
Computational thinking
Computational Thinking (CT) is a problem solving process that includes a number of characteristics and dispositions.
Computational thinking allows us to take a complex problem, understand what the problem is and develop possible solutions. We can then present these solutions in a way that a computer, a human, or both, can understand.
This course provides an opportunity to experience some of the elements of Ccomputational thinking>>
