Understanding The Basics of Code

What is code and how does it work?

-????????? Code: It is a set of rules and instruction written in a programming language which help us to talk to machine.

-????????? Coders: People who Codes, i.e., they write small sequences of tasks that they want machine to perform.

Internet vs World Wide Web.

[Worldwide Web is an application built using Internet]

-????????? Internet: Global network of computer connections that allows to transfer information between each other.

-????????? Web: Collection of billions of pages of information that are made using code.

• For example, Coding languages for web are:

§? Html (What to display)

§? CSS (How to display)

§? JavaScript (What is its function)

§? Etc

Introduction to programming languages:

-????????? There are over 250 languages of programming. Why do we need so many languages to communicate with machine?

o?? It’s much quick to communicate to computer through language built for a specific task, rather than using a generic one for everything.

o?? Most basic language that computer understands is binary. That is 0 and 1.

We can categorise different programming languages based on level of abstraction. The lower the level of abstraction- the closer the language is closer to 1’s or 0’s of Binary (How difficult for human to master).The higher the level, further away from Binary- Easy for human to use.

How code powered daily life?

-????????? Every device that we use based on technology works on certain set of instructions (basically code), from phone, cars, smart bands, etc, to rockets and satellites.

API’s (Application programming interfaces)

-????????? Set of definitions and protocols for building and integrating application software.

-????????? API’s let your products or services to communicate with other products or services without having to know how they are implemented.

Artificial intelligence and machine learning.

-????????? Artificial intelligence and machine learning are both the branches of computer science that contribute to make machines take more smarter decision.

-????????? Artificial intelligence is already impacting our life in a better way. Machine learning is a technique used to further develop artificial intelligence programs. Machine learning programs identify patterns, predictions and learn from examples without being a program to explicitly do so.

-????????? AI takes it from ML, what have learned from its environment to make better and smart decision.
