So let’s go ahead.

Growth of Data and the Need for Data Science

Data science is a field that blends the multiple disciplines of machine learning, algorithms, data inference, programming, mathematics, and statistics to extract useful inferences from raw data and solve complex problems.

A research by Sciencedaily.com, from the year 2019 revealed that 90% of the total data present in the world was created in the 2 years before that. Imagine that. In a matter of two years, we accumulated 9 times the total data collected over thousands of years of humankind combined.

An estimate showed that the amount of data by the end of 2023  was have been a whopping 45 zettabytes. To make all of this information of value and use to us, and to apply it to the real world and practical scenarios, we need data science.

Using Data Science, information and knowledge are extracted from data, to make decisions and predictions, using machine learning, prescriptive analytics, and predictive causal analysis.

It is the field that helps businesses, not just in recognizing their markets and improving their decision-making, but also in getting them closer to their customers. Data Science deals with structured as well as unstructured data. It involves studying historical data.

As data-driven decision-making is becoming more and more popular with time, each company, be it big or small, seeks professionals who can analyze and understand raw data, and help the company utilize it efficiently.

Exploring the Basics of Computer Science

Computer Science, in simple terms, can be defined as the study of computers and computing concepts. It includes computer design, computer architecture, and their applications in technology and science.

Computer science deals with both software, hardware, and other components like the internet and networking, with a large number of research areas to study further in.

The hardware part deals with the study of computer design and its working processes whereas the software part deals with programming concepts and languages. Computer science also comprises Compilers and Operating Systems.

It is the science that enables you to program a computer to do whatever you want. This discipline focuses on problem-solving, and innovation across industries, and teaches how to utilize computers to create, not just to consume.
