With a dedicated learning plan, anyone can master these components within six months and quickly secure data science roles.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-faqs\"><span class=\"ez-toc-section\" id=\"FAQs\"><\/span><strong>FAQs<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-what-are-the-main-components-of-data-science\"><span class=\"ez-toc-section\" id=\"What_are_the_main_components_of_data_science\"><\/span><strong>What are the main <strong>components of data science<\/strong>?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Basically, there are 5 primary components of data science:<\/p>\n\n\n\n<ul>\n<li>Data<\/li>\n<\/ul>\n\n\n\n<ul>\n<li>Programming Language<\/li>\n<\/ul>\n\n\n\n<ul>\n<li>Statistics<\/li>\n<\/ul>\n\n\n\n<ul>\n<li>Machine Learning<\/li>\n<\/ul>\n\n\n\n<ul>\n<li>Big Data<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-what-is-the-purpose-of-machine-learning-in-data-science\"><span class=\"ez-toc-section\" id=\"What_is_the_purpose_of_Machine_Learning_in_data_science\"><\/span><strong>What is the purpose of Machine Learning in data science?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Notably, machine learning stands as a key part of data science. Specifically, it builds models that predict or classify. These models help us sort data and uncover hidden patterns.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-how-is-data-science-different-from-data-engineering\"><span class=\"ez-toc-section\" id=\"How_is_data_science_different_from_data_engineering\"><\/span><strong><strong>How is data science different from data engineering?<\/strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>While both are interconnected, data engineering and data science serve different purposes:<\/p>\n\n\n\n<p>Mainly, data engineering gathers, keeps, and handles huge amounts of data well. Thus, it makes sure the data is organized and easy to use.<\/p>\n\n\n\n<p>Essentially, data science looks at, builds models from, and finds insights in data.
