A Review of Algorithms and Techniques for Analyzing Big Data

Big data is generated from a variety of sources. Data sets can grow rapidly: for instance, social media such as Facebook, Instagram, and Twitter generate terabytes of data every day. Desktop computers and laptops generate tremendous amounts of data. Geospatial data are generated by cell phones and even from satellites. IoT (Internet of Things) devices like sensors and pocket computers are also generating a massive amount of data. "Big data" generates tremendous attention worldwide. This paper aims to provide a more comprehensive description of big data that captures its other specific and distinguishing characteristics, which metrics describe the size and other characteristics of big data, and which tools and technologies exist to leverage the potential of big data.
