Big data refers to the large and complex data sets that are too difficult to process using traditional data processing techniques. Big data is characterized by the 3 Vs: volume, variety, and velocity. Big data is used in many applications, such as marketing analytics, fraud detection, and recommendation systems. Popular big data frameworks include Hadoop, Spark, and Kafka. See the full story Quantum computing is a type of computing that uses quantum mechanics to perform operations on data. Quantum computing has the potential to solve complex problems that are currently infeasible for classical computers, such as cryptography and drug discovery. Quantum computing hardware is still in the experimental phase, but popular quantum computing platforms include IBM Quantum, D-Wave, and Rigetti.
