Hadoop
-
Python
-
R
-
Apache Groovy
Correct Answer
A. HadoopExplanation
Hadoop is a free, Java-based programming framework that supports the processing of large data sets in a distributed computing environment. It is designed to handle big data processing and storage across a cluster of computers, providing scalability and fault tolerance. Hadoop uses a distributed file system (HDFS) and a processing framework (MapReduce) to efficiently process and analyze large volumes of data. It is widely used in the industry for big data analytics and is known for its ability to handle massive amounts of data in parallel.Rate this question:

-
Deep Analytics
-
Data Visualisation
-
In-memory Analytics
-
Data Analytics
Correct Answer
A. In-memory AnalyticsExplanation
In-memory analytics refers to the approach of querying data that is stored in a computer's random access memory (RAM) instead of physical disks. This approach allows for faster and more efficient data retrieval and analysis as accessing data from RAM is much quicker than accessing it from disks. By keeping the data in memory, in-memory analytics enables real-time analysis and faster decision-making, making it suitable for applications that require quick and interactive data processing.Rate this question:
