Final answer:
The three features of big data that have significantly altered organizational technology requirements are Volume, Velocity, and Variety. The vast amounts of data need advanced algorithms and massive computing power to be processed, and different data types require specialized handling.
Step-by-step explanation:
The three features of big data that have changed technology requirements for organizations are Volume, Velocity, and Variety. The staggering amount of data produced, such as those from the Sloan Survey that reached 15 terabytes, has necessitated the advancements in technology to handle this. The Volume refers to the sheer size of data that organizations collect which can range from terabytes to petabytes of information. Velocity indicates the speed at which new data is generated and the pace at which it needs to be processed.
Variety describes the different types of data available, which can be structured, unstructured, or semi-structured, each requiring different processing techniques. To efficiently sort through this big data, supercomputers and advanced computer algorithms have become essential. Furthermore, approaches such as 'citizen science' have been implemented to manage the data, such as the Galaxy Zoo project, which assisted in classifying millions of galaxies with the help of over 100,000 volunteers.
