• The different types and sources of data being analyzed
• The sheer amount of data being collected and processed

What type of data does 'variety' encompass in data processing?

• Only structured data
• Only unstructured data
• Only semi-structured data
• Different types and sources of data

In data processing, what does 'velocity' specifically refer to?

• The sheer amount of data being collected and processed
• The efficiency of data processing pipelines and algorithms
• The different types and sources of data being analyzed
• The speed at which data is being generated and processed
