Final answer:
Gabriella's question about storage space pertains to Computers and Technology, specifically to the units of computer storage and data management.
Step-by-step explanation:
When Gabriella asked her coworkers about their storage space, she was inquiring into a topic that falls within the realm of Computers and Technology. In a high school setting, students begin to learn about computer storage units and how to manage digital data. Storage space is an essential concept, especially in our modern 'Big Data' era where large datasets such as the Sloan Survey's 15 terabytes of astronomical data must be managed effectively. It is important to understand that computer storage space is measured in bytes, with common units increasing from kilobytes (KB) to megabytes (MB), gigabytes (GB), and terabytes (TB). Each level is a progression of 1024 units of the lesser, starting with 1024 bytes being equivalent to one KB. These measures give us an understanding of the immense volume of data that can be stored and processed by computers today, highlighting how crucial efficient data management has become.
