for running multiple programs on a smartphone
for controlling airplane systems that require immediate responses

for managing tasks on a home computer

Explanation:

In Excel, the cell naming convention uses column letters first and row numbers second. So, cell A1 means column A (first column) and row 1 (first row). Data labels in Excel charts show the exact values on top of bars. Real - Time Operating Systems (RTOS) are designed for systems that require immediate responses, like airplane systems where delays can be catastrophic. Running multiple programs on a smartphone, processing large - batch jobs, or managing home computer tasks do not typically require the strict real - time response capabilities of an RTOS.

Answer:

1. D. First column, first row
2. B. Data Labels
3. B. For controlling airplane systems that require immediate responses
