Which action reads data from a file into memory?

• A. Open file
• B. Write file
• C. Read file
• D. Close file

Answer: (C)

Reading data from a file into memory is done by the read operation. This action pulls the file’s contents so the program can work with them in RAM. Typically you first open the file to obtain access, then read to load the data, and finally close when you’re finished. Opening prepares access but doesn’t transfer the data. Writing sends data from memory out to the file, not into memory. Closing ends the access to the file (and may flush buffers) but doesn’t load the file’s contents into memory.
