Which command loads data from a file into memory?

• A. Openfile command
• B. Readfile command
• C. Load data from file
• D. Read data

Answer: (B)

When you bring data from a file into memory, you need to perform the operation that actually transfers the contents, after you have access to the file. The readfile command does this: it reads the data from the open file and loads it into memory. Opening a file just gives you access and a handle; it doesn’t move the data itself. The option that says to load data from a file is just a description, not a specific command name, and read data could refer to reading from something other than a file or be too generic. So the readfile command is the one that loads the file’s contents into memory.
