I am reading Operating Systems by William Stallings 6th edition and I came across this text,
A number of steps need to be performed to execute a
program. Instructions and data must be loaded into main memory, I/O devices
and files must be initialized, and other resources.
Now I am unable to understand how I/O devices and files are initialized on program execution? I assume it meant to start the I/O resources but what about the files? Please guide. Thanks
