The first getc reads a large block (8K bytes typically) from disk
into RAM. Subsequent getc's just increment a pointer,
check for the end of the block, and fetch the next byte
from RAM. When the block is used up, the O/S is called and
the next 8K block is read in. getc does not call the O/S for
each byte, just every 8192 bytes (more or less,
depending on the particular O/S).
