1. Sequential access is the main access mode only in batch systems, whereas files are used and updated at regular intervals.
2. Direct access - on-line processing requires direct access, whereby a record can be accessed without accessing the records between it and beginning of the file.

Answer:
log base 3a= -0.631.log a/3 base 3
Now, -log m= log 1/m
hence,
log base 3a= 0.631.log 3/a base 3
log base 3a/log 3/a base 3 =0.631
log base 3 ( a.3/a) =.631 since, log m/logn =log n(m)
log base 3 3=0.631
Hence, answer is log base 3 3=0.631
