MCQs on Hashing Techniques

1.

In linear hashing, the formula of file load factor is

l = r⁄ (bfr * N)
l = r⁄ (bfr + N)
l = r⁄ (bfr - N)
l = r⁄ (bfr * 2N)

2.

The hashing technique which allocates fixed number of buckets is classified as

dynamic hashing
static hashing
external hashing
internal hashing

3.

The hashing technique which allows increase or decrease in number of buckets without a need of directory is classified as

global depth hashing
linear hashing
relative hashing
local depth hashing

4.

In linear hashing, the formula used to calculate number of records if the blocking factor, loading factor and file buckets are known is as

r =l + bfr + N
r =l - bfr - N
r =l + bfr - N
r =l * bfr * N

5.

If the global depth is more than local depth then the operation must be performed in directory array is

adding
subtracting
halving
doubling
