Answer:

2 times as many items can be uniquely identified

Explanation:

Option 'C' is the answer. because

if we use 6 bit binary sequence

then

No. of Unique address will be = 2 ^ 6  = 64

as we increase the bit by 1. Now total bits are 7.

so

No. of Unique address for 7 bit Sequence = 2 ^ 7  = 128

So,

128 is double of 64, that is 2 times greater value than 64.

Sonic the Hedgehog (1991)
e-lub [12.9K]

Answer:

What if we made a fast game?

Explanation:

The mascot is the person, animal or thing which brings good luck, just like Mario. However, this is not a problem with Sonic the Hedgehog. And the Hedgehog is powerful enough to cross any barrier. Hence tieing the collectibles is not required. And the Hedgehog is quite cute and domestic. But it moves only 10 meters per second if we are considering the maximum speed. Hence, the correct option is certainly what if we made a fast game? And this is option C.
