What is the bit count for one Terabit (Tb)?

One Terabit (Tb) is equal to 1 trillion bits. The terminology used in data measurement adheres to a base-10 system where each increment represents a power of ten. A Terabit specifically is defined as 1,000 gigabits (Gb), where each gigabit is 1,000 megabits (Mb), and so forth down the line through kilobits and bits.

To break it down:

• 1 Terabit = 1,000 Gigabits

• 1 Gigabit = 1,000 Megabits

• 1 Megabit = 1,000 Kilobits

• 1 Kilobit = 1,000 bits

Therefore, to convert from Terabits to bits:

1 Tb = 1,000 x 1,000 x 1,000 x 1,000 b = 1,000,000,000,000 b.

This calculation confirms that the bit count for one Terabit is indeed 1 trillion bits, which is accurately represented by the correct answer.
