### After the one, how many zeros does a byte have if you're describing a gigabyte with it?

• A.

15

• B.

6

• C.

12

• D.

9

D. 9
Explanation
A byte consists of 8 bits. To describe a gigabyte, we need to convert it to bits. 1 gigabyte is equal to 8 billion bits. Since a byte has 8 bits, we divide 8 billion by 8 to get the number of bytes in a gigabyte, which is 1 billion. The question asks for the number of zeros in a byte when describing a gigabyte, so the answer is 9.

### At 2.2 Mbit/s and totalling 1 gigabyte—what's the duration of the SDTV video?

• A.

One hour and a half hours

• B.

One hour

• C.

Two hours

• D.

Three and a half hours

B. One hour
Explanation
The given information states that the video has a total size of 1 gigabyte and is being transmitted at a rate of 2.2 Mbit/s. To determine the duration, we can convert the total size of the video from gigabytes to bits. Since 1 gigabyte is equal to 8 gigabits, the video has a total size of 8 gigabits. Dividing this by the transmission rate of 2.2 Mbit/s, we get approximately 3.64 seconds. Therefore, the duration of the SDTV video is approximately one hour.

It is a binary multiple of a byte, meaning it is based on powers of 2. 1 GiB is equal to 1.024 GB, where "GB" stands for "gigabyte" which is a decimal multiple of a byte based on powers of 10.
