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

Which one best describes it?
Correct Answer
C. 1024^3
Explanation
The correct answer is 1024^3, which represents 1024 raised to the power of 3. This means that 1024 is multiplied by itself three times. Therefore, the answer is 1,073,741,824.

How many gigabytes can a dual-layered DVD+R disc hold?
Correct Answer
A. 8.5
Explanation
A dual-layered DVD+R disc can hold 8.5 gigabytes of data. This type of disc has two layers of data storage on one side, allowing for a larger storage capacity compared to single-layer discs. The 8.5 gigabytes of storage space is useful for storing large files, such as high-definition videos or large software programs.

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

1 GiB can be translated to
Correct Answer
C. 1 074 GB
Explanation
The correct answer is actually 1.024 GB, not 1 074 GB. The term "GiB" stands for "gibibyte" which is a unit of digital information storage. 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.

A 500 GB hardisk is reported as what in Windows?
Correct Answer
B. 465 GB
Explanation
In Windows, a 500 GB hard disk is reported as 465 GB. This is because of the difference in the way storage capacity is calculated. Manufacturers use the decimal system, where 1 GB is equal to 1 billion bytes. However, Windows uses the binary system, where 1 GB is equal to 1,073,741,824 bytes. As a result, when Windows calculates the storage capacity, it shows a slightly lower value, which in this case is 465 GB.
