GB is equal to

Category: Miscellaneous Indian Gk

Correct Answer: B) 1024 MB.

Exam Relevance: UPSC, GATE, GRE, GMAT, Computer Science Exams

Difficulty: Easy

Concept notes:

In computing, data storage units are based on powers of 2. A gigabyte (GB) is a unit of digital information that is equal to 1024 megabytes (MB). This is because the binary system, which is fundamental to computing, uses powers of 2. Understanding these units is crucial for managing computer storage and memory.

Common Mistakes:
  • Confusing binary units with decimal units (1000 vs 1024).
  • Assuming GB is 1000 MB, which is a common misconception due to the decimal system.
  • Not understanding the binary system's role in computing.
Explanation:

In the context of computing and data storage, understanding the units of measurement is crucial. The units are based on the binary system, which is a fundamental aspect of computing. The binary system uses powers of 2, unlike the decimal system which uses powers of 10.

The basic units of data storage in computing are as follows:

- 1 byte (B) = 8 bits

- 1 kilobyte (KB) = 1024 bytes

- 1 megabyte (MB) = 1024 kilobytes

- 1 gigabyte (GB) = 1024 megabytes

- 1 terabyte (TB) = 1024 gigabytes

The question specifically asks about the conversion between gigabytes (GB) and megabytes (MB). According to the binary system, 1 GB is equal to 1024 MB. This is because 1 GB is 2^10 MB, and 2^10 equals 1024.

It is important to note that while the decimal system might suggest that 1 GB is 1000 MB, this is not the case in computing. The binary system is used because it aligns with the way computers process and store data. Each unit in the binary system is a power of 2, which simplifies the internal operations of computers.

Understanding these units and their conversions is essential for managing computer storage, memory, and data. It is also important for various competitive examinations and computer science courses where knowledge of data storage units is tested.

In summary, the correct answer is that 1 GB is equal to 1024 MB, reflecting the binary system used in computing. This conversion is a standard and widely accepted fact in the field of computer science and data storage.

Option Analysis:
  • Option A: This option is incorrect. It suggests that 1 GB is equal to 100 MB, which is not accurate. The correct conversion is 1 GB = 1024 MB. This misconception might arise from a misunderstanding of the binary system used in computing, where units are based on powers of 2 rather than 10.
  • Option B: This option is correct. 1 GB is indeed equal to 1024 MB. This is because the binary system, which is fundamental to computing, uses powers of 2. Therefore, 1 GB (gigabyte) is 2^10 MB (megabytes), which equals 1024 MB. This is a standard conversion in computing and data storage.
  • Option C: This option is incorrect. It suggests that 1 GB is equal to 500 MB, which is not accurate. The correct conversion is 1 GB = 1024 MB. This misconception might arise from a misunderstanding of the binary system used in computing, where units are based on powers of 2 rather than 10.
  • Option D: This option is incorrect. It suggests that 1 GB is equal to 200 MB, which is not accurate. The correct conversion is 1 GB = 1024 MB. This misconception might arise from a misunderstanding of the binary system used in computing, where units are based on powers of 2 rather than 10.
