What is the Full Form of GB?

The full form of GB is Gigabyte.

Understanding Gigabytes

A gigabyte (GB) is a unit of digital storage capacity. It represents a large amount of data. While often described as one billion bytes (1,000,000,000 bytes), in binary notation (base 2), used in computing, a gigabyte is precisely 2³⁰ bytes, which equals 1,073,741,824 bytes. This difference arises from the way computers handle data using powers of two. The term "giga" comes from the Greek word meaning "giant," reflecting the substantial size of this unit compared to smaller units like kilobytes and megabytes.

• Example: A hard drive might advertise 500 GB of storage, but the actual usable space might be slightly less due to formatting and other factors.

The gigabyte is commonly used to describe:

• The storage capacity of hard drives (HDDs) and solid-state drives (SSDs).
• The size of files, such as videos, images, and software applications.
• The amount of RAM (Random Access Memory) in a computer system.

Several sources confirm this definition:

• javatpoint states that GB stands for Gigabyte, a digital storage unit.
• Leverage Edu also confirms that GB's full form is Gigabyte and highlights its importance in storage technology.
• TechTarget clarifies the binary definition of a gigabyte (2³⁰ bytes).
• Multiple Quora answers (https://www.quora.com/What-is-the-full-form-of-KB-MB-GB-and-TB, https://www.quora.com/What-is-gb) reinforce the Gigabyte definition.
• Testbook provides Gigabyte as the correct answer.

While some sources mention other meanings of "GB" (like gallbladder), in the context of computing and data storage, Gigabyte is the overwhelmingly prevalent and correct interpretation.
