A terabyte (TB) is a unit of digital information equal to one trillion bytes (1012 bytes).
To put that massive number into perspective, if one byte was a single printed letter, a terabyte could hold the text of over one million books.
Understanding these units is key to knowing how much data your devices can store.
A single terabyte (TB) can store an enormous amount of digital information.
For most people, 1 TB offers more than enough space for years of use. Here's what a terabyte looks like in practical terms:
This vast capacity is why external hard drives and cloud storage plans are now commonly measured in terabytes, meeting the demands of modern high-resolution media and large files.
While the terms are often used interchangeably, a terabyte and a tebibyte represent different amounts of data.
This discrepancy is why your new 1 TB hard drive shows up as approximately 931 GB in your computer.
The OS is measuring in tebibytes but often mislabels it as terabytes or gigabytes.
The first terabyte hard drive was introduced in 2007, a milestone that once seemed impossibly large.
Today, terabyte-sized drives are standard for consumer laptops, desktop computers, and gaming consoles.
As data creation continues to explode, the world is moving beyond the terabyte. The next major unit of measurement is the petabyte (PB), which is equal to 1,000 terabytes.
Large-scale data centers for companies like Google and Meta now manage data measured in exabytes—equivalent to one million terabytes.
Ever wondered what a gigabyte (GB) really means when you're buying a new phone, choosing a mobile data plan, or saving a file? A gigabyte is one of the most common measurements of digital capacity.
In this guide, we'll break down exactly what a GB is, what you can fit into it, and why the storage space you buy isn't always what you see on your device.
A gigabyte (GB) is a unit of digital data storage, equal to one billion bytes. The plural form is gigabytes.
While a gigabyte (GB) is commercially defined as 1 billion bytes (109 bytes), operating systems like Windows often measure storage using a binary system.
In this system, the correct term is a gibibyte (GiB), which is equal to 230 or 1,073,741,824 bytes.
This ~7.4% difference is why a hard drive advertised as 500 GB might appear as only 465 GiB on your computer.
This discrepancy exists because manufacturers sell storage using the decimal system (powers of 10), while most operating systems measure it using the binary system (powers of 2).
A single gigabyte (1GB) offers a substantial amount of storage for everyday use.
For perspective, 1 GB can typically hold:
This capacity makes it a standard unit for measuring file sizes, app downloads, and mobile data plans.
In the early 1980s, a gigabyte of storage was an immense, costly amount of data, primarily found in multi-million dollar supercomputers.
The first gigabyte-capacity hard disk drive, IBM's 3380, was released in 1980. It weighed over 500 pounds and cost tens of thousands of dollars.
Today, gigabytes are a routine measure for devices that fit in our pockets, such as smartphones, SD cards, and USB drives, showcasing the exponential growth of data technology.
