A Gigabit (Gb) is a unit of digital information equal to one billion bits (109 bits).
It's a key measurement used to describe the speed of data transfer, most commonly your internet connection speed.
It's easy to mix up a Gigabit (Gb) and a Gigabyte (GB), but they measure two very different things: speed vs. size.
The most important thing to remember is this simple conversion:
This is why a fast 1 Gbps internet connection doesn't download a 1 GB file in one second.
Since a Gigabyte is eight times larger than a Gigabit, it will take about eight seconds to complete the download.
What does a fast internet connection of 1 Gigabit per second (Gbps) mean for your daily use?
It provides the bandwidth needed to power a fully connected home or business, allowing you to:
A gigabit connection is the gold standard for reliable, high-speed internet for modern work, entertainment, and communication.
The prefix "Giga-" comes from the Greek word for "giant," and it represents a massive amount of data.
A single Gigabit is made up of one billion individual bits (the most minor units of digital data, represented by a 1 or a 0).
To put that in perspective, one Gigabit of information is enough to store the text of roughly 1,000 novels.
When you hear about Gigabit speeds, you're talking about the power to move that entire library of information every single second.
A megabit (Mb) is a unit of digital information, equal to one million bits (106 bits). The plural form is megabits.
While it's a fundamental unit of data, it's most commonly used to describe the speed of an internet connection.
When you shop for a broadband plan, the internet speed advertised by providers is measured in megabits per second (Mbps).
This metric defines your data transfer rate—essentially, how many million bits of data your connection can download or upload every second.
For example, a 25 Mbps download speed is great for basic browsing and streaming HD video on one device.
However, a faster plan of 100+ Mbps is better for a household with multiple people streaming 4K video, online gaming, and downloading large files at the same time.
A common point of confusion is the difference between a megabit (Mb) and a megabyte (MB).
The key is to notice the difference between the lowercase 'b' (bit) and the uppercase 'B' (byte).
Think of it this way: a bit is like a single letter, while a byte is like a complete word. Since it takes eight bits to make one byte, a megabyte (MB) is eight times larger than a megabit (Mb).
This is why they're used for different things:
In the world of networking, the "mega" prefix in megabit is simple: it means exactly 1,000,000 bits (106 bits). This is based on the decimal system.
However, you might see "mega" used differently for computer memory or file storage, where it can sometimes mean the binary equivalent of 1,048,576 bits (220 bits).
To avoid confusion, the term mebibit (Mib) was created for the binary value. Still, for measuring your internet speed, megabit (Mb) is the universal standard.
