A bit (short for binary digit) is the most basic unit of data in computing.
It is the smallest possible piece of information a computer can handle. Think of a bit as a tiny light switch that can only be in one of two states: on (represented by a 1) or off (represented by a 0).
Every action you perform on a computer—from typing a letter to watching a video—is made possible by billions of these switches working together.
This simple on/off system, known as the binary system, is the fundamental language of all modern digital devices.
The word "bit" is a portmanteau, a blend of the words "binary digit."
It was coined by the brilliant mathematician and engineer Claude Shannon in his groundbreaking 1948 paper, "A Mathematical Theory of Communication."
Shannon, often called the "father of information theory," created this simple term to describe the most fundamental unit of digital information.
While a single bit doesn't hold much information on its own, computers group them together to represent more complex data.
Data is most commonly measured in bytes.
A byte is a sequence of 8 bits. This grouping allows for 256 (28) different combinations of 0s and 1s, which is enough to represent all the characters on your keyboard, including letters, numbers, and symbols.
From the byte, we get larger units of data storage:
You've likely seen internet speeds advertised in megabits per second (Mbps). This measures how many millions of bits can be transferred per second.
However, file sizes are measured in megabytes (MB). To understand your actual download speed, you need to convert bits to bytes.
Since there are 8 bits in a byte, you simply divide the Mbps value by 8.
Example: A 100 Mbps internet connection can download 12.5 megabytes (MB) of data per second (100 Mbps / 8 = 12.5 MBps).
A kilobit (kb) is a unit of digital information equal to 1,000 bits.
It's one of the basic building blocks for measuring digital data.
A common point of confusion is the difference between a kilobit (kb) and a kilobyte (KB).
The key is the capitalization of the letter 'b'. Since one byte is made up of eight bits, a kilobyte is eight times larger than a kilobit.
Think of it like this:
Here's a simple breakdown:
Historically, computing has used different counting systems, which has led to two definitions for a kilobit.
In telecommunications and data transfer, a kilobit strictly follows the decimal system, meaning 1 kilobit (kb) = 1,000 bits. This is the most common definition used today.
However, in some computing contexts like measuring memory, a binary system was used, where 1 kilobit could equal 1,024 bits (210 bits).
To resolve this ambiguity, the term kibibit (Kib) was introduced to specifically denote 1,024 bits. However, 'kilobit' is still widely used in general terms.
The most common real-world application for kilobits is measuring data transfer rates, like your internet connection speed.
Speeds are often expressed in kilobits per second (kbps) or the more common megabits per second (Mbps), where 1 Mbps equals 1,000 kbps.
For example, an older dial-up connection might have a speed of 56 kbps, while a basic broadband plan might be 25 Mbps (or 25,000 kbps).
This measurement tells you how much data can be transferred every second.
