Learn: Bit, Nibble, Byte – What They Mean

Welcome!Building on what you've already learned about memory and storage, let's explore how data is represented in computers using bits, nibbles, and bytes. This lesson will help you understand these terms and why they are important.

What is a Bit?A bit is the smallest unit of data in a computer. It can represent two values: 0 or 1, which are the building blocks of binary (the language of computers). Bits are used to store information like on/off states.

What is a Nibble?A nibble is a group of 4 bits. It allows computers to represent more complex data. For example, in binary, 1010 is one nibble.

What is a Byte?A byte is a group of 8 bits. It is commonly used to represent one character, like a letter or number in ASCII. Bytes are a fundamental unit for measuring data in computers.

Why Bits, Nibbles, and Bytes MatterData in computers is stored and processed using combinations of bits, nibbles, and bytes. For example, a byte can represent a single letter, and groups of bytes make up files and programmes. Understanding these units helps us calculate file sizes and storage needs.

Review Time!Great work! You've learned about bits, nibbles, and bytes. Let's review these concepts with some final questions to reinforce your understanding.
