What is Bit (b)?
Answer: A bit (b) is the most fundamental unit of digital information, representing a binary value of either 0 or 1. Every form of digital data—whether text, video, or music—is ultimately stored as combinations of bits. Though a single bit is minimal and cannot carry much information, billions of bits collectively form complex systems of communication and storage. In essence, bits are the DNA of the digital world, forming the foundation upon which all computing is built.
What is Byte (B)?
Answer: A byte (B) is equal to 8 bits, and it is the standard building block of data measurement. A byte can represent 256 unique values (2⁸), which is enough to store a single character such as a letter, number, or symbol. Larger digital files such as text documents, songs, and software applications are all measured in multiples of bytes. Without bytes, digital information would be too granular and impractical to manage.
