A kilobyte is a unit of data or information storage comprised of either 1000 bytes or 1024 bytes. This discrepancy arises from two opposing view points on the matter of the prefix kilo in kilobyte. In electronic memory circuits, a piece of information is found under an addressable location which is a power of 2 (2,4,8,16,32...1024,2048, etc.). So, according to this binary number system a kilobyte equals 2¹⁰ or 1024 bytes. However earlier in technological terminology, 1000 bytes was used as a passable approximation of 2¹⁰, thus the term kilobyte came to be known as 10³ or 1000 bytes. Some hardware manufacturers still use the approximate value for the kilobyte when advertising their hard drives. Additionally there is still a variety of abbreviations used including kB, KB, K, and Kbyte. On Obsessable, KB refers to the kilobyte, while kb refers to kilobits.

All digital information is expressed as a series of 1s and 0s known as bits. Eight bits combine to make a byte, and the more available bytes a storage medium holds, the more information and storage capacity the device has whether it be a hard drive, RAM, memory cache or other method of digital storage.

• 1 Bit = either a 1 or a 0 (which makes up binary code)
• 1 Byte (b) = 8 bits
• 1 Kilobyte (KB) = roughly 1 thousand bytes.
• 1 Megabyte (MB) = roughly 1 million bytes.
• 1 Gigabyte (GB) = roughly 1 billion bytes.
• 1 Terabyte (TB) = roughly 1 trillion bytes.
