A kilobyte is 10 ^ 3 or 1,000 bytes.
A kilobyte (abbreviated as “K” or “KB”) is the smallest unit of measurement that is larger than a byte. But it is less than a megabyte which contains 1,000,000 bytes. At the same time, a kilobyte is technically 1,000 bytes.
Kilobytes are often referred to by many as kibibytes, which contain 1,024 bytes.
Kilobytes are often used to measure the size of small files. For example, a plain text document contains 10 KB of data and therefore has a file size of about 10 kilobytes.
Small website graphics are often between 5 KB to 100 KB. While some files contain less than 4 KB of data, modern file systems such as NTFS (Windows) and HFS + (Mac) have a cluster size of about 4 KB. Therefore individual files typically take a minimum of four kilobytes of disk space.
