For digital information, the kilobyte is used as multiple of “byte”. The International System of Units has defined the prefix “kilo” as 1000 and therefore one kilobyte is used to denote 1000 bytes. The symbol for this unit is KB. In computer dictionary the kilobyte has been abbreviated as K and KB. In order to make a difference between the decimal K which stands for 1000 and binary K which stands for 1024, the IEEE recommended using small “k” for decimal kilo and capital “K” for binary kilo.

The binary connotations of megabyte and kilobyte are used by Linux and Windows operating systems at times of reporting file sizes and disk capacities. Internet usage refers to the quantity of data in kilobytes, bytes, gigabytes, or megabytes that are transferred between a computer and Internet. Data may be either transferred from the Internet to the desktop through downloads or from the computer to the Internet through uploads. A single kilobyte refers to a collection of 1000 bytes; so a single page of regular Roman alphabet txt will typically take up about 2 kilobytes of storage. A short email is also likely to take up one or two kilobytes. Text is a compact data type and it usually takes one byte to store every alphabet. In the non Roman alphabet type, storage is higher, about 2-4 bytes for every letter.
