kilobit
Definition
Noun: A unit of digital information or data storage equal to one thousand (1000) bits. It is commonly used in computing and telecommunications to measure data transfer rates or data quantities.
Usage
The term "kilobit" is used to quantify data size or transmission speed. It is important to distinguish it from the kilobyte (which is 8 times larger, as a byte is 8 bits). It is often abbreviated as kb or kbit.
Examples
- The internet connection has a speed of 100 kilobits per second.
- The image file is approximately 250 kilobits in size.
- Early modems transmitted data at a rate of a few kilobits per second.
Advanced Usage
- In some historical or specific technical contexts based on binary systems, a "kilobit" can sometimes represent 1024 (2¹⁰) bits. However, in modern standard usage (SI units) and in data communications, it is consistently defined as 1000 bits. The term "kibibit" (Kibit) was introduced to explicitly mean 1024 bits.
Variants and Related Words
- Kilobyte (KB): A unit of information equal to 1000 bytes (or 8000 bits).
- Megabit (Mb): A unit equal to one million bits or one thousand kilobits.
- Kibibit (Kibit): A unit of information equal to 1024 bits.
Synonyms
- kb (common abbreviation)
- kbit (standard abbreviation)
Related Phrases
- kilobits per second (kbps): A unit of data transfer rate, indicating thousands of bits transmitted each second.
- Example: The audio stream uses a bitrate of 128 kbps.
Noun
-
