KB has the prefix Kilo. Megabyte is times bigger than Kilobyte. Megabyte MB is a unit of transferred or stored digital information, which is extensively used in information and computer technology. In SI, one megabyte is equal to 1,, bytes. At the same time, practically 1 megabyte is used as 2 20 B, which means 1,, bytes.
Nowadays, the amount of information measured by megabytes is used for representing the size of a typical MP3 file, the size of a JPEG image, and so on. Kilobyte KB is a common measurement unit of digital information including text, sound, graphic, video, and other sorts of information that equals to bytes.
The symbol for a kilobyte is KB. According to the standards of SI, the prefix of mega is used for expressing of multiplication of a unit.
Similarly, a megabyte is considered a unit of data volume which is equal to 1 bytes. A megabyte is one of the most commonly used unit in telecommunication, networking, computer technology, etc. The symbol for this unit is MB. Rather than using the prefix "mega," within this system of prefixes, 2 is referred to as a mebibyte.
Current use: Megabytes are widely used in data storage for file sizes documents, photos, videos, etc. Today however, storage devices are typically larger, often involving either gigabytes 3 bytes or terabytes 4 of data. A page of ordinary Roman alphabetic text takes about 2 kilobytes to store about one byte per letter. A typical short email would also take up just 1 or 2 kilobytes.
Text is one of the most naturally compact types of data at about one byte required to store each letter. In non-roman alphabets, such as Mandarin, the storage takes up 2 or 4 bytes per "letter" which is still pretty compact compared to audio and images. An MP3 audio file of a few minutes or a 10 million pixel image from a digital camera would typically take up few megabytes. The rule of thumb for MP3 audio is that 1 minute of audio takes up about 1 megabyte.
Audio and image and video data typically stored in "compressed" form, MP3 being an example. We'll talk about how compression works later. A data CD disk stores about MB.
