The dimension of information in the computer is measured in kilobytes, megabytes, gigabytes, and also terabytes. In this section, we"ll watch at common sizes you would watch in actual life and also learn just how to reason around various numbers of bytes.

You are watching: Which is bigger megabyte or kilobyte

## Kilobyte or KB

Kilobyte KB - around 1 thousand bytesAs us know, 1 byte is one typed character - see below for why the expression "about 1 thousand" is forced hereAn email without pictures is about 2 KBA 5 page file might it is in 100 KBText is compact, requiring few bytes contrasted to pictures or sound or videoe.g. 23,000 bytes is around 23 KBOne kilobyte (KB) is a repertoire of about 1000 bytes. A page of plain Roman alphabetic message takes around 2 kilobytes to keep (about one byte per letter). A typical quick email would also take up just 1 or 2 kilobytes. Text is one of the many naturally compact species of data at around one byte required to save each letter. In non-roman alphabets, such together Mandarin, the warehouse takes up 2 or 4 bytes per "letter" i m sorry is still pretty compact compared to audio and also images.

## Megabyte or MB

Megabyte (MB) - around 1 million bytesaka about 1000 KBMP3 audio is about 1 megabyte per minuteA high high quality digital snapshot is about 2-5 megabytese.g. 45,400 KB is 45.4 MBOne megabyte is around 1 million bytes (or around 1000 kilobytes). One MP3 audio document of a couple of minutes or a 10 million pixel image from a digital camera would generally take up few megabytes. The rule of thumb for MP3 audio is that 1 minute of audio take away up about 1 megabyte. Audio and image and video clip data commonly stored in "compressed" form, MP3 being an example. We"ll talk about how compression functions later. A data CD disk stores around 700 MB. The audio top top a CD is no compressed, which is why the takes for this reason much more space than the MP3. The series of bits are represented as spiral path of tiny pits in the silver product in the disk. Imagine that each pit is understood as a 0, and also the lack of a pit is a 1 as the spiral succession is read. Funny fact: the totality spiral ~ above a CD is end 5km long.

## Math - You shot It

2,000,000 bytes is about how countless MB?

## Gigabyte or GB

Gigabyte GB = about a exchange rate bytesaka about 1000 MBGB is a common unit for contemporary hardwaree.g. 4000 MB = 4 GBAn ordinary computer system might have: -4 GB or ram -256 GB the persistent storageA DVD disk has actually a volume 4.7GB (single layer)-Figure 2 GB every hour of video clip (varies greatly)A flash drive might hold 32 GBA hard drive might hold 750 GBOne gigabyte (GB) is around 1 billion bytes, or 1 thousand megabytes. A computer system might have 4 GB that RAM. A flash storage card provided in a camera can store 16 GB. A DVD movie is approximately 4-8 GB.Math - You try ItHow countless GB is 4,000,000,000 bytes?

## Terabyte or TB

One terabyte (TB) is around 1000 gigabytes, or roughly 1 sunshine bytes. You can buy 4 TB difficult drives today, so we are beginning the time once this term comes in to common use. Gigabyte supplied to it is in an exotic term too, till Moore"s law made the common.

## Gigahertz - Speed, no Bytes

One gigahertz is 1 billion cycles per second (a megahertz is a million cycles every second). Gigahertz is a measure of speed, really roughly the rate that in ~ a CPU can do the simplest procedure per second. Gigahertz does not specifically tell you how easily a CPU gets occupational done, yet it is approximately correlated. Greater gigahertz CPUs likewise tend to be more expensive to produce and they use more power (and as a result give off much more heat) - a challenge for putting fast CPUs in little devices choose phones. The ARM firm is famous for developing chips the are an extremely productive through minimal power and heat. Almost all cell phones at this time use eight CPUs.

## Kilobyte / Megabyte / Gigabyte word Problems

You must be comfortable doing simple arithmetic to number MB / GB sizes, simply as you should have the ability to do straightforward computations v second, miles, kilos and so forth.Basic plan: before adding measures X and Y, convert them to be in the very same units.Word ProblemsSolution
Alice has 600 MB the data. Bob has actually 2000 MB that data. Will it all fit ~ above Alice"s 4 GB ignorance drive?show
Yes that fits: 600 MB + 2000 MB is 2600 MB. 2600 MB is 2.6 GB, so it will certainly fit ~ above the 4 GB drive no problem. Equivalently we might say that the 4 GB journey has an are for 4000 MB.

Alice has 100 little images, each of i m sorry is 500 KB. Exactly how much space do they take it up in its entirety in MB?show
Your ghost hunting team is recording the sound within a haunted jajalger2018.org classroom for 20 hrs as MP3 audio files. About how lot data will certainly that be, express in GB?show
MP3 audio takes up around 1 MB every minute. 20 hours, 60 minutes/hour, 20 * 60 returns 1200 minutes. So that"s about 1200 MB, i m sorry is 1.2 GB.

## Alternate Terminology: Kibibyte Mebibyte Gibibyte Tebibyte

It"s convenient within the computer to organize points in teams of strength of 2. For example, 210 is 1024, and also so a program could group 1024 items together, as a sort of "round" number of things in ~ the computer. The ax "kilobyte" above refers come this group size that 1024 things. However, people also group things by thousands -- 1 thousand or 1 million items.There"s this trouble with the word "megabyte": go it mean 1024 * 1024 bytes, i.e. 220, i m sorry is 1,048,576, or does the mean exactly 1 million, 1000 * 1000. It"s just a 5% difference, however marketers have tendency to prefer the 1 million interpretation, because it makes their hard drives etc. Show up to hold a small bit more. Also, the distinction grows larger and larger for the gigabyte and also terabyte sizes. In an effort to settle this, the terms "kibibyte" "mebibyte" "gibibyte" "tebibyte" have been presented to specifically typical the 1024 based systems (see the Wikipedia short article on kibibytes). These terms execute not seem to have recorded on really strongly for this reason far. If nothing else, remember the terms like "megabyte" have this small wiggle room in them in between the 1024 and 1000 based meanings. Us will never grade off for this distinction. "About a million" will be ours close-enough translate for "megabyte".
