FutureStarrHow Many Megabits Are in a Gigabyteor
In computing and physics, the unit of information or data is usually given the symbol "bit," short for "binary digit". With 1 bit, everything is possible and nothing is definite. In computing, the 8 bits in 1 byte make up a digit, a number that can range from 0 to 255.
Since most files contain thousands of bytes, file sizes are often measured in kilobytes. Larger files, such as images, videos, and audio files, contain millions of bytes and therefore are measured in megabytes. Modern storage devices can store thousands of these files, which is why storage capacity is typically measured in gigabytes or even terabytes. Not everyone needs Gigabytes of data to live through. If you’re probably on a vacation or a retreat, you might want to have talk, text, and a few Megabytes (MB), for instance, 500MB. So the next time you’re in front of a data plan, a rough usage estimate might make things clear.
Before we visit how many MB in a GB, let’s talk about how many KB in a MB. For ease of calculation, we’ll say there are 1000 kilobytes (KB) in a megabyte (MB) and 1000 MB in a gigabyte (GB), often referred to as a gig of data. That takes care of the math, but what are the real-world implications? Well, we’ve broken down what you can do with different amounts of data. We like to think of them in terms of being small, medium, large and extra-large buckets of data. (Source: ting.com)
Bytes hold a string of bits, typically eight for most computer systems. A bit, short for binary digit, has a single binary value of either 0 or 1 and is the smallest unit of data in a computer system. Memory or storage devices typically store the value of a bit above or below a designated level of electrical charge in a single capacitor. A byte holds its string of bits so they can be used in a larger unit for application or OS purposes.
Additional units of measurement become necessary as the amount of data in the world increases. And it's not going to slow down any time soon. Actual drive capacity may not currently go beyond the terabyte scale, but this will undoubtedly change as storage media technology evolves. (Source: searchstorage.techtarget.com)
