RAM is also usually measured in gigabytes. A tablet may only require 1 GB of system RAM since portable apps typically do not require as much memory as desktop applications.

If you would like to reference this page or cite this definition, you can use the green citation links above. The goal of TechTerms. Understanding what a gigabyte is, and all of its abbreviations, including GB, is important in all of your computing needs.
Most everyone needs a computer or a computing device. You need to know how much storage you will need and shop accordingly. Save my name, email, and website in this browser for the next time I comment.
Why is it important to understand GB? How much does a GB hold? Click Here to Leave a Comment Below. The unit of measurement in storage capacity that follows it is the terabyte TB , which equals 1, GB. Gigabytes are normally used for measuring storage capacity, data transmission speed or random-access memory RAM , with some important differences see the explanation below.
Hard drives, which can hold several hundred GB of data beyond 1, GB, the size is usually measured in terabytes. One byte contains eight bits comprised of a string of 0s and 1s.
These eight bits can hold values, ranging from 0 to Generally, a byte is the number of bits used to encode a single text character. In computing terminology, a gigabyte might denote either a certain amount of physical memory data storage capacity in hard drives and solid-state drives or data transmission speed.
However, it is also used in information technology to specify amounts of RAM memory, namely 10, bytes, leading to some confusion and even lawsuits against drive manufacturers in the United States.
In fact, in IT and computer science, one GB equals 1,,, 10, or bytes. For example, one GB is one billion bytes, and one kilobyte KB is one thousand bytes. 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. The audio on a CD is not compressed, which is why it takes so much more space than the MP3.
The series of bits are represented as spiral path of tiny pits in the silver material in the disk. Imagine that each pit is interpreted as a 0, and the lack of a pit is a 1 as the spiral sequence is read.
