Summary of Unidades: bit, byte, kilobyte, megabyte, gigabyte, terabyte, petabyte, exabyte y zettabyte

00:00:00 - 00:10:00

This video explains the different units used to measure digital storage, starting with the smallest unit, a bit, and progressing to larger units like bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, exabytes, and zettabytes. The speaker notes that understanding these units is essential for purchasing appropriate storage space for one's data. They also provide examples of how much data can be stored in each unit, such as a library requiring roughly a gigabyte of storage, and the entire internet being measured in exabytes. The sequence of units represents the complete scale for measuring digital storage.

• 00:00:00 In this section, the transcript explains the importance of measuring the size of information and introduces different units used for this measurement in computing. The fundamental unit of digital information is the bit, which signifies whether something exists or not, with 1 and 0 respectively. However, bits are difficult to handle and so they are grouped into bytes. A byte consists of 8 bits and can describe a variety of language characters, symbols, and numbers. The size of a stored file is measured in terms of bytes or one of several higher order units such as kilobytes, megabytes, gigabytes, terabytes, petabytes, exabytes, and zettabytes, which each represent progressively larger quantities of bytes. Understanding these units is crucial in purchasing an appropriate amount of storage space for one's data.
• 00:05:00 In this section, we learn about the different units of measurement for digital information, starting with the smallest unit, a bit, which is either a 0 or 1. Eight bits make up a byte, which can be equivalent to one human character. Groups of 1,024 bytes, or 1024^2 bytes, make up a kilobyte (KB) and a megabyte (MB), respectively. A gigabyte (GB) is approximately a billion bytes, and a terabyte (TB) is approximately a trillion bytes. Beyond that, there are petabytes (PB), exabytes (EB), zettabytes (ZB), and yottabytes (YB). These units are necessary because today's technology can store such vast amounts of data. For example, a library of 1,000 books would need roughly a gigabyte of storage. Petabytes of data are found in places like university or bank data centers, with the entirety of the internet being measured in exabytes.
• 00:10:00 In this section, the speaker explains the sequence of units used to measure digital storage: bit, byte, kilobyte, megabyte, gigabyte, terabyte, petabyte, exabyte, and zettabyte. The speaker notes that a petabyte is almost a billion books, and is followed by exabytes which are a thousand petabytes, and then zettabytes which are a thousand exabytes. This sequence represents the complete scale for measuring digital storage.
