Jump thinking does not belong to the digital age.

The four major characteristics of the digital era are as follows:

1, the volume of data (Volume)

The obvious characteristic of big data is its huge data size. With the development of information technology, the Internet continues to expand, everyone's life is recorded in the big data, the data itself is also explosive growth. The unit of measurement of big data has also gradually developed, and now the measurement of big data has reached EB.

2, Variety (Variety)

In the huge number of Internet users and other factors, the source of big data is very wide, so the type of big data also has a variety. Big data can be categorized into three types by the strength of causality, i.e., structured data, unstructured data, and semi-structured data, which are collectively known as big data. Information shows that structured data accounts for a relatively large proportion of the overall big data, up to seventy-five percent, but the big data that can produce high value is unstructured data.

3, value density (Value)

Big data all value in the characteristics of big data occupies a central position, the total amount of big data data and its value density is inversely proportional to the relationship between high and low. At the same time for any valuable information is extracted after processing the massive amount of basic data. In the booming development of big data today, people have been exploring how to improve the computer algorithms to deal with massive big data, the speed of extracting valuable information this problem.

4, high speed (Velocity)

The high-speed characteristics of big data are mainly reflected in the rapid growth in the amount of data and processing. Compared with traditional media, in today's big data era, the production and dissemination of information has changed dramatically, in the role of the Internet and cloud computing and other ways, big data can be rapidly produced and disseminated, in addition to the timeliness of information, but also requires a rapid response in the process of processing big data, no delay in the input and extraction of data.
