What is “Zettabyte era” ?


Definition: Zettabyte is a unit of information equal to one sextillion (1021) or, strictly, 270 bytes. (source: define:zettabyte – Google)

The zettabyte is a multiple of the unit byte for digital information. The prefix zetta indicates multiplication by the seventh power of 1000 or 1021 in the International System of Units (SI). A zettabyte is onesextillion (one long scale trilliard) bytes.[1][2][3][4][5] The unit symbol is ZB.

1 ZB = 10007bytes = 1021bytes = 1000000000000000000000bytes = 1000exabytes = 1millionpetabytes = 1billionterabytes = 1trilliongigabytes.

A related unit, the zebibyte (ZiB), using a binary prefix, is equal to 10247bytes.

When we talk about Zettabyte era is worth mentioning:

“In 2016 the world has entered the “zettabyte era”:The Global IP traffic will reach 1.1 zettabytes, or over 1 trillion gigabytes.
By 2020 global IP traffic will reach 2.3 zettabytes” source: The Global Technology Report

Important Points: We are at the dawn of the Fourth Industrial Revolution,
which represents a transition to a new set of systems, bringing together digital, biological, and physical technologies in new and powerful combinations

The Networked Readiness Index 2016 or NRI:

“…The composition of the group of top 10 performers is unchanged from last year. The group consists of a mix of high-income Southeast Asian (Singapore and Japan)
and European countries (Finland, Sweden, Norway, the Netherlands, Switzerland, the United Kingdom, and Luxembourg) as well as the United States. Networked
readiness therefore remains highly correlated with per capita income.
Europe remains at the technology frontier with seven out of the top 10 NRI countries being European. Yet the performance range is wide, with Greece dropping four places to 70th position and Bosnia and Herzegovina closing the group at 97. Several Eastern
European countries—notably the Slovak Republic, Poland, and the Czech Republic—are making big strides, landing spots in the top 50 of the NRI; better affordability
and large improvements in economic and social impacts are contributing to this success in these three countries in a major way. Italy is another notable mover this year,
improving 10 places to reach 45th position as economic and social impacts of ICTs are starting to be realized (up 18 in the global impact rankings).

The Eurasia region continues its upward trajectory, with the average NRI score for the region increasing significantly since 2012. In particular, it is notable that the improvement is observed across all four elements that make up the Index: Environment, Readiness, Usage, and Impact. The region is led by Kazakhstan, which The Global Information Technology Report 2016 | xiii Executive Summary continues on its positive trajectory of recent years to land in 39th position this year. Leading the Emerging and Developing Asian economies in 2016 is Malaysia, which continues to perform strongly and moves up one spot to 31st position overall; this performance is supported by a government that is fully committed to the digital agenda. The top five in the region in terms of overall ICT readiness remain China, Malaysia, Mongolia, Sri Lanka, and Thailand, as in 2015. The group of Emerging and Developing Asian countries has been both moving up and converging since 2012. Individual usage in the region is still one of the lowest in the world, but has been growing strongly in recent years. The performance range of countries in the Latin America and Caribbean region remains widely dispersed with almost 100 places between Chile (38th) and Haiti (137th). There was no clear trend from 2015 to 2016 in terms of relative performance, with Chile and Haiti staying put; of the remaining group, half of the countries improve their ranking and the other half drop. Considering the absolute NRI score, however, the region has been moving up and converging since 2012. In order to foster the innovation forces that are key for thriving in the digitized world and the emerging Fourth Industrial Revolution, many governments in the region will urgently need to reinforce efforts to improve the regulatory and innovation environment in their countries. The UAE (26th) and Qatar (27th) continue to lead the Arab world when it comes to networked readiness. The MENAP region (Middle East, North Africa, and Pakistan) is home to two of the biggest movers in this year’s rankings: Kuwait (61st, up 11) and Lebanon (88th, also up 11). In both cases, individuals are leading the charge with the business sector catching up and strongly contributing to the successful performance. Although governments are lagging behind in terms of digital adoption (81st in Kuwait, 124th in Lebanon), the business community in both countries is registering an increased weight on ICTs in government vision and efforts to improve the regulatory environment. This year’s NRI also sees several sub-Saharan African countries among the top upward movers, including South Africa (65th, up 10), Ethiopia (120th, up 10), and Côte d’Ivoire (106th, up 9). Leadership in terms of digital adoption is coming from different groups of stakeholders. Although efforts are very much government-driven in Ethiopia and Côte d’Ivoire, the business sector is providing the most momentum in South Africa. Going forward, the largest barriers to tackle for Côte d’Ivoire will be infrastructure and affordability; reversing the trend of a deteriorating business and innovation environment for South Africa; and individual usage and skills for Ethiopia…”
