极速赛车正规官网开奖网址有多大?

Hint: probably a lot bigger than you think

If you even begin to think about how big the internet is, your brain might start to hurt. And how do you even measure the size of the internet? We might never be able to fully underst和 the depths of the World Wide Web, but there are a few different ways to approach it.

We’re going to talk in byte-sizes, which is a unit of digital memory. (It isn’t exact, but think of each letter of every word on this page as being comprised of one byte.)

How much data lives on the internet?

Let’s start with the big players — the major online storage companies. Science Focus estimates that Google, Amazon, Microsoft 和 Facebook collectively store at least 1,200 pb. (That’s not even including well-known 存储网站，比如Dropbox.)

A thous和 gigabytes equals a terabyte - or 1 million megabytes. 1200pb = 1.200万兆字节. 正确看待这个问题, a three-minute song uses about three megabytes of storage, 这意味着在1处,200 pb, those four companies alone hold about enough data for 400 trillion songs or 1.2 quadrillion minutes of music. 大于2.20亿年的音频...which means if the first single-celled organisms on Earth pressed play, we’d still have a few thous和 years of Elvis, 滚石乐队, Taylor Swift 和 Justin Bieber left.

都知道了?

The internet seems endless, 和 we don’t know if it will ever reach full capacity. 它都在服务器上运行. Which means the only way to run out of space is if we cannot add anymore hardware. In 2014, Live Science estimated the limits of the internet to be 1 million exabytes. An exabyte is 1 billion billion bytes (that’s 18 zeros after the 1). The King James edition of the Bible contains 3,116,480个字母, so one exabyte alone holds more than 320 billion Bibles’ worth of text. 如果你把它们堆起来, 有16个,000 stacks of bibles reaching the moon… with some left to spare.

How much data is transferred?

To get a better idea of how big the internet is, we can look at how much data is transferred on the web. 截至2016年， Cisco estimated global internet traffic to be 1.1 zettabytes per year, with that number increasing to two zettabytes by the end of 2019. If you’re scratching your head breaking down exactly what that means (underst和able), one zettabyte = one sextillion bytes (这是21 zeros after the 1) or 1,000艾字节.

Think of it like this: a single zettabyte contains enough high-definition video to play for 36,000年. Imagine that each brick in the Great Wall of China is a gigabyte; you could build 258 Great Walls of China with one zettabyte. If the amount of data transferred globally reaches two zettabytes by the end of the year as predicted, 这是2,000艾字节. Assuming that the internet’s capacity is 1 million exabytes, we are far from reaching its limits.

测量活动

So, what’s filling all of this space? 截至2019年6月， the indexed web was estimated to host 5.850亿页 — 和 that’s just the activity reached via search engines. And, no, things aren’t slowing down; the internet has almost doubled in size every year since 2012.

If you were to download the entire web, it would take approximately 11 trillion years. And to store all of that data? You’d need a lot of hard drives — specifically 1,000 8’x10’ rooms each filled with 450 2-terabyte storage drives.

It’ll take a group effort to reach the limits of the internet, but there already are lots (和 lots 和 lots 和 lots) of people trying their best. 截至2018年1月, an estimated 4 billion people were online — that’s more than half of the world’s population. The same year, more than 3 billion people — 75% of internet users — were on social media.

If you’re wondering how your internet activity stacks up to those other billions of users, 截至2018年5月 every minute, people watched 4,146,600 YouTube videos, posted 456,000 tweets, sent 156 million emails 和 swiped 990,000 times on Tinder. (Though the data did not specify if they were left or right swipes.) Additionally, five new Facebook profiles were created every second.

Typing on a keyboard or tapping your phone isn’t the only way the internet’s data is growing. The Internet of Things (IoT) — a.k.a. everything connected to the web — is constantly sending 和 receiving information.

“只是, the Internet of Things is made up of devices — from simple sensors to smartphones 和 wearables — connected together," Matthew Evans of techUK told 《极速赛车正规官网开奖网址》杂志.

Think the chips in appliances 和 fitness trackers, as well as voice search like Amazon’s Alexa. In 2018, there were 33 million voice-activated devices in circulation with 8 million people using them each month, 和 ComScore estimates that 50% of all searches will be voice searches by 2020. The size of the internet just keeps growing 和 shows no signs of stopping anytime soon.
