美国作业格式：一般的互联网环境和接入的决定因素
internet环境基本上是具有网关、路由器、桥梁等的网络的逻辑集合。这些复合层结合在一起是完全功能的单元，用于与特定的协议和过程进行通信。internet使用的客户端服务器网络形式通常被认为是最可用的一种网络形式，而且大多数国家都映射到复杂的互连结构。据统计，世界上大约有40%的人口使用互联网，尽管速度不同。根据1995年的一项过去的估计，只有不到1%的用户使用因特网。因此，仅在1999年至2013年的最近几年里，可访问性的数量就增加到了10%左右。

现在有这么多的用户，互联网统计和记录似乎表明，大约60%的人口仍然没有适当的互联网接入。所提出的关注是关于可访问性。可访问性是这里的一个主要问题，因为个人和组织与internet的连接受到可访问性问题的阻碍。据估计，大约有40亿人无法上网，正因为如此，他们失去了从互联网上获得的许多好处。它们似乎在连通性、金融服务、卫生信息获取等方面受到了影响。全球近四分之三的互联网被20个国家所占据，英国就是其中之一。了解互联网可及性的决定因素将使每个人都能负担得起互联网。
“普及、廉价的互联网接入是联合国可持续发展目标(SDGs)的一部分，各国政府、企业、地方和国际组织以及公民社会成员正在努力让更多的人上网。”然而，正如世界经济论坛(World Economic Forum)一份新报告所解释的那样，这个问题是巨大、复杂和多维的。

The internet environment is basically a logical collection of networks with gateways, routers, bridges and more. The complexes layers that come together are fully functional units that are used for communication with specific protocols and processes. The client server network form of internet use is often cited as the single most usable form of networking, and most countries map unto complex structures of internetworking. It is identified that around 40 percent of the total world population uses an internet connection, although it is of different speed forms. It is assessed in a past estimate made in the year 1995 that less than 1 percent of users used the internet. The numbers in accessibility hence have increased to around ten percent within the last few years alone from 1999 to 2013.

Now with this many users, internet statistics and records seem to indicate that around 60 percent of the population is still without proper internet access. The concerns raised are with respect to accessibility. Accessibility is a prime issue here, as individuals and organizations connection to the internet is hindered because of issues of accessibility. It is estimated that around 4 billion people do not have access to the internet and because of this are missing out on many benefits from the internet. They seem to suffer in terms of connectivity, financial services, health information access and more. Almost three quarters of the world’s internet are occupied by 20 countries and the United Kingdom is one of them. An understanding of the determinants for internet accessibility will hence make internet affordable for everybody.
“Universal, affordable internet access is part of the UN’s Sustainable Development Goals (SDGs), and governments, companies, local and international organizations, and members of civil society are working to get more people online. However, as a new report from the World Economic Forum explains, the problem is big, complex and multidimensional”.
