The Internet is a global network of computers, and the number of people using it is growing every year. The U.S. government began developing a computer network in the 1960s called ARPANET, which was replaced by the NSFNET in 1995. Today, parts of Africa are quickly becoming connected, and mobile phones have contributed to the growth of the internet in the continent. According to the World Wide Web, about 40% of Africans are online. The percentage of people using the Internet in these countries is increasing, and in Tanzania, Uganda and Sudan, more than 50% of their population has access. In Guinea, the figure is seven to 10 percent.
The Internet’s origins are a result of the development of packet switching technology in the 1960s. In the 1980s, this technology enabled time-sharing among computers. The National Science Foundation Network was developed as a new backbone for the new network. As the Internet became more widely used, private funding and international participation in its development encouraged the development of new networking technologies. The result was a global network of computers that shared a single IP address.
The backbone of the Internet is a network of large networks known as Network Service Providers (NSPs) that peer with one another to exchange packet traffic. Each NSP connects to at least three Network Access Points (NAPs). This allows packet traffic to jump from one NSP’s backbone to another. In some regions, like Africa, there are even more NSPs than there are women. In India, where internet penetration is very low, more than 70% of Internet users are men. This reflects the tradition of patriarchy and makes the Internet a highly unwelcoming place to conduct business.
The Internet works because of its backbone. To operate properly, it has to have servers and clients. The clients are laptops and desktops that are directly connected to the internet. The servers, on the other hand, are computers that connect to the network via the Internet Service Provider. All three of these networks are connected to one another through packet routing network. The servers are identified by their IP addresses, while the clients are identified by their domain names.
The Internet works with clients and servers. A client is a computer connected directly to the internet, while a server is a computer that is connected indirectly to the net. The server stores websites and is connected to the Internet using an ISP. An IP address is assigned to a server. Each server has its own domain name, which is the name of a website. So a person’s IP address is the same as their domain name.
There are many different types of information on the Internet. Emails, Web pages, and chat messages are not specialized. Instead, all of them are handled the same way. The open nature of the network allows new applications to run on top of it. For example, Skype allows people to make telephone calls over the Net, using a program that converts speech into data. However, the internet also has many other uses, including the sharing of digital files.
