Excerpt:
> Perhaps someone might ask, if there is no organization or individual managing the Internet, who pays for its expenses? The answer is that no one supports the entire cost of the Internet, nor is there a company or individual that charges fees to all networks or users connected to the Internet. The funding for the Internet is borne by each member network independently. Higher education institutions must pay for their own campus network costs. When different networks interconnect, each network pays for its own interconnection costs. Universities or companies must pay for their interconnection with regional networks, while regional networks pay for their interconnection with national networks, and so on.
1.4 Services Provided by the Internet
Before engaging with the Internet, it is essential to understand what motivates you to enter its world—is it to bypass the "Cape of Good Hope" and freely communicate with friends, sharing warmth and care, without the need for a desert camel bell to obtain what you need, or simply out of curiosity for something new? Let’s first explore what the Internet can actually do and what services you truly need. The services provided by the Internet are basically categorized as follows.
1.4.1 Electronic Mail
Electronic Mail (Electronic Mail, commonly referred to as E-mail) is perhaps the most widely known service on the Internet. It is a communication method for exchanging information over computer networks. Compared to traditional postal services, Internet-based electronic mail offers advantages such as convenience, speed, and cost-effectiveness. With E-mail services, users can send the same email to multiple recipients simultaneously and transmit information including text, sound, images, and graphics. In summary, with E-mail, users can not only send and receive traditional letters but also communicate and seek help across geographical and national boundaries. The prerequisite for using Internet-based electronic mail services is having an E-mail account (email address), which is established by the E-mail service provider. Essentially, it is a dedicated disk space allocated on the computer connected to the Internet by the provider, specifically for storing incoming and outgoing emails.
