Introduction How does the Internet work? Good question!
- Все тонкости в своих проектах он видит, даже самые крохотные.
- Смотри-ка, Макс, - взволнованно проговорила Эпонина.
- How Does the Internet Work?
The Internet's growth has become explosive and it seems impossible to escape the bombardment of www. Because the Internet has become such a large part of our lives, a good understanding is needed to use this new tool most effectively.
This whitepaper explains the underlying infrastructure and technologies that make the Internet work.
How does the Internet work?
It does not go into great how will the internet work, but covers enough of each area to give a basic understanding of the concepts involved. For any unanswered questions, a list of resources is provided at the end of the paper.
We'll use that as an example of how data travels across the Internet. First, you open your Web browser and connect to our Web site. When you do this, your computer sends an electronic request over your Internet connection to your Internet service provider ISP. The ISP routes the request to a server further up the chain on the Internet.
Any comments, suggestions, questions, etc. Where to Begin?
Internet Addresses Because the Internet is a global network of computers each computer connected to the Internet must have a unique address. Internet addresses are in the form nnn. This address is known as an IP address.
How does the Internet Work? Networks and addresses explained.
IP stands for Internet Protocol; more on this later. The how will the internet work below illustrates two real options markets connected to the Internet; your computer with IP address 1.
The Internet is represented as an abstract object in-between. As this paper progresses, the Internet portion of Diagram 1 will be explained and redrawn several times as the details of the Internet are exposed.
In any case, if you are connected to the Internet, your computer has a unique IP address. It's called ping, probably after the sound made by older submarine sonar systems.
A simple network When two computers need to communicate, you have to link them, either physically usually with an Ethernet cable or wirelessly for example with WiFi or Bluetooth systems. All modern computers can sustain any of those connections. Note: For the rest of this article, we will only talk about physical cables, but wireless networks work the same. Such a network is not limited to two computers. You can connect as many computers as you wish.
If you're using a flavor of Unix, get to a command prompt. Type ping www. The pinged computer will respond with a reply.
The ping program will count the time expired until the reply comes back if it does. Also, if you enter a domain name i.

More on domain names and address resolution later. Protocol Stacks and Packets So your computer is connected to the Internet and has a unique address. How does it 'talk' to other computers connected to the Internet?
Ричард с Максом снабдили его исчерпывающими инструкциями: ему надлежало отправиться в зал, подняться по пандусу в Нью-Йорк; затем, пользуясь фонариком и переносным компьютером, он должен был добраться к северному берегу острова и проверить, находятся ли возле него лодки. Какими бы ни оказались результаты исследования, ему следовало возвратиться прямо в убежище и дать им полный отчет. - Запомни одно, - проговорил Ричард. - Это крайне важно: если ты заслышишь октопаука или солдата, немедленно поворачивай и возвращайся к. И еще: ни при каких обстоятельствах ни один человек не должен увидеть, как ты спускаешься в это подземелье.
An example should serve here: Let's say your IP address is 1. The message you want to send is "Hello computer 5. Obviously, the message must be transmitted over whatever kind of wire connects your computer to the Internet.
Let's say you've dialed into your ISP from home and the message must be transmitted over the phone line. Therefore the message must be translated from alphabetic text into electronic signals, transmitted over the Internet, then translated back into alphabetic text. How is this accomplished?
Through the use of a protocol stack. Every computer needs one to communicate on the Internet and it is usually built into the computer's operating system i. Windows, Unix, etc.
