The internet and intranet are closely related terms. Some individuals may get these terms confused or use them interchangeably. While there are similarities, the internet and intranet are used for very different purposes.
How Does the Internet Work?
Internet , a system architecture that has revolutionized communications and methods of commerce by allowing various computer networks around the world to interconnect.
By , approximately 4. The Internet is a vast network that connects computers all over the world. Through the Internet, people can share information and communicate from anywhere with an Internet connection. The Internet consists of technologies developed by different individuals and organizations. Important figures include Robert W. The Internet works through a series of networks that connect devices around the world through telephone lines.
Users are provided access to the Internet by Internet service providers. The widespread use of mobile broadband and Wi-Fi in the 21st century has allowed this connection to be wireless. The advent of the Internet has brought into existence new forms of exploitation, such as spam e-mail and malware , and harmful social behaviour, such as cyberbullying and doxxing.
Many companies collect extensive information from users, which some deem a violation of privacy. The Dark Web refers to a series of Web sites that require special decryption and configuration tools to access. It is most commonly used for purposes that require strict anonymity, including illegal sales e.
While the Internet is theoretically decentralized and thus controlled by no single entity, many argue that tech companies such as Amazon , Facebook , and Google represent a small concentration of organizations that have unprecedented influence over the information and money on the Internet.
In some countries, certain parts of the Internet are blocked via censorship. The Internet provides a capability so powerful and general that it can be used for almost any purpose that depends on information, and it is accessible by every individual who connects to one of its constituent networks. It supports access to digital information by many applications, including the World Wide Web.
See electronic commerce. By the early s computer manufacturers had begun to use semiconductor technology in commercial products, and both conventional batch-processing and time-sharing systems were in place in many large, technologically advanced companies.
Host-to-host interactions were envisioned , along with access to specialized resources such as supercomputers and mass storage systems and interactive access by remote users to the computational powers of time-sharing systems located elsewhere. Department of Defense. It connected time-sharing computers at government-supported research sites, principally universities in the United States , and it soon became a critical piece of infrastructure for the computer science research community in the United States.
Tools and applications—such as the simple mail transfer protocol SMTP, commonly referred to as e-mail , for sending short messages, and the file transfer protocol FTP , for longer transmissions—quickly emerged. In order to achieve cost-effective interactive communications between computers, which typically communicate in short bursts of data, ARPANET employed the new technology of packet switching.
Packet switching takes large messages or chunks of computer data and breaks them into smaller, manageable pieces known as packets that can travel independently over any available circuit to the target destination, where the pieces are reassembled.
Thus, unlike traditional voice communications, packet switching does not require a single dedicated circuit between each pair of users. Commercial packet networks were introduced in the s, but these were designed principally to provide efficient access to remote computers by dedicated terminals.
In the United States, Telenet and Tymnet were two such packet networks. Neither supported host-to-host communications; in the s this was still the province of the research networks, and it would remain so for many years.
The ground-based packet radio system provided mobile access to computing resources, while the packet satellite network connected the United States with several European countries and enabled connections with widely dispersed and remote regions. With the introduction of packet radio, connecting a mobile terminal to a computer network became feasible.
However, time-sharing systems were then still too large, unwieldy, and costly to be mobile or even to exist outside a climate-controlled computing environment. A strong motivation thus existed to connect the packet radio network to ARPANET in order to allow mobile users with simple terminals to access the time-sharing systems for which they had authorization.
These terminals, however, had to be connected to other networks in European countries in order to reach the end users. Thus arose the need to connect the packet satellite net, as well as the packet radio net, with other networks. Internet Article Media Additional Info. Article Contents.

Difference Between Network and Internet
A local area network LAN is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. Ethernet and Wi-Fi are the two most common technologies in use for local area networks. The increasing demand and usage of computers in universities and research labs in the late s generated the need to provide high-speed interconnections between computer systems. A report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation. A number of experimental and early commercial LAN technologies were developed in the s.

The network is two or more connected computer which can share resource like a printer, an internet connection, application, etc. It is a collection of computer systems and devices which are linked together using a wireless network or via communication devices and transmission media. The network provides connectivity between computers and devices within a restricted range where only one entity is controlled or authorized to manage the entire system. In this tutorial, you will learn What is a Network?
What Is the Difference Between Internet and Intranet?
Computers and their systems square measure difficult in their approach, and it gets doubly robust once you need to comprehend 2 terms associated with this subject that act already utilized in the regular language, those mentioned adequately during this article square measure Network and net, they will appear totally different from one another, and so they will seem like one another. The most distinction between them comes in their definition; a Network could be a association of 1 or additional computers placed in associate surroundings, and also the Internet is that the relationship of computers connecting them from everywhere the planet. The basic distinction between network and net is that the Network consists of pcs that area unit physically connected and may be used as a private computer yet on share data with one another. Conversely, the Internet could be a technology that links these little and huge networks with one another and builds a additional in depth network. Attention reader!
A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data. An example of a network is the Internet , which connects millions of people all over the world. To the right is an example image of a home network with multiple computers and other network devices all connected. The term network topology describes the relationship of connected devices in terms of a geometric graph.
Беккер молил Бога, чтобы это оказалось неправдой. - Рего… Но… Она пожала плечами и произнесла по-испански: - Девушке возле парка. Беккер почувствовал, что у него подкашиваются ноги. Этого не может. Росио игриво улыбнулась и кивнула на немца. - El queria que lo guardara.
The essential difference between network and internet is that the network consists of computers that are physically connected and can be used as a personal.
Должен быть какой-то другой выход. - Решайте! - крикнул Хейл и потащил Сьюзан к лестнице. Стратмор его не слушал. Если спасение Сьюзан равнозначно крушению его планов, то так тому и быть: потерять ее значило потерять все, а такую цену он отказывался платить. Хейл заломил руку Сьюзан за спину, и голова ее наклонилась. - Даю вам последний шанс, приятель. Где ваш пистолет.
Когда он был уже почти рядом, Сьюзан поняла, что должна действовать. Хейл находился всего в метре от нее, когда она встала и преградила ему дорогу. Его массивная фигура буквально нависла над ней, запах одеколона ударил в ноздри. - Я сказала. - Она смотрела ему прямо в. Хейл наклонил голову набок, явно заинтригованный такой скрытностью.
Это Цифровая крепость. - Вот как? - снисходительно произнес Стратмор холодным как лед голосом. - Значит, тебе известно про Цифровую крепость. А я-то думал, что ты будешь это отрицать. - Подите к черту.
- Я вел себя довольно глупо. Я хотел лично сказать Росио, какое удовольствие получил от общения с ней несколько дней. Но я уезжаю сегодня вечером.
Они в ловушке, шифровалка превратилась в узилище.
Он мечтал о ней по ночам, плакал о ней во сне. Он ничего не мог с собой поделать. Она была блистательна и прекрасна, равной ей он не мог себе даже представить.
Сьюзан пыталась отстраниться, но он не отпускал. ТРАНСТЕКСТ задрожал, как ракета перед стартом. Шифровалка содрогалась.
Поиски ключа не дали никаких результатов. Сьюзан надеялась, что Стратмору не придется долго возиться с отключением ТРАНСТЕКСТА. Шум и мелькающие огни в шифровалке делали ее похожей на стартовую площадку ракеты.
