The Internet is a global computer network system, sometimes called a net. With permission, users of one computer can receive information from another computer (and in some cases, another computer). Named the US Government’s Advanced Research Projects Agency (ARPA) in 1969, it was originally called ARPANet. The original goal was to create a network where research computer users at one university could “talk” with computer research at another university. Another advantage of the ARPANet project is that the message can be directed or directed in multiple directions so that the network will continue to function even if part of the network is damaged during a military attack or another disaster. You can do it.
Now, the Internet is a public facility, collaborative and independent that you can access hundreds of millions of people throughout the world.
How the Internet works
Physically, the Internet uses some of the total resources of existing public communication networks. Technically, what sets the Internet apart is the use of several protocols known as the Transmission Control Protocol / Internet Protocol (TCP / IP). Two adaptations of new Internet technologies, intranet and extranet, use the TCP / IP protocol.
The Internet can be viewed as two main parts: network protocols and hardware. Protocols such as the TCP / IP suite have rules that the device must follow to complete a task. Without these general rules, machines cannot communicate.
The protocol also converts alphabetical text messages into electronic signals that can be sent over the Internet and then converted into easy-to-read alphabetical text.
Other types of hardware include satellites, radios, cell towers, routers, and servers.
Different types of hardware are connected to the network. Devices such as computers, smartphones, laptops and clients are the endpoint, and servers are the machines that store information. The transmission channels that exchange data are radio signals from satellites or towers of 4G cell phones or cell phones, or physical lines such as cables or fibre optics.
The process of transferring information from one device to another depends on switching packets. Every computer connected to the Internet is given a unique IP address which helps identify the device. When one device tries to send a message to another, the data is sent over the Internet in an organized package. Each package is given a port number to connect to the endpoint.
Packages with unique IP addresses and port numbers can be passed from alphabetical text to electronic signals by moving the OSI model layer from the top application layer to the bottom physical layer. The message is then sent over the Internet and received by the Internet Provider (ISP) router. The router searches for the destination address assigned to each package to determine where to send it.
Eventually, the package reaches the client and retreats from the physical layer below the OSI model to the top layer of the application. During this process, routing data (port number and IP address) is removed from the packet, so the data is transferred with alphabetical text to complete the sending process.
ARPANet, the pioneer of the Internet, was first used in 1969.
Internet communication improved in 1989 with the creation of the Hypertext Transfer Protocol (HTTP), which allowed multiple computer platforms to connect to the same Internet site. In 1993, the Mosaic Web Browser was created.
The Internet has been growing and evolving over the years. For example, IPv6 is designed to anticipate a significant future expansion in the number of IP addresses available. In a related development, IoT is a growing environment that can provide a unique ID (UID) for almost any entity or object and has the ability to automatically transmit data over the Internet.
The social influence
The social influence of the net can be seen as positive and negative. On the other hand, society asserts that the Internet increases the risk of isolating, separating, and withdrawing from society due to emotional reactions that I know as FOMO, or fear of it. On the other hand, people believe that the Internet has a greater impact on society, saying it increases public engagement, community, and relationship strength.
Whether positive or negative, the net has changed the way society communicates and interacts. An example of change is my increasing personal growth and declining community that determines work, family and work. They now make social connections based on your interests, job and personal values. Community created by people who were not just over the internet, but also through the Internet and the online environment are made and stock. Social networking sites such as Facebook and LinkedIn as a platform that is perfect for companies and individuals who want to business with various types and communication with other people.
The benefits are:
Unlimited access to information, science and education.
Improve communication, connection and sharing capabilities.
Ability to work from home, collaborate and access the global workforce.
Opportunity to sell and earn money as a company or individual.
Access to unlimited entertainment resources such as movies, music, videos and games.
Ability to increase the impact of messaging by allowing charitable organizations and other organizations to reach a larger audience and increase the number of donations.
Internet of Things (IoT) access. This allows you to connect and control your home appliances and devices from your PC or smartphone.
Ability to store data easily and share files with cloud storage.
Ability to quickly monitor and control personal accounts such as bank accounts and credit card invoices.
