Explain Network Information Technology – As you read this article, you are contributing to history. Over the past fifty years, the technology and functionality of the Internet have transformed to become convenient systems that we use in our daily lives.
But as you might have guessed, the internet wasn’t always like this, nor was it so popular. In fact, in 2000, only 52% of US adults said they used the Internet; but in 2018, that number jumped to 82% [1].
Explain Network Information Technology
From the inquiry that brought you here in the first place: “how does the internet work?” to online shopping and communicating with family and friends, the Internet has completely changed the way we live, work together and learn. But where did it all start? And how did the Internet evolve into the ubiquitous system we know today?

To fully understand how the Internet works and how we got here, we need to start at the beginning.
On October 29, 1969, an organization called ARPANET (Advanced Research Projects Agency) launched the first iteration of the Internet (also known as ARPANET), connecting four mainframe computers at the University of Utah, UCSB, UCLA, and Stanford Research Institute [2]. ].
When this network of computers was connected, universities could access files and transfer information from one institution to another, as well as internally.
As the researchers developed the system, they continued to connect computers from other universities, including MIT, Harvard and Carnegie Mellon. ARPANET was eventually renamed “the Internet”.
What Is Network Transformation?
In its earliest days, the Internet was only used by computer experts, scientists, engineers, and librarians who had to learn a complex system to use it, but as technology improved and users adapted, it became an essential tool for people around . The globe.
The 1970s were a period of major transition to the Internet. Electronic mail was introduced in 1972, libraries across the country were connected, and above all, the exchange of information became more seamless thanks to the Transport Control Protocol and the Internet Protocol (TCP/IP) architecture.
The invention of these protocols helped standardize the way information is sent and received over the network, making it more consistent no matter where or how you access the Internet.
Then, in 1986, the National Science Foundation took Internet development to the next level by funding NSFNET, a nationwide network of supercomputers.
Media And Information Literacy
These supercomputers laid the foundation for personal computing, bridging the gap between computers used only for academic purposes and computers used to perform everyday tasks.
In 1991, the University of Minnesota developed the first user-friendly Internet interface to facilitate access to files and information on campus. The University of Nevada, Reno continued to develop this user-friendly interface by introducing search and indexing features.
As the development of the Internet continued to evolve and shift focus, the National Science Foundation ceased sponsoring the Internet Backbone (NSFNET) in May 1995.
This change removed all restrictions on commercial use of the Internet and ultimately allowed the Internet to diversify and grow rapidly. Soon after, Delphi was joined by AOL, CompuServe, and Prodigy to offer commercial Internet services to consumers.

The debut of WiFi and Windows 98 in the late nineties marked the technology industry’s commitment to developing the commercial element of the Internet. This next step gave companies like Microsoft access to a new audience, consumers (like you).
Flash forward to today. Approximately three billion people now use the Internet, many of whom use it every day to help them get from point A to point B, catch up with loved ones, collaborate at work, or learn more about important issues like how . is the internet working [3]
As technology changes and the Internet enters almost every aspect of our lives, even more people are expected to use it. In 2030, researchers predict that there will be 7.5 billion Internet users and 500 billion Internet-connected devices [4].
Now that you have some idea of the evolution of the Internet, let’s tackle the question: “how does the Internet work?”

The Internet is a global computer network that transmits various data and media through interconnected devices. It works by using a packet routing network that follows Internet Protocol (IP) and Transport Control Protocol (TCP) [5].
TCP and IP work together to ensure that data transmission over the Internet is consistent and reliable, no matter what device you use or where you use it.
When data is transmitted over the Internet, it is distributed in messages and packets. Data sent over the Internet is called a message, but before it is sent, it is divided into small pieces called packets.
These messages and packets travel from one source to another using Internet Protocol (IP) and Transport Control Protocol (TCP). IP is a system of rules that govern how information is sent from one computer to another over an Internet connection.

Using a digital address (IP address), the IP system receives additional instructions on how the data should be transmitted.
The Transport Control Protocol (TCP) works with IP to ensure that data transmission is reliable and trustworthy. This helps ensure that no packets are lost, that packets are reset in the correct order, and that there are no delays that negatively affect data quality.
Wondering how the internet works from browser launch to search results? We go through the process step by step [7] [8] [9].
Step 1: Your computer or device is connected to the network via a modem or router. Together, these devices allow you to connect to other networks around the world [6].
What Is Network Management?
Your router allows multiple computers to join the same network, while a modem connects to your ISP (Internet Service Provider), which provides you with cable or DSL Internet.
Step 2: Enter a web address known as a Uniform Resource Locator (URL). Each website has its own unique URL that tells your ISP where you want to go.
Step 3: Your request is sent to your ISP, which connects to several servers that store and send data, such as a NAP (Network Access Protection) server and a DNS (Domain Name Server).
Your browser then looks up the IP address for the domain name you entered into your search engine via DNS. DNS then converts the text-based domain name you type into the browser into the number-based IP address.
What Is Network Architecture?
Step 4: Your browser sends a Hypertext Transfer Protocol (HTTP) request to the destination server to send a copy of the website to the client via TCP/IP.
Step 5: The server then approves the request and sends a “200 OK” message to your computer. The server then sends website files to the browser in the form of data packets.
Step 6: While your browser resets data packets, the website loads, allowing you to learn, shop, browse and engage.

Philosophers and writers have conceptualized a common repository of world knowledge for centuries. How did we get to the internet we know today?

When you buy a new computer, the first thing you probably try to do is connect to the Internet. To do this, you establish a connection to your router, which receives the data from the Internet and then forwards it to the computer.
Of course, that’s not all: You can then also connect your printer, smartphone or TV to the router so that these devices are also connected to the Internet. Now you have connected different devices through a central access point and created your own network.
In information technology, a network is defined as the connection of at least two computer systems, either by cable or
