Internet:
The Internet is the giant network that connects millions and millions of the computer in the world, so any computer can communicate with any other computer as long as they are connected to the Internet.
It is a massive network of networks, a network infrastructure, it is the system of connected computers around the whole world that allows sharing information and data via various types of platforms or various types of media. In easy language it called the “Net” net of Computers in which user can transfer their information.
The Internet is becoming the town square for the global village of tomorrow - Bill Gates (Co-founder of Microsoft Corporation).
When Was the Internet Invented?
The Internet was started in the year 1969 in ARPA(Advanced Research Projects Agency) the United States Government Agency, First, they give a name to that network ASPANet. That goal is to create a network that would allow peoples to research at one university to another university. The design of ASPANet benefit was because it was Routed or rerouted in more than one direction, so if any disaster coming, any war or any of that parts were destroyed the network could continuously works.
Today, the Internet is a public, cooperative and self-sustaining facility accessible to billions of peoples worldwide.
Internet is that infrastructure that You can share your life on Instagram Story, Tweeter, Facebook, stream Outcast on Hotstar, Amazone Prime, Netflix, Message your Friend Who lives anywhere in this world, Lets you order Amazone and search the web for the world’s most beautiful place for a holiday.

How big is the Internet?
One measure is the amount of information that courses through it: about 121694 petabytes, 121694x1015 bytes per month and total That is equal to 50,000 two-hour SD movies per sec.
It takes some wiring up. Thousands of miles of Optic fiber cables (Submarine Cables) spread in the whole world from under the sea floors to connect islands and continents.
About 300 Optic fiber cables (Submarine cables), the deep-sea variant only as thick as a garden hose, underpin the modern Internet. Bundles of Hairly-thin Submarine cables that carry data equal to 3x108 m/s (Speed of Light).

How many peoples use the Internet worldwide.
According to Statista, More than 4.0 billion of users are using the Internet. This is more than half of the world population use the Internet. In China having the biggest online population ar 829 million users, India 560 million, USA 239 million users use the Internet. So Population of the Internet is very High

How Internet work?
Internet Have major two parts Hardware and protocols, protocols need as much as need hardware because without regulations devices would not able to do their work or not able to communicate. The protocol used for transmitting data and that convert numbers to any kind of message or data or design.

Hardware that is the second component, In hardware everything in your computer or mobile phone that used to give access to mobile the Internet to the capable to carry information from one to another device the other hardware also includes like radios, Mobile towers routers servers satellite, cables.
That different types of hardware connect with a network to your devices like Smartphones, Mobile phones, computers, laptops, television like ending points. When devices that store the information, Those are the servers.
The transmission line that transfers the information or data wireless signals from satellites or cellular towers or connects to any cables like fiber optics cable.
Each and Every computer or any device who connected on the Internet have their stipulated unique Internet protocol address (IP address), that allows devices to identify.
Internet Protocols :
The Internet works through the many protocols like...
- Internet Protocol (IP)
- Transport Control Protocol (TCP)
- Transmission Control Protocol (TCP)
- Address Resolution Protocol (ARP)
- Reverse Address Resolution Protocol (RARP)
- Internet Control Message Protocol (ICMP)
- User Datagram Protocol (UDP)
- Post office Protocol (POP)
- Simple mail transport Protocol (SMTP)
- File Transfer Protocol (FTP)
- HyperText Transfer Protocol (HTTP)
- HyperText Transfer Protocol Secure (HTTPS)
- Telnet
- Gopher
The process of transfer the data one device to another device on packet switching.
When one device sends the data to another device, the data sent through the Internet in the form of organizable packets. Each and every
Packets entrusted a port number that will connect it to its receiver point.
For better Explanation see this diagram
A packet has both a stipulated IP Address (Internet Protocol Address) and a unique port number. That can be transferred the data in numerical form (Encrypted) into Electronic signals by traveling via the layers of Open System Interconnection model (OSI Model)
From the layer seven Application layer to layer one Physical Layer. The data sent on the Internet that is recovered by the Internet service provider (IPS). Internet Service Provider’s router will look into the destination of the data entrusted address to each pocket and laid down where to send it.
How Router know where to send data?
In Internet, Each and every Computer or Devices have their own unique IP Address (Internet protocol address, So router check, that IP Address And find location or destination of the Endpoint device, But every router does not need to check every IP Address, Just Outbound link need to find, it means Which one of those neighbors, each packet to. Internet Protocol Address (IP Adress) can be divided into two parts, A network prefix and a host identifier.
If IP Address Have 192.52.39.55 it can be divided into Network
Prefix:192.52
Host Identifier:39.35
All networked devices connected to the Internet via a single connection like College campus or Any company that all share the same network prefix.
Router will send all packets from 192.52.**.** to the same location so instead of searching billions and billions of IP Addresses, the router will track less than a million IP Addresses.
Also, Every country has its oven servers, routers for security reasons, If any potential high-security data have those data save in this server so that data not going outside and maintain national security.
In India, National Internet Exchange of India (NIXI) monitors that servers, NIXI is showing transfer traffic to inside country, so data is not going outside and well maintain privacy and security.

How can you trace servers?
You can trace your IP Address and easily see where your data going when you send or You search anything that time which servers are connected.
For example you search google.com So that time which servers are connected from your computer or any other devices.
Step 1: To trace IP Address in your computer you just open Command prompt (For open Command Prompt You can go to search bar and type command prompt or Press Windows key+R And write cmd )
Step 2: Write "tracert" google.com (You can type any website name here)
Step 3: Go to https://www.iplocation.net/ this website to locate your IP Address
Step 4: Write your IP Address
Step 5: You can see all the servers through this IP Locator.
How do networked computers figure out Internet Protocol Address based on domain names?
When we looking up the settled IP address like www.youtube.com, Computers resolve an IP Addresses via DNS (Domain Name System), That have reserved IP Address so That mapping from domain name to Internet Protocol Addresses (IP Addresses).
To resolve an IP address, the computer first checks its local Domain Name System cache, which stores the IP address of web sites it has visited recently.
It checks IP Address available or not, If it can’t find the IP Addresses that means that IP Address Expired in there record, it queries the Internet Service Provider’s Domain Name System, servers which are dedicated to resolving IP addresses.
If the Internet Service Provider’s Domain Name System servers can not find resolve the IP address, they query the RNS ( Root Name Server’s), which can resolve every domain name for a given top-level domain. Top-level domains are the words to the right of the right-most period in a domain name like .com, .net, .org, .co.in, .in. These are top-level domains.

Use of the Internet:
Communication:
The Internet is a very cost-effective communication method at this time, On the Internet so many services, are available like...
- Email service
- IRC (Internet Relay Chat)
- Audio-video conferencing service
- Social Media service
- Instant Messaging service
Knowledge
- Any kind of information available
- Books
- Study Research
Internet Forums
Financial Services
Worldwide News
For searching Jobs
And so many uses have, we can find anything using the Internet.
