What is intranet ? Types of internet ?

An intranet is a main network that is often found in a single enterprise. It usually consists of several interconnected local area networks and also uses these leased lines which have an extensive network network.

Generally speaking, only computers with one or more gateways in an intranet are connected to the external Internet.

The main function of an intranet is to share information and computing resources of a company among employees only. Whereas intranet can also be used for teleconference between work groups.

The same intranet uses TCP/IP, HTTP, and other Internet protocols. That’s why it usually looks like a private version of the Internet.

1- What is the difference between Internet and Intranet?

Here you will know what is the difference between Internet and Intranet.

2- Meaning of Internet

The Internet is a global network that establishes a connection and provides transmission to many different computers.

It uses both wired and wireless mode of communication to send and receive any type of information such as data, audio, video etc. Often the data travels by “fiber optic cables”, which are carried by the telephone companies themselves.

In today’s time, priority is used by all the people in the network to get information, for communication, and to transfer data. It is a public network using which computers can easily connect and relay with each other. It provides users with an excellent source of information.

3- Meaning of intranet

An intranet is a part of the Internet that is privately owned by an organization. It connects all your computers and provides access to all your files and folders within the network.

In addition, there is a firewall that surrounds the system, preventing unauthorized users from accessing the network. Only authorized users have permission to access this network.

Whereas, intranet is used to connect computers and to transmit data. That too within a company’s network. It is a secure method of sharing details, content, and folders as the network is very secure and restricted, within the organization itself.

4- What is the difference between Internet and Intranet?

Where the Internet provides unlimited information that can be viewed and accessed by anyone, in an intranet, data is transmitted only within the organization.
Internet can be accessed from anywhere and everywhere, whereas Intranet can only be used by authenticated users.
While the Internet is not owned by a single or multiple organizations, an intranet, being a private network, belongs to a single firm or institution.
Internet is a public network therefore accessible to all, whereas intranet is a private network hence not available to all.
Intranet is more secure than internet.

5- How does the Internet work

In the Internet, computers are connected to each other through small networks. Whereas these are connected with the Internet backbone through network gateways.

Whereas all computers communicate with each other on the Internet via TCP/IP, which is a basic protocol (ie set of rules) of the Internet.

TCP/IP (Transmission Control Protocol/Internet Protocol) manages all transmissions happening in the internet no matter what the data/files/documents are, but to do this by breaking them into smaller chunks of data/files/documents which is called a packet or datagram.

Each packet contains the address portion of the actual data, i.e. the destination and source addresses are up to 1500 characters long.

6- Functions of TCP and IP

1. The job of TCP is to break these messages into small packets that are transmitted over the Internet and then later reassembled. Those small packets in the oringinal message that are received. through the Internet.
2. The job of IP is to handle the address part of each part, so that the correct address of the data can be transmitted. Each gateway checks this address of the network to see where the message is being forwarded.

7- History of internet

Talking about the history of the net, in 1969, it used to take its first step in the world, and when and with the change of technology, it went ahead and now B is not taking the name of stopping. Know a little more.

So let us further know the history of internet.

1- Internet originated from ARPANET (ADVANCE RESEARCH PROJECT AGENCY NETWORK).

2- ARPANET was part of America’s Department of Defense in 1969.

3- Initially this network was created for the sender through the secret letter computer, its name was ARPANET.

4- This idea was used to connect five American university computers in Startup. By the decade of 1972, it was connected to 23 nodes of the world and different countries of the world, which was later named Internet.

5- Initially, this network was used as a private network, later it was reached and changed throughout the year and now you are reading my knowledge of what is internet and history of internet through this internet. . Were.

9- History of internet in india

Internet was first used in India on 15 August 1995. This service was provided by VSNL (Videsh Sanchar Nigam Limited), the largest telecom company at that time. After this, it brought some changes in India like this.

Shuddha was transported in big cities.
1996 Email site named Rediffmail was started in India.
Bharata’s first cyber cafe opened in Mumbai in 1996.
1997 A site like Noukri.com was created in India, today everyone knows it.
1999 Hindi portal “Webdunia” was launched.
Till the 2000s, the Technology Act 2000 came into force in India.
Yahoo India and MSN India were also started in the decade of 2000.
In 2001 online train website irctc.in was started.
Just as there are two sides of the indicator, in the same way everything has its advantages and disadvantages, in the same way the Internet also has its advantages and disadvantages.

10- Types of internet

There are several types of Internet connections that allow you to connect a personal electronic device to the Internet. All these connections use different hardware and each has a different range of connection speeds.

As technology changes, faster internet connection is needed to handle such changes. That’s why I thought why to tell about the type of internet connection so that you can get to know about all these options.

11- What is Dial-Up Connection (Analog 56K)

A dial-up connection is the most basic form of Internet connection. It consists of a telephone line connected to multiple users (as opposed to a dedicated line) and connected to a PC that has Internet access.

Dial-up access is very cheap but equally slow. A modem (internal or external) connects with the Internet once the computer dials a phone number.

In this, the analog signal is converted, through a modem, into digital and then sent to a land-line service via a public telephone network.

Telephone lines can be of varying quality and their connections can sometimes be poor. It regularly experiences a lot of interference and this affects its speed, which ranges from about 28K to 56K.Since a computer or other device shares the same line of telephone, both cannot be active at the same time.

12- What is DSL Connection

The full form of DSL is Digital Subscriber Line. This is an internet connection that is always “on”. It uses 2 lines so that your phone is completely free when your computer is connected.

DSL is a wired connection that transmits data via traditional copper telephone lines that are already installed in homes and businesses.

You don’t even have to dial any number to be connected to the Internet. DSL uses a router to transport data and the speed of its connection depends on the service, which ranges from around 128K to 8 Mbps.

The speed and availability of DSL service depends on whether your home or business is far away and you have access to a telephone company.

13- What is Cable Connection

Cable provides internet connection through a cable modem and it operates through cable TV lines.

Uploading and downloading have different transmission speed. Since coaxial cables provide more bandwidth than a dial-up or DSL telephone lines, this is where you get faster access.

Cable connection speeds range between 512K to 20 Mbps.

14- What is Fiber Connection

This fiber connection has a fast-fiber optic cable that goes straight to your home or office and gives you a stable, efficient and reliable connection that compares to hybrid copper and fiber systems.

It is capable of supporting broadband speeds of up to 1Gbps, so the speed allows it to play an HD TV program in just five seconds.

Fiber optic technology converts electrical signals that are being data into light and sends the same light through transparent glass fibers the same diameter as a human hair.

Fiber transmits data at very high speeds, much higher than current DSL or cable modem speeds, typically in the tens or hundreds of Mbps. This FTTP connection is not shared with anyone. At the same time it is a very valuable option.

15- What is Wireless Connection

Wireless, or Wi-Fi, as the name suggests, does not use telephone lines or cables to connect to the Internet. Whereas it uses radio frequency.

The wireless connection is also always on and can be accessed from anywhere. The coverage areas of wireless networks are gradually increasing. Whereas its speed range is from 5 Mbps to 20 Mbps.

16- What is Wireless DIA (Direct Internet Access)

Dedicated Internet access means that a specified amount of bandwidth is specified for your use only. This is a dedicated amount which is for your use only.

Here you are not sharing anything with anyone but you must have a direct connection with the Internet Superhighway.

Whereas the speed of another internet connection also depends on how many people are connected to that internet connection but it doesn’t matter because dedicated bandwidth is already provided in it.

17- What is Satellite Connection

Satellite accesses the Earth’s orbit through the Internet via a satellite. In this, since the signal has to travel such a large distance from the earth to the satellite and back again, it provides a delayed connection Here’s a comparison of cable and DSL. Satellite connection speeds range from 512K to 2.0 Mbps.

18- What is cellular or mobile technology connection

Cellular technology provides wireless Internet access through cell phones. Speeds vary by service provider, but the most common are 3G and 4G speeds.
Here 3G describes a 3rd generation cellular network whose mobile speed is around 2.0 Mbps.

Similar to the cellular wireless standards, 4G means the fourth generation. Although 4G aims to achieve a peak mobile speed of around 100 Mbps but in reality it is currently available only up to 21 Mbps.

Whereas 5G has so far been available in only a few locations and is mostly in the testing phase.
