The internet is a combination of computer networks connected together from all around the world. These computer networks use the Internet Protocol to join the computers of private, public, academic, and organizations.
The Internet includes a wide range of information assets and services, such as documents, the world wide web, e-mails, and file sharing. In this article, we provide you with comprehensive information about what is the internet, the history of the internet, and its features, types, advantages, and disadvantages. Stay with us to explore more.
What is Internet?
The Internet is a collection of computer networks that are connected to each other through telephone lines, communication channels, satellites, etc, and use specific rules and protocols called TCP / IP to transmit information and data to each other.
With the essential changes and extraordinary growth that has taken place over the last decade, today the Internet is now one of the most important tools that transfer the communities to the information society. In the Information society, all computer networks, telephones, video conferences, Mobile phones, etc. communicate and exchange information with each other.
History of Internet
In the late 1960s, during the Cold War, the US government decided to invent a way to open lines of communication in the occurrence of a nuclear attack. In the past, there was a control center to do this, which was responsible for transmitting messages.
If one of these centers was blasted, all networks would fail. As a result, the Advanced Research Projects Agency (ARPA) decided to establish a computer network without a control center. And in the early 1990s, the ARPA network became the Internet.
Who Invented the Internet?
Unlike technologies such as telephones, lamps, etc., the Internet is not a specific inventor but has evolved over time. The Internet has been around for more than 50 years in the United States as a government weapon in the Cold War.
For many years, scientists and researchers have used this technology to communicate and transfer data with each other. The Internet Protocol suite was developed in the 1970s by Robert E. Kahn and Vint Cerf which leads the internet to become a standard network.
Types Of Internet
Today, the Internet is an important part of most businesses. With the advancement of technology and the increase of the presence of businesses in cyberspace, the use of the Internet is increasing day by day.
Having an online service is one of the most important factors in the success of businesses. So, before buying your internet service, it is better to have information about the types of internet so that you can select the best service according to your requirements.
There is a variety of ways to connect to the Internet, and each has its own set of characteristics. The following is a brief description of the types of Internet services and their differences from each other:
DSL
DSL stands for Digital Subscriber Line. This service provides a high-speed internet connection using the telephone lines. Because DSL is based on telephone lines, it is the most common type of internet service for home users.
DSL is cheaper than other services, but it is not the fastest type of Internet service on the market. The speed and quality of the DSL connection become reduced as the distance between the user and the switching station increases.
In other words, this service is usually suitable for a location close to the service provider. DSL Internet can easily be accessed where a telephone network is available. This service enables you to use the Internet and telephone at the same time without any hindrance.
DSL is a static Internet service offered by FCP and SRVCO licensees. In the following, we will briefly introduce the types of DSL services.
ADSL
ADSL or Asymmetric Digital Subscriber Line is a form of asymmetric DSL. ADSL is a technology constructed to offer fast speed internet connection using Internet lines than older Dial-Up Internet services.
Asymmetric means that the upload and download speeds are dissimilar in this internet service. Because home users want to download faster than uploading content, the download speed is generally faster than the upload speed.
ADSL internet speed is up to 50 MB / s depending on the bandwidth presented in copper cabling. It should be noted that the speed and quality of ADSL2 + are faster than ADSL. The average speed of ADSL2 + is between 1 MB / s for upload and 24 MB / s for download.
VDSL
VDSL is another type of DSL Internet service, which stands for Very High-Speed Digital Subscriber Line. VDSL is based on cable, not like ADSL, which uses landline telephone lines. You must need to use the cable to use VDSL.
VDSL, like ADSL, is asymmetric and usually has a faster downloading speed than the uploading speed. Providers introduce VDSL bandwidth as a faster and more stable connection compared to other copper-based services such as ADSL. VDSL download speed is ideally 5 times faster than ADSL.
SDSL
SDSL stands for Symmetric DSL and due to its symmetry, its download and upload speeds are the same. The download and upload speeds of SDSL is 2.3 MB / s, while VDSL download speeds are up to 52 MB and upload speeds are up to 16 MB / s.
SDSL is a type of DSL service that does not permit analog telephone service. This means that you either do not have telephone service or need to use a digital telephone or VoIP connection.
Wireless
One way to make use of broadband services is to use wireless communication. As the name shows, this service uses radiofrequency instead of cables and telephone lines like DSL. In addition, Wireless communication provides much more bandwidth and stability than DSL, which reduces installation costs. In the following, we will discuss and explain some major types of wireless services.
Shared Wireless
In a shared wireless Internet service, subscribers can use the frequency bandwidth on the wireless platform without the need for a telephone line or cable. They get access by installing radio equipment in a location that overlooks the service provider’s website. The essential thing about this service is the presence of a radio on the pop-site side and sending the frequency to different subscribers.
Dedicated Bandwidth
Dedicated bandwidth service is provided on a point-to-point basis. It means that for each customer there is a unique radio on the pop-up site and the frequency is sent entirely to one subscriber. The quality and speed of this service have a guarantee for 24 hours a day.
This service is best for organizations and businesses that need unlimited and dedicated Internet to do their communication. The FCP and SERVCO licensed companies also provide this service.
WiMAX
WiMAX stands for World Wide Interoperability for Microwave Access. It means the ability to exchange and use information globally by means of microwaves. WiMAX Internet service provides access for areas that do not have access to fixed cable Internet.
The most vital feature of WiMAX is that it is mobile and not fixed or limited to a specific area or place. WiMAX technology provides the Internet to users on a very huge scale through long-distance towers.
WiMAX works like WiFi but at a very high speed and over longer distances for maximum users. The WiMAX has capable to provide services even in areas where access to wired infrastructure is not possible. This type of internet service also has the ability to beat the physical limitations of traditional wiring infrastructure. This system has two main components: a WiMAX tower and a WiMAX receiver
WiMAX, like Wi-Fi, can connect directly to the Internet by sending a signal from the WiMAX tower via a wired connection. WiMAX transmitters are capable to cover an estimated radius of 2 km while the Wi-Fi range is about 30 m. In other words, WiMAX turns many small scattered hotspots into big wireless hotspots.
FTTH
FTTH stands for Fiber to the Home, which uses fiber optics to get access to high-speed Internet. In this way, the optical fiber is dragged from a head office to the subscriber and enables the subscriber to use the Internet. The difference between this service and other services is the technology.
The whole communication path is made of high-speed optical fibers. The FTTX and FCP license providers can provide FTTH or fiber-optic service within the regulatory framework.
TD-LTE
TDD-LTE stands for Time Division Duplexing – Long Term Evolution. TD-LTE is a permanent wireless service provided by companies with an FWA license. TD-LTE service needs special modems and SIM cards. The SIM card is placed inside the modem and is exclusively responsible for receiving and sending information. TD-LTE does not have ADSL service limits, including location restrictions and the need for a telephone line.
Advantages of this service include high data transfer capacity, reducing installation and operation costs, and allocating dynamic capacity to Uplink or Downlink streams which enhance the user experience.
This technology allows receiving and sending on one frequency bandwidth in different time intervals without dividing the frequency bandwidth. This results in full use of bandwidth capacity to send or receive information and the speed of sending and receiving information can also be enhanced.
Mobile Internet
Mobile service providers now offer cellular network-based Internet to their subscribers over the phone line. The high speed of this service has made it similar to other types of Internet services. The WWW connection is established without the need for modems or complex tools.
But the disadvantages of mobile internet can be poor coverage in some parts of the country, high tariffs, weather conditions, and insufficient support. Mobile internet services are using 4G, 3G, and GPRS technologies. The speed of 4G technology is very fast and constant which allows users to easily upload or download various big files.
The previous generation of mobile internet, 3G technology, has slow in speed than 4G and it takes more time to load. Any device that supports LTE technology, by using a 4G SIM card, you can enjoy high-speed Internet. Some operators also support the new generation 5G, which allows loading up to 300 MB / s.
Uses Of Internet
