Internet and components

Origin of internet:

• ARPANET was created in 1969 and provided the foundation for what came to be known as the Internet. The term Internet became widely used to describe the concept of a worldwide network or connected networks in 1982. E-mail systems date back to the mid-1960s and predate ARPANET and the Internet.
• January 1, 1983 is considered the official birthday of the Internet. Prior to this, the various computer networks did not have a standard way to communicate with each other. A new communications protocol was established called Transfer Control Protocol/Internetwork Protocol (TCP/IP).

Uses of internet:

In general, the internet can be used to communicate across large or small distances, share information from any place in the world, and access information or answers to almost any question in moments.

Types of internet:

• Dial Up Connection.
• Broadband-Connection.
• DSL.
• Cable.
• Satellite Connection.
• Wireless Connection.
• Cellular.
• ISDN.

Internets fundamental rings:

There are three basic internet architecture communication rings. The first, or sending layer, addresses and sends data to the third or receiving layer. The data passes through second or middle layer, often referred to as the cloud.

The sending and receiving layers maybe inhabited by massive commercial or government computing systems, or simply individual users with computer or other internet connected devices such as game consoles or sufficiently smartphones.

Data transmission process:

Data transmission is the transfer of data from one digital device to another. This transfer occurs via point-to-point data streams or channels. These channels may previously have been in the form of copper wires but are now much more likely to be part of a wireless network.

What is Multicasting:

Multicasting refers to a method in computer networking where a single source sends data to multiple recipients on a network simultaneously. It uses a specific Class D IP addressing scheme and is designed to reduce network traffic by delivering a single video stream to multiple receivers efficiently.

What is Unicasting:

Unicast refers to a method of delivering data packets in a point-to-point manner, where each packet is addressed solely to a single recipient. This method is commonly used in LAN and Internet traffic, such as when surfing the web or streaming digital video.

Internet’s future:

Augmented and virtual reality will make browsing the internet a completely different experience. We will interact with technology through voice commands, gestures, or even thoughts. Websites will prioritize hyper-personalization, customizing content and layouts for each visitor.

Future Internet should configure and reconfigure its network services dynamically to satisfy demanders and Internet application can adapt to the change of different network environments. Internet nodes also should be secure and can survive failures and attacks.

Websites:

• Educational sites
• Entertainment sites
• Information sites
• Social networking sites
• Business sites
