Ethernet is the technology that builds up the network world and connects different devices. It was invented in 1979 by Bob Metcalfe who physically cabled computers to a printer to share communication and messages. Ethernet allows signals to be transmitted from a sender to receivers and connects people online through various mediums like sending documents to printers or clicking hyperlinks. It has evolved from initial speeds of 10Mbit/s to 10Gbit/s to expand network coverage and offer better online performance for users.

Ethernet
Ethernet is the technology that builds up the network world and connects different devices. It was invented in 1979 by Bob Metcalfe who physically cabled computers and a printer together. Ethernet works by sharing messages between connected mediums using a sender-medium-receiver model. While the internet allows for global online activity, Ethernet is the underlying technology that transmits signals between connected devices, from small local networks to the large global network, and it continues to evolve with higher speeds to improve performance.

When you connect to the Internet, your computer becomes part of a network. The Internet is a global collection of networks that connect together through various infrastructure components like routers, servers, and protocols. It allows information to travel quickly between any two connected computers worldwide, making the complex system seamless to users. The domain name system (DNS) translates easy-to-remember names to computer-readable IP addresses, while protocols like HTTP define how computers communicate over the Internet. No single entity owns the Internet, rather it is a network of networks maintained through cooperation.
Ahaana - How Internet Works
The document provides information about information technology and how the internet works. It discusses:
1. Information technology deals with using computers and software for processing data, information, and knowledge. Computer science focuses more on algorithms and mathematical techniques.
2. The internet is a global network of interconnected computer networks that use TCP/IP to connect billions of users worldwide. It allows information to be shared through communication protocols like HTTP and email.
3. Websites are made up of web pages that can contain text, images, videos and more. Web pages use HTML and are accessed via URLs on the internet through browsers.
Introduction to internet
The document provides an introduction to the Internet, describing its origins from ARPANET and how it functions as a network of interconnected computer networks that allows users to access data remotely. It discusses that the Internet relies on protocols like TCP/IP to allow different systems to communicate and that no single organization owns or governs the Internet, with responsibilities divided among groups that set standards, discuss technical issues, and provide registration services. It also outlines some basic requirements to connect to the Internet like a modem, ISP, and special programs to control communication of data over hardware components.

Ch01.pdf kurose and ross
The document provides an overview of computer networking and the Internet. It describes the Internet as a worldwide computer network that interconnects millions of computing devices, allowing distributed applications running on end systems to exchange data. The Internet consists of end systems connected by communication links and routers. End systems access the Internet through internet service providers. Key protocols like TCP and IP control the sending and receiving of information and allow this global communication infrastructure.
Using Interconnected Computer Networks For Communication
The document discusses the protocol stack, specifically how data moves through the layers of the TCP/IP and OSI models when requesting a webpage from a web server over a WAN. It explains the encapsulation process at each layer, such as how the application layer protocols HTTP and DNS are used, and how at the transport layer data is segmented and port numbers are added. It then discusses how at the network layer, logical addressing is applied to packets before being forwarded across the WAN. The document also covers subnetting IP addresses and includes screenshots of routing/switching device outputs and an email example.
Internet and telecommunications
The document discusses the history and development of the Internet and telecommunications. It describes how the Internet was created to allow computers to share information over long distances. Key pioneers who contributed to the development of the Internet and digital communication technologies are profiled, including Vannevar Bush, Claude Shannon, and Tim Berners-Lee. The document also outlines common uses of the Internet today, such as e-commerce, communication, media/entertainment, and how information travels across the global network of connected devices.
Computer communication
This document provides an overview of computer communication networks. It discusses the history of computer networking from the 1960s development of modems to connect computers over telephone lines. This allowed for the rapid expansion of local and wide area networks in the 1970s and 1980s. The document also describes different types of computer communication including email, chat, video chat, and VoIP phones. It defines key concepts like packets, packet headers, and routing in computer networks.

Ethernet_Koston
- 2. We live in Network and are being fond of it.
- 3. An Ethernet is the entrance to Network World. Once you put a RJ45 plug connector into your device . I glad to tell you that...
- 4. “Welcome, you are connected with Network”
- 5. Thanks to Network,our life become more convenient. And now, we communicate with Network every single day Whether we only check an email, Facebook, or writing a NIKI entry which is the moment we are in Network. It makes us so powerful to do everything immediately. I can tell we kind of rely on this world and we love it.
- 6. However, what kind of thing build up this world? Internet? My Answer is Ethernet. People often think Internet produce our Network. However, Internet just refers all human online activities. Ethernet is the technology build up this Network world step by step.
- 8. Before I proceeding it, let’s see how it comes? Ethernet employs the theory of communication practise. In 1979, the employer of Xerox Corporation Bob Metcalfe invented the initial Ethernet by physically cabling the communication from his computers to a printer. In other words, Ethernet is a station to assemble different mediums into one space where the mediums are connected. Technically, the messages are shared between the mediums, and runs with the mode of Senfer-Meidum-Receivers (SMR).
- 10. 40 years ago, neither the speed of Internet nor the extent of Internet is as advanced as modern time. Ethernet as a necessary medium transmitting signal from sender medium to receivers medium. 40 years after, we still do the same thing. From you sending a Word document to a printer in a small Ethernet to you clicking on a hypertext in a large Ethernet, every step you’ve done is Ethernet communication. Ethernet is evolving along with the industrial revolution…
- 11. From the initial 10Mbit/s to 10Gbit/s, Ethernet is not only expanding the coverage of Network, But also offering a better and better online performance to users.
- 12. Now we can communicate with the world immediately!
