The internet is a global network of interconnected computer networks that use standardized protocols to share information. It connects computers around the world like a system of motorways, allowing them to communicate through requests and responses between clients and servers. When a user enters a website address, their request is sent to a domain name server to lookup the IP address and direct the query to the proper web server, which then sends back the requested information in packets to be reassembled by the user's browser.

The internet
The document discusses the basics of how the internet works. It explains that the internet is a global network of interconnected networks that uses standardized communication protocols. It describes how domain names identify websites and are translated to IP addresses, which are numeric identifiers for devices on a network. The document also outlines how data is broken down and sent as packets via packet switching networks, and how routers communicate between networks to direct packet traffic.
How the Internet Works
The document describes how the internet works by explaining that when a user opens a web page, their computer connects through a series of routers to reach the destination server that hosts the requested page, which can be located far away. The request is passed through routers until it reaches the destination server, which then sends the information back to the user's computer through the same network of routers.
Web Terminology
It is a collection of related web pages that may contain text, images, audio and video. It is the data communication protocol used to establish communication between client and server.
Lec 1 intro to internet
The document discusses how the internet works at a high level. It explains that the internet is a network of interconnected computer networks that transmit data via packets. Packets are broken into smaller units at the sender, routed from node to node via routers, and reassembled at the receiver. It also describes how domain names map to IP addresses to make the network accessible, and how the world wide web uses HTML documents, HTTP, and browsers to share hyperlinked information over the internet.
Continuous integration
Cloud computing provides virtual resources that allow users to search and access documents through the internet without needing local storage. Cloud document search allows users to easily find documents by title or full text from any device. Continuous integration extends development principles to help teams deliver code changes more frequently and reliably through a set of cultural practices and techniques implemented as a pipeline.

Computing 9
Computer networks connect devices to share resources and communicate. Connections are usually made with physical cables but can be wireless. Networks transfer data at different rates, with speed being a key issue. The client/server model opened computing to sharing files and web pages across networks. Networks can be local-area networks spanning a small area, wide-area networks spanning large distances, or metropolitan-area networks in cities. Protocols like TCP/IP and HTTP allow communication across networks by breaking messages into packets and reassembling them.

The internet
The Internet connects millions of computers around the world through networks and websites. It allows for quick transmission of information globally. Domain names, like website addresses, point to IP addresses which are numeric identifiers for computers on the network. This is easier for people than remembering long strings of numbers. Data being sent, like emails, are broken into packets which routers help direct to the proper destination and reassemble for viewing. Routers ensure smooth functioning by routing data packets to the correct destination network or computer.
The internet
The Internet is a worldwide network that connects millions of users globally and presents different information and communication facilities. Domain names like URLs provide an easier way to access websites through memorable addresses rather than long strings of numbers. IP addresses uniquely identify devices on the network and are required for communication between computers. However, domain names act as links to the underlying IP addresses. Data is broken into packets and sent through routers on the network, which determine the fastest route using routing tables.

How The Internet Works
- 2. WHAT IS THE INTERNET? • OxfordDictionaries.com gives the definition of the internet as: “noun (the Internet) a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols.” • Think of it like the motorways connecting cities together, without these direct connections it is a lot harder to get information to and from different computers.
- 3. HOW DOES IT WORK? • Your computer (the client) sends a request over your Internet Service Provider (ISP) to a Domain Name Server (DNS). • The DNS looks for your request. If it finds a match it will forward the request to the correct servers Internet Protocol (IP) address. • If it can’t find a match it will send the request to another server with more information. • When that request reaches the correct Web Server, the server will then send the information required back to the client via a series of packets – different parts of a file to be pieced together like a jigsaw puzzle by the clients web browser.
