Internet is the biggest network created nowadays and conect all the computers all over the world. Thanks to this, people can use Internet to communicate or share information to any part of the planet.

The Internet appeared in the world in the 1970s, but before that it had a predecessor: ARPANET, a network created with the idea of ​​interconnecting scientists between universities. One of the key creators of the ARPANET was Vinton Cerf, who is often referred to as "the father of the Internet." Together with Robert Kahn, Cerf developed the Transmission Control Protocol/Internet Protocol (TCP/IP), which allows communication between different networks. Then in 1971, he would send the first email. And at the end of that decade, Apple was already launching the first personal computer.

Internet work thanks to a series of networks that connect all devices of all the world. Basically it transport information around the world and this information us stored on servers.

And information is distributed thanks to a Routers network.

A Server is a program or a device that provides functionality for called clients which are other programs or devices. This architecture is called the client-server model.

A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection. There are thousands of routers spread across the world to help move data around from one place to another.

A single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities called services. These services include sharing data or resources among multiple clients or performing computations for a client. Multiple clients can be served by a single server, and a single client can use multiple servers.

The browser sends an HTTP (Hypertext Transfer Protocol) request message to the server, asking it to send a copy of the website to the client. This message, and all other data sent between the client and the server, is sent across your internet connection using TCP/IP (is a data link protocol used on the Internet for computers and other devices to send and receive data)

DNS (Domain Name System) translates "human language" (www.Youtube.com) to machine readable IP addresses(199.223.232.0)

The URL is a nickname for a website, the IP Address is the real name. Every computer on the internet is assigned a series of numbers, like(199.223.232.0).That series of numbers uniquely identifies the computer that hosts a website. The first step in finding a website is to translate the URL into the equivalent IP Address.

It’s a hardware that includes memory, hard drive, network connectivity, and runs operating systems and applications off its internal hardware resources. A physical server can be designated to a single user or can be used by multiple users.

A virtual server recreates the functionality of a physical server. It exists transparently to users as a partition space within a physical server. Server virtualization makes it easier to reallocate resources and adapt to dynamic workloads.

Routers are commonly connected by cables, which are used to send data across a long distance. That data is usually represented using bits . Cables range from telephone wires to coaxial cable to fiberoptic cable. All of these systems convert bits to different real -world representations (analog signal, electricity, light, etc.). Computers can also send data to routers over Wi -Fi. In this connection, data is sent over a short distance via radio waves.

Mac address (Media Access Control Address) is a unique identifier assigned to a network interface controller to be used as a network address in communications within a network segment.

Internal IP addresses designate which device in a local network is your computer, compared to other devices which might be using the intranet connection.

An external IP address, also known as a public IP address is used across the Internet in locating computer systems and devices.

A web browser is a type of software that allows you to find and view information or websites on the Internet. There are many different web browsers, but some of the most common ones include Google Chrome, Safari, and Mozilla Firefox, etc.

HTML stands for Hyper Text Markup Language, it is the standard markup language for creating Web pages. HTML describes the structure of a Web page, it consists of a series of elements which tell the browser how to display the content. HTML elements label pieces of content such as "this is a heading", "this is a paragraph", "this is a link", etc.

Fault tolerance refers to the ability of a system (computer, network, cloud cluster, etc.) to continue operating without interruption when one or more of its components fail.

The objective of creating a fault-tolerant system is to prevent disruptions arising from a single point of failure, ensuring the high availability and business continuity of mission-critical applications or systems.

Fault-tolerant systems use backup components that automatically take the place of failed components, ensuring no loss of service.

The ISP is the Internet Service Provider. A company that provides Internet access to its users through different technologies such as ADSL, modem, GSM, dial-up, optical fiber , satellite, streaming, etc.
