Study Notes

Brief History of the Internet

The internet started as a networking project in 1958 by the U.S. Department of Defense
The goal of the project was to create a network resistant to disasters and allow scientists to share information and collaborate on military and scientific projects
The network, called ARPANET, used four main computers, one at each of four U.S. universities to connect academic and scientific researchers across the USA starting in 1969
Today, the network called the internet has over 550 million host computers connected
No single entity or government owns the internet

Internet Services

The internet has changed how we communicate through the use of computers and mobile devices
Internet services such as e-mail, instant messaging, chat rooms, VoIP, and FTP allow for various forms of communication
E-mail (electronic mail) is the transmission of messages and files via a computer network and can include text, images, audio, and video
An email address is a combination of a username and domain name separated by the @ symbol
Mailing lists are a group of email names and addresses with a single name. When a message is sent, everyone on the list receives a copy.
Instant Messaging (IM) is a real-time communication that enables users to exchange messages and files and join private chat rooms
IM users must be online at the same time, and the receiver must be willing to accept messages, and all individuals on the contact list must use compatible instant messaging applications

Chat Rooms

A chat room is a location on an internet server that allows users to chat with each other
Chats are real-time typed conversations that take place on a computer
Some chat rooms include voice and video chats
To start a chat session, you connect to the chat server through a chat client
Browsers typically include a chat client, but users can also download one from the web

VoIP (Voice over Internet Protocol)

VoIP (also known as Internet telephony) allows users to speak to other users via the internet instead of the publicly switched network
VoIP requires high-speed internet, internet telephone service, a microphone/telephone, and internet telephone software

FTP (File Transfer Protocol)

FTP is an internet standard that allows files to be uploaded and downloaded with other computers on the internet
Downloading is the process of a computer receiving information from a server on the internet
Uploading is the process of transferring documents from a computer to a server on the internet
Many operating systems have FTP capabilities

Many users connect through high-speed broadband internet service providers, such as cable internet service, DSL, FTTP, fixed wireless, WiFi, and satellite internet service

The World Wide Web: Introduction

The World Wide Web was started in 1989 by Sir Berners-Lee with the goal of exchanging information flawlessly

Each electronic document on the web is a webpage
A website is a collection of related webpages stored on a web server
A web server is a computer that delivers requested webpages to a user's computer
