Internet Technology

What is the world wide web?
The world wide web is a set of interconnected networks. It contains millions of files and webpages to be accessed and they are all linked to each other through hyperlinks. To access the WWW you will need a browser. This will take you to the website you need.

Write a brief history of the Internet. You may provide a timeline of important dates where certain elements of the technology were revolutionised.
1962: J.C.R Licklider suggested using computers connected to each other to create a new communications network. This network was called ARPAnet. 1983: Domain name system creates the popular top-level domains. Ex - .com, .gov, .org, etc 1993: The total number of websites reach 600, the USAs White House and the United Nations go online. More than 2 million computers have become connected online. 1998: Google search engine is born. 2004: Facebook launches, The era of social networking begins. 2016: Google unveils Google Assistant, a voice activated AI assistant. 2017: Today the use of the internet is used by nearly every interactable device. This includes phones, computers, consoles, cars and even hospital equipment.

How does the Internet function? It would be a good idea to give an overview of how connections are made.
A client makes a request from their device. This can be visiting a website to streaming videos. The request is sent in a packet, this packet stores the data of said request. The packet is received by the router and directed to the web server. The packet can travel by satellites or by fibre optic cables. The web server opens and reads the packet. The web server then sends the data out in packets, files like images and videos are larger files and can have over 1000 packets. These packets also store information on how to reassemble themselves. When all the packets are received the packets are assembled in the order it tells it to and displays on the clients program, whether that is a game or a website.

Web architecture - For the following list describe what they are and how they help with connecting to the internet.
Internet Service Providers: An ISP is an organisation that gives an internet connection. In web architecture the ISP provides the internet connection for the websites to be available online, as well as giving the capability for devices to connect to the WiFi. Web hosting services: Web hosting services are a type of internet hosting in which allows a person or organisation to make their website accessible online. Domain names: The domain name is the replacement for the IP address of the website. When the user types the domain name (e.g. www.google.com) the letters get converted into numbers and redirects them to the page they wanted to. Domain structures: A domain name structure is a system in which, like a house address, identifies your website's location.

Outline the hardware and software required for the internet. To complete this task you are required to address the following:
Mail and proxy servers: Mail servers, or email server, store your emails using SMTP (simple mail transfer protocol). The messages are sent using an ip address from one SMTP server to another. Routers and Modems: A router is a small device that allows an internet connection in a certain radius. The router forwards data packets along networks. Most home routers use a wireless or wired IP (internet protocol), this joins the home’s Local area network to the wide area network. Browsers: Browsers are a software in which reads HTML and CSS to allow you to view websites from a web server. E.g. Chrome, Internet Explorer, Safari and Mozilla Firefox. Email clients: Email clients are programs that display emails received from email servers. It is used to read and manage emails.

What is meant by User side and Server side?
User Side: These are the devices in which receive the websites data and view the websites. The devices range from desktop pcs to consoles. Server Side: The server holds the websites and all their pages on the hard drive. The device also sends the packets of data towards the internet for devices to use them.

Discuss the factors that influence website performance. It will be a good idea to discuss, user side and server side factors.
User Side Factors Ram: The more ram you have the faster the temporary space for the website is made. Therefore increasing the performance of the website. Browser: Different browsers perform differently depending on the website it is visiting. Some browsers perform better than others. Google Chrome being the predominant one. Processor: A slow processor affects the time it takes to load and display the webpage because the computer needs to process the data. Internet Speeds: Internet speeds affect how long the webpage takes to be delivered to the client. Server Side Factors File types: Using different file types will affect the speed in which the website is received, some file types are larger than others so compressed file types are usually used. Web Server capacity/Bandwidth: The amount of users that can connect to server affects downloads speed as ore bandwidth is being used and more data is being sent out to multiple users.
