How The Internet Works
--------------------------------------------------
Hi lovely people! My name is Mia & welcome to my page. I am currently learning about computers and how they work in my computer science class. One of the interesting things that I have been learning about is creating a websit me using codes on Neocities. We've learnt how to create a title, some heading texts (as seen above) and now I am writing a paragraph about me, introduction, and what I've enjoyed so far in my journey of computer science. I will be writing about the basic things, or words that I have learnt about in Computer Science. So if you have any struggles, feel free to scroll down to find any information which you need. See you soon!

A user is a person who has accessed the internet in the last year (or 12 months) from any sort of device. This includes mobile phones too. There are around 3,634,975,000 of internet users around the world. This increases by about 6 users per second! Did you also know that China has the highest number of internet users, with 731,434,547 number of people. This is only a fraction compared to the global internet users, as recorded on January on 2017, with 3.773 billion internet users around the world. China represents 22% of the total, and has more users than the United States, Japan and India! This contrasts with (Eastern) Africa with only 19% of internet penetration, and has the highest yearly growth rate.

Web Browser...
also commonly said 'browser', is a software application which is used for accessing (displaying and viewing) information on the web, or is hosted by web servers in private networks.

Each link contains a URL, Uniform Resource Provider, of an informaion page to go to. Once the link is clicked, the browser finds the resource which is shown by the link's target Uniform Resource Identifier (URI).

An ISP provides us with internet services, which includes our personal and business access to the internet. Not only does an ISP lets us individual access the internet, ISP also provides internet access to big companies, allowing access directly from the company's network, to the internet. Internet Service Providers are conneted through NAPs, also known as Network Access Points. ISP can also be called IAP, Internet Access Providers.

Webpage...

It is generally written in and identified by their HTML, also known as HyperText Markup Language. A webpage is a document on the World Wide Web, WWW.

Webserver
Webservers are computers which has webpages. All webpages has an IP address and some of them have a domain name. An example would be when you enter a URL, this would send a request to a webserver. Then, the webserver brings the page back and sends it to your browser. Any computer can be turned into a webserver by installing a server software and connecting to the internet.
Fiber Optic Cables
Fiber Optic Cables are specially designed for long distance, data networking, and telecommunication. This is a technology which uses glass or plastic fibers to send data. Each of these fibers, which are slightly thicker than astrand of hair, are capable of sending information which is modulated into light waves. This signal, the pulses of light, are generated by LEDs (Light Emitting Diodes) or small lasers. A strand of each fiber has a core, the center of the fiber, is a pathway for light to travel. The core is covered by cladding, which is a glass. This allows the light to bend inwards, to avoid loss of signals and let light pass through the bends of the cables.
