How Does YouTube work ???

Have you ever wanted to know how YouTube work.  Well your going to find out anyway !!!

 

Here’s a explanation !

 

It’s not all about cute cat videos and funny home movies though, as YouTube has also helped people launch careers. For example, pop star Justin Bieber was first discovered when a talent scout saw videos of him singing on the site, and Zoe Sugg, aka Zoella, has got her own book deal and range of beauty products as a result of her popular video blog, or ‘vlog’. You can even earn money directly from YouTube too, as the site shares some of the revenue it makes from companies who pay to run adverts before or over your video.

Another benefit of YouTube is the ability to embed videos on other websites. By simply copying and pasting a bit of HTML code, you can enable people to watch a video on your own website using the YouTube player. This saves you having to host the video on your site which requires a lot of bandwidth. Bandwidth is the range of signal frequencies needed to transmit data over the internet and you have to pay for the amount you use. YouTube streams vast amounts of data each day, carrying the bandwidth burden for other sites that want to display video.

How does wifi work? (explanation)

Like mobile phones, a WiFi network makes use of radio waves to transmit information across a network. The computer should include a wireless adapter that will translate data sent into a radio signal. This same signal will be transmitted, via an antenna, to a decoder known as the router.Image result for wifiImage result for wifi

How does the internet work?

The internet is millions of computers that are digitally connected to each other by cable, fibre or wireless links. The internet is used everyday by people from around the world. The internet can be used for websites, listening to music, communicating with people or to do so many other things. But have you ever wondered about how the internet works?

If you are on a website and there are pictures. How do the pictures send through to your computer?

Sending and Receiving information:

An images is hosted on a web server, so your computer sends a request to the web server for the image. The computer sends a request for the image automatically.

When the request is sent, it is sent in a ‘packet’. Imagine a packet as a virtual parcel that hold lots of important information. The most important pieces of information are the web server that the images is stored on, and the IP address of you computer.

Special computers (routers) and devices (switches) direct the packet from your computer to the web server. Also, the web server could be local or on the other side of the world.

 

 

how youtube works

 

Since it first launched in 2005, YouTube has quickly become the number one destination for video content online, attracting over one billion regular users. The Google-owned site gained popularity by enabling people to share their videos with others all over the world, whether it’s an amusing clip of their pet, or footage of them dancing in their living room.

It’s not all about cute cat videos and funny home movies though, as YouTube has also helped people launch careers. For example, pop star Justin Bieber was first discovered when a talent scout saw videos of him singing on the site, and Zoe Sugg, aka Zoella, has got her own book deal and range of beauty products as a result of her popular video blog, or ‘vlog’. You can even earn money directly from YouTube too, as the site shares some of the revenue it makes from companies who pay to run adverts before or over your video.

The popularity of YouTube is mainly down to how easy the website is to use. Videos in a range of file formats can be uploaded as YouTube converts it into its Adobe Flash video format, with the file extension .FLV, for you. This enables the video to be played using YouTube’s Flash player, which can be installed on your computer or smart device for free.

Another benefit of YouTube is the ability to embed videos on other websites. By simply copying and pasting a bit of HTML code, you can enable people to watch a video on your own website using the YouTube player. This saves you having to host the video on your site which requires a lot of bandwidth.

How does… Smart Phone Touch screens work?

Definitions of word at the bottom of the post. Look for words hi-lighted in red.
‘Unlike resistive touch screens, capacitive screens do not use the pressure of your finger to create a charge in the flow of electricity. Instead the work with any thing that holds an electrical charge – including human skin.’
Basically, your phone will need your skin to complete the electrical circuit, using your skin will help the phone find where you have touched.

Here are some websites that I have used and will give you extra infomation..

How Does YouTube Work?

Image result for youtube

YouTube is an American video-sharing website headquartered in San Bruno in California. This service was created by three PayPal employees: Chad Hurley, Steve Chen, and Jawed Karim in 2005.

To help connect users to the videos they are looking for, YouTube uses a ‘complex algorithm’ made up of over one million lines of code. When you search for a video, the algorithm decides which search results it will show you and in what order. One of the main factors used to rank the results is video metadata. This is the title, description, thumbnail and tags that you give your video when you upload it, so you should make sure they are relevant to the content of the video and what people might search for to find it.

“Every video uploaded to YouTube is stored in at least one of Google’s 14 data centres spread across the world. These enormous buildings contain thousands of servers – the powerful computers that handle the billions of Google searches made every day and also store your videos. Giant cooling towers keep the temperature inside at a steady 27 degrees Celsius (80 degrees Fahrenheit) to ensure the equipment runs smoothly, and each piece of data is stored on at least two servers for extra security. The data centres can also communicate with each other to send information between them. When you upload your video it will be stored at the data centre nearest you, but when someone wants to play it, the video will be sent to their nearest data centre for quick access. This also means that in the event of a fire or other disaster, the data is sent to another data centre so that it’s always accessible.”

Naajidah’s picture of what the Internet looks like

After our computing lesson this week, I was impressed when Naajidah showed me a picture she had drawn at home. It shows a phone connected by WiFi to an access point and then connected by cables. It also shows that if one of the servers isn’t working then the data can often find another way around.

A very impressive and detailed diagram!
