What is the Gurdwara
The Gurdwara is the Sikh’s place of worship.
On Wednesday 8th February years 5/6 visited the Gurdwara. When we got there, we had to take our shoes off, wash our hands and the girls had to put a head scarf on. The boys had to put a hat on (the Sikhs call them a turbane). Next a lady took us upstairs to the main room where she showed us where the Sikhs would pray. It was very pretty😏. In the main room they keep the Guru Granth Sahib (their holy book). After that, the lady took us to a different room where she taught us more about her religion with a power point that she created. Later that day, many other people fed us langar, which was basically rice, lentil soup and chapati. Everybody enjoyed it very much! After we ate, they gave us ice lollies and sweets!
To the people who were there, I’d like to say……
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.”

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!
