    yeah but it should remain close though right? like it went down by 4 marks in 2015. however, in 2011, the grade boundaries were like 72/80 which is significantly different. something like that shouldn't happen right?
    I think the grade boundaries were only high in 2011 because there were very few candidates entered(most likely from private schools). As the number of candidates for computing is substantially increasing every year, the grade boundaries should stay around 60 for and A*.

    Sure.

    I'll put the answers I can remember and hopefully you can put it to the questions... I can't remember the questions and the order.

    Idea that Character set is characters represented by binary digits (bits) understood by computer

    Idea that unicode can hold more characters due to being 16 bit, whereas ASCII can only represent a maximum of 255 characters in 8 bit binary.

    Lauren's Q) - Ideas about Policies (Eg. Acceptable use), Abuse reports, screening and validation, etc.

    Idea that Dual Core has twice as many cores so can process more instructions and execute them faster leading to better performance.

    PC Spec 6 market) Ideas about better CPU, more instructions executed, more performance... Better HDD, more virtual memory and if it's SSD has better R/w time, so better performance... Better GFX, can process more data from cpu into pixels, etc, better performance... More cache more freq. used data can be held and not wrote over.

    ROM VS RAM... Ram - Volatile and Rom non volatile... AND ... Ram re-writable but Rom is pre-loaded at manurfacture.

    Binary, first one.... 0100 for "4" and 1010 for "A"....

    Sequence for order code ran in....

    Remind me of questions.

    LAN VS WAN:

    WAN over wider area, LAN over short local area.
    WAN slower as has more data collisions and encounters more data but LAN doesn't.

    Supermarker Q)
    Security, although I crossed it out...
    Accessability.

    Database Q)

    Record Example: Age.

    ideas about being in other table as foreign key.

    Correct data types and explination.
    Could you go into more detail on the supermarket question since I forgot what it was?

    ohhh yess. so I guess it should remain close to 60 like 2014 and 2015? I was really scared that it would go as high as 72 or something

    OCR supermarkets has servers and the checkout computers as clients. what are the benefits of using a client-server network as opposed to a peer-to-peer network? 4 marks

    Thanks
    If that was the only client server vs peer-peer network question then I'm pretty sure i did really well
    Thanks!

    Client-server is comparatively more secure than peer-to-peer as users need passwords to access the network.

    1) all the data is stored centrally so if the computers fail, the customers data won't be lost, unlike a peer-to-peer network
    2) the client computers can seamlessly be replaced as the server containing all the data can easily be connected to the new computers so the customers' data isn't made vulnerable

    how many marks out of 4 would that give me?

    Use this to find out what you need using last year's grade boundaries.
