    The basic operation of a computer is called the ‘fetch-execute’ cycle. The computer fetches the instruction from its memory and then executes it. This is done repeatedly from when the computer is booted up to when it is shut down.

    Fetching the instruction - The CPU fetches this from the main memory (the hard drive) and stores it in the CPU temporary memory

    Executing the instruction - When the instruction has been decoded, the CPU can carry out the action that is needed. This is called executing the instruction

    A client server network is a method of organising a network where you have lots of computer systems (the clients) that access different servers. (for example in schools and universities)

    A peer to peer network is more like a network set up at home, or in a small office with less machines.
    Thanks. how's your revision going?

    It's several factors why I don't like it.
    I find the course extremely boring this year, just the topics in general.

    The course work was extremely stressful and it was a lot of pressure to hand everything in on time. You know I never got any free time to go out for lunch with my friends because I was struggling to hand in my projects in on time.

    My teacher gave our full year a prelim that didn't reflect previous past papers. It was out of 45 marks whereas the exam is out of 90! And only a small % passed the prelim because it wasn't a good paper that wasn't similar to any part papers in the slightest.

    Also my teacher has gave us notes with a lot of gapped knowledge, some of the questions that come in past papers he hasn't taught us them in eneough detail to get full marks in some questions.

    It depends on the question.

    Yeah those calculations are probably my strongest point.

    I haven't really revised well enough, just been doing past papers and have been finding things okay.

    An Array is basically just a list
    A string is numbers and characters which are together

    I usually notice array when there are square brackets, e.g. A shopping list
    ["Milk", "Yoghurt", "Cheese"]

    Well that's how it looked like in Python

    Basically what you want to do is the following:

    Inch*Inch*DPI*Colour Bit Depth
    4*6*600*24
    =345600 (BITS) / 8 (Divide by 8 here)
    =43200 (BYTES) /1024 (Divide by 1024here)
    = 42.1975 KiloBytes
    Leave your answer as Kilobytes unless the question says otherwise. To convert to MegaBytes just divide by 1024 and then to convert to giga just divide by 1024 and so on...

    If they don't give you the DPI then just do:
    Inch*Inch*Colour Bit Depth
    And then do all the other steps
