    How to convert between denary, binary and hexadecimal.
    Uses of each data type.
    Understand different file formats.
    Understand how music, video, pictures and text are stored with data.
    Understand lossy and lossless compression format.
    Error checks(arq, checksum, even and odd parity, automatic repeat request
    1.2 15:03 :
    Transmission types(serial, parallel).
    Understand their uses.
    Simplex, half duplex, and full duplex, plus their individual uses.
    Security software.
    Different types of malware and how they work.
    Understand antiviruses.
    Internet and connection to a pc.
    More stuffs :
    Html apparently(this likely will not be present in the exam paper).
    Logic gates(valuable marks for these questions)
    Input devices.
    Output devices.
    Sensors(last three of pretty handy for small but easy marks).
    Things not mentioned but will be super handy to brush up on :
    Ethics.
    Von neumann architecture.
    Buses and (forgot the name).(someone help me with the last one).
    Different storages(e.g, solid state, ram, all that stuff)

    Good luck!

    3:18 I'm not sure if I made some hidden mistake, but at this time, you said 64 + 8 + 2, which is actually equal to 74, just in case this could be confusing for some
    Edit: someone else pointed it out already, and it was just a mistake, wishing the bestest of luck to all going to the exam tomorrow

    I have some confusion about the logic gate statement you explained at 29:24. You said that we do A NAND B, then we do B NOR C, and then we take the NOT of BOTH of them. But the way I understood, is that we're ONLY supposed to take the NOT of A NAND B, because it's just outside the bracket of A NAND B. Am I right?

    Wait sorry I’m so confused isn’t D (hexadecimal) 13 in denary? I may be wrong but I was just confused because google also says its 13

      Cambridge do not allow their material to be shown on screen and so I no longer do Paper 2 solutions as it would mean having to do it without reference to the actual pre-release task
