    These are rough approximations of the questions, not word for word
    Question 1: Sat nav I/O
    What is a computer system?
    -A system containing electronic devices that have software and hardware working together
    -It is an electronic data processing machine that can take inputs and output results
    Why does a computer system need input devices?
    -To have data to process
    Give an example of an input device for the sat nav for a disabled person and explain how it is useful.
    -Keyboard. Only sensible one so far.
    Why does the satnav need a secondary storage device?
    -store maps, previous locations etc.
    Why solid state storage?
    -Portable-small, light
    -withstand movement, no moving parts
    Why are the commands stored as binary?
    -1 and 0 can easily be represented via on and off siganls. It allows easy simple logic gates. It allows less error as there are only two values
    Name a task carried out by the CPU:
    -To fetch/execute commands from memory
    -To decode commands
    -To carry out the fetch, decode, execute cycle
    -Perform Logic operations

    Question 2: HTML and internet
    What else might be in an HTML file other than text for the webpage?
    -image references
    -cascading style sheets, CSS
    -video references
    One reason why is it good for HTML to be a standard?
    -All webpages are the same (pretty much) so browsers only have to support html
    -People can have gaurenteed support for their webpage
    -Other languages can be implemented effectively such as php, javascript and xml
    Hex
    - 58 = 3A, 156 = 9C
    Another question ??

    How does the DNS connect the user to a webpage from the URL?
    The DNS has access to a database and associates the URL with a specific IP address. This can access the files and connect the user to the IP which also allows the DNS to contact the correct website.

    3: Algorithm (I think)
    Fill in the gaps
    -'count' and 'Total / Quantity)
    What is a constant and give an example?
    -A value stored in a specific memory location represented by a name. The value cannot be changed while the program is running
    E.g. Quantity
    What data type is the Mean?
    Real as it could be a decimal.
    What other two types of iteration are there other than For?
    -while
    -repeat/do until ?
    It gives an example of a validation algorithm, Give an example of a boundary value and an invalid value.
    -100 or 0 are boundaries
    -anything not between 0 and 100 inclusive are invalid values

    4: Databases
    Why is a database a persistent organised store of data?
    -It is a structured object that contains data. It is stored in tables. (Not sure about this one)
    What is a suitable data type for the ID?
    Text, as it has leading zeros
    How many records are there
    -four
    Which field is the primary key?
    -The first field, it is unique and follows the same format. It is a short number.
    Name a validation method for TeacherID and Date, they must be different.
    -TeacherID, follow format Letter,Letter,ID, or must be length three etc
    -Date, follow format DD/MM/YYYY or it must be less than or equal to the current date
    Name two features of a DBMS that allow you to make customizable applications.
    -Query, ask for records with certain attributes easily, e.g this lets the admin create a query for all outstanding repairs
    -Form, create a GUI to make it easier to make a query, e.g. admin enters teachers ID into search box to get their repairs.

    Question 5: Cars
    Describe the ethical and legal issues surrounding the development of automatic technology such as driverless cars.
    -Cars follow the law always and may not cope in an emergency situation and therefore ccause harm.
    -Cars and automatic devices collect data perhaps unethically or illegally
    -Automation increases unemployment, not right for robots to 'take over'
    -Security required and so could break the data protection Act
    -Hackability, could break the computers misuse act
    Question 6: OCR accounts
    Two advantages of a network in the office over standalone PCs:
    -Share expensive peripherals. All users can use the peripherals plugged in to any PC. This saves money as only one peripheral is needed and all the computers have access saving time.
    -Share data/resources/programs. This allows quicker sharing of data and ideas over methods such as email. It is cheaper as users do not have to use physical storage devices to transfer data. Saves time as users do not have to take so long copying files as they are in a shared folder.
    Name a piece of hardware to get an internet connection. Usually OCR accepts:
    Router, modem (modulator-demodulator) or ADSL adapter
    Name two other pieces of hardware for a network and explain:
    -Router/modem/ADSL, internet connection
    -Hub, connect the devices for sharing
    -NIC, allows connection via Ethernet or wireless
    -Server, dedicated machine to supply data to clients etc.
    -switches, like a hub but faster
    Network policies:
    -Acceptable Use: User priviliges, malware protection etc
    -Backup
    -Failover
    -Disaster Recovery
    -Archive

    Pseudocode:
    the criteria were
    Use iteration
    Have a previously stored number to guess
    allow ten guesses
    say to guess higher or lower
    ask the user to guess
    say congratulations and end the game if they guess it

    I guess that it is one mark per criteria

    approximately
    Const Value = random number
    count = 0
    Ouput 'Guess the number'
    Repeat
    Output 'enter a number'
    Guess = Input
    If Guess = Value Then
    Output 'Congratulations'
    END
    If Guess > Value THEN
    Output 'guess higher'
    if guess < Value then
    Output 'Guess lower'
    count = count + 1
    Repeat until count = 10
    output 'Sorry you did not guess the number. It was' + value
    END

    Why solid state storage?
    -Portable-small, light
    -withstand movement, no moving parts
    There was another question in question 1..

    Question 2
    Question 3:
    Question 4
    Question 5: Driverless cars etc
    question 6: OCR accounts

    Pseudocode:
    approximately
    Const Value = random number
    count = 0
    Ouput 'Guess the number'
    Repeat
    Output 'enter a number'
    Guess = Input
    If Guess = Value Then
    Output 'Congratulations'
    END
    If Guess > Value THEN
    Output 'guess higher'
    if guess < Value then
    Output 'Guess lower'
    count = count + 1
    Repeat until count = 10
    output 'Sorry you did not guess the number. It was' + value
    END

    q 2,3,4
    one of them was databases with an IT maintenance
    Another was algorithms
    another was ???

    Here is a selection of questions with answers:
    Hex question, 3A and 9C
    URL: The DNS has access to a database and associates the URL with a specific IP address. This can access the files and connect the user to the IP which also allows the DNS to contact the correct website.
    constant: a value stored in a specific memory location represented by a name. The value cannot be changed while the program is running

    well one 6 marker was what policies should the OCR accountants implement?
    any idea?
    i wrote data protection act and copyright acts but these are not network policies. i know.
    another 6 marker was about features of DBMS i believe.
    for that i wrote about security and multiple users working at the same time

    what do you think? does that make any sense at all

    why do computers use binary for data and instruction?

    idk what the answer is
    they can only understand and process low level languages, and they have high tolerance (a bit can only be a 1 or a 0, whereas stuff like hex can be 1, 2, 3, A, B, C and so on so there's less chance of errors with binary)

    In terms of policies you're looking at:
    Acceptable Use
    Backup
    Failover
    Disaster Recovery
    Archive

    And in the features of a DBMS I explained a form and a query (wait was this the one where you had to name a feature, explain it and give an example?)

    these were the criteria it had to meet
    Use iteration
    Store number for the user to guess
    say congratulations if the user guessed it
    ask the user to guess the number
    give 10 guesses
    Say whether to guess higher or lower

    By the looks of your pseudocode you will get at least 4 marks. You don't do python be any chance do you?

    What did you guys put for the SatNav question?
    I found it difficult as we only learned about functions to help people with poor sight or limited mobility, but they would not be driving...

    I put touchscreen so deaf people could enter destinations manually rather than via voice command??

    I put braille keyboard as it would mean blind PASSENGERS could use it - drivers can't always operate the system, especially under new crackdown on mobile phones which are where many people have their sat nav

    I put braille as well, but im doubting whether braille is worthy of any marks, after all, how could blind people drive?
