The question as text

A student has an application (app) on their smartphone that can be used to identify the name of a flower. The student opens the app and takes a photograph of a flower. The photograph is stored as an image. The app searches its database for similar images to find the name of the flower.

  • 6(a)[3]

    Three from:

    Image is broken down/divided into pixels
    Each pixel is a single/one colour
    Each colour/pixel has a binary value

  • 6(b)[4]

    Four from:

    For example:

    It can use machine learning
    … by adapting its own data/rules/processes
    It can use image recognition
    It can analyse/identify the patterns (in different flowers)
    It can use feedback from user/human
    … to identify/store successful/unsuccessful identifications
    It can be trained by being shown pictures of flowers …
    … to learn in more detail/new characteristics of flowers

  • 6(c)(i)[1]

    One from

    The app data won’t take up storage space on their device // There will be more storage space on the device for other files
    They don’t need to download the data each time they get a new device
    The data can be accessed from any device they use // The data is still accessible if their device breaks/is lost

  • 6(c)(ii)[2]

    Two from:

    Need an internet connection to access the data stored in the cloud // If internet is slow/unstable app could be difficult to use
    If the cloud storage is down/broken/fails the app cannot be used/access to data is lost
    Relies on a third party to keep any (personal) data secure/safe/private that is provide to the app // (personal) data stored by the app could be less secure/safe/private
    Access speed to the data may be slower/more limited (than stored locally)
