    Exam objectives

    • Define data and information and distinguish clearly between them, with an example
    • List the stages of the data life cycle: creation, management, removal of obsolete data
    • State the characteristics of valuable information (timely, accurate, in context, understandable, low uncertainty)

    Important areas to cover

    • "Distinguish data from information" is a near-annual short-answer opener
    • Listing the characteristics of quality/valuable information is a common structured question

    Notes

    Data is raw, unprocessed facts with no meaning attached yet — a number, a word, a single reading. Information is data that has been processed and given context, so it becomes useful for making a decision.

    25, 30, 28, 32 are just data on their own — four numbers with no story. Plot them against the days of the week and average them, and you get "this week's temperature has been rising" — that is information.

    • Data is the raw material: one exam score
    • Information is the finished product: a class average, a rank, a trend

    The data life cycle

    Every piece of data moves through three stages before it disappears again:

    • Creation — data is generated: a sensor reading, a form submission, a bank transaction
    • Management — data is stored, organised, backed up, and processed into information
    • Removal of obsolete data — data no longer accurate, needed, or legally required to keep is deleted or archived

    Skipping that third stage is not free. A system that never deletes old records slows every search down, and can breach data-protection law the moment it keeps something it no longer has a reason to hold.

    What makes information valuable

    Information is only worth acting on if it is:

    • Timely — it arrives while it can still be used
    • Accurate — free from errors introduced while collecting or processing it
    • In context — meaningful for the situation it is used in
    • Understandable — presented so the reader can actually interpret it
    • Low in uncertainty — trustworthy enough to base a decision on

    Exam angle: a scenario question usually tests exactly one of these five properties at a time. Read for which one is missing, and answer that — don't list all five unless the question actually asks for them.

    Try it — follow one record through the life cycle

    Data is generated the instant an event happens — typed in, sensed, scanned or submitted.

    A student taps "Submit" on a mock exam. That instant, a new record is created: their answers, the time taken, the raw score.

    Exam objectives

    • Explain the drawbacks of manual data processing (errors, duplication, delay, poor sharing)
    • Describe how networks, the Internet, mobile computing and cloud computing overcame those drawbacks
    • Give examples of information used in decision making, policy making, prediction, planning and monitoring

    Important areas to cover

    • "Why did ICT replace manual methods" recurs as an essay-length Part A prompt
    • The network → Internet → mobile → cloud timeline is a common short-essay question

    Exam objectives

    • Draw and label the input-process-output (IPO) abstract model
    • Relate the IPO model to a computer system and to the general definition of a system

    Important areas to cover

    • Low period weight — expect a quick diagram or definition question, rarely essay-length

  4. Join this class

    Exam objectives

    • Classify the hardware and software components of a computer system
    • Distinguish proprietary from open-source software, with an advantage and disadvantage of each

    Important areas to cover

    • Proprietary vs open-source comparison is a frequent short-structured question

  5. Join this class

    Exam objectives

    • List and describe the five data-processing steps: gathering, validation, processing, output, storage
    • Identify data-gathering tools (OMR, OCR, MICR, card/tape readers, barcode readers, sensors) and validation methods (type/presence/range checks)
    • Distinguish batch vs real-time processing, online vs offline input, and local vs cloud storage

    Important areas to cover

    • Matching a named tool (OMR/OCR/MICR/barcode) to its purpose is a common MCQ pattern
    • Batch vs real-time and online vs offline are a recurring paired short-answer question

  6. Join this class

    Exam objectives

    • Identify the ICT tools and skills used in education, healthcare, agriculture, business, engineering, tourism, media and law enforcement
    • Discuss, in depth, the benefit ICT brings to at least two named domains

    Important areas to cover

    • "Discuss the use of ICT in domain X" is a recurring Paper II Part A prompt — prepare 2-3 domains in real depth

    Lesson content not added yet.

  7. Join this class

    Exam objectives

    • Explain the social and economic benefits of ICT
    • Explain the social, economic, environmental, ethical, legal and privacy issues caused by ICT — piracy, phishing, copyright, plagiarism, licensing, digital divide, e-waste
    • Relate ICT's role to the Sustainable Development Goals and to closing the digital divide

    Important areas to cover

    • Ethical/legal/social issues (piracy, copyright, licensing) is a near-guaranteed structured question
    • e-waste disposal and digital divide are common short-answer add-ons to the main question
