Sub Strand: 1.4 Computer Storage

STRAND 1.0: FOUNDATION OF COMPUTER STUDIES

Sub Strand: 1.4 Computer Storage

Specific Learning Outcomes

By the end of the sub-strand, the learner should be able to:

a) identify the types of storage used in computer systems,

b) categorise the types of storage used in computers,

c) read data from computer storage,

d) write data to computer storage,

e) describe the criteria used to select computer storage,

f) acknowledge the safety of data in computer storage media.

Suggested Learning Experiences

The learner is guided to:

• brainstorm the types of storage devices,
• discuss the categories of computer storage (primary and secondary),
• Use print or digital media to search for the types of primary memory (RAM and ROM),
• discuss the types of RAM technology (dynamic RAM (DRAM) and static RAM (SRAM)),
• differentiate between DRAM and SRAM,
• Watch a video on the features of Read-only memory (ROM) chip technology.
• Discuss the differences between RAM and ROM chips.
• Consult a resource person to discuss and demonstrate how ROM and RAM chips are used.
• scan a document and share with peers,
• visit a computer user environment and identify the input/output devices (traffic cameras, surveillance cameras, speed sensors, weather and sensors, smart traffic lights),
• match input and output devices to their uses,
• sensitise community members on how to reuse input/output devices,
• Watch a video on how traffic and surveillance cameras record and monitor traffic flow.
• discuss methods used to output information from a computer,
• brainstorm factors to be considered when acquiring input and output devices,
• discuss the importance of using input and output devices in different areas (home devices, roads, cars, ATMs, Point of Sale Terminals, businesses, communication, and safety systems),
• Consult a resource person to demonstrate how input and output devices enhance road safety,
• create a quick response (QR) code and share information such as warnings and updates on road safety,
• Discuss the advantages and disadvantages of QR codes and traditional barcodes.

Suggested Key Inquiry Question(s)

1. How is data accessed from computer storage?
2. What informs the choice of computer storage?

Core Competencies to be Developed

Creativity and Imagination: The learner generates new ideas to create a quick response (QR) code and share information.

Learning to Learn: The learner shares experience on how to reuse input and output devices.

Values

Peace: The learner respects self and others while discussing the advantages and disadvantages of QR codes and traditional barcodes.

Unity: The learner collaborates with others to scan and share documents.

Pertinent and Contemporary Issues (PCIs)

Socio-economic and Environmental Issues: The learner observes safety in a computer user environment as they identify input/output devices.
