Q & A

What is the main focus of Module 1.1 for grade 11 ICT?

Module 1.1 focuses on the role and value of ICT (Information Communications Technology) within the workplace, including how it helps to work faster, more efficiently, and make more informed decisions.

What is the significance of the Information Age in the context of ICT?

The Information Age refers to the era where there is an abundance of information available. It emphasizes the need for skills to seek out and sift through this information to find what is relevant, which is a key skill taught in ICT courses.

Why is ICT considered the most valuable subject by the speaker?

ICT is considered the most valuable subject because the skills learned in ICT, such as using computers and digital tools, are essential for a wide range of careers and are skills that last a lifetime.

What is the role of ICT in various careers according to the video?

ICT plays a role in almost every career, including accountants, photographers, engineers, fashion designers, game designers, and web designers, making it a ubiquitous and essential skill in the digital age.

Can you explain the Information Processing Cycle as mentioned in the script?

The Information Processing Cycle involves four stages: input, where instructions or data are given to the computer; processing, where the CPU and RAM handle the data; output, where results are displayed; and storage, where data is saved to a hard drive or similar medium.

What are the three classifications of computers as discussed in the video?

Computers are classified based on purpose, power, and size. Purpose refers to whether the computer is dedicated to a specific task or is a general-purpose device. Power indicates the processing capabilities, and size is a physical attribute.

What is the difference between a netbook, an ultrabook, and a laptop as highlighted in the video?

Netbooks are smaller and cheaper with limited features, ultrabooks are more expensive and powerful with more features, and laptops offer a balance between portability and functionality, with a full-size keyboard and more processing power than netbooks and ultrabooks.

Why are UPS systems important for ICT users?

Uninterruptible Power Supply (UPS) systems are important for ICT users because they provide a temporary source of power in the event of a power failure, allowing users to save their work and shut down their computers properly.

What are some advantages and disadvantages of using digital cameras as an input device?

Advantages of digital cameras include the ability to take a large number of pictures, view, and edit them easily. Disadvantages include the risk of losing the device or data, accidental deletion of photos, and potential loss of memory cards.

What is biometric input and what are its advantages and disadvantages?

Biometric input involves measuring unique biological features of a person, such as fingerprints, for security purposes. Advantages include high security levels, while disadvantages include high implementation and maintenance costs.

How do point-of-sale (POS) systems benefit businesses?

POS systems benefit businesses by providing faster processing of transactions and better stock control, which can improve efficiency and customer service.
