Q & A

What is the main purpose of learning about computer systems in the provided script?

The main purpose is to enable learners to use knowledge, skills, and understanding of concepts, software programming, and to produce a prototype that can interact with a single board computer or a controller.

How does the script describe the working of traffic lights with different timing at each intersection?

The script suggests that there is a device that commands the traffic lights to switch on and off at different times, but it does not detail the exact mechanism or technology used for this timing control.

What is a Single Board Computer (SBC) and what are its basic components?

A Single Board Computer (SBC) is a computer built on a single circuit board with a microprocessor, memory, input/output slots (often referred to as I/O), and other features needed to function as a computer.

Why are SBCs generally preferred over personal computers for certain applications?

SBCs are preferred due to their general availability of I/O ports, low power consumption (usually under 5 watts), and cost-effectiveness, making them suitable for battery-powered applications.

How does the script differentiate between a SBC and a smartphone?

The script points out that SBCs and smartphones are not the same, highlighting differences in components and use cases, and suggests referring to a table that compares PCs, control boards, and SBCs.

What is the role of General Purpose Input Output (GPIO) in SBCs?

GPIO pins are configurable and can be modified by programmers for specific purposes, providing a versatile means of interacting with various hardware components.

What are some examples of I/O ports that might be found on an SBC like Raspberry Pi?

Examples of I/O ports on an SBC like Raspberry Pi include Ethernet, USB, and HDMI ports.

What is a Single Board Controller (SBCI) and how does it differ from a Single Board Computer?

A Single Board Controller (SBCI) is a microcontroller-based system on a printed circuit board, which is simpler and more focused on controlling external devices compared to a SBC, which functions as a complete computer system.

Why are Single Board Controllers considered cost-effective for application development?
