Study Notes
Microcontrollers and Integrated Circuits
- A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system.
- An integrated circuit (IC) is a set of electronic circuits on one small flat piece (or chip) of semiconductor material, usually silicon, which can perform various functions.
Applications of Microcontrollers
- Microcontrollers are essential for automating tasks in various devices, controlling processes in automotive systems, household appliances, and robotics.
Advantages of Microcontrollers
- The main advantage over computers is their lower power consumption, size, and cost, enabling them to operate in resource-constrained environments.
Embedded Systems
- An embedded system refers to a dedicated computer system designed to perform one or a few tasks, often as part of a larger system.
Radiation Uses
- Some applications of radiation may not be beneficial, such as using radiation in weaponry or harmful medical procedures.
Atom Concept
- The concept of an atom was first proposed by ancient Greek philosopher Democritus, who theorized that matter is composed of indivisible particles.
Focus of Radiation Physics
- Radiation physics primarily studies radiation's properties, interactions with matter, and its applications in fields such as medicine and energy.
Ionizing vs. Non-Ionizing Radiation
- Ionizing radiation has enough energy to remove tightly bound electrons from atoms, leading to ionization; examples include gamma rays and X-rays. Non-ionizing radiation lacks this energy and includes radio waves and microwaves.
Purpose of X-ray Security Scanning
- Security scanning using X-ray technology aims to detect concealed items, such as weapons or explosives, by producing images of the contents of bags or bodies.
