Study Notes

Cyberbullying

Cyberbullying involves sending hurtful messages or sharing personal information online without consent.
Victims may experience stress and harm from cyberbullying.
In the UAE, cyberbullying is illegal.

Cyber Crime Laws in the UAE

Individuals found guilty of cyberbullying in the UAE may face fines up to 500,000 AED or imprisonment.
These laws aim to promote online safety for technology users.

Embedded Systems

Embedded systems are computer systems with hardware and software that control or monitor a specific task within a larger system.
They are commonly found in devices like air conditioners, digital watches, microwave ovens, hybrid vehicles, and aircraft.
These systems process input and produce output to control system features or actions with varying levels of complexity and user interface.

Microcontrollers

Microcontrollers are tiny programmable computers.
They are often embedded in devices to control them.
Nearly all microprocessors are used for embedded systems.

Data Signaling

Microcontrollers communicate with other devices via electronic data signals using two methods: analogue and digital signalling.
Digital signals use binary digits (bits) to represent information.
Each bit can be interpreted as OFF/0/FALSE/0 volts or ON/1/TRUE/5 volts.
Analogue signals convey more information than digital signals and can use a wider range of values.

Troubleshooting Embedded Systems

Troubleshooting is the process of solving problems in computer systems.
Embedded systems can experience various issues that impede proper operation.
Using effective troubleshooting strategies is essential to resolve issues.
