Study Notes

Arduino

An Arduino is a microcontroller, a simplified central processing unit (CPU).
It controls electronic components like lights, motors, and sensors.
To make a light illuminate, you need a power source, a cable, an Arduino board, and a resistor.
Connecting the light to the Arduino entails programming the microcontroller to send power to the light, causing it to illuminate.

Binary System

The binary system uses only the digits 0 and 1.
With one bit, you can represent values from 0 to 1.
Two bits allow representation of values from 0 to 3.
A bit is the smallest unit in the binary system, which can be either 0 or 1.
A byte comprises 8 bits, enabling the representation of 256 different values (0 to 255).

Robotics

Robotics is used in various industries, medicine, and surgeries.
It aids in tasks such as surgeries, patient rehabilitation, plant care, and even space exploration.
Benefits include rapid task completion, task safety, and constant operation without breaks.
Industrial robotics advantages include improved efficiency, enhanced quality control, and increased worker safety.

GPU

GPUs are specialized processors designed for parallel tasks, like graphic rendering and AI computations.
CPUs are better suited for sequential tasks.
GPUs are commonly used in gaming and graphics, artificial intelligence, video and image processing, and cryptocurrency mining.
GPUs also assist in developing and utilizing autonomous systems.

Motherboard

A motherboard connects all essential computer components, enabling communication and power supply.
Crucial components include the CPU (central processing unit), RAM (random access memory), chipset, expansion slots, and storage interfaces such as SATA, M.2, or hard drives.
It also includes input/output ports, such as USB and HDMI, to link peripherals.

Cloud Services

Cloud services encompass various models like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
IaaS provides virtual machines and storage.
PaaS offers development platforms.
SaaS delivers applications like Google Docs and Microsoft 365.

RAM

RAM (Random Access Memory) is volatile memory, meaning data is lost when the computer is turned off.
RAM is used for temporary data required by running programs and processes.
When RAM is full, the computer relies on slower storage like hard drives, impacting performance.

Cryptocurrency

Cryptocurrency employs cryptography to regulate transactions.
Transactions involve transferring digital currency between wallets.
Verification, achieved via mining consensus, validates transactions.
Transactions are recorded on a digital ledger called a blockchain.

Monitor, Speakers, Projector, Camera, Microphone

Projectors use technologies like LCP (Liquid Crystal Panel) or DLP (Digital Light Processing) to display images.
Bright projectors are better for clear images in brighter environments.
Projector resolution is affected by factors like light intensity, with higher resolutions providing sharper images.

Cybersecurity

Firewalls monitor and control data traffic between computers and the internet, blocking unwanted connections.
Packet filtering examines data packets, allowing or blocking them based on rules.
Stateful inspection assesses the entire connection context, ensuring secure communication.
Proxies facilitate and secure access to networks.
