Study Notes

Introduction to Informática

Informática is the science and application of information, specifically in computer systems and technologies.
It encompasses the design, development, implementation, and maintenance of computer hardware and software.
The field is highly interdisciplinary, drawing on principles from mathematics, engineering, and linguistics, among others.
It focuses on processing, storing, retrieving, and transmitting information.
The goal is to solve problems and achieve desired outcomes using computational tools.

Key Concepts in Informática

Hardware: The physical components of a computer system, like the CPU, RAM, storage devices (hard drives, SSDs), and peripherals (printers, scanners).
Software: The set of instructions that tells the computer what to do. Includes operating systems, applications, and programming languages.
Data: Raw facts, figures, or symbols that are processed by software. Data is typically stored and organized within computer systems.
Information: Processed and structured data that has meaning and context. Information is derived from data and used to make decisions.
Algorithms: Step-by-step procedures for solving problems or performing tasks. Algorithms are fundamental to computer programming and calculations.

Computer Architecture

Central Processing Unit (CPU): The "brain" of the computer, performing calculations and instructions.
Memory (RAM): Short-term storage for data actively used by the CPU.
Storage Devices: Long-term storage of data, such as hard drives and solid-state drives (SSDs).
Input/Output (I/O) Devices: Allow communication between the computer and the outside world (e.g., keyboard, mouse, monitor).
Bus System: Provides communication pathways for data transfer between different components.

Software Development

Programming Languages: Tools for writing instructions that computers can understand (e.g., Python, Java, C++).
Operating Systems (OS): Software that manages and controls hardware resources (e.g., Windows, macOS, Linux).
Application Software: Programs designed to perform specific tasks (e.g., word processors, web browsers).
Software Development Lifecycle (SDLC): A structured process for creating software, including stages like planning, design, implementation, testing, and deployment.
Debugging: Identifying and fixing errors in software. Debugging is an essential part of the software development process.

Computer Networks

Networking: Connecting computers and devices together to share resources and data.
Internet: A global network of interconnected networks utilizing protocols like TCP/IP to facilitate communication and data transmission.
Protocols: Sets of rules governing communication between devices on a network.
Network Security: Measures taken to protect computer systems and networks from unauthorized access and attacks.

Data Management and Analysis

Databases: Structured collections of data typically managed by specialized software systems.
Data Structures: Methods for organizing data in a computer system to optimize storage, retrieval, and manipulation.
Data Analysis: The process of examining and interpreting data to identify patterns, trends, and insights.
Data Visualization: The use of charts, graphs, and other visual tools to represent and communicate data and its insights.

Emerging Trends in Informática

Artificial Intelligence (AI): Enabling computers to mimic human intelligence tasks like learning and decision-making.
Machine Learning (ML): A subset of AI allowing software to learn from data without explicit programming.
Big Data: The analysis of vast amounts of data to identify patterns and trends.
Cloud Computing: Providing computing resources and data storage over the Internet.
Cybersecurity: Protecting computer systems and networks from cyberattacks and threats.
