Study Notes

L1 Terminology (Software)

Computers have two main components: hardware and software
Hardware is the physical part of a computer, like the monitor, keyboard; think of it as a human body
Software is the set of computer programs instructing the hardware, think of it as the human brain
Software includes code, algorithms, and data structures needed to operate a computer system

Definition of Software

Software instructs computers what to do
A computer program, code, or algorithms is a part of software
The data structures are necessary for running the computer system

Coordination between Software and Hardware

Software manages and communicates with hardware
Example: Playing a video involves hardware and software working together

Categories of Software

Operating System (OS): Manages hardware and software on a device
Application Software: Tools for specific tasks (e.g., writing documents, browsing the internet)
Middleware: Connects different software programs
Development Software: Used to create other software or applications (e.g., programming languages, code editors)

Operating System (OS)

Core software for managing hardware and software on a device
Responsibilities:
- Manages user interface (icons, menus, windows)
- Simplifies complex processes for users
- Manages computer resources (processor, RAM, storage)
- Prevents system overload

Examples of Operating Systems

Windows: The market leader in personal computers
macOS: Known for an elegant interface, found in Apple computers
Linux: Preferred by developers for its flexibility and customization

Types of Operating Systems

Desktop OS: Manages hardware, provides services for programs, handles work, entertainment, programming
- Windows: Most used, present in most PCs
- macOS: Known for a sleek interface, used in Apple computers
- Linux: Preferred by developers for its customization and flexibility
Mobile OS: Optimized for touch interfaces, user friendly experience
- Android: Global leader in the smartphone market, available on many devices
- iOS: Known for its design, security, and features like email masking
Embedded OS: Specialized software for specific devices, focuses on efficiency and resource consumption
- Specialized devices: GPS, vehicle diagnostics, appliances
- Minimalistic design: Optimized for specific tasks
- Single purpose: Dedicated to a single function
Cloud-based OS: Runs through the internet, relies on online services rather than local hardware
- Chrome OS: Lightweight, fast, and ideal for simple tasks

How the Operating System Works

An operating system acts as a middleman between the user and the hardware
It interprets user actions and executes through hardware
Example: Playing a video involves user, Operating System, and hardware interaction

Application Software

Applications help accomplish specific tasks
Types:
- Office Applications (e.g., Word, Excel)
- Multimedia Applications (e.g., VLC, Spotify)

Categories of Applications (Meeting Specific Needs)

Office Applications: Essential for work, school, or home use (e.g., Microsoft Word, Excel)
Multimedia Applications: Designed for watching videos or listening to music (e.g., VLC, Spotify)
Video Games: For entertainment and competitive e-sports, (e.g., FIFA, Dota, Minecraft)
Business Applications: Specialized software for managing internal business processes (e.g., SAP, CRM)

Middleware

Software that enables communication between different systems or applications
Ensures smooth interactions, even if different technologies or languages are used
Bridges between software and hardware, and between applications

Software Development Tools

Code Editors: Tools for writing and editing code efficiently (e.g., Visual Studio, PyCharm)
Compilers: Convert code into executable programs (e.g., GCC, Clang)
Debuggers: Tools for identifying and fixing errors in code (e.g., GDB)

Programming Languages

Programming languages are tools for writing instructions for computers
Used to translate instructions for computer tasks, from complex algorithms to simple math equations
The most popular programming languages include:
- Java
- Python
- C++

Different Types of Programming Languages

Low-Level Languages: Closest to machine code, direct communication with hardware, but harder for humans to understand (e.g., assembly language)
High-Level Languages: Easier for humans to understand; abstract level compared to machine code, don't necessarily require understanding hardware (e.g., Python, Java)
Scripting Languages: Automate tasks, (e.g., JavaScript, Python)
Specialized Languages: For specific domains or tasks (e.g., SQL, MATLAB)

SQL (Structured Query Language)

Specialized database language used to interact with databases efficiently
Used for adding, modifying, deleting, and searching data

MATLAB

High-level language for numerical computing often used in science, engineering, and math; excels in matrix operations

Advantages of Specialized Languages

Performance Optimization (efficient within their domain and area)
Easy Implementation (simplified syntax tailored for specific needs)
Increased Productivity (for targeted applications, avoiding reinventing solutions )

Popular Programming Languages

C++: Known for high performance, versatility, portability, and strong community support
Java: Main language for enterprise software, Android apps, known for portability and stability

Python

Popular programming language known for being easy to learn and have a strong community
For many applications including building websites, artificial intelligence models, and analyzing data

Advantages of Java

High portability, stable and is widely used for Android applications

Advantages of C++

High performance in terms of speed and execution
Used in areas like videos games, embedded systems, graphic engines

Other Key Concepts

Registers: Special storage locations within the CPU.
Memory: Storage system for both data and instructions.
Instructions: Small commands the computer executes.
Hardware: Physical components of the computer.
Software: Instructions that tell the hardware what to do.
