Study Notes
Intangible & Logic
- Software is a collection of instructions that tell a computer how to perform tasks.
- Software is unlike hardware, which is the physical components of a computer.
- Software includes data, applications, and operating systems that allow users to interact with and operate the computer.
Overview
- Topics for the chapter include:
- What is software?
- Differences between software and hardware
- High-level programming
- Software Development Life Cycle (SDLC)
- Programs and applications: Productivity, Graphics, Security, and others
What is Software?
- Software is a set of instructions or programs that operate on the hardware of a computer.
- It enables the hardware to perform its functions.
Types of Software
- System software: Manages and controls hardware, allowing other software to function. Operating systems (like Windows, macOS, or Linux) are examples.
- Application software: Helps users perform specific tasks. Examples include word processors, web browsers, and media players.
- Programming software: Provides tools for developers to create other software. Examples include compilers, interpreters, and IDEs (Integrated Development Environments) like Visual Studio.
System Software
- This type of software controls hardware.
- Operating systems (OS) manage hardware and enable other software to function.
Application Software
- Application software helps users with specific tasks.
- Examples include word processors, web browsers, and media players.
Programming Software
- Programming software supports developers.
- Tools like compilers and IDEs are examples.
Difference of Software and Hardware
- Software is the set of instructions or programs that run on hardware.
- Hardware is the physical machinery or equipment that executes instructions given by software.
Programming Languages
- Different types of programming languages exist.
- High-level languages are easier for humans to read, write, and understand.
- They include Python, Java, C++, Ruby, and JavaScript.
- Low-level languages are closer to machine code and directly interact with the hardware.
- Examples include Machine Language and Assembly Language
High-Level Programming
- A high-level programming language is designed for human readability, unlike low-level languages.
- It abstracts away the complex details of the computer's hardware, making programming more accessible and efficient.
Types of High-Level Programming Languages
- Python (known for readability and ease of use, often used in web development, data science, and automation)
- Java (a platform-independent language, widely used in enterprise applications, Android development, and web applications)
- C++ (an extension of C, used in systems programming, game development, and applications requiring high performance)
- JavaScript (primarily used for web development to make websites interactive)
- Ruby (known for simplicity and productivity, often used in web development)
Low-Level Programming
- A low-level programming language provides little abstraction from the computer's hardware.
- Low-level languages directly deal with the computer's internal workings.
- The programmer interacts with memory management, processor instructions, and hardware resources.
Types of Low-Level Programming Languages
- Machine Language (contains binary code, the lowest level)
- Assembly Language (uses mnemonics, a human-readable representation of machine instructions)
Machine Language
- Machine language is the lowest level language.
- It uses binary code (0s and 1s) to directly control the computer's hardware.
Assembly Language
- Assembly language gives programmers a human-readable way to program using mnemonics (abbreviations or symbolic names) instead of binary code.
Syntax
- Syntax defines the structure and format of valid statements in a programming language.
Compilers
- The compilation process converts high-level language programs into a form that hardware can execute.
Algorithm
- An algorithm is a step-by-step procedure to accomplish a task or solve a problem.
Software Development Life Cycle (SDLC)
- The SDLC is a structured approach for planning, creating, testing, and deploying software applications.
SDLC Models
- Waterfall Model: A sequential approach where each phase is complete before moving to the next. Good for projects with fixed requirements.
- Agile Model: An iterative and incremental approach, developing the software in short segments (iterations or sprints).
- V-Model (Verification and Validation): Similar to the Waterfall but emphasizes testing phases.
- Iterative Model: Repetitive cycles, each builds on previous cycles and improves with user feedback.
- Rapid Application Development (RAD): Methodology emphasizing rapid prototyping and quick feedback from users.
- Scrum: Agile framework used for managing software development projects.
