Study Notes
Introduction to ICT
- ICT stands for Information and Communication Technology.
- It encompasses all technologies used to handle information, including computing, networking, communication, and data management.
- This encompasses a wide range of tools and techniques such as computers, mobile devices, software applications, and internet services.
- ICT plays a crucial role in modern society, transforming how people communicate, work, learn, and interact with each other.
Programming Fundamentals
- Programming is the process of designing, writing, testing, and maintaining the source code of computer programs.
- It involves instructing a computer to perform specific tasks using a programming language.
Key Concepts in Programming
- Variables: Named storage locations used to hold data. Values can be modified during execution of the program.
- Data Types: Define the kind of data a variable can hold. Common types include integers, floating-point numbers, strings, and booleans.
- Operators: Symbols used to perform operations on data (e.g., arithmetic operators like +, -, *, /; logical operators like AND, OR, NOT).
-
Control Structures: Statements that control the flow of execution (e.g., conditional statements like
if-else, loops likeforandwhile).- Conditional statements determine which block of code is executed based on a condition being true or false.
- Loops (Iterations) repeat a block of code as long as a condition is true.
- Functions: Reusable blocks of code that perform specific tasks. Functions enhance code organization and reusability.
- Arrays/Lists: Ordered collections of data of the same type.
- Input/Output: Mechanisms for receiving data from the user (input) and displaying results (output).
- Debugging: The process of identifying and fixing errors (bugs) in a program.
Programming Paradigms
- Procedural Programming: Organized around procedures (functions or subroutines) that operate on data.
- Object-Oriented Programming (OOP): Data and methods are grouped into objects, encapsulating data and functions that operate on them.
- Event-Driven Programming: Programs respond to events triggered by the user or system (e.g., mouse clicks, keyboard presses).
Programming Languages
- Many programming languages exist, each designed for different purposes and with varying syntax and features.
- Examples include Python, Java, JavaScript, C++, C#, and others.
- Choosing the right language depends on the task at hand, resources, and the desired outcome.
Algorithm Design
- An algorithm is a set of instructions to solve a specific problem.
- Algorithms should be clear, unambiguous, and efficient.
- Common algorithms exist for tasks like sorting, searching, and graph traversal.
- Designing efficient algorithms is a key challenge in computer science.
- Algorithms can be expressed in pseudocode or actual code.
Software Development Lifecycle (SDLC)
- A structured approach to software development.
- Phases include requirements gathering, design, implementation, testing, deployment, and maintenance.
Importance of ICT and Programming
- ICT and programming are vital in various sectors including business, healthcare, education, and entertainment.
- Automation of tasks, streamlined communication, and improved efficiency are key advantages of using ICT.
