KT0201: Introduction to Computing Knowledge
Computing knowledge refers to understanding computer systems, software, programming, and digital technologies used in modern environments.
Computing knowledge supports:
- Software development
- Data management
- Automation
- Communication
- Digital business operations
Modern organisations depend heavily on computing technologies to operate efficiently.
Importance of Computing Knowledge
Computing knowledge helps individuals:
- Use digital systems effectively
- Develop software solutions
- Understand web technologies
- Support digital transformation
- Improve problem solving
Computing skills are increasingly important in 4IR workplaces.
KT0202: JavaScript
JavaScript is a programming language used to add interactivity and dynamic features to websites.
Functions of JavaScript
JavaScript allows websites to:
- Respond to user actions
- Validate forms
- Display animations
- Update content dynamically
- Improve user experiences
JavaScript is widely used in web development.
Applications of JavaScript
Examples include:
| Application | Example |
|---|---|
| Interactive Forms | Online registration forms |
| Web Animations | Interactive graphics |
| Games | Browser-based games |
| Dynamic Websites | Live content updates |
JavaScript improves website functionality and interactivity.
KT0203: PHP in Web Technology
PHP stands for:
“PHP: Hypertext Pre-processor”
PHP is a widely used open-source scripting language executed on servers.
Functions of PHP
PHP is used to:
- Develop websites
- Process forms
- Connect to databases
- Generate dynamic content
- Manage web applications
PHP scripts run on the server before information is displayed to users.
Advantages of PHP
PHP offers:
- Open-source access
- Flexibility
- Server-side functionality
- Database integration
PHP is commonly used in web application development.
KT0204: SQL and NoSQL Databases
Databases store and manage information digitally.
Two common database types are:
- SQL databases
- NoSQL databases
SQL Databases
SQL stands for Structured Query Language.
SQL databases:
- Store structured data
- Use tables and rows
- Follow fixed schemas
Examples include:
- MySQL
- PostgreSQL
- Microsoft SQL Server
NoSQL Databases
NoSQL databases are designed for flexible and large-scale data storage.
NoSQL databases:
- Handle unstructured data
- Use flexible data models
- Support scalability
Examples include:
- MongoDB
- Cassandra
- Firebase
Difference Between SQL and NoSQL
| SQL | NoSQL |
|---|---|
| Structured data | Unstructured data |
| Table-based | Flexible models |
| Fixed schema | Dynamic schema |
| Relational | Non-relational |
Different databases are used according to organisational needs.
KT0205: Web Technologies
Web technologies are technologies used to create and manage websites and web applications.
Examples of Web Technologies
Examples include:
- HTML
- CSS
- JavaScript
- PHP
- Web servers
- Databases
These technologies work together to create functional websites and online systems.
Front-End and Back-End Technologies
Front-End Technologies
Front-end technologies manage what users see and interact with.
Examples:
- HTML
- CSS
- JavaScript
Back-End Technologies
Back-end technologies manage server-side operations and databases.
Examples:
- PHP
- SQL databases
- Web servers
Together, front-end and back-end technologies create complete web applications.
KT0206: Computing Knowledge in Modern Workplaces
Modern organisations use computing technologies to support:
- Communication
- Automation
- Data management
- Business operations
- Software development
Computing knowledge is essential in digital and RPA environments.
Computing and Digital Transformation
Digital transformation depends on computing systems and technologies.
Examples include:
- Cloud computing
- Web applications
- Automation systems
- Data analytics
Organisations increasingly rely on computing skills to remain competitive.
KT0207: Importance of Computing Knowledge
Computing knowledge supports:
- Innovation
- Problem solving
- Software development
- Automation
- Digital communication
Employees with computing knowledge are better prepared for modern technology-driven workplaces.
