Diploma in Information Technology

Cullen University College – in affiliation with Mosa University

Duration: Few Months | Level: Diploma

Course Introduction

Information Technology underpins virtually every modern organization banks, telecoms, government ministries, mining operations, hospitals, and small businesses alike depend on functioning computer systems, networks, databases, and increasingly, cloud infrastructure and cybersecurity. Zambia’s digital economy is expanding rapidly, driven by mobile money infrastructure, government e-services initiatives under the Smart Zambia Institute, growing ISP and telecom investment, and an increasingly tech-literate younger workforce creating genuine, sustained demand for IT professionals across systems administration, networking, support, and development roles.

This diploma provides a comprehensive, technically rigorous foundation across the core pillars of Information Technology computer hardware and systems, operating systems administration, networking, programming, databases, web technologies, cybersecurity, cloud computing, and IT service/project management building directly on and expanding beyond the foundational content in Cullen’s Certificate in Software Engineering and Certificate in Introduction to Computer Skills. Every module combines internationally recognized technical standards with genuine, hands-on worked examples and Zambian regulatory and industry context, positioning graduates for real IT support, administration, and junior development roles, or further specialized study.

Learning Outcomes

By the end of this diploma, you will be able to:

• Explain computer hardware components and binary/data representation fundamentals
• Install, configure, and administer common operating systems using command-line and GUI tools
• Design, configure, and troubleshoot basic computer networks, including IP addressing and subnetting
• Write functioning programs and understand core software development principles
• Design relational databases and write SQL queries to manage data
• Build and understand core web technologies and how web applications function
• Apply fundamental cybersecurity principles to protect systems and data
• Explain cloud computing service models and basic virtualization concepts
• Apply IT service management (ITIL-aligned) and project management principles to IT operations

Who this course is for: Aspiring IT support technicians, systems/network administrators, help desk staff, and anyone seeking a genuinely broad, technically grounded IT diploma as a foundation for employment or further specialized study (networking certifications, cybersecurity certifications, or further software development study). Completion of Cullen’s Certificate in Introduction to Computer Skills, or equivalent basic computer literacy, is recommended though not strictly required.
