By Delight Technical College | School of Media & AI- ICT | 2026

 

Every organisation that uses computers which in 2026 means virtually every organisation needs someone who can keep those computers running. ICT support and computer maintenance is one of the most consistently in-demand professional services in Kenya’s economy, and it is a core component of Delight Technical College’s ICT (Computer Operator) Trade Test. Here is a comprehensive guide to what this practical dimension of ICT training covers and where it leads professionally.

💻 Understanding Computer Hardware

The Main Components:

• Central Processing Unit (CPU)- the ‘brain’ of the computer, executing instructions
• Random Access Memory (RAM)- temporary storage for programs and data currently in use
• Storage- Hard Disk Drives (HDD) or Solid State Drives (SSD) for permanent data storage
• Motherboard- the circuit board connecting all components
• Power Supply Unit (PSU)- converting mains electricity to the voltages computers use
• Graphics Processing Unit (GPU)- processing visual output and increasingly AI workloads
• Input/Output devices- keyboards, mice, monitors, printers, and scanners

Common Hardware Problems and Solutions:

• Computer running slowly- RAM insufficient, storage nearly full, malware, or overheating
• Computer won’t start- power supply failure, RAM failure, or operating system corruption
• Overheating- dust accumulation in vents and fans, inadequate thermal paste
• Strange noises- failing hard drive or fan components
• Display problems- cable connection issues, graphics card failure, or monitor damage

🌍 The ICT Support Market in Kenya

Every school, church, government office, NGO, small business, and household with computers needs ICT support. As digital adoption continues to grow across Kenya, this market is expanding continuously. ICT support is particularly valuable in counties outside Nairobi where the supply of qualified technicians is lower and the need is growing.

 

“In Kenya, the person who can fix a computer quickly and reliably is one of the most valuable professionals in any community. At Delight, we train that person with the technical knowledge, the diagnostic discipline, and the professional communication skills that ICT support demands.”

💡 ICT support skills complement Microsoft Office training perfectly. Together they create a comprehensive ICT professional profile that can serve organisations of any size.
