1: Computer Hardware & Maintenance

This section focuses on the physical components, assembly, and repair of desktop and laptop systems.

Computer Fundamentals: History of computers, generations, and basic architecture (Input/Output/Processing units)

.Electronics (Analog & Digital): Basic electricity, resistors, capacitors, and using a Multimeter to test power.

Microprocessors: Understanding CPU architectures (Intel vs. AMD), sockets, and clock speeds.Motherboard & 

Components: Study of Chipsets, BIOS/UEFI settings, CMOS, and expansion slots (PCIe, RAM slots).

Assembling & Disassembling: Hands-on practice of building a PC from scratch and cable management.

Storage Technologies: Differences between HDD, SSD, and NVMe; RAID configurations for data backup.

Peripheral Devices: Installation and troubleshooting of Printers (Laser, Inkjet), Scanners, and Monitors.

 

 2: Operating Systems & Software

You cannot run hardware without software. This module covers how to manage the "brain" of the computer.

OS Installation: Installing Windows (10/11), Linux (Ubuntu/RedHat), and Server OS.

Dual Booting: Configuring a single machine to run two different operating systems.

Device Drivers: Finding, installing, and updating drivers for graphics, sound, and network cards.

System Troubleshooting: Using Safe Mode, Registry Editor (Regedit), and System Restore to fix software crashes.

Disk Management: Partitioning drives, formatting, and file systems (FAT32 vs. NTFS).

 

 3: Networking Fundamentals (N+)

This is the core of "connectivity," teaching you how to link multiple computers together.

Networking Models: Detailed study of the OSI Model (7 Layers) and TCP/IP Model.

IP Addressing: Understanding IPv4 and IPv6, Subnetting, and Public vs. Private IPs.

Network Hardware: Configuring and managing Hubs, Switches, Routers, and Access Points.

Cabling: Practical skills in crimping RJ45 connectors and setting up LAN cables (Straight-through vs. Crossover).

Network Topologies: Designing Star, Mesh, and Ring network layouts.

 

 4: Advanced Networking & Security

The final months usually cover corporate-level infrastructure and protection.

Server Administration: Basic Windows Server management, creating User Accounts, and Active Directory.

Network Services: Setting up DHCP (Auto-IP), DNS (Domain names), and FTP (File transfer).

Network Security: Introduction to Firewalls, VPNs (Virtual Private Networks), and protecting against malware.

Wireless Networking: Configuring Wi-Fi routers, security protocols (WPA2/WPA3), and range extenders.
