IT Course

Lesson 1 • Data Representation and Storage

Explains how text, images, and audio are encoded digitally. Grounds students in data formats before introducing networking and databases.

Lesson 2 • Input, Output, and Peripherals

Surveys input/output devices and their interfaces. Prepares students to configure and troubleshoot peripheral connections.

Lesson 3 • Core Hardware Components

Examines CPU, RAM, storage, and motherboard functions. Connects physical components to system performance and reliability.

Lesson 4 • Understanding Computers and Computing

Defines computing, binary logic, and the role of hardware vs. software. Establishes the conceptual baseline for all subsequent technical content.

Lesson 1 • IP Addressing and Subnetting

Teaches IPv4 and IPv6 addressing, CIDR notation, and subnet calculation. Directly supports network configuration tasks in later chapters.

Lesson 2 • Network Models and Concepts

Presents the OSI and TCP/IP models as frameworks for understanding communication. Links each layer to real protocols and devices.

Lesson 3 • Physical and Logical Topologies

Compares wired and wireless media, topologies, and their trade-offs. Enables informed infrastructure design decisions.

Lesson 4 • Core Network Devices

Distinguishes hubs, switches, routers, and access points by function. Prepares students to select and configure appropriate devices.

Lesson 1 • OS Installation and Configuration

Walks through pre-installation planning, partitioning, and post-install setup. Builds the procedural foundation for all OS management tasks.

Lesson 2 • System Updates and Patch Management

Covers update mechanisms, patch testing, and rollback procedures. Establishes a disciplined maintenance cycle that reduces vulnerability exposure.

Lesson 3 • User and Group Management

Covers account creation, group policies, and privilege levels. Directly supports access control and security hardening in later chapters.

Lesson 4 • File System Permissions

Explains permission models for major OS platforms and inheritance rules. Enables students to enforce least-privilege access on shared resources.

Lesson 1 • Common Threats and Attack Vectors

Surveys malware types, social engineering, and network-based attacks. Builds threat recognition skills needed for risk assessment.

Lesson 2 • Security Policies and Compliance

Explains acceptable-use policies, audit requirements, and regulatory frameworks. Prepares students to align technical controls with organisational governance.

Lesson 3 • Endpoint and Application Security

Addresses antivirus, host-based firewalls, and secure coding basics. Extends protection from the network perimeter to individual devices.

Lesson 4 • Security Concepts and Principles

Introduces the CIA triad, authentication factors, and defence-in-depth. Frames all subsequent security topics within a unified conceptual model.

Lesson 1 • Querying and Filtering Data

Teaches SELECT, WHERE, JOIN, and aggregate functions. Enables students to extract meaningful insights from relational data.

Lesson 2 • Relational Database Fundamentals

Defines tables, keys, relationships, and normalisation forms. Provides the structural knowledge required before writing any SQL.

Lesson 3 • Database Indexing and Performance

Explains index types, query execution plans, and optimisation techniques. Connects schema design decisions to measurable query performance.

Lesson 4 • Backup, Recovery, and Security

Covers backup strategies, transaction logs, and database user permissions. Ensures students can protect and restore critical data assets.

Lesson 1 • Python for IT Automation

Covers Python syntax, standard libraries, and file I/O for IT use cases. Extends automation capability beyond shell scripting to cross-platform tasks.

Lesson 2 • Debugging and Code Quality

Introduces debugging techniques, logging, and code review practices. Ensures students produce reliable, maintainable automation code.

Lesson 3 • Network Automation with Scripts

Applies scripting to network device configuration and monitoring. Bridges programming skills with the networking knowledge from Chapter 2.

Lesson 4 • Programming Logic and Fundamentals

Introduces variables, data types, control flow, and functions. Establishes the logical thinking required before writing any automation scripts.

Lesson 1 • Deploying and Managing Virtual Machines

Covers VM provisioning, networking, and lifecycle management in a cloud environment. Builds hands-on deployment skills applicable to any major cloud platform.

Lesson 2 • Cloud Service and Deployment Models

Compares IaaS, PaaS, and SaaS alongside public, private, and hybrid clouds. Enables informed cloud adoption decisions aligned with business needs.

Lesson 3 • Virtualization Concepts and Hypervisors

Defines Type 1 and Type 2 hypervisors, VMs, and resource isolation. Establishes the technical foundation for both on-premises and cloud deployments.

Lesson 4 • Cloud Security and Compliance

Addresses identity management, encryption, and compliance in cloud environments. Extends the security principles from Chapter 4 to cloud-specific controls.

Lesson 1 • IT Project Lifecycle and Frameworks

Compares waterfall, agile, and hybrid methodologies for IT projects. Provides the governance vocabulary needed for all subsequent planning activities.

Lesson 2 • Scope, Schedule, and Budget Planning

Teaches work breakdown structures, Gantt charts, and cost estimation. Directly enables students to build a realistic project plan.

Lesson 3 • IT Strategy and Governance

Introduces IT governance frameworks, strategic alignment, and portfolio management. Positions students to contribute to enterprise-level technology decisions.

Lesson 4 • Stakeholder and Communication Management

Addresses stakeholder mapping, communication plans, and status reporting. Ensures technical decisions are communicated effectively to non-technical audiences.
