🔍 What Is IT Architecture?
IT architecture refers to the structured framework used to manage and align an organization’s IT assets, people, operations, and projects with its overall business goals. It includes hardware, software, network resources, and services that work together to deliver IT solutions and services.
🧩 Key Components of IT Architecture
1. 🖥 Operating Systems (OS)
- Purpose: Manage computer hardware and software resources.
- Examples: Windows, macOS, Linux, Android, iOS.
- Why It Matters: Every application runs on an OS, making it the foundation of all IT operations.
2. 🗄 Servers
- Purpose: Provide centralized computing power and data access to other devices.
- Types: Web servers, database servers, file servers.
- Example: A database server storing user data for an online banking system.
3. 🌐 Network Infrastructure
- Purpose: Enables communication between devices and systems.
- Components: Routers, switches, firewalls, access points.
- Example: A company’s internal LAN (Local Area Network) connecting departments.
4. 💻 End-User Devices
- Purpose: Devices used by employees or customers to interact with IT systems.
- Examples: Desktops, laptops, tablets, smartphones.
- Role: These devices serve as the “front line” of interaction with applications and services.
⚙️ Why Understanding IT Architecture Is Essential
