Server – The Engine of the Internet

At its core, a server is a high-performance computer designed to run 24/7 without being turned off. Unlike a laptop or desktop, a server usually doesn’t have a screen or keyboard attached; it’s accessed remotely by engineers and automated systems.

1. What Makes a Server "Powerful"?

While a server has the same basic components as your home computer (CPU, RAM, and Storage), they are built with Enterprise-Grade parts for reliability and performance:

• Reliability: Servers use redundant parts. For example, if one power supply fails, a backup activates immediately to prevent downtime.
• Performance: Specialized processors (Intel Xeon, AMD EPYC) handle thousands of visitors simultaneously.
• Storage Speed: Jiinubi servers use NVMe SSDs, which are much faster than standard hard drives, ensuring website loads in milliseconds.

2. The "Client-Server" Relationship

The internet works on a simple request-and-response model:

• The Client: The visitor’s web browser (Chrome, Safari, etc.).
• The Request: When a visitor clicks your link, the browser asks the server for your files.
• The Server: Listens for requests, finds the correct files, and serves them back to the client.

3. Physical Location: The Data Center

Servers are stored in highly secure, climate-controlled buildings called Data Centers. These facilities provide:

• Industrial Cooling: Prevents servers from overheating.
• Physical Security: Biometric locks and 24/7 surveillance.
• Connectivity: High-speed fiber-optic lines connect servers to the internet.

4. Physical Server vs. Virtual Server

Modern hosting often uses Virtualization to maximize server power:

• Bare Metal (Physical): One customer uses the entire physical machine.
• Virtual Server (VM): One physical server is split into multiple virtual servers. Each acts like a real computer with its own OS but shares underlying hardware.
