🐧 Understanding the Linux File System Structure 📂

Ever wondered how Linux organizes its files and directories? Unlike Windows, which uses drive letters (C:, D:), Linux follows a hierarchical directory structure, starting from the root (/) directory.

💡 Key Directories in Linux:
📂 /bin – Essential binaries (commands like ls, cp, mv)
📂 /boot – Stores bootloader files and kernel images
📂 /dev – Contains device files for hardware components
📂 /etc – System configuration files 🛠
📂 /home – User home directories 🏠
📂 /var – Logs, caches, and variable data
📂 /tmp – Temporary files 🕒
📂 /root – Home directory for the root user
📂 /proc & /sys – Virtual files for system processes and hardware

🔍 Why Does This Matter?
✔ Improves file organization & system security
✔ Enhances system performance & troubleshooting
✔ Crucial for Linux admins, developers & cybersecurity professionals

Google plans to fight Starlink: a light-based connection to reach where fiber can't.

Google has already tested this technology outdoors, and the results couldn't be more positive. The company has managed to achieve speeds of 10 Gbps at a distance of 1 km , a transmission record for silicon photonics. Another interesting feature of this chip is that all of its emitters are software-controlled, allowing them to be managed and oriented automatically, resulting in significantly reduced costs.
