+### Operating System
+
+```bash
+lsb_release -a
+```
+
+```bash
+No LSB modules are available.
+Distributor ID: Ubuntu
+Description:    Ubuntu 24.04.3 LTS
+Release:        24.04
+Codename:       noble
+```
+
+### Virtualization Detection
+
+
+```bash
+systemd-detect-virt
+```
+
+```bash
+oracle
+```
+
+The most useful tools were `lscpu`, `free -h`, `ip a`, `df -h`, `lsb_release -a` and `systemd-detect-virt`:
+- `lscpu` was very helpful because it provides detailed CPU information in a clear and structured format
+- `free -h` quickly shows total and available memory in a human-readable way, which makes RAM analysis simple
+- `ip a` is essential for checking network interfaces and assigned IP addresses
+- `df -h` clearly displays disk usage and filesystem information
+- `lsb_release` - a was very useful because it clearly shows the Ubuntu distribution version, release number, and codename. This is important for verifying that the correct OS version is installed
+- `systemd-detect-virt` was especially useful to confirm that the system is running inside  a VirtualBox virtual machine
