Different types of OS and its sizes

Operating systems (OS) can be categorized in various ways, including their design, purpose, and the devices they run on. Here are some common types of operating systems along with a general idea of their size:

1. Desktop Operating Systems

• Windows:
  • Size: Typically 15-30 GB for installation (varies by version).
• macOS:
  • Size: Approximately 12-20 GB for installation (varies by version).
• Linux Distributions (e.g., Ubuntu, Fedora):
  • Size: Generally 1-4 GB for installation, depending on the distribution.

2. Mobile Operating Systems

• Android:
  • Size: Varies widely; stock Android can be around 5-10 GB, but OEM versions may be larger.
• iOS:
  • Size: Typically around 5-10 GB for installation, depending on the version.

3. Server Operating Systems

• Windows Server:
  • Size: Approximately 10-30 GB for installation, depending on the version.
• Linux Server Distributions (e.g., CentOS, Ubuntu Server):
  • Size: Generally 1-2 GB for minimal installations, larger for full-featured versions.

4. Embedded Operating Systems

• RTOS (Real-Time Operating Systems):
  • Size: Can be as small as a few kilobytes to several megabytes, depending on the complexity.
• Embedded Linux:
  • Size: Can be customized to be very small, often under 10 MB.

5. Network Operating Systems

• Novell NetWare:
  • Size: Historically around 100 MB, but varies by version.
• Windows Server:
  • Size: Similar to other server OS, around 10-30 GB.

6. Virtualization Operating Systems

• VMware ESXi:
  • Size: Approximately 300-500 MB for installation.
• Microsoft Hyper-V:
  • Size: Part of Windows Server, so similar size (10-30 GB).

7. Specialized Operating Systems

• Scientific Operating Systems:
  • Size: Varies widely based on the specific OS and its applications.
• Gaming Consoles (e.g., PlayStation, Xbox):
  • Size: Typically 10-20 GB for the OS, but can vary.
