Answer 1

The Correct Option is A

Concept: A Network Operating System (NOS) is designed to manage network resources and provide services to multiple computers connected through a network. Functions of a NOS include:
• User management
• File sharing
• Printer sharing
• Network security
• Remote access

Step 1: Analyze Unix.
Unix supports multiuser networking, remote access, and network services. Therefore, \[ \text{Unix} \rightarrow \text{NOS} \]

Step 2: Analyze Windows Server.
Windows Server is specifically designed for network administration and enterprise environments. \[ \text{Windows Server} \rightarrow \text{NOS} \]

Step 3: Analyze Linux.
Linux supports extensive networking capabilities and is widely used as a server operating system. \[ \text{Linux} \rightarrow \text{NOS} \]

Step 4: Analyze Android.
Android is primarily a mobile operating system designed for smartphones and tablets. Although it supports networking features, it is not categorized as a Network Operating System. \[ \boxed{\text{Android}} \] Hence, option (A) is correct.
