Networked Systems — File Server Characteristics Which statement best describes a core characteristic of a file server in a distributed environment?

Introduction:
File servers are foundational components in networked computing. They centralize storage and file-system services so that multiple client machines can read, write, and share files over a local or wide area network. This question checks your understanding of what a file server actually does versus the roles of clients and application servers.

Given Data / Assumptions:

• A file server exposes shared folders and files to multiple client machines.
• Clients access files via standard protocols (for example, SMB/CIFS, NFS).
• Application logic typically runs on the client or a separate application server, not on the file server.
• The term “fat client” refers to client machines doing substantial local processing, not to the server.

Concept / Approach:
The essence of a file server is centralized file-system management and network sharing. Clients authenticate, then open, read, and write files through the server, which handles permissions, locking, and I/O scheduling. By contrast, an application server executes business logic, while a database server manages structured data and queries.

Step-by-Step Solution:
1) Identify which option emphasizes centralized file operations available to multiple users.2) Eliminate options that incorrectly describe the server as a “fat client.”3) Eliminate options that limit the server to a single PC, which contradicts its networked nature.4) Select the option that matches a shared, network-accessible file service role.

Verification / Alternative check:
In common deployments, Windows Server with SMB shares or Linux with NFS exports illustrate exactly this centralized sharing model accessed by many clients concurrently.

Why Other Options Are Wrong:

• Limited to one PC: Contradicts the idea of network sharing.
• Acts as a fat client: A server is not a “client”; fat clients are endpoints doing heavy local processing.
• Fat client and limited/shared: Mislabels the server role entirely.

Common Pitfalls:
Confusing a file server with an application or database server and assuming it runs end-user business logic.

Final Answer:
Manages file operations and is shared on a network.
