1. What is a Network? (Common network interview questions)
A network refers to the interconnection of multiple devices, often called nodes, which communicate and transfer data through physical or wireless connections. Networks are essential in facilitating efficient communication and collaboration between devices within an organization or across the internet.
2. What are the different types of networks?
There are several types of networks based on their size, geographical reach, and purpose:
- Personal Area Network (PAN): A small network covering a short range like Bluetooth devices.
- Local Area Network (LAN): Covers a limited area like offices or homes.

- Wide Area Network (WAN): Covers a large geographical area like countries or continents.
- Virtual Private Network (VPN): Provides secure access to remote resources via encrypted connections.
3. What is the OSI Model?
The Open Systems Interconnection (OSI) model is a conceptual framework that standardizes the functions of different networking protocols into seven distinct layers. Each layer performs specific tasks and interacts with adjacent layers to provide seamless communication between networked devices.
4. Explain the Seven Layers of OSI Model
The OSI model comprises seven layers:
- Physical Layer: Transmits raw bitstream over the physical medium like cables or wireless signals.
- Data Link Layer: Manages error-free transmission between adjacent nodes by providing error detection and control mechanisms.

5. What is the TCP/IP Model?
The Transmission Control Protocol/Internet Protocol (TCP/IP) model is a simpler networking framework that defines how data should be transmitted over networks. It consists of four layers:
