It enables data exchange, shared file access, and use of common peripherals like printers. Networks range from small home setups to large enterprise infrastructures.  \nQ2 What is the difference between LAN and WAN?  \n● LAN ( Local Area Network): Connects devices within a limited area like a home, office, or school. High-speed, low-cost, shorter distances.  \n● WAN (Wide Area Network): Spans large geographic areas-cities, countries, or globallyusing the internet or leased lines to link remote locations.  \nQ3 What is an IP address?  \nAn IP (Internet Protocol) address is a unique numerical label assigned to each device on a network, enabling it to send and receive data.  \n● IPv4: 32-bit address (e.g., 192.168.1.1)—supports ~4.3 billion addresses  \n● IPv6: 128-bit address—designed to replace IPv4 with vastly more address space  \nQ4 How does DHCP work?  \nDHCP ( Dynamic Host Configuration Protocol) automatically assigns IP addresses to devices joining a network.  \nA device sends a DHCP Discover broadcast → the server responds with an available IP and leases it for a set duration. This eliminates manual configuration and reduces administrative overhead.  \nQ5 What is the OSI model?  \nThe OSI (Open Systems Interconnection) mode l is a conceptual 7-layer framework that standardizes how network components communicate.  \nEach layer handles a specific function from physical signal transmission to application-level interfaces helping engineers design, understand, and troubleshoot networks.  \nQ6 Name the 7 layers of the OSI model and their functions.  \nFrom bottom to top:  \n● Layer 1 – Physical: Transmits raw bits via cables or wireless signals  \n● Layer 2 – Data Link: Error-free transmission between directly connected nodes  \n● Layer 3 – Network: Routes packets across networks (IP lives here)  \n● Layer 4 – Transport: Reliable end-to-end delivery (TCP/ UDP lives here)  \n● Layer 5 – Session: Manages connections between applications  \n● Layer 6 – Presentation: Data formatting, encryption, and compression  \n● Layer 7 – Application: Network services for apps like [HTTP](HTTP), DNS, FTP  \nQ7 What is TCP/IP?  \nTCP/IP is the foundational communication protocol suite of the internet.  \n● TCP (Transmission Control Protocol): Ensures reliable, ordered, error-checked delivery  \n● IP (Internet Protocol): Handles addressing and routing of packets between networks Together, they defi ne how data is packaged, addressed, transmitted, and received.  \nQ8 What is the function of a router?  \nA router forwards data packets between different networks. It reads each packet's destination IP address and uses routing tables to select the best path forward.  \nRouters are essential for connecting networks, managing traffic, and enabling internet communication.  \nQ9 What is the difference between a hub and a switch?  \n● Hub: Broadcasts all incoming data to EVERY connected device-causes collisions, inefficient  \n● Switch: Forwards data only to the INTENDED device using its MAC address- reduces collisions, improves performance  \nSwitches are the standard choice for modern networks due to their targeted, efficient data delivery.  \nQ10 What is a MAC address?  \nA MAC ( Media Access Control) address is a unique 48-bit hexadecimal hardware identifier assigned to each network interface card ( NIC) by its manufacturer.  \nIt acts as the physical address of a device on a local network. Switches use MAC add","cbCaim22nYOdDW6f","https://ap.wps.com/l/cbCaim22nYOdDW6f","pdf",312032,15,"English","# Networking Interview Questions with Answers\n## Networking Interview Questions for Freshers (Entry Level)\n## Core Networking Concepts (LAN, WAN, IP, DHCP, OSI, TCP/IP)\n## Network Devices and Protocols (Router, Hub vs Switch, MAC, ARP, DNS)\n## Addressing and Network Design (Subnet Mask, Subnetting, CIDR, NAT)","[{\"question\":\"What is a computer network?\",\"answer\":\"A computer network is a group of interconnected devices that communicate and share resources, enabling data exchange and common peripherals like printers.\"},{\"question\":\"What are the key differences between LAN and WAN?\",\"answer\":\"LAN connects devices within a limited area such as a home, office, or school, while WAN spans large geographic areas like cities or countries using the internet or leased lines.\"},{\"question\":\"How does DNS work when a user enters a URL?\",\"answer\":\"The browser queries a DNS resolver, the resolver contacts DNS servers to return the IP address, and then the browser connects to the correct server.\"}]","Networking Interview Questions - A Complete Guide for Recruiters, Hiring Managers & Candidates | PDF",1790351750,38]
