10+ Progressive Infovision Interview Questions and Answers

The statement is incorrect. Routers route between different networks, while switches connect devices within the same network.

• Routers route traffic between different networks based on IP addresses

• Switches connect devices within the same network based on MAC addresses

• Example: A router connects a home network to the internet, while a switch connects devices within the home network

Public IP is the address assigned to a device connected to a network, accessible over the internet. Private IP is used within a private network.

• Public IP is unique and globally routable

• Private IP is used within a local network and not accessible over the internet

• Public IP allows devices to communicate with other devices on the internet

• Private IP allows devices to communicate within the local network

• Example of public IP: 203.0.113.1

• Example of private IP: 192.168.0.1

Troubleshooting involves identifying and resolving technical issues in computer systems and networks.

• Identify the problem by asking questions and gathering information

• Use diagnostic tools to isolate the issue

• Apply appropriate solutions to resolve the problem

• Test the system to ensure the issue has been resolved

• Document the problem and solution for future reference

STP stands for Spanning Tree Protocol, a network protocol used to prevent loops in Ethernet networks.

• STP is used to create a loop-free logical topology in a network.

• It works by selecting a root bridge and calculating the shortest path to reach each network segment.

• STP uses a tree-like structure to block redundant paths and ensure data flows efficiently.

• It helps in preventing broadcast storms and improving network stability.

• STP is defined by the IEEE 802.1D standard.

A desktop support engineer is responsible for providing technical support to end-users for hardware, software, and networking issues.

• Troubleshooting and resolving hardware and software issues

• Installing and configuring computer systems

• Setting up and maintaining network connections

• Providing technical support to end-users via phone, email, or in person

• Training end-users on new technologies or software applications

ADID stands for Automatic Device Identification. It is a feature that allows printers to automatically identify and configure themselves on a network.

• ADID helps in simplifying the process of adding printers to a network by automatically detecting and configuring them.

• It eliminates the need for manual configuration of printers on a network.

• ADID is commonly used in enterprise environments where multiple printers need to be added to a network.

• Example: When a new printer is conne...read more

Routers connect multiple networks together, while switches connect devices within a single network.

• Routers operate at the network layer (Layer 3) of the OSI model, while switches operate at the data link layer (Layer 2).

• Routers use IP addresses to forward data between networks, while switches use MAC addresses to forward data within a network.

• Routers determine the best path for data packets to reach their destination, while switches simply forward data to the appropriate devi...read more

Installation of various software involves understanding system requirements, compatibility, and following installation procedures.

• Check system requirements before installation

• Ensure compatibility with existing software

• Follow installation procedures carefully

• Test software functionality after installation

• Document installation process for future reference

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.

• The OSI model stands for Open Systems Interconnection model.

• It helps in understanding how different networking protocols work together.

• Each layer has a specific function and communicates with the layers above and below it.

• Examples of layers include physical layer, data link layer, network layer, transport layer, session layer, presenta...read more

The query is the initial request for assistance from a user, and issue resolution involves identifying and fixing the problem to restore functionality.

• Listen carefully to the user's query to understand the issue

• Troubleshoot the problem by identifying possible causes

• Implement solutions to resolve the issue

• Test the solution to ensure functionality is restored

The OSI model consists of 7 layers that define the functions of a network.

• The 7 layers of the OSI model are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and protocols associated with it.

• For example, the Physical layer deals with the physical connection between devices, while the Application layer handles user interfaces.

Informatica is a data integration tool used for extracting, transforming, and loading data from various sources.

• Used for data integration and ETL processes

• Supports various data sources such as databases, flat files, and cloud applications

• Provides a graphical user interface for designing and managing data integration workflows

• Offers advanced features such as data profiling, data quality, and metadata management

The OS (Operating System) is the software that manages computer hardware and software resources and provides common services for computer programs.

• The OS acts as an intermediary between the computer hardware and software applications.

• It provides services such as file management, memory management, process management, and device management.

• Examples of popular OS include Linux, Windows, macOS, and Android.
