NABARD Grade A Computer Knowledge Flashcards
60 question-and-answer cards covering Computer Knowledge as it is examined in NABARD Grade A. 24 of them are printed below, taken from across the deck — no signup, no paywall on the preview.
24 sample cards from the Computer Knowledge deck
Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.
What is a file and what is a folder (directory)?
A file is a named collection of related data stored as a unit; a folder (directory) is a container used to organize and group files and other folders.
What is a file extension and give three common examples.
A suffix after the dot in a filename indicating the file type/format; e.g., .txt (text), .jpg (image), .pdf (document).
What is a file path?
The complete address that specifies the location of a file or folder in the storage hierarchy (e.g., C:\Users\Documents\file.txt).
What is the difference between deleting a file normally and using Shift+Delete in Windows?
A normal delete moves the file to the Recycle Bin (recoverable); Shift+Delete removes it permanently, bypassing the Recycle Bin.
What is a computer network?
Two or more interconnected computers/devices that can share data, resources, and communicate with each other.
Differentiate LAN, MAN, and WAN by geographic scope.
LAN (Local Area Network) covers a small area like a building; MAN (Metropolitan Area Network) covers a city; WAN (Wide Area Network) covers large regions or countries (e.g., the Internet).
Name common network topologies.
Bus, Star, Ring, Mesh, and Tree topologies.
What is the function of a router versus a switch?
A router connects different networks and routes data between them using IP addresses; a switch connects devices within the same network and forwards data using MAC addresses.
What is the difference between a hub and a switch?
A hub broadcasts incoming data to all ports (shared bandwidth); a switch forwards data only to the intended destination port (dedicated bandwidth), making it more efficient.
What does the Internet stand for, and which protocol suite does it use?
The Internet is a global network of interconnected networks; it uses the TCP/IP (Transmission Control Protocol/Internet Protocol) suite.
What is the difference between HTTP and HTTPS?
HTTP transfers web data in plain text; HTTPS adds an SSL/TLS encryption layer, making the communication secure.
What is a URL and name its main parts?
A Uniform Resource Locator is the address of a web resource; its parts include the protocol (https://), domain name (www.example.com), and path (/page).
What is the difference between authentication and authorization in cyber security?
Authentication verifies a user's identity (who you are); authorization determines what an authenticated user is permitted to access or do.
Differentiate a virus, a worm, and a Trojan horse.
A virus attaches to files and needs a host/user action to spread; a worm self-replicates and spreads across networks without a host; a Trojan horse disguises itself as legitimate software to gain access.
What is phishing?
A cyber attack where attackers impersonate trusted entities (often via fake emails or websites) to trick users into revealing sensitive information like passwords or bank details.
What is a firewall?
A network security system (hardware or software) that monitors and controls incoming and outgoing traffic based on predefined security rules to block unauthorized access.
What is encryption?
The process of converting readable data (plaintext) into an unreadable coded form (ciphertext) so only authorized parties with the key can read it.
What is cloud computing?
The delivery of computing services such as storage, servers, and software over the Internet on demand, typically on a pay-as-you-use basis.
What are the three main service models of cloud computing?
IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service).
What is Artificial Intelligence (AI)?
The branch of computer science focused on building machines and systems capable of performing tasks that normally require human intelligence, such as learning, reasoning, and decision-making.
What is the Internet of Things (IoT)?
A network of physical devices embedded with sensors and software that connect and exchange data over the Internet (e.g., smart appliances, wearables).
What is Blockchain technology?
A distributed, decentralized digital ledger that records transactions across many computers in linked, tamper-resistant blocks, ensuring transparency and security.
What is Big Data?
Extremely large and complex datasets that traditional tools cannot process efficiently, often described by the characteristics Volume, Velocity, and Variety.
What is Machine Learning and how does it relate to AI?
Machine Learning is a subset of AI that enables systems to learn patterns from data and improve performance automatically without being explicitly programmed for every task.
What this deck covers
The Computer Knowledge deck follows the NABARD Grade A Computer Knowledge syllabus — 3 chapters and 10 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 20.0 cards per chapter.
Answers are written to be recallable, not just readable — averaging about 147 characters, which is long enough to carry the reasoning and short enough to say out loud.
A deck like this earns its keep on the second and third pass. Read the syllabus first so you know the shape of the subject, then use the cards to find the specific facts that have not stuck.
Computer Knowledge flashcards FAQ
How many Computer Knowledge flashcards are in this NABARD Grade A deck?
60 cards. This page previews 24 of them, sampled evenly across the deck so you can judge the difficulty before installing anything.
Are these NABARD Grade A flashcards free?
Yes. The preview here is free to read with no signup, and the full 60-card deck is free inside the Examius app.
What do the Computer Knowledge cards cover?
They follow the NABARD Grade A Computer Knowledge syllabus — 3 chapters and 10 topics — so the questions track what is actually examinable.
How should I use these flashcards?
Read the syllabus first so you know the shape of the subject, then drill the deck. Examius schedules each card with spaced repetition, so cards you keep missing come back sooner and ones you know drift further apart.
