Class 7 Computer Science: Concept Navigators & Diagnostic Solvers Select any unit below to use live computer science tools and practice high-yield diagnostic questions with instant verified explanations before starting full-length mock tests. Interactive Concept Tool: Binary to Decimal Number Converter Q1.Which core electronic component defined the First Generation of computers (e.g., ENIAC, UNIVAC)? Answer: (a) Vacuum Tubes. First-generation computers relied on fragile, heat-producing vacuum tubes. Transistors were introduced in the 2nd generation, Integrated Circuits in the 3rd, and Microprocessors in the 4th.
Q2.What is the decimal equivalent of the binary number Answer: (c) 13. Expanding positional powers of 2: $(1 \times 2^3) + (1 \times 2^2) + (0 \times 2^1) + (1 \times 2^0) = 8 + 4 + 0 + 1 = 13$.
Q3.What is the total number of distinct symbols/digits used in the Hexadecimal Number System? Answer: (d) 16 (0 to 9 and A to F). Hexadecimal (Base 16) uses ten numeric digits (0–9) and six alphabetical letters (A=10, B=11, C=12, D=13, E=14, F=15).
Interactive Concept Tool: Storage Hierarchy & Access Speed Inspector Q1.What type of system program loads the operating system into RAM when the computer is powered on? Answer: (b) Bootstrap Loader (BIOS/UEFI stored in ROM). The booting process begins by executing BIOS firmware stored in non-volatile ROM, which tests hardware (POST) and loads the OS kernel into main memory.
Q2.Which peripheral device is both an input and an output device? Answer: (c) Touch Screen Display. A touch screen accepts user gestures/finger taps as input commands while simultaneously rendering graphic visual output.
Q3.In Microsoft Windows, which built-in administrative tool allows you to inspect active processes and terminate frozen applications? Answer: (d) Task Manager (Ctrl + Shift + Esc). Task Manager provides real-time tracking of CPU, memory, and disk usage by apps, letting users forcibly end non-responding tasks.
Interactive Concept Tool: Language Translator & Compiler vs. Interpreter Guide Q1.In Microsoft Excel, what is the purpose of the $ symbol in a formula like Answer: (c) Creates an Absolute Cell Reference that remains fixed when copied. The dollar sign locks row and column coordinates so they do not shift relatively across adjacent cells.
Q2.Which feature in MS Word is used to generate personalized letters, certificates, and envelopes for multiple recipients from a data source? Answer: (b) Mail Merge. Mail Merge merges a primary document with a structured recipient list (data source) to automate bulk generation of personalized letters or labels.
Q3.Programming languages that use human-readable English words and mathematical notations (e.g., Python, Java) are classified as: Answer: (a) High-Level Languages (HLL). High-level languages are portable and easy for humans to read and write. They require translation into machine code before execution by the CPU.
Interactive Concept Tool: Network Topology & Architecture Selector Q1.What is an attempt to trick users into revealing sensitive credentials (such as passwords or bank OTPs) via fake emails or cloned websites called? Answer: (b) Phishing. Phishing involves fraudulent communications crafted to look like reputable sources to steal confidential personal data.
Q2.Which network security barrier monitors incoming and outgoing traffic to block unauthorized external access? Answer: (c) Firewall. A firewall can be software- or hardware-based; it enforces access rules to protect private local networks from unauthorized Internet intruders.
Q3.What type of computer network spans across cities, countries, or the entire globe (e.g., the Internet)? Answer: (d) WAN (Wide Area Network). While LAN covers a single room or school campus, WAN connects geographically dispersed computational nodes across states and nations.
