Class 8 Computer Science: Concept Navigators & Chapter Diagnostic Tests Select any chapter below to use real-time computer tools and solve high-yield diagnostic questions with instant verified explanations. Interactive Concept Tool: Memory Unit Converter (Bytes to Gigabytes) Q1.Which unit of the Central Processing Unit (CPU) performs mathematical calculations and logical comparisons? Answer: (b) Arithmetic Logic Unit (ALU). The ALU executes fundamental arithmetic operations (addition, subtraction, multiplication, division) and boolean logical comparisons ($<, >, =$).
Q2.Why is RAM (Random Access Memory) termed volatile memory? Answer: (a). RAM needs continuous electrical current to maintain data. As soon as the system is powered down, all active runtime data held in RAM disappears.
Q3.Which software translates an entire high-level program into machine language all at once before execution? Answer: (c) Compiler. A compiler converts whole source code files into object machine code in a single pass, whereas an interpreter converts code line-by-line.
Interactive Concept Tool: Web Protocols & URL Anatomy Explorer Q1.What is the main difference between a Web Browser and a Search Engine? Answer: (b). A browser (Chrome, Firefox, Edge) is the client program displaying HTML pages, while a search engine (Google, Bing) indexes and queries data across the web.
Q2.What protocol automatically secures and encrypts sensitive information between a user's browser and a server? Answer: (a) HTTPS. HTTPS uses SSL/TLS encryption to shield confidential transmissions like credit cards and passwords from eavesdropping.
Q3.In the email address Answer: (c) Domain name. The part preceding '@' is the individual mailbox username, while the part following '@' is the domain host server name.
Interactive Concept Tool: Excel Function Evaluator (=SUM, =AVERAGE, =MAX, =MIN) Q1.Every formula and function in Microsoft Excel must strictly begin with which mathematical symbol? Answer: (b) Equal to sign (=). An equal sign signals to Excel that the cell contents are to be evaluated as a calculation or function rather than literal text.
Q2.What is the intersection of a vertical column and a horizontal row called in a spreadsheet? Answer: (c) Cell. A cell is the basic storage unit of a spreadsheet, referenced by its column letter followed by its row number (e.g., C5).
Q3.What will be the result of the Excel formula: Answer: (a) 10. $=SUM(5, 10, 15) = 30$, and dividing by 3 yields $30 / 3 = 10$.
Interactive Concept Tool: Slide Transitions vs. Custom Animation Inspector Q1.Which function key is pressed on the keyboard to start a PowerPoint Slide Show from the beginning? Answer: (b) F5. Pressing `F5` runs the presentation in full-screen Slide Show view from Slide 1. Pressing `Shift + F5` starts it from the current active slide.
Q2.What is the feature that applies movement and entrance/exit visual effects to individual text bullets or images on a slide? Answer: (a) Custom Animation. Animation affects individual elements on a slide, whereas Slide Transitions affect the changeover between slides.
Q3.Which PowerPoint view displays thumbnail versions of all slides simultaneously to easily rearrange their sequence? Answer: (c) Slide Sorter View. Slide Sorter view displays small thumbnails of all slides horizontally, making reordering, duplicating, or deleting slides straightforward.
