Computer Systems and Organisation Quiz 2

✅ Answer: (c) Operating system

An operating system is system software — it manages the computer’s hardware and provides a platform for other programs to run. Word processors, spreadsheets, and graphics editors are all application software, built for specific end-user tasks.

✅ Answer: (b) Managing computer hardware and software resources

The OS’s core job is managing hardware and software resources — memory, storage, processes, and devices — and acting as the bridge between the user and the machine.

✅ Answer: (c) Operating system

File and directory management is one of the core responsibilities of the operating system — it keeps track of where data is stored and organises it for easy access.

✅ Answer: (c) Device drivers

Device drivers are small, specialised programs written to control a specific piece of hardware (like a printer or graphics card) and let it communicate properly with the OS.

✅ Answer: (d) Enabling communication between hardware devices and the operating system

A device driver’s job is to enable communication between a hardware device and the operating system — it translates the OS’s general commands into instructions that specific hardware understands.

✅ Answer: (a) Assembler

An assembler is the language translator specifically built to convert assembly language (mnemonics like MOV, ADD) into machine code (binary).

✅ Answer: (b) Compiler

A compiler takes an entire high-level language program (like C++) and translates it into machine code all at once, before execution begins.

✅ Answer: (c) Interpreter

An interpreter translates and executes code one line at a time, rather than compiling the whole program first — that’s why errors in interpreted languages show up as soon as the faulty line runs.

✅ Answer: (a) Python

Python is a classic example of an interpreted language — the Python interpreter reads and runs code line by line. C++ is compiled, and Java uses a compiler-plus-JVM combination.

✅ Answer: (c) Application software

Application software is built to help end-users perform specific tasks — writing documents, browsing the web, editing photos — as opposed to system software, which manages the computer itself.

✅ Answer: (c) Web browser

A web browser is application software — a program end-users interact with directly to accomplish a task (browsing websites). The other three are all system software.

✅ Answer: (d) Accessing and displaying web pages

A web browser exists to let users access and display web pages — fetching content from the internet and rendering it on screen.

✅ Answer: (d) Productivity software

Tools built to help create documents, spreadsheets, and presentations fall under productivity software — a specific sub-category of application software focused on everyday office tasks.

✅ Answer: (c) Antivirus software

Antivirus software is a utility program specifically designed to detect, block, and remove viruses and malware, keeping the system secure.

✅ Answer: (a) Creating documents, spreadsheets, and presentations

Productivity software exists to help users with everyday office work — creating documents, spreadsheets, and presentations — rather than managing the system or translating code.

✅ Answer: (b) Microsoft Office

Microsoft Office (Word, Excel, PowerPoint) is the classic example of productivity software. Photoshop and Illustrator are graphics/multimedia software, and VLC is media-player software.

✅ Answer: (c) Multimedia software

Multimedia software covers tools built for working with audio, video, and graphics — including video editing and post-production programs.

✅ Answer: (c) Storing and organizing data

Database software exists specifically for storing and organising data in a structured way so it can be efficiently retrieved, updated, and managed.

✅ Answer: (c) Entertainment software

Video games and similar apps built purely for leisure fall under entertainment software — a category of application software focused on fun rather than productivity.

✅ Answer: (c) Call of Duty

Call of Duty is a video game — pure entertainment software. Photoshop is multimedia/graphics software, Excel is productivity software, and Chrome is a web browser.
