Computer Fundamentals and System Concepts Questions

Multiple choice technology operating systems

What is the Registry used for?

  1. It stores information about all of the software and hardware on the system.

  2. It stores hardware information only

  3. It stores software information only

  4. It stores system information only
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Windows Registry stores configuration data for ALL system components: installed software, hardware devices, user preferences, and system settings. It's a hierarchical database that Windows and applications query. Options B, C, and D are incorrect because the Registry doesn't discriminate - it stores everything.

Multiple choice technology

The British Colossus computer was used to do what?

  1. Add

  2. Break German wartime codes

  3. Design war vehicles

  4. Store nonsense information
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Colossus computer was a British code-breaking machine used during World War II to decrypt German Lorenz cipher messages. It was the world's first programmable electronic digital computer and played a crucial role in Allied intelligence efforts.

Multiple choice technology programming languages

You can launch Windows programs that have a GUI, such as Notepad and Calculator, within Windows PowerShell.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Windows PowerShell is a command-line shell designed for scripting and administration. While you can launch GUI applications from PowerShell using commands like 'notepad.exe', PowerShell itself is a text-based console environment and does not host GUI applications within its window.

Multiple choice technology programming languages

PowerShell is often referred to as what?

  1. An object oriented shell built on the .NET Framework

  2. A clam shell

  3. A band shell

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To answer this question, the user must be familiar with the basic features and functionalities of PowerShell.

The correct answer is:

A. An object-oriented shell built on the .NET Framework

Option A is correct because PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and associated scripting language. It is built on the .NET Framework and is object-oriented, allowing users to interact with various system objects through commands and scripts.

Option B is incorrect because "clam shell" is not a common term used to describe PowerShell. A "clam shell" typically refers to a type of laptop design where the screen and keyboard fold together to form a clam-like shape.

Option C is incorrect because a "band shell" is a type of outdoor performance venue and has nothing to do with PowerShell.

Option D is incorrect because only option A is correct. Options B and C are incorrect.

Therefore, the answer is:

The Answer is: A

What is PowerShell?

  1. A fabulous dessert topping

  2. A terrific floor wax

  3. The future of Windows automation and administration

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

PowerShell is indeed Microsoft's primary automation and management framework for Windows. It has become the future of Windows administration, replacing older tools like VBScript and batch files. The humorous options A and B reference a classic Saturday Night Live commercial parody, and are clearly wrong.

Multiple choice technology architecture

What is a Kernel?

  1. acts as an interface between the user and the kernel.

  2. is the hub of the operating system.

  3. minimal operating system that performs only the essential functions of an operating system.

  4. None of the above.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The kernel is the core component of an operating system that manages system resources and provides essential services. It acts as the central hub between hardware and software, handling process management, memory management, and I/O operations.

Multiple choice technology

Agents are

  1. Standalone programs that performs a specific task

  2. Agents can also be set to run unattended on the server, either on a schedule or when certain events occur.

  3. Both

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Agents in software systems are autonomous programs designed to perform specific tasks. They can operate independently as standalone programs and are also capable of unattended execution on servers. This unattended operation can be scheduled (time-based triggers) or event-driven (triggered by specific conditions or events occurring in the system).

Multiple choice technology operating systems

What is the first process that comes into existence whenever system is booted?

  1. init

  2. shell

  3. kernel

  4. login
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

During the system boot sequence, the kernel is loaded into memory first and acts as the initial entity running on the system. Although init is the first user-space process (PID 1), Unix MCQ contexts conventionally consider the kernel as the first system process/entity that comes into existence.

Processor Specification

  1. ARM processor

  2. RISC processor

  3. Core 2 Quad Processor

  4. Dual core processor
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The 5 PEN PC concept specified a dual-core processor configuration. While ARM and RISC processors are common in mobile devices, the original concept specifically mentioned dual-core architecture. Core 2 Quad is a desktop processor that would be too power-hungry for a pen-sized device, and ARM/RISC are processor architectures rather than specific core configurations.

Multiple choice technology

Processor Specification

  1. ARM processor

  2. RISC processor

  3. Core 2 Quad Processor

  4. Dual core processor
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The 5 PEN PC architecture specifies a dual-core processor for its computing unit. This balances performance requirements with power efficiency needed for a pen form factor. ARM and RISC refer to processor architectures rather than specific specifications, while Core 2 Quad is too power-hungry for this application.

Multiple choice technology testing

Batch scripts are generally used for

  1. To execute a set of statements in one go

  2. To do file management

  3. To make registry changes

  4. All the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Batch scripts are versatile automation tools that can execute multiple commands sequentially, perform file management operations (copy, move, delete), and modify the Windows registry using reg.exe commands. This makes them widely used for system administration and task automation.

Multiple choice technology

____________ is the process of translating a task into a series of commands that a computer will use to perform that task.

  1. Project Design

  2. Installation

  3. System Analysis

  4. Programming
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Programming is the process of converting a task or problem into a specific set of instructions that a computer can execute. It involves translating human-readable logic into machine-executable code using a programming language. Project Design involves planning, Installation is deployment, and System Analysis is understanding requirements.

Multiple choice technology

The problem statement should include all of the following EXCEPT:

  1. Input

  2. Output

  3. Processing

  4. Storage
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A problem statement should specify Input (what data enters the system), Output (what results the system produces), and Processing (how inputs are transformed to outputs). Storage refers to where data is kept, which is an implementation detail rather than part of the fundamental problem definition. The question asks which is NOT required.
