Correct Option: A

…….transforms one interface into another interface

  1. Program

  2. Software

  3. Data

  4. None


Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of interface in the context of programming.

An interface is a programming construct that defines a contract or a set of rules that a class must adhere to. It specifies a list of methods that a class must implement. By implementing an interface, a class can provide a certain behavior or functionality.

In this context, the correct answer is B) Software. Software can transform one interface into another interface by implementing the required methods and adhering to the contract defined by the interface. This allows software components to communicate and interact with each other through a common interface, enabling interoperability and modularity.

Option A) Program is incorrect because a program is a set of instructions that perform a specific task or solve a problem. It does not directly transform interfaces.

Option C) Data is incorrect because data refers to the raw facts and statistics that are processed and manipulated by software programs. While data can be transformed or processed, it does not directly transform interfaces.

Option D) None is incorrect because software is capable of transforming one interface into another interface, as explained above.

…..system is built directly on the hardware

  1. Environment

  2. System

  3. Operating

  4. None


Correct Option: C

Multiprogramming system

  1. Are easier to develop than single programming system

  2. Execute each job faster

  3. Execute more jobs in the same time period

  4. Are used only one large mainframe computers


Correct Option: C

…is the first program run on a computer when the computer boots up

  1. System software

  2. Operating system

  3. System operations

  4. None


Correct Option: B

AI Explanation

To answer this question, you need to understand the sequence of events that occur when a computer boots up.

Option A) System software - This option is incorrect because system software refers to a collection of software programs that manage and control the computer's hardware resources. System software is not the first program run on a computer during boot-up.

Option B) Operating system - This option is correct because the operating system is the first program that is loaded into the computer's memory when the computer boots up. The operating system controls the computer's hardware and provides a platform for other software programs to run.

Option C) System operations - This option is incorrect because "system operations" is not a commonly used term and does not accurately describe the first program run on a computer during boot-up.

Option D) None - This option is incorrect because there is always a program that runs first when a computer boots up, and that program is the operating system.

The correct answer is B) Operating system. This option is correct because the operating system is the first program run on a computer when it boots up.

…..interface consists of things like program counter, registers, interrupts and terminals

  1. Hardware

  2. Software

  3. Data

  4. None


Correct Option: A

AI Explanation

To answer this question, you need to understand the concept of computer architecture and the different components involved in it.

The correct answer is A) Hardware.

Option A) Hardware - This option is correct because the components mentioned in the question, such as the program counter, registers, interrupts, and terminals, are all physical components of a computer system. These components are part of the hardware and are responsible for executing instructions and managing the flow of data within the computer.

Option B) Software - This option is incorrect because software refers to the programs and instructions that run on the hardware. While software can interact with and make use of the hardware components mentioned, it is not the correct answer in this case.

Option C) Data - This option is incorrect because data refers to the information processed and stored by the computer system. While data is an important aspect of computing, it does not directly relate to the specific components mentioned in the question.

Option D) None - This option is incorrect because the components mentioned in the question are indeed part of the computer system, specifically the hardware components.

Therefore, the correct answer is A) Hardware. This option is correct because the components mentioned in the question, such as the program counter, registers, interrupts, and terminals, are all physical components of a computer system.

….share characteristics with both hardware and software

  1. Operating System

  2. Hardware

  3. Data

  4. Software


Correct Option: A

….is used in operating system to separate mechanism from policy

  1. Single level implementation

  2. Two level implementation

  3. Multi level implementation

  4. None


Correct Option: B
  1. Virtual space

  2. Virtual computers

  3. Virtual device

  4. None


Correct Option: B

Swapping

  1. Works best with many small partitions

  2. Allows many programs to use memory simultaneously

  3. Allows each program in turn to use the memory

  4. Does not work with overlaying


Correct Option: C

Which of the following operating does not implement multitasking truly?

  1. Windows 98

  2. Windows XP

  3. Windows NT

  4. MS DOS


Correct Option: D

Where do you find user.dat?

  1. C:\windows

  2. C:\windows\system32

  3. C:\windows\system

  4. C:\


Correct Option: A

AI Explanation

To answer this question, you need to have knowledge about the location of the "user.dat" file.

Option A) C:\windows - This option is the correct answer. The "user.dat" file is typically found in the C:\windows directory.

Option B) C:\windows\system32 - This option is incorrect because the "user.dat" file is not usually located in the system32 subdirectory.

Option C) C:\windows\system - This option is incorrect because the "user.dat" file is not typically found in the system subdirectory.

Option D) C:\ - This option is incorrect because the "user.dat" file is not usually located in the root directory (C:).

The correct answer is A) C:\windows. This option is correct because the "user.dat" file is typically found in the C:\windows directory.

MSD.exe does not have information on:

  1. Cache

  2. Video

  3. Operating System

  4. Com or port


Correct Option: A

AI Explanation

To answer this question, we need to understand what MSD.exe is and what type of information it provides.

MSD.exe is a command-line tool in Windows that stands for Microsoft System Diagnostics. It provides detailed information about the hardware and software configuration of a computer system. When you run MSD.exe, it generates a report that includes information about various system components.

Let's go through each option to understand why it is correct or incorrect:

Option A) Cache - This option is correct because MSD.exe does not provide information specifically about the cache. The cache is a hardware component that temporarily stores data to improve system performance. While MSD.exe provides information about other hardware components like the CPU, memory, and storage, it does not include details about the cache.

Option B) Video - This option is incorrect because MSD.exe does provide information about the video or graphics card. The report generated by MSD.exe includes details about the installed video card, display resolution, and other video-related information.

Option C) Operating System - This option is incorrect because MSD.exe does provide information about the operating system. The report generated by MSD.exe includes details about the installed version of Windows, system files, and other operating system-related information.

Option D) COM or Port - This option is incorrect because MSD.exe does provide information about COM ports. The report generated by MSD.exe includes details about the available COM ports on the system and their configurations.

Therefore, the correct answer is A) Cache. MSD.exe does not have information on the cache.
