UGC NET Questions (Paper – 1)

The operating system mediates interactions between users and hardware by providing a user-friendly environment and standardised services. Users issue commands via graphical or command interfaces, and the OS translates these into low-level hardware instructions. It shields users from the complexity of device management and memory handling. Hence it functions as an interface between the user and the hardware.

Option A:
Option A, a compiler, translates high-level programming code into machine code but does not manage overall user interaction with the system. It is a development tool that itself runs under the operating system. Therefore it cannot be regarded as the primary interface.

Option B:
Option B, network protocol, specifies rules for communication between networked devices. Protocols operate at communication layers and are implemented within or above the OS, but they are not themselves the general interface for all user–hardware interaction.

Option C:
Option C, firewall, is a security component controlling network traffic and is often implemented as part of system software. However, it plays a protective role rather than providing a broad user interface to all hardware resources.

Option D:
Option D is correct because the OS presents menus, windows and commands that allow users to control programs and hardware without dealing directly with low-level details. This intermediary role is accurately summarised as acting as an interface.

System software is designed to control and coordinate the hardware components of a computer. It provides a platform on which application software can run and offers generic services like file management, memory management and device control. Operating systems, utility programs and device management modules fall under this category. Therefore the description in the stem correctly points to system software.

Option A:
Option A, application software, is written to perform specific user tasks such as word processing or spreadsheet analysis. It relies on lower-level services provided by system software and does not itself generally manage hardware resources. Hence it does not satisfy the description.

Option B:
Option B, firmware, is software embedded into hardware devices and stored in non-volatile memory. While it helps control specific equipment, it does not usually provide broad services to other programs running on a general-purpose computer. Thus it is too narrow to fit the stem.

Option C:
Option C is correct because system software sits between the hardware and user applications, managing resources and offering standard services. It includes the operating system and core utilities that ensure the whole system functions reliably. This role precisely matches the statement in the question.

Option D:
Option D, a device driver, is a specialised program that allows the operating system to communicate with a specific hardware device. It is typically considered a component of system software rather than the overarching category itself. Therefore it is not the best completion for the blank.

Statements A, B and C correctly capture the fundamental relationship between hardware and software in ICT. Hardware is indeed the tangible part of the computer system, while system software like operating systems manages these resources and supports application software. Application software performs specific user tasks such as document creation or computations. Statement D is incorrect because hardware and software are interdependent and must interact for any ICT operation, so the correct combination of true statements is A, B and C only.

Option A:
Option A is incorrect because it recognises only statement A as correct and treats the others as incorrect by omission. While statement A is true, statements B and C are also true descriptions of system and application software. Leaving out B and C makes this option an incomplete and therefore wrong representation of the correct set of statements.

Option B:
Option B is incorrect because it includes only statements A and B. Although both A and B are true, statement C is also a correct description of application software performing user-specific tasks. By failing to include statement C among the correct statements, this option cannot be accepted.

Option C:
Option C is correct because it groups together all and only the true statements, namely A, B and C. These three statements collectively describe how hardware, system software and application software work together in an ICT system. They show the layered structure where hardware is controlled by system software and used by application software to fulfil user needs, while correctly excluding the false statement D.

Option D:
Option D is incorrect because it adds statement D to the otherwise correct group of A, B and C. Statement D is false, as hardware and software must interact closely within any ICT system for processing to occur. Including a false statement alongside true ones invalidates this combination as the correct answer.

System software, such as operating systems, coordinates all hardware operations and creates an environment where other programs can run. Application software includes tools like word processors, browsers and statistical packages that address particular user needs. The main difference lies in their role and level of interaction with hardware. This option expresses that distinction clearly.

Option A:
This option correctly shows that applications sit above the system layer and rely on it. It also shows that system software is more fundamental to the functioning of the computer. Such classification is frequently tested in UGC NET ICT questions.

Option B:
Application software does not directly manage CPU scheduling, memory allocation or device control. Assigning these functions to applications confuses their purpose and exaggerates their role.

Option C:
Pricing of software depends on licensing models and business decisions and is not an inherent characteristic separating application and system software. Both can be free or paid.

Option D:
Application software normally depends on system software to execute. Without an operating system, most applications cannot access hardware, so the claim that they can work without it is incorrect.

An operating system is a core system software that controls and coordinates the use of hardware among various application programs. It allocates processor time, manages memory, handles input-output operations and maintains file systems. It also provides a user interface through which users interact with the computer. Therefore, the description in this option accurately summarises the OS role.

Option A:
This option treats the operating system as just another application like a word processor or presentation tool. In reality, applications run on top of the OS and depend on it for hardware access. Thus, this description confuses application software with system software.

Option B:
This option misclassifies the operating system as a physical input device, such as a keyboard or mouse. The OS is not a tangible hardware unit but a collection of programs. Hence, the option is conceptually incorrect.

Option C:
This option confuses operating systems with communication protocols like SMTP or IMAP used for email transfer. Protocols are standards for data communication, whereas the OS is responsible for managing the overall functioning of the computer system.

Option D:

Statements A, B and D accurately describe key responsibilities of an operating system, whereas C is false. The operating system allocates and coordinates hardware resources, provides user interfaces and manages files in storage. These functions are present on desktops, laptops and mobile devices alike. Statement C wrongly restricts operating systems to mobiles, ignoring widely used desktop and server operating systems. Thus, the correct set is A, B and D only.

Option A:
Option A is correct because it collects all the true statements regarding OS roles and correctly excludes C. It shows that operating systems are central to controlling hardware, providing interaction and organising files across different computing platforms.

Option B:
Option B is incorrect because it lists A and D only, leaving out B. While resource and file management are crucial, the user interface is also a primary function of modern operating systems and should not be omitted.

Option C:
Option C is incorrect because it treats B, C and D as correct, thereby accepting C. Since C contradicts the existence of desktop OS like Windows, Linux and macOS, this option cannot be considered accurate.

Option D:
Option D is incorrect because it assumes all four statements are correct and so accepts C. Including a clearly false claim about where operating systems are used invalidates the entire combination.

Statements A, B and D are correct descriptions of hardware, system software and firmware, while statement C is clearly incorrect. Hardware consists of tangible components, system software covers operating systems and drivers, and firmware is stored permanently in device memory. Application software does not need to be soldered onto a motherboard; it is stored on storage media and loaded into memory for execution. Therefore, the combination that includes A, B and D but excludes C is the correct answer.

Option A:
Option A is incomplete because it includes only A and B and omits D. While A and B are true, firmware as described in D is also an important software category. Since one true statement is missing, this option does not capture the full set of correct statements.

Option B:
Option B includes B and D but leaves out A, even though A accurately defines hardware. Although system software and firmware are correctly identified, this option fails to mention that hardware refers to physical components and so is not complete.

Option C:
Option C is correct because it groups A, B and D, the three true statements, and excludes the false idea in C that software must be physically soldered. It gives a coherent picture of hardware, system software and firmware within ICT systems.

Option D:
Option D is incorrect because it treats all four statements as correct, thereby accepting C. Including the absurd notion that application software must be soldered onto the motherboard makes this option conceptually wrong.

Statements A, B and D correctly describe core functions of an operating system, while statement C is false. The operating system does manage memory, processes and I/O, it offers a user interface, and it handles files and directories. It is not a specialised text-editing application, so describing it as such is misleading. Thus, the combination that includes A, B and D but excludes C is the only correct answer.

Option A:
Option A is incorrect because it includes only statement A and ignores B and D. Although statement A is true, the question asks for all correct statements, and both B and D also describe essential operating system functions. Leaving these out makes the option incomplete.

Option B:
Option B is incorrect because it combines A and B but omits D. Statements A and B are indeed correct, but D is also accurate in attributing file management to the operating system. Since one true statement is missing, this option does not provide the full set of correct statements.

Option C:
Option C is correct because it brings together A, B and D, which are all true. It excludes statement C, which wrongly claims that an operating system is just an application for text editing. By including all and only the correct statements, this option matches the conceptual role of operating systems in ICT.

Option D:
Option D is incorrect because it includes statement C along with B and D. While B and D are true, C misrepresents the nature of an operating system. Including a false statement means the combination cannot be considered fully correct.

An operating system coordinates activities of hardware components, allocates resources to programs and offers services like file management and user interfaces. It enables application software to run without needing to control hardware directly. Because of these central responsibilities, it is often described as the backbone of the computer system. Therefore, the term that completes the statement is operating system.

Option A:
Option A, compiler, translates high level language programs into machine code but does not manage hardware or provide a general user interface.

Option B:
Option B is correct because operating systems such as Windows, Linux and macOS are specifically defined as system software that manage resources and serve as intermediaries between user and hardware.

Option C:
Option C, interpreter, executes source code line by line but again is an application tool rather than the overarching management software.

Option D:
Option D, device driver, is specialised software that allows the OS to communicate with particular hardware devices, not the full management layer itself.

The operating system is the core system software that coordinates interactions between hardware and application programs. It handles tasks such as memory allocation, process scheduling, file management and device control. Without an operating system, most applications cannot run effectively. Hence, the managing software described in the stem is the operating system.

Option A:
Option A is correct because definitions of operating systems consistently emphasise resource management and service provision for applications. Examples include Windows, Linux and macOS, all of which perform the roles listed in the question.

Option B:
Option B, word processor, is a specific application for creating and editing documents and does not manage hardware resources. It itself depends on the operating system to function.

Option C:
Option C, browser extension, is an add-on module that enhances browser capabilities and cannot perform system-wide resource management.

Option D:
Option D, device driver, is a specialised program that allows the operating system to communicate with a specific hardware component, but it is not the overarching manager of all resources.

Statements A, B and C correctly describe major categories of computer software, while statement D is incorrect. System software does manage hardware and provide a base for other programs, application software does handle specific user tasks, and utilities support maintenance and optimisation. Firmware, however, is typically stored in non-volatile memory on hardware devices and not always on removable media. Therefore, the combination that includes A, B and C but excludes D is the only correct answer.

Option A:
Option A includes statements A, B and C and omits D, so it contains exactly the true statements. It recognises the distinct roles of system, application and utility software in a computer system. Because it does not include the false claim about firmware storage, this option accurately represents the set of correct statements.

Option B:
Option B combines A and D only, which makes the set both incomplete and partly wrong. While statement A is true, statement D wrongly suggests that firmware is always stored only on removable media. It also ignores statements B and C, which are correct, so this option cannot represent the full set of correct statements.

Option C:
Option C groups B, C and D together, mixing true and false information. Statements B and C are correct descriptions of application and utility software, but statement D is incorrect about firmware. By excluding statement A, which is also true, and including a false statement, this option cannot be accepted as correct.

Option D:
Option D includes all four statements, so it brings in the incorrect statement D along with the true ones. Because a correct answer must contain only true statements, including D makes this option invalid. Even though A, B and C are correct, the presence of the false statement prevents this combination from being the right answer.
