1.
___runs on computer hardware and serve as platform for other softwares to run on
Correct Answer
A. Operating System
Explanation
The operating system runs on computer hardware and serves as a platform for other software to run on. It manages the computer's resources, such as memory and processing power, and provides a user interface for interacting with the computer. Application software refers to specific programs that perform tasks for the user, while system software includes the operating system and other essential programs that support the computer's operation. Therefore, the correct answer is the operating system.
2.
___ is the layer of a computer system between the hardware and the user program
Correct Answer
B. Operating system
Explanation
The operating system is the layer of a computer system between the hardware and the user program. It manages the computer's resources, such as the processor, memory, and input/output devices, and provides a platform for running applications. The operating system acts as an intermediary, allowing the user program to interact with the hardware without directly accessing it. It provides services and utilities that enable the user to perform tasks and manage files and processes. Therefore, the operating system is the correct answer in this case.
3.
The primary purpose of an operating system is ____
Correct Answer
A. To make the most efficient use of the computer hardware
Explanation
The primary purpose of an operating system (OS) is to manage and coordinate the hardware and software resources of a computer system. This includes tasks such as managing memory, processing tasks, handling input and output operations, and ensuring efficient and secure use of the hardware. While making computers easier to use and allowing people to use computers are important secondary goals, the main function of an OS is to optimize the use of the computer hardware.
4.
____ transforms one interface into another interface
Correct Answer
B. Software
Explanation
The term "transform" implies a change or conversion from one form to another. In this context, "software" is the only option that can be transformed or converted into another interface. Programs and data are components of software, but they themselves cannot be transformed into interfaces. Therefore, the correct answer is "Software."
5.
_____ system is built directly on the hardware
Correct Answer
C. Operating
Explanation
An operating system is a software that directly interacts with the hardware of a computer system. It manages the computer's resources, such as memory, processor, and input/output devices, and provides a platform for other software applications to run on. It controls the execution of programs and allows users to interact with the computer. Therefore, an operating system is built directly on the hardware to facilitate the functioning of the entire system.
6.
Multiprogramming systems
Correct Answer
C. Execute more jobs in the same time period
Explanation
Multiprogramming systems are designed to efficiently utilize the available resources by allowing multiple jobs to be executed simultaneously. This means that multiple jobs can be processed at the same time, resulting in the ability to execute more jobs in the same time period compared to single programming systems. This increases the overall throughput and productivity of the system.
7.
_______ is the first program run on a computer when the computer boots up
Correct Answer
B. Operating system
Explanation
The operating system is the first program run on a computer when it boots up. It is responsible for managing all the hardware and software resources of the computer, including memory, processors, and input/output devices. The operating system also provides a user interface and allows users to interact with the computer. Without an operating system, the computer would not be able to perform any tasks or run any other programs.
8.
________ interface consists of things like program counter, registers, interrupts and terminals
Correct Answer
A. Hardware
Explanation
The correct answer is Hardware. The interface described in the question consists of physical components such as the program counter, registers, interrupts, and terminals, which are all part of the hardware of a computer system. Software refers to the programs and instructions that run on the hardware, while data refers to the information processed by the computer.
9.
______ shares characteristics with both hardware and software
Correct Answer
A. Operating system
Explanation
An operating system shares characteristics with both hardware and software. On one hand, it has hardware-like functions such as managing computer resources, providing an interface for communication between hardware and software, and controlling input/output devices. On the other hand, it is also software that can be installed, upgraded, and customized. It provides a platform for running applications and manages software resources. Therefore, an operating system is the correct answer as it encompasses both hardware and software characteristics.
10.
____ is used in operating system to separate mechanism from policy
Correct Answer
B. Two level implementation
Explanation
Two level implementation is used in operating systems to separate mechanism from policy. In this approach, the operating system is divided into two levels: the lower level, which consists of the mechanism that performs the basic functions such as process management, memory management, and device management, and the higher level, which consists of the policy that determines how these functions are performed. This separation allows for greater flexibility and customization, as different policies can be implemented without changing the underlying mechanisms.
