Which one of these is an operating system?

Sony
Hp
Macintosh
Dell
Toshiba

Correct Answer

A. Macintosh

Explanation

Macintosh is an operating system. It is developed by Apple Inc. and is the operating system used on Apple Macintosh computers. It provides the user interface and manages the hardware and software resources of the computer. Sony, HP, Dell, and Toshiba are not operating systems; they are brands of computer hardware.

Which of the following will determine your choice of systems software for your computer ? .

Is the applications software you want to use compatible with it
Is it expensive ?
Is it compatible with your hardware ?
Both 1 and 3

Correct Answer

A. Both 1 and 3

Explanation

The choice of systems software for a computer is determined by two factors: compatibility with the desired applications software and compatibility with the hardware. If the applications software is not compatible with the systems software, it cannot be used effectively. Similarly, if the systems software is not compatible with the hardware, it may not function properly. Therefore, both factors, 1 and 3, need to be considered when making a choice of systems software.

What is a shell ?

It is a hardware component
It is a command interpreter
It is a part in compiler
It is a tool in CPU scheduling

Correct Answer

A. It is a command interpreter

Explanation

A shell is a command interpreter that allows users to interact with an operating system by executing commands. It provides a user-friendly interface for users to run programs, manage files, and perform various tasks on a computer. The shell interprets the commands entered by the user and translates them into instructions that the operating system can understand and execute.

Virtual memory is __________.

An extremely large main memory
An extremely large secondary memory
An illusion of extremely large main memory
A type of memory used in super computers

Correct Answer

A. An illusion of extremely large main memory

Explanation

Virtual memory is an illusion of extremely large main memory. It is a technique that allows a computer to use more memory than is physically available by using disk space as an extension of the main memory. This illusion is created by the operating system, which manages the mapping of virtual addresses to physical addresses and handles the movement of data between main memory and disk storage. By using virtual memory, programs can access a larger address space, improving overall system performance and allowing for the execution of larger and more complex applications.

The Hardware mechanism that enables a device to notify the CPU is called __________.

Polling
Interrupt
System Call
None of the above

Correct Answer

A. Interrupt

Explanation

Interrupt is the correct answer because an interrupt is a hardware mechanism that allows a device to interrupt the normal flow of the CPU and notify it that it requires attention. When an interrupt occurs, the CPU stops its current execution and jumps to a specific interrupt handler routine to handle the request from the device. This mechanism allows devices to asynchronously communicate with the CPU and ensures efficient and timely handling of various events and tasks.

___________ begins at the root and follows a path down to the specified file

Relative path name
Absolute path name
Standalone name
All of the above

Correct Answer

A. Absolute path name

Explanation

An absolute path name begins at the root directory and follows a path down to the specified file. It provides the complete and exact location of the file or directory, starting from the root directory and including all intermediate directories. This allows for precise navigation and identification of the file or directory, regardless of the current working directory. Relative path names, on the other hand, are specified relative to the current working directory, while standalone names do not provide any path information and assume the file or directory is in the current working directory. Therefore, the correct answer is absolute path name.

Virtual Memory is commonly implemented by __________.

Segmentation
Swapping
Demand Paging
None of the above

Correct Answer

A. Demand Paging

Explanation

Virtual memory is commonly implemented by demand paging. Demand paging is a memory management technique where data is loaded into memory only when it is needed, rather than loading the entire program into memory at once. This allows for efficient memory utilization and allows programs to run even if the physical memory is limited. With demand paging, the operating system can swap pages of data between the physical memory and the disk, bringing in only the required pages when they are needed. This helps to optimize the use of memory resources and improve overall system performance.

Consider the two statements.(A) A network operating system, the users access remote resources in the same manner as local resource.(B) In a distributed operating system, the user can access remote resources either by logging into the appropriate remote machine or transferring data from the remote machine to their own machine. Which of the statement is true?

A true, b false
B true,a false
Both a and b false
Both a and b true

Correct Answer

A. Both a and b false

Explanation

The given answer states that both statements A and B are false. This means that neither in a network operating system nor in a distributed operating system, the users access remote resources in the same manner as local resources. Additionally, in a distributed operating system, the user cannot access remote resources by logging into the appropriate remote machine or transferring data from the remote machine to their own machine.
