Operating System — Part 2 MCQs with Explanations

You may have heard that Macintosh OSX is just Linux with a prettier interface. That's not actually true. But OSX is built in part on an open source UNIX derivative called FreeBSD. It was built atop UNIX, the operating system originally created over 30 years ago by researchers at AT&T's Bell Labs.

The Start button was first introduced with the release of Microsoft Windows 95 and has been featured in all releases of Windows since. The Start button allows users to access their run applications, device setting, turn off the system, computer programs or configure Microsoft Windows easily by accessing the Start Menu.

The correct answer is Option D: All of above . Each of the provided statements is true for unconditional disk formatting. Unconditional disk formatting, also known as a low-level format or full format, completely erases data on a disk by writing over every sector with zeroes or blank spaces. This process ensures that all data is removed from the disk, making it unrecoverable. Details for each option: Option A: Destroys every byte of data on a disk by overwriting it with blank spaces is true because unconditional disk formatting writes zeroes or blank data to every sector of the disk, effectively erasing all existing data. Option B: Do not check/scan surface after format is true as well because an unconditional format does not perform a surface scan to check for bad sectors; it only writes over the data. Option C: Transfer system files after format is true in the sense that after a full format, the operating system can be reinstalled or system files can be transferred to the disk as part of the installation process. Since all the options are true for unconditional disk formatting, Option D is the correct choice.

In your document, click where you want to paste the item. Do one of the following in the Clipboard: Click the down arrow next to the item you want to paste, and click Paste. To paste everything in the Clipboard to the selected area in your document, click Paste All.

A radio button or option button is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options.

The Banker algorithm, sometimes referred to as the detection algorithm, is a resource allocation and deadlock avoidance algorithm developed by Edsger Dijkstra that tests for safety by simulating the allocation of predetermined maximum possible amounts of all resources, and then makes an "s-state" check to test for possible deadlock conditions for all other pending activities, before deciding whether allocation should be allowed to continue.

An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it.

Print Management is a snap-in in Microsoft Management Console (MMC) that enables you to install, view, and manage all of the printers in your organization from any computer running Windows Server. Print Management provides up-to-the-minute details about the status of printers and print servers on the network.

A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time applications that process data as it comes in, typically without buffer delays. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter increments of time. A real time system is a time bound system which has well defined fixed time constraints.

Any amount of RAM can be allocated to virtual memory. The setting for the amount of hard drive space to allocate to virtual memory can be manually changed. This temporary storage is called the swap file (or page file). Virtual memory is physical space on the hard drive.

The essential difference between an operating system like Linux and one like Windows is that. Windows can run with an Intel processor, whereas Linux cannot. Linux is proprietary, whereas Windows is not.

The time taken by the dispatcher to stop one process and start another. The amount of time taken by the dispatcher to pause one process. and start another is called dispatch latency. The process of saving the state of a previously running process or thread. and loading the initial or previously saved state of a new process by the dispatcher. Dispatch latency is a time value.

An interrupt that occurs when a program requests data that is not currently in real memory. The interrupt triggers the operating system to fetch the data from a virtual memory and load it into RAM. An invalid page fault or page fault error occurs when the operating system cannot find the data in virtual memory.

All the files inside the directory and inside subdirectory are moved in that location.

A computer's basic input/output system (BIOS) is a program that's stored in nonvolatile memory such as read-only memory (ROM) or flash memory, making it firmware. The BIOS (sometimes called ROM BIOS) is always the first program that executes when a computer is powered up.

The ScanDisk utility begins to run. The video card and video memory are tested. The BIOS identification process occurs.

The maximum size of a write file is limited to the amount of memory in your computer. Charles Babbage originated the concept of a programmable computer. In computers, a memory unit is used for the storage of data. Memory is mainly classified into Primary memory (RAM and ROM) and Secondary memory (hard drive, CD, etc.).

A Combo Box displays a text box combined with a List Box, which enables the user to select items from the list or enter a new value. The Dropdown Style property specifies whether the list is always displayed or whether the list is displayed in a drop-down.

In computing, the Trash (also known as the Recycle Bin in Windows and by other names in other operating systems ) is temporary storage for files that have been deleted in a file manager by the user, but not yet permanently erased from the file system. Typically, a recycle bin is presented as a special file directory to the user (whether or not it is actually a single directory depends on the implementation), allowing the user to browse deleted files, undelete those that were deleted by mistake, or delete them permanently (either one by one, or by the "Empty Trash" function).

The taskbar is an element of an operating system located at the bottom of the screen. It allows you to locate and launch programs through Start and the Start menu or view any program that's currently open.

The system tray is a notification area on the operating system taskbar. It contains icons that provide users with easy access to system functions such as email, printer, network connections and volume control. The icons also indicate the statuses of the processes running on the computer.

Windows XP Media Center Edition (MCE) is a version of the Windows XP operating system which was the first version of Windows to include Windows Media Center, designed to serve as a home-entertainment hub.

An operating system version designed for use with a tablet PC is Microsoft Windows XP Tablet PC edition. A tablet PC is a portable PC that is a hybrid between a personal digital assistant (PDA) and notebook PC. Equipped with a touch screen interface, a tablet PC usually has a software application used to run a virtual keyboard. However, many tablet PCs support external keyboards.

When we turn on our computer installed operating system will start working. It ensures the co-ordination of other stored programs with system's hardware components. To enable operating system a Process is done which is called "Booting".

The System menu contains commands associated with the My Computer window. The Android System Settings menu allows you to control most aspects of your device everything from establishing a new Wi-Fi or Bluetooth connection, to installing a third-party onscreen keyboard, to adjusting system sounds and screen brightness.

Operating system is the layer of a computer system between the hardware and the user program. For the most part, the IT industry largely focuses on the top five OSs, including Apple Mac OS, Microsoft Windows, Google's Android OS, Linux Operating System, and Apple I OS.

When power is turned on, POST (Power-On Self-Test) is the diagnostic testing sequence that a computer's basic input/output system (or "starting program") runs to determine if the computer keyboard, random access memory, disk drives, and other hardware are working correctly.

The operating system is the most common type of system software. System software is computer software designed to provide a platform to other software. Examples of system software include operating systems, computational science software, game engines, industrial automation, and software as a service application.

External commands are predefined commands for end users. They are operating-system independent and are protected by authorizations, so that normal end users can schedule only those commands that the system administrator permits them to.

After finding the power button, press the button to turn off the monitor. Sometimes, you may need to press and hold the power button for 2 or 3 seconds to power off the monitor. Some monitor power buttons may also only require your finger touch and not push in on the button.

Dr. Watson is a diagnostic tool that gathers information about your computer when a problem occurs with a program. The information gathered by Dr. Watson is called a snapshot. The snapshot includes information that: Identifies the program that has a problem.

A bar that informs you the available options in your computer, opened applications, background running applications and can be used to switch between applications quickly is Task bar.

Answer: Taskbar is used to launch an application through the start menu. It displays all the opened applications and files. It is used to set taskbar and desktop properties.
