An operating system is considered as system software because it is responsible for managing and controlling the computer's hardware and software resources. It provides a platform for other software applications to run on the computer and acts as an intermediary between the user and the hardware. The operating system performs essential tasks like memory management, process scheduling, file management, and device management. Therefore, it is classified as system software rather than application software, hardware component, or I/O device.

The Central Processing Unit (CPU) is responsible for processing data in a computer. It is often referred to as the "brains" of the computer because it performs the majority of the calculations and operations necessary for the computer to function. The CPU interprets and executes instructions from the computer's memory, performs arithmetic and logical operations, and controls the flow of data between different parts of the computer. In short, the CPU is the core component that carries out the actual processing of data in a computer system.

Word processing, spreadsheet, and photo editing are examples of application software. Application software refers to programs or software that are designed to perform specific tasks or applications for the user. These types of software are typically used for creating, editing, and managing documents, spreadsheets, and images. They are different from system software, which includes the operating system and other software that manages the computer's hardware and resources.

The question asks for examples of input devices, which are devices used to input data into a computer. A scanner, mouse, and keyboard are all examples of input devices because they allow the user to input data or commands into the computer. However, a printer is an output device because it allows the computer to produce a physical copy or printout of data. Therefore, the correct answer is "Printer" because it is not an example of an input device.

The CPU and memory are located on the motherboard. The motherboard is the main circuit board of a computer system and it houses various components, including the central processing unit (CPU) and memory modules. These components are essential for the functioning of a computer system as the CPU performs calculations and executes instructions, while the memory stores data and instructions for the CPU to access and process. Therefore, the motherboard is the correct answer as it is where the CPU and memory are located.

The operating system manages memory by allocating and deallocating memory resources to different processes. It manages the processor by scheduling and prioritizing tasks to be executed by the CPU. It also manages I/O devices by handling input and output operations between the devices and the processes. Lastly, it manages disk operations by controlling disk access and managing file systems. Therefore, the correct answer is "All of these" as the operating system is responsible for managing all these aspects.

A scanner is an example of an input device because it allows users to input physical documents or images into a computer system. It uses optical technology to convert the physical document or image into a digital format that can be stored, edited, or shared electronically. This makes it possible for users to input physical documents or images into a computer system for various purposes such as scanning documents for digital storage, scanning photos for editing or sharing, or scanning barcodes for inventory management.

The operating system is a program that manages and allocates the control of all system resources, including the processor, main memory, and I/O devices. It acts as an intermediary between the hardware and the user, providing a user-friendly interface and ensuring that all resources are utilized efficiently.

A gigabyte is approximately one billion bytes. It is a unit of digital information storage and is often used to measure the capacity of computer storage devices or the size of files. It is larger than a kilobyte, megabyte, and byte, and smaller than a terabyte.

A bit is the fundamental unit of information in computing and digital communications. It represents a binary digit, which can have two possible values: 0 or 1. Therefore, the term "bit" is short for "binary digit." This term is used to describe the smallest unit of data in a computer system, where information is stored and processed in binary form.

The PC (personal computer) and the Apple Macintosh are examples of two different platforms. A platform refers to the underlying hardware and software system that allows applications to run on a computer. In this case, the PC and the Apple Macintosh have different operating systems and architectures, making them distinct platforms.

The correct answer is "System". System software refers to the set of programs that facilitate the functioning of a computer's hardware devices and software. It includes the operating system, device drivers, and utility programs that help manage and control the computer system. System software acts as an intermediary between the hardware and the application software, ensuring smooth communication and coordination between the two.

The system unit is where the components that process data are located. This includes the motherboard, central processing unit (CPU), memory, and other internal components. The input and output devices, such as keyboards, mice, monitors, and printers, are connected to the system unit but do not directly process data. The storage component, which includes hard drives and solid-state drives, stores data but does not process it. Therefore, the correct answer is system unit.

Software is a set of computer programs used on a computer to help perform tasks. It consists of instructions that enable the computer to execute specific functions or operations. Software can be categorized into different types such as application software, system software, and programming software. It is an essential component of a computer system and is responsible for enabling users to interact with the hardware and perform various tasks efficiently.

The operating system is responsible for managing all the software and hardware resources of a computer system. It provides the necessary functionality for the computer to boot up and start running. Without an operating system, the computer would not be able to properly initialize and load the necessary software and drivers to start up. Therefore, the computer cannot boot if it does not have an operating system.

Real time software refers to software that is designed to measure, monitor, analyze, and control real-world events. It operates in real time, meaning it processes and responds to data immediately as it is received, without any noticeable delay. This type of software is commonly used in industries such as manufacturing, telecommunications, and transportation, where timely and accurate data processing is crucial for efficient operations. Real time software is different from system software, operating systems, scientific software, and business software, as it specifically focuses on real-time event processing.

An operating system is a software program that manages computer hardware and software resources and provides common services for computer programs. It acts as an intermediary between the computer hardware and the user, allowing the user to interact with the computer system. Therefore, the correct answer is "Software routines" as an operating system primarily consists of software routines that perform various tasks such as memory management, process scheduling, file management, and device control.

A distributed system is a network of autonomous computers that work together to achieve a common goal. In a distributed system, each computer operates independently and has its own memory and processing power. These computers communicate and coordinate with each other through messages to complete tasks efficiently. This allows for better performance, fault tolerance, and scalability compared to a single centralized system. Therefore, a distributed system is the correct answer for the given question.

Spooling stands for Simultaneous peripheral operation online. Spooling is a process in which data is temporarily stored in a spool, which is a designated area of memory or disk, before it is sent to an output device for processing. This allows for multiple peripheral devices, such as printers or disk drives, to be accessed simultaneously by the computer system. Spooling helps to improve efficiency and performance by allowing the computer to continue processing other tasks while the output devices are busy.

A time shared operating system allows multiple users to share the computer's resources simultaneously. This means that each user is given a small time slice to use the computer, and the operating system switches between users rapidly to give the illusion of simultaneous usage. This allows for efficient utilization of the computer's resources and enables multiple users to work on the system at the same time.

Multitasking is a logical extension of multiprocessing because it involves the concurrent execution of multiple tasks or processes on a single processor. While multiprocessing refers to the use of multiple processors to execute tasks simultaneously, multitasking allows a single processor to switch between tasks rapidly, giving the illusion of parallel execution. This is achieved through techniques such as time-sharing and context switching, where the processor allocates small time slices to each task, allowing them to make progress in a seemingly concurrent manner.

The given statement states that Apple Macs and PCs use different methods to process data and different operating systems. This implies that the correct answer must be related to the different methods used by the two systems. The other options, such as languages, CPUs, and storage devices, are not directly related to the processing of data. Therefore, the correct answer is "Methods."

A parallel system is a type of system that has more than one CPU. In a parallel system, multiple CPUs work together to execute tasks simultaneously, which can greatly increase the system's processing power and performance. This allows for faster computation and improved efficiency in handling complex tasks or large datasets.

The operating system resides in memory in all parts - the upper part, lower part, and middle part. This is because the operating system needs to be loaded into memory in order to execute its functions and manage the resources of the computer. The different parts of memory are used for different purposes, such as storing the operating system code, data, and variables. Therefore, the operating system can be present in all parts of memory depending on the specific requirements and design of the system.

When the computer system is in the switch on state, the OS software needs to stay in the disk drive. The disk drive is the hardware component where the operating system software is stored. It is necessary for the OS to be stored in the disk drive in order for it to be accessible and loaded into the computer's memory when the system is powered on. This allows the OS to control and manage the computer's resources and facilitate the execution of other software programs.
