Subjective Short Answer

  1. Describethedifferencebetweena server operating system and a desktop operating system.

ANSWER: A desktop operating system typically is one installed on a personal computer usually used by one person and often connected to a network. A server operating system is typically installed on a more powerful computer that has a wired connection to a network, and can act in many roles to enable multiple users to access information, such as e-mail, files, and software.

  1. Describetheroleofa resource manager.

ANSWER: A resource manager manages memory and central processor use to prevent memory conflicts and ensure that no single program dominates all the processing time.

  1. Describethefunctionofa device driver.

ANSWER: The device driver contains the actual code to communicate with the chips on a hardware device. If a new piece of hardware is introduced into the computer, the operating system code does not have to change to communicate with the new device. You simply need to load the new hardware's device driver onto the operating system.

  1. DescribetheroleoftheBIOSona computer.

ANSWER: The BIOS, which is stored on a flash memory chip, is low-level program code that initiates and enables communications with hardware devices and performs tests at startup. The BIOS performs an accurate memory and hardware components test called the power-on self test (POST). It also conducts basic hardware and software communications inside the computer and starts a full-fledged operating system that interfaces with the user.

  1. Describethedifferencebetweena mainframe computer and a PC-class computer.

ANSWER: A PC-class computer is designed for individual users to perform tasks such as word processing, database and spreadsheet management, and networking with other computers. PC computers, varying in size and shape, are designed for individual users. Mainframe computers are very large and are designed for multiuser operation, databases, and conduct massive calculations or manipulate large huge amounts of data.

  1. Describethedifferencebetweena time-sharing system and a real-time system.

ANSWER: A time-sharing system is a central computer system that is used by multiple users and applications simultaneously. Most of the time-sharing system's work is done in batches, using batch processing. A real-time system is an operating system that receives and processes inputs and produces the required outputs in a specifies amount of time. A real-time computer program immediately performs calculations and returns the answer using sequential processing instead of batch processing.

  1. ListanddescribethethreetypesofcloudmodelsdescribedbyMicrosoft.

ANSWER: A Private cloud is where computing resources are kept within an organization and used exclusively by that organization.

A Hosted private cloud is where resources are made available through a third-party, but are only accessible to users within a specific organization.

A Public cloud is where a variety of resources are available to any organization through a third party and each organization subscribes only to specific resources, which may also be shared by other organizations.

  1. Describethedifferencesbetweencooperativemultitaskingandpreemptivemultitasking.

ANSWER: In cooperative multitasking, the operating system hands over control to a program and waits for the program to give control back to the operating system. Whereas, in preemptive multitasking, the operating system is in control of the computer at all times. It lets programs execute a little bit of code at a time, but immediately after the code executes, it forces the program to relinquish control of the CPU back to the OS.
