Why are modern operating systems designed to implement multiprocessing?

Multiprocessing is based on the fact that computers work much faster than humans. While you type a sentence on your word processor, the computer is doing nothing, waiting for you to hit the 'save' key, or the spellchecker. Because many people want to do as many things at the same time as possible, modern operating systems are designed to be able to have several programs working at the same time. Thus, while a person is Surfing the Web, their email program is checking for new mail. Macintosh was the first multitasking operating system for home computers, followed shortly by Windows. Every window that is open in Windows is a separate application as far as the central processer is concerned, and each one is given a certain amount of processer time to perform whatever processing is needed.
Until recently, the processers in home computers were not fast enough to be able to multitask without a noticable slowing down of the applications. Playing a CD while accessing the hard drive resulted in choppy audio, and slow refresh times on the moniter. However, new proccesers are so fast that many different applications have to be active before any noticable slowdown occurs.

What is processes threads?
different paths of control in a program that a computer might run at the same time if it has parallel processing support for multithread execution. threads and processes are two ways of supporting multitasking on a uniprocessor or multiprocessing on a multiprocessor. threads are lighter weight: take less OS resources to implement but only support limited protection and security. processes take more OS resources but can support full protection and security. Many operating systems support both processes and threads, allowing each process to have many threads.
What is a machine cooling system called?
A machine cooling system is commonly known as a "cooling system" or "cooling mechanism." It is designed to dissipate heat generated by the machine and maintain its temperature within a prescribed operating range. Examples include air cooling systems, liquid cooling systems, and refrigeration-based systems.
Why is it that handheld operating systems have lesser capabilities as compared to PC operating systems?
i would say it is due to the lack of processing power, memory and storage capabilties of the handheld system in comparison to that of a PC, the Operating system will be comparable to that of older PC operating systems developed for less powerful computers. Lots of people say that Linux is the best because it wont get so easily overloaded.
How do I uninstall your operating system to install a new system?
There is no uninstaller for an operating system. To remove an OS, simply format the partition that holds the operating system. If you use a boot manager to choose between different operating systems the software should automatically detect missing operating systems for you.
Properties of Interactive operating system?
An operating system that allows users to run interactive programs. Pretty much all operating systems that are on PCs are interactive OS's
Characteristics of modern operating systems?
Micro Kernel architecture Multithreading Multiprocessing
What is ASymmetric Multiprocessing?
Multiprocessing refers to a computer system's ability to support more than one process (program) at the same time. Multiprocessing operating systems enable several programs to run concurrently. UNIX is one of the most widely used multiprocessing systems, but there are many others, including OS/2 for high-end PCs. Multiprocessing systems are much more complicated than single-process systems because the operating system must allocate resources to competing processes in a reasonable manne
What are operating systems designed to do?
Operating systems are designed to manage computer hardware and software resources
UNIX was one of the first operating systems to implement a file system?
Hierarchical
What are the server operating systems?
A server operating system is an operating system that is designed to run on servers. Some of the operating systems include; Windows, Mac OS, and Linux.
Are most operating systems today designed for either 16-bit or 32-bit CPUs?
Most operating systems are designed for either 32-bit or 64bit CPU's.
What is the operating system designed for businesses?
There are many operating systems designed to be used by businesses. Windows 7 Professional, Mac OS X, Red Hat Enterprise Linux, and SUSE Enterprise Linux. These are all examples of operating systems designed to be used for business, and they are designed to meet the needs of business users.
What operating systems are designed primarily to maximize resource utilization?
Mainframe !!!
6 Describe the differences between symmetric and asymmetric multiprocessing?
Asymmetric multiprocessing - In asymmetric multiprocessing (ASMP), the operating system typically sets aside one or more processors for its exclusive use. The remainder of the processors run user applications. As a result, the single processor running the operating system can fall behind the processors running user applications. This forces the applications to wait while the operating system catches up, which reduces the overall throughput of the system. In the ASMP model, if the processor that fails is an operating system processor, the whole computer can go down. Symmetric mMultiprocessing - Symmetric multiprocessing (SMP) technology is used to get higher levels of performance. In symmetric multiprocessing, any processor can run any type of thread. The processors communicate with each other through shared memory. SMP systems provide better load-balancing and fault tolerance. Because the operating system threads can run on any processor, the chance of hitting a CPU bottleneck is greatly reduced. All processors are allowed to run a mixture of application and operating system code. A processor failure in the SMP model only reduces the computing capacity of the system. SMP systems are inherently more complex than ASMP systems. A tremendous amount of coordination must take place within the operating system to keep everything synchronized. For this reason, SMP systems are usually designed and written from the ground up.
What does the VXWorks operating system do?
The VxWorks is a real time operating system that was developed by Wind River Systems. The operating system was first released in 1987. The operating system is designed for use in embedded systems.
What is the difference between a proprietary operating system and the android operating system?
Proprietary operating systems are commercial operating systems designed to run on specific computer hardware for which they are licensed. Other operating systems such as Linux and OpenBSD are free and open source and can be used on any hardware on which someone can make it work. The Android operating system is a Google implementation of Linux designed to work on smart phones and tablets.
What is nts?
Windows NT ("New Technology") is a family of Operating Systems produced by Microsoft, the first version of which was released in July 1993. It was originally designed to be a powerful high-level-language-based, processor-independent, multiprocessing, multiuser operating system with features comparable to Unix. It was intended to complement consumer versions of Windows that were based on MS-DOS http://en.wikipedia.org/wiki/Windows_NT
