Nt1330 Chapter 1

Merriam-Webster Online Dictionary (n.d.) defines an interruption as “a break in the continuity or uniformity of; to stop or hinder by breaking in”. The context may apply to seasons, humans, or in computer terms. In computer terms the definition includes a feature of a computers that permits the temporary interruption of one activity to perform another ("Interruption," n.d.). Cambridge dictionary defines interruption as “an occasion when someone or something stops something from happening for a short period”, in business language it would include an occasion when a company is prevented from operating as normal ("Interruption," n.d.). The MacMillan dictionary defines an interruption as ‘something that someone says or does that stops someone else when they are speaking or concentrating on something’, ‘the act of stopping something for a period of time’, and ‘a time during which something interrupts a process or activity’ ("Interruption," n.d., expression 1-3). In assessing synonymous terms break, interference, disruption, disturbance, and discontinuance are the predominant terms found (Thesaurus.com, 2016). The definitions lead us to believe an interruption is always attributed to a thing or a person, however, mostly the

hit by a bus. To mitigate this, hire additional resources or cross train resources to handle the system/hardware as a backup function in the even he/she is

a. Mainframes or minicomputer system: In a mainframe or minicomputer system the resources to be taken care of are :

Symmetric multiprocessing treats all processors similarly. I/O can be processed on any processor. The processors interconnect with each other as needed. It allows many processes to be run at once without corrupting performance. Symmetric multiprocessing treats all processors similarly. I/O can be processed on any processor. The processors interconnect with each other as needed. It allows many processes to be run at once without corrupting performance. Three advantages of multiprocessing are: Increased throughput - with more processors, more work can be accomplished in less time; Economy of scale - peripheral devices may be shared amongst multi-processor systems; increased reliability - if one processor crashes, then the others may continue to operate. One disadvantage of a multi-processing system is the added difficulty in operating system and possibly application software. Another limitation of SMP is that as microprocessors are added, the shared bus get overloaded and becomes a performance bottleneck. Symmetric Multiprocessor Master-slave multiprocessor is not reliable as if the master processor fails the whole system goes down.

3.8) Scheduler: Scheduler in an operating system selects the next process to be admitted into the system and next process to run. The three schedulers and their differences are as follows:-

1.13)Ans.Mainframe or Minicomputer: The resources which has to be managed carefully are memory and CPU resources and the network bandwidth,

In centralized computer or minicomputer frameworks the assets like memory, stockpiling of information and system data transfer capacity ought to be managed carefully.

The host sets the command ready bit in the command register to notify the device of the pending command.

In Chapter 1, you learn the basic knowledge you need to know in order to operate and navigate through Windows 10, as well as the basic components of the computer. This chapter teaches you the function such as the universal serial bus, how to turn your computer off and on, how to use your mouse, understanding desktop, start menu and its programs, icons, and about tiles. If you’re just learning how to operate a computer knowing this information is essential. For the most part I knew this information but I did learn that you can pin an app to the start menu for easier access.

The threads of the system need to communication and to be synchronized in a timely efficient and predictable way.

Since the invention of the first computer, engineers have been conceptualizing and implementing ways to optimize system performance. The last 25 years have seen a rapid evolution of many of these concepts, particularly cache memory, virtual memory, pipelining, and reduced set instruction computing (RISC). Individual each one of these concepts has helped to increase speed and efficiency thus enhancing overall system performance. Most systems today make use of many, if not all of these concepts. Arguments can be made to support the importance of any one of these concepts over one

Distributed System: Is an interconnection of two or more nodes, but the processors do not share memory.

Major distributed file systems like NFS, PVFS, HDFS, GFS have compute and storage node located at a distance apart interconnected via shared link to perform I/O operations. Even though the network bandwidth is high enough to provide fast data transfer but when the day comes for the exascale systems it would not be adequate for data intensive applications. Cost of the hardware and overall efficiency of the systems are the two major factors in deciding the future of the HPC systems. With the ever-increasing data in cluster computing the cost of the storage and hardware for radical performance is increasing exponentially. N number of hardwares running m number of process or threads to get extremely high parallelism, concurrency and resilience out of HPC systems is a real deal.
