1st Assignment Computer System Architecture

1]Discuss about the following computer system architecture
    i) Single Process System(One Newmann)
    ii)Multi-Process System
    iii)Clustered System
    iv)Mobile Phone Architecture

A process is defined as an entity which represents the basic unit of work to be implemented in the system.

i)Single Process System:-
                                          Single Process System is also called as One Newmann Architecture.
*In this it performs only one process at a given time, and it carries out the next process in the queue only after the current process is completed.
*OS monitors the status of the given program or task and it sends them to next executable instruction.

*It relieves CPU of disk scheduling and other tasks.
*It is suitable for general purpose computers , as it cannot run multiple processes in parallel.
*One of the disadvantages is that we may be irritated or we may have lack of interest performing all tasks one-by-one.How much time will it gonna take to perform the all tasks?

ii)Multi-Process System:-
 *A computer’s capability to process more than one task simultaneously is called multiprocessing.
*. A multiprocessing operating system is capable of running many programs simultaneously, and most modern network operating systems (NOSs) support multiprocessing.

*One of the advantages is High and efficient CPU utilization.
  
iii)Clustered System:-

* A computer cluster is a set of loosely or tightly connected computers that work together so thatthey can be viewed as a single system.

 

iv)Mobile Phone Architecture:-                                                                                                              

* Mobile phone contains a large amount of circuitry, each of which is carefully designed to optimize its performance. 

*The cell phone comprises analogue electronics as well as digital circuits ranging from processors to display and keypad electronics.
