Multi user Operating System

 Multi user operating system

·         In a multi-user operating system, multiple number of user can access different resources of a computer at a same time.

·         The access is provided using a network that consists of various personal computer attached to a mainframe computer system.

·         The various personal computer can send and receive information to mainframe computer system.

·         The example  of multi-user OS are UNIX, windows 2000,novell netware.

Advantages of multi user operating system

·         It helps in the sharing of data and information among different users.

·         It also helps in the sharing of hardware resources such as printer and modems.

 

Disadvantages of multi-user

·         It requires expensive hardware to setup a mainframe computer.

·         When multiple users log on or work on same system it reduces the overall performance of system.

Thread

Thread What is Thread? A thread is a flow of execution through the process code, with its own program counter that keeps track of which instruction to execute next, system registers which hold its current working variables, and a stack which contains the execution history. A thread shares with its peer threads few information like code segment, data segment and open files. When one thread alters a code segment memory item, all other threads see that. A thread is also called a  lightweight process . Threads provide a way to improve application performance through parallelism. Threads represent a software approach to improving performance of operating system by reducing the overhead thread is equivalent to a classical process. Each thread belongs to exactly one process and no thread can exist outside a process. Each thread represents a separate flow of control. Threads have been successfully used in implementing network servers and web server. They also provide a suitable foundation ...

Multi Level Queue Scheduling (MLQ)

  Multi Level Queue Scheduling (MLQ) ·          Multilevel queue scheduling classifies the processes according to their types for example, a multilevel queue scheduling algorithm makes a common. ·          In this scheduling ready queue is divided into various queue that are called sub queues. A subqueue is a distinct operational queue ·          The process are permanently assigned to subqueues, generally based on some property of the process such as memory size,priority or process type ·          Each subqueue has its process sucheduling algorithm. For example interactive process at the foreground may use round robin scheduling while batch jobs at the background may use the FCFS method ·          For example, consider a system with four different queues 1.   ...

Multitasking System

  Multitasking system ·           Technically , multitasking is same as multi programming ·           In a multitasking operating system, s single user can execute multiple programs at the same time ·           We can also say, multitasking is the system capability to work on more than one job or process at the same time. ·           It means that whenever a job needs to perform I/O operation, the cpu can be used for execting some other job                                                        diagram of multi tasking     ·           There are two type of multitasking : 1.       ...

Distributed system

  Distributed system ·           A distributed system is a collection of processor located in geographical dispersal physical location. ·           In this system, the workhold is distributed or divided between two or more computers that are linked together by communication network . that is the different processors communicate using communication links, such as telephone lines and buses3 ·           The various processors do not share memory, clock ,or peripheral devices instead each processors has its local memory. ·           The purpose of distributed system is to provide an efficient and convenient environment for sharing of resources. ·           Some example of distributed operating system are amoeba, angle, chorus, much, alpha kernel. ·   ...

Layered Operating System

  Layered Operating System Layered Structure is a type of system structure in which the different services of the  operating system  are split into various layers, where each layer has a specific well-defined task to perform . It was created to improve the pre-existing structures like the Monolithic structure ( UNIX ) and the Simple structure ( MS-DOS ). Example –  The Windows NT operating system uses this layered approach as a part of it . Design Analysis : The whole Operating System is separated into several layers ( from 0 to n ) as the diagram shows. Each of the layers must have its own specific function to perform. There are some rules in the implementation of the layers as follows. The outermost layer must be the User Interface layer. The innermost layer must be the Hardware layer. A particular layer can access all the layers present below it but it cannot access the layers present above it. That is layer n-1 can access all the layers from n-2 to 0 but it canno...
