distributed Coordination in Operating system
Definition
– In this article, we will fully explain distributed operating system. Distributed operating system allows distributing of entire systems on the couples of center processors, and it serves on the multiple real time products as well as multiple users. All processors are connected by valid communication medium such as high speed buses and telephone lines, and in which every processor contains own local memory along with other local processor. According this nature, distributed operating system is known as loosely coupled systems. This operating system involves multiple computers, nodes, and sites, and these components are linked each other with LAN/WAN lines. Distributed OS is capable for sharing their computational capacity and I/O files with allowing the virtual machine abstraction to users
Types of Distributed Operating System
Classification of distributed operating system Can be done in three areas, such as
=> Client-Server Systems
Peer-to-Peer Systems
Middleware
1. Client-Server Systems
Client-Server Systems is known as “Tightly Coupled Operating System”. This system is designed mostly for multiprocessors and homogeneous multicomputer. Client-Server Systems works as a centralized server because it provides the approval to all requests, which are generated by client systems side.
2. Peer-to-Peer System
Peer-to-Peer System is known as a “Loosely Couple System”. This concept is implemented in the computer network application because it contains the bunch of processors, and they are not shareable memories or clocks as well. Every processor consists own local memory, and these processors make communication with each other through various communication medium such as high speed buses or telephone lines.
3. Middleware:
Middleware allows the interoperability in the between of all applications, which are running on other operating systems. With using these services those applications are capable for transferring all data each other.
Distributed Operating System Example
Here, huge list of distributed operating system. Read each one carefully
LOCUS
In LOCUS operating system, can be accessed local and remote file in simultaneously without any location hindrance.
MICROS
MICROS operating system maintains the balance load of data while allotting the jobs to all nodes of entire system.
IRIX
IRIX operating system is used in the UNIX system V and LINUX. DYNIX DYNIX operating system is developed for the Symmetry multiprocessor computers.
AIX
AIX operating system is designed for IBM RS/6000 computers.
Solaris
Solaris operating system designed for SUN multiprocessor workstations.
Mach
Mach operating system allows the multithreading and multitasking features.
