Distributed Operating System
A distributed operating system (DOS) is an essential type of operating system.
Distributed systems use many central processors to serve multiple real-time applications
and users. As a result, data processing jobs are distributed between the processors.
It connects multiple computers via a single communication channel. Furthermore, each
of these systems has its own processor and memory. Additionally,
these CPUs communicate via high-speed buses or telephone lines. Individual systems
that communicate via a single channel are regarded as a single entity. They're also
known as loosely coupled systems.
This operating system consists of numerous computers, nodes, and sites joined together
via LAN/WAN lines. It enables the distribution of full systems on a couple of center
processors, and it supports many real-time products and different users. Distributed
operating systems can share their computing resources and I/O files while providing
users with virtual machine abstraction.
, Types of Distributed Operating System
There are various types of Distributed Operating systems. Some of them are as follows:
1. Client-Server Systems
2. Peer-to-Peer Systems
3. Middleware
4. Three-tier
5. N-tier
Client-Server System
This type of system requires the client to request a resource, after which the server gives
the requested resource. When a client connects to a server, the server may serve
multiple clients at the same time.
Client-Server Systems are also referred to as "Tightly Coupled Operating Systems". This
system is primarily intended for multiprocessors and homogenous multicomputer.
Client-Server Systems function as a centralized server since they approve all requests
issued by client systems.
Server systems can be divided into two parts:
1. Computer Server System
This system allows the interface, and the client then sends its own requests to be
executed as an action. After completing the activity, it sends a back response and
transfers the result to the client.
2. File Server System
It provides a file system interface for clients, allowing them to execute actions like file
creation, updating, deletion, and more.
Peer-to-Peer System
The nodes play an important role in this system. The task is evenly distributed among
the nodes. Additionally, these nodes can share data and resources as needed. Once
again, they require a network to connect.
