Disadvantages of distributed operating system?
More Software Components
The more software components that comprise a system the greater chance of errors occuring.
Providing easy distributed access increases the risk of a security breach occuring.
The underlying network can saturate or cause other problems.
Mach is an operating system kernel developed at Carnegie-Mellon University to support operating system research, primarily distributed and parallel computation. The project at CMU ran from 1985 to 1994. Several factors were considered in making the Mach operating system. It was important that the operating system be: *Multi-user and multitasking. *Network-compatible. *An excellent program-development environment. *Well-represented in the university, research, and business communities. *Extensible and robust. *Capable of providing room for growth and future extensions.
Advantages Can drastically increase processing speed Can be infinitely expandable - just keep adding computers Security through redundancy Collaborative processing Distributed Database Disadvantages Not all situations are suitable for distributed computing A lot of extra programming is required to set up a distributed system
What is the difference between Centralized System and Distributed System as far as operating system data replicability system memory and homogeinity are concerned?
Advantages of multiprogramming operating system: i) It increases CPU utilization. ii) It decreases total read time needed to execute a job. iii) It maximizes the total job throughput of a computer. Disadvantages of multiprogramming operating system: i) It is fairly sophisticated and more complex ii) A multiprogramming operating system must keep track of all kinds of jobs it is concurrently running.
1) Distributed Operating systems are also referred to as Loosely Coupled systems whereas parallel processin g systems are referred to as tightly coupled systems. 2) A Loosley coupled system is one in which the processors do not share memory and each processor has its own local memory whereas in a tightly coupled system there is a single systemwide primary memory shared by all the processors. 3) The processors of distributed operating systems can be placed…
unfortunately, this question is too subjective to answer correctly. each operating system has it's own advantages/disadvantages that would make it 'more suitable' for the specific requirement. in general, UNIX is considered 'more robust' while WINDOWS is considered 'less secure/stable'. WINDOWS is an 'operating system' that, historically used the 'processor chipset' provided by the INTEL corporation, 'evolved' from a 'local device only' operating system (MS-DOS) to a 'network capable' operating system (MS WINDOWS). UNIX is an…
Distributed and network operating systems, those designed to provide common control for a set of computers communicating through a network. Network operating systems are considered here to be those which provide support for networking and remote resource access, often by a separate layer of software on top of a conventional OS. Distributed operating systems strive for a high degree of transparency and often support data and process migration.Distributed systems intended primarily for real-time applications are…
