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 far away from each other to cover a wider geographic area which is not the case with parallel processing systems.
4) The no. of processors that can be usefully deployed is very small in a parallel processing operating system whereas for a ditributed operating system a larger no. of processors can be usefully deployed.......
5)globle clock is used for controlling simd n mimd in parallel..... .in distributed no any global colck present in this synchronization algorithms are used
6)in the distributed operating system there is an unpredictable communication delays between processors whereas the processors in the parallel processing system share over an interconnection network

What is the difference between distributed and parallel processing?
Distributed processing involves multiple interconnected systems working together to complete a task, with each system performing a different part of the task. Parallel processing, on the other hand, involves breaking down a task into smaller sub-tasks and executing them simultaneously using multiple processors within the same system. In distributed processing, systems may be geographically dispersed, while parallel processing occurs within a single system.

Which of these is the generally accepted conceptualization of the brain today?
parallel-distributed processing model
What is the difference between supercomputer and distributed computing?
supercomputers allows both parallel and distributed computing
What are distributed and parallel computing?
Parallel computing and distributed computing are ways of exploiting parallelism in computing to achieve higher performance. Multiple processing elements are used to solve a problem, either to have it done faster or to have a larger size problem been solved. To state simply, if the processing elements share the memory, it is called parallel computing, other wise it is called distributed computing. Some have opinion that distributed computing is a special form of parallel computing.

How parallel processing affects the speed of computer processing?
Parallel processing allows the computer to process 2 things at once. However on it's own it doesn't help, computer programs have to be written to use it. Many operating systems are written to take advantage of parallel processing between seperate processes, and some programs are setup to use parallel processing withing their own process.
Difference between concurrent processing and parallel processing in computer architecture?
concurrent processing deals with N-client single server whereas parallel supports N-client N-server
What is difference between distributed operating system and operating system?
Distributed computing is decentralised and parallel computing, using two or more computers communicating over a network to accomplish a common objective or task. The types of hardware, programming languages, operating systems and other resources may vary drastically. It is similar to computer clustering with the main difference being a wide geographic dispersion of the resources. An operating system (OS) is a software program that manages the hardware and software resources of a computer. A key component of system software, the OS performs basic tasks, such as controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating networking, and managing files.
Define Distributed parallel processing?
First, let's define parallel processing. Parallel processing is a computing approach to increasing the rate at which a set of data is processed by processing different parts of the data at the same time. Distributed parallel processing is using parallel processing on multiple machines. One example of this is how some online communities (Folding@HOME, the Mersenne Prime search, etc.) allow users to sign up and dedicate their own computers to processing some data set given to them by the server. When thousands of users sign up for this, a lot of data can be processed in a very short amount of time. Another type of parallel computing which is (sometimes) called "distributed" is the idea of a cluster parallel computer. A cluster would be many CPUs hooked up via high-speed ethernet connections to a central hub (server) which gives each of them some work to do. This cluster method is similar to the method described in the above paragraph, except that all the CPUs are directly connected to the server, and their only purpose is to perform the calculations given to them.
What is the difference between parallel computing and parallel processing?
Parallel processsing ranges from instruction-level parallelism e.g. superscalar and VLIW to message-passing MIMD also called multicomputer, and also includes SIMD e.g. vector and array processing. Multiprocessing is specifically task parallelism, and is by definition shared-memory MIMD with multiple processor cores, sometimes multiple sockets.
