Since they're network-based, all the complications of schedule kick in, therefore creating distributed file systems a lot of advanced than regular computer file systems. The minicomputer model is a simple extension of the centralized time-sharing system. An operating system does the following activities related to batch processing − 1. As shown, in distributed database system, data is spread across a variety of different databases. As a bridge, it makes it possible for two distinct systems to communicate as Middleware programs move data from one application to another, enabling seamless connectivity. This increased complexity takes various forms :-. For example, a bank has many offices in different cities. Disadvantages of Operating System. We will see reasons to use and not to use different operating systems, we are going to present a list of reasons why you should choose Microsoft Windows. Failure of the main system will affect the whole system. There are several definitions on what distributed systems are. Both Users and hardware, softwares are distributed. Distributed computing systems are difficult to deploy, maintain and troubleshoot/debug than their centralized counterparts. The increased complexity is not only limited to the hardware as distributed systems also need software capable of handling the security and communications. The deployment cost of a distribution is higher than a single system. Because of this reason few firms had less number of computers and those systems were operated independently as there was a lack of knowledge to connect them. Disadvantages of Parallel Systems.

The OS … Database optimization is difficult in a distributed database. Disadvantages:1. Since the data is accessed from a remote system, performance is reduced. The added complexity required to ensure proper co-ordination among the sites, is the major disadvantage. Real-Time Operating Systems are much better-suited for use in embedded systems than General Purpose Operating System’s, and more efficient in many cases (Arthur, 2017). Real-time systems usually are in strong interaction with their physical environment. As a final example, we look at distributed systems support financial trading markets. While users can use a free OS but generally they are a bit difficult to run than others. Moreover, operating systems such as Microsoft Windows with GUI functionality and other in-built features carry a costly price tag. If the central operating system fails, it will affect the whole system, and the computer will not work. A Real-time system is a computer system in which the correctness of the system behavior depends not only on the logical results of the computations but also on the time when the results are produced.
