Advantages of Distributed Systems over Centralized ones

1:Incremental growth:Computing power can be added in small

increments

2:Reliability:If one machine crashes, the system as a whole can

still survive

3:Speed:
A distributed system may have more total computing power than a

mainframe

4:Open system:
This is the most important point and themost characteristic point

of a distributed system.
Since it is an open system it is always ready to communicate with

other systems.
an open system that scales has an advantage over a perfectly closed

and self-contained system.


Economic:ANd Microprocessors offer a better price/performance than

mainframes

Disadvantages of Distributed Systems over Centralized ones
1:As i previously told you distributed systems will have an

inherent security issue.

2:Networking:If the network gets saturated then problems with

transmission will surface.

3:Software:There is currently very little less software support for

Distributed system.

4:Troubleshooting:Troubleshooting and diagnosing problems in a

distributed system can also become more difficult, because the

analysis may require connecting to remote nodes or inspecting

communication between nodes.


To design my own distribute system i would do the following:

1:Distributed users always pose a threat to be exposed by

hackers.Therefore I'l create groups of users and will provide them

constrained access to data.

2:Authentication required by all users who use the system.

3:encryption..that is for message protection,

4:The whole Domain is also to be protected via firewalls..so i

would install good Firewalls.

5:Would install good anti viruses on my machines which are a part of the distributed system, as these systems are prone to the domino effect that is if one system gets effected the whole network will be susceptible to becoming effected.

6:Design:
As far as possible I'll keep the design simple and as local as possible.Will probably use a virtual private network.
Will use machines that are compatible with each other.

Will enforce secure access on all users.

Will probably save the most important, the database on another well equipped machine so that it has a system that is only dedicated to look after the database.

Disadvantages of distributed operating system?

More Software Components The more software components that comprise a system the greater chance of errors occuring . Security Providing easy distributed access increases the risk of a security breach occuring . Networking The underlying network can saturate or cause other problems .

Advantages and disadvantages of distributed operating system?

Advantages: Performance : very often a collection of processors can provide higher performance and better price/performance ratio than a centralized computer. Distribution: many applications involve, by their nature, spatially separated machines (banking, commercial, automotive system).

What are the advantages of distributed operating system?

Advantages of distributed operating system include: sharing ofresources, reliability, communication and computation speedup.Distributed systems are potentially more reliable than a centralsystem because if a system has only one instance of some criticalcomponent like CPU.

Advantages and disadvantages of distributed systems?

Advantage : Improved scalability Unlike a single-database system, in which the amount of data that can be stored depends on the limitations of one host and one database, a distributed-database system is easily scalable and, therefore, set up for growth. As more sites or regions become part of

What are the advantages of distribution system?

its is the risk sharing burden .....................it gives u infrastructure such as storage facility, transport facility, ...............it gives u first hand information from the market.......it builts your relationship.........it is usefull for market mapping..............

Advantages and disadvantages of centralized education system?

The advantages to education system centralization are unified andstandardized curricula. The disadvantages are creating one-sizefits all approaches and undermining the academic freedom ofteachers, instructors and administrators which can limit theirability to serve the needs of their local communiti

Advantages of 3wire over 2 wire distribution system?

Advantages: (i) Two different voltages are available-high voltage for power load and low voltage for domestic and light load. (ii) With the same volume of copper, 3 wire dc distribution system is able to deliver more power i.e. twice of that with two wire distribution system without affecting the ef

Advantages and disadvantages of centralized database system?

Centralized databases have the advantage of being fast, and easy tomanage while information is easy to manage. However, it has itsdisadvantages as well. All the information must be stored on aserver and if that server happens to fail, no one can access thedatabase. Having outside servers can remove

Advantages and disadvantages of security systems?

Advantages: They prevent unauthorized access or at least make it more difficult Disadvantages: They require resources to run, add complexity to the IT environment and require effort by those using the systems.

What is the Advantages disadvantages of Distributed Operating System?
