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.
advantages of cost management in relation to finacial efficiency
Well, honey, the advantage of a traditional system life cycle is that it's like following a recipe - you know exactly what ingredients you need and when to add them. But, on the flip side, it can be as exciting as watching paint dry, with its rigid structure and lack of flexibility. So, if you're into playing by the rules and don't mind a little predictability, go ahead and embrace the traditional system life cycle.
Some of the advantages are: 1. A file management system will allow user to create and store Meta data. Meta data is data about the files. 2. A file is indexed for faster and easier retrieval. Gives structure to all your info. You will be able to manage all your information much easier. some disadvantages of file management system.:- 1.minimal security of data 2.there is data redundancy 3.it cannot generate queries
advantage of filing system is this that we can easily find our files
Centralized computing is computing done at a central location, using terminals that are attached to a central computer. The computer itself may control all the peripherals directly (if they are physically connected to the central computer), or they may be attached via a terminal server. Alternatively, if the terminals have the capability, they may be able to connect to the central computer over the network. The terminals may be text terminals or thin clients, for example.
what are the disadvantages of centralized database system
is Distributed operating system a centralized OS
The database can be of two types either distributed or centralized . In distributed database the data is in different systems. In centralized database the data is in a single central system.We can categorize database as either distributed or centralized . In centralized database the data is in a single centralized system. While In distributed database the data is in different systems .
Q1: Please give real life examples of one centralized system and one distributed system. Please explain why they are centralized or distributed systems.
The advantages to education system centralization are unified and standardized curricula. The disadvantages are creating one-size fits all approaches and undermining the academic freedom of teachers, instructors and administrators which can limit their ability to serve the needs of their local communities.
Advantages and disadvantages of class system
A free market economy has its advantages as well as disadvantages. Some disadvantages are that a competitive environment creates an atmosphere of survival of the fittest. Wealth is not distributed equally, and there is no economic stability.
