What are the four main objectives of distributed systems?
Introduction of transparency of the distributed systems:-
The user can share the user interface of the operating system of the computer system that provide the user interface and functionality for performing the task on the distributed system that provide the service without disturbing or buffering of task and the user doesn't need to waiting for the results if the one system failure.
The user easily uses the database and access the information from the particular computer system and resources which are connected in the distributed systems.
The user can use the data which is saved on the other computer but the computer location is hidden from the user interface to use the distributed system as the distributed is same for all users on the distrbuted system to use the services.
Distributed systems can be increases the system for enhancing it known as scalability:-
The objective of distributed system increases the computer systems and resources for enhancing the functionality and service to the user on the distributed systems which provides many users can interact with the same operating system and uses more the particular task or project within the distributed systems.
Such as:- if the many users uses the task of 100 document preparation to complete with 100% and data integrity applied on the 100 document file content or database.
In the distributed systems many users performs different types of task on every document file in the form of editing work, creating the database in the blank, adding security layer as the document protected etc. And these documents files are distribted in every users on their computer system with the 20 users to complete their task or project on the distributed system.
If the 100 document files are need to be completed as a project then 20 users to complete the document which is equally distributed to those then:-
= 100/20
= 5 document files are distributed for each users on the distributed systems.
Credibility of the distributed system for the functioning:-
The user performing a task on the distributed system and the computer system fail their functions then the user can continue the task on the distributed system.
If the user's system will failure then the other computers and resources are working for completimg the task on the distributed system.
The credibility is a reliability of rhe distrbuted system that means the project work will completed because the tasks of project will continue for their completion to provide the completed project.
If two users are working for the program development on the project of application software as a minor project but the user1 system has failure then the other user2 is continuing without disturbance of user1 system failure and the working will be completed as commited to complete. This is an objective of distributed system is reliability which is mostly used in the different types of company for performing many types of tasks given on the distributed systems.
The distributed systems shares the hardware devices:-
In the distributed systems shares the hardware devices to perform a task depends on the commands given to the specific Hardware connected to the computer system or server or other network device to perform a task on the hardware device to provide the output data as a result to the user.
The hardware resource sharing system in the distributed system is also an objective to give a service of using any hardware which is connected in the distrbuted systems and perform a task on the hardware resource.
Such as:- if two printers are available for each two computers connected in the distrbuted system and the one printer is failure to perform a task as the user given to perform a task of print out the document file.
Then the user can take second printer connected to the second computer system to perform a task of printing the document file on the computer system which means the printer is a hardware resource or output resource on the distrbuted system which provides an output data in the form of hardcopy of the document file.
Introduction to the computer related topic of computer application and system technology topic is following below here:
What are the four main objectives of distributed systems?
Let’s discuss this topic following above the related topic of computer application and system technology and explanation following below here:
What are the four main objectives of distributed systems?
There are some points on the computer system and database technology related to the topic of “What are the four main objectives of distributed systems?” following below here:
- User can interact the user interface of the other computer system in distributed systems
- The database is also shared as a distributed database in the distributed systems
- Distributed systems can be increased by adding more computer systems
- The hardware resources can be shared in the distributed systems
Let's discuss the points listed above about the computer system and database technology related to the topic of “What are the four main objectives of distributed systems?” explanation following below here:
User can interact the user interface of the other computer system in distributed systems
User interface is a graphical interface with included the functionality and services for the user to use the functionality to get the result from the program or services active on the computer system.
In case the user system need to access some information from the other connected computer then the user can take a feature of transparency of the distrbuted system to access as a same computer to all computer system as working for the same task and provide the database also and resources can share in the other computer system.
The Transparency of distributed computer systems doesn't provide the location of the specific computer system only the user can easily acces the user interface which is distributed to all the computer as a part of a distributed system can share their transparency of the application server software.
The Transparency included complexities hiding of the hardware or resource location that means how they are connected, hide complexity of accessing other computer system, and failure of other computer system. This system creates a same user interface for all the users are using the same distributed systems.
The database is also shared as a distributed database in the distributed systems
The distributed systems uses the distributed database files on every users to access the same database file which is user can work for the same project to complete and perform the task on the same database file.
The server also can be used if the database server need to be process for the project at the backend processing system.
The distributed database system provide the flexibility of the accessing the lost data or system failure to access the information which is distributed to all types of computer as a part of the distrbuted systems.
The user can use and manipulate the database file such as:- an editing work on the database file to update a new information for all types of user are working with the same database file in the same application software which is distributed to all users as a part of a distributed systems and uses the database file.
Distributed systems can be increased by adding more computer systems
Distributed systems can be enhanced by adding more computer systems to increases many users to reduces the work load of a single users on the same project or task given on the distributed users in the distrbuted systems.
If the user performing a task of program development and the program files are: 14 program files and user1 have a burden increases on the project work of developing the program files but the enhancement of distributed reduces the workload of the user if 7 users are added during enhancing the distributed system then the workload of program files will be:
= Program files/number of users (as distributed systems)
= 14 / 7
= 2 program files are distributed for each users working on the same project on the distributed systems.
This feature is a scalability of the distrbuted systems to reduces the work load of employees in the same department of the company to grow their business.
The hardware resources can be shared in the distributed systems
The hardware resources can be shared which means the resource sharing on the distributed systems to provide the service for the users to perform a task such as:- a webcam is used to record the video file which is used to distributed on the distributed systems or many computers can access the same file distributed to each other.
The users can watch the same video as a part of the distrbuted system of the computer and the resources also can be shared when the user 1 connect the webcam on their computer and user 2 access the webcam resource on the computer system because the hardware resources can be shared in the distrbuted system to use the same device.
Similarly, the video chatting can be performed as a group chat and users can see to each other when they connected in the same distributed application software with the shared resources that working with the distributed application software such as:- speaker output device, microphone, webcam and monitor etc.
