What are the uses of storage area networks in data communication systems?

What are the uses of storage area networks in data communication systems? Storage area networks provide the network that provides the service to store the new data and old data editing system and perform different types of manipulation on the stored file on the SANs. The network model provides the high performance through the SAN because the Storage area network provides the processing power additionally to the network model that already used the server and SANs also uses the servers to process the data inside the SAN model. The SANs included the different types of storage device such as:- SSD, HDD, Tape lib etc. that provide different types of speed of accessing the data from the SANs models used in the network model process for the data communication system. Storage Area Networks (SANs) are widely used in data communication systems to provide high-speed, dedicated access to consolidated storage resources. One of their main uses is to enhance data availability and reliability by allow...

Why is it necessary to maintain the application software?

Why is it necessary to maintain the application software?

The necessary to maintain the application software in the different types of the section of the application software to maintain the application such as system design interface is used to provide the display response to the end user on the computer system.

The maintenance of the application software is a term that includes the maintenance of the system design model, program files, database files, object database file and the security model used to protect the user database on the account on the application software.

To maintain the application software remember some points related to the system design model, programing section, database model, security section on the application software to maintain their files when it is need to manage the file and database on the file of program, design, database and security depends on the requirements of using on current file on the application or any bug file which is used to fix on the application by updating feature.


Introduction to the computer system related topic and the topic is following below here:


Why is it necessary to maintain the application software?


Let's discuss the computer system related topic is mentioned above and the explained following below here:


Why is it necessary to maintain the application software?

There are some points on the computer system and application software development related to the topic of "Why is it necessary to maintain the application software?" following below here:


Why is it necessary to maintain the application software?

  • Maintain the application software system design model for end user
  • Maintain the program for calculation of input values
  • Maintain the database using DML in RDBMS
  • Maintain the security model for user data protection


Let's discuss the points listed above about the computer system and application software development related to the topic of "Why is it necessary to maintain the application software?" explanation following below here:


Maintain the application software system design model for end user

Maintain the application software system design model for the end user that means the end user is used to operate the application software using the interface of the application software to display on the screen of the monitor output device.

Maintain the application in the system design interface to manage the design look and graphics files on the application software to provide a good interface or better display than the previous performance.

The maintenance of graphics is mostly used in the customisation option and settings of graphics to maintain the design interface of the application software.

The maintenance of application in system design model is to change the size of font, colors, theme design, texture etc.


Maintain the program for calculation of input values

Maintains the program for calculation of input values on the application software, the program is used to take input value when the program is dynamic structure then the input value can be maintain through the previous option to re-enter the input value in the program to process the value and provide the output data to the output interface on the particular form of the application software.

Maintain the application software program using the updating feature to add a new program file for increasing the program performance through the new concept of program to process and provide the output data on the output interface of application software.


Maintain the database using DML in RDBMS

Maintaining the database using DML in RDBMS is a type of SQL commands that process the data in the application software at the backend processing system for the end user.

Maintaining the database of the application software is used to process using the DML command means the data manipulation language is used to process the data and manage the data to change the record data in the RDBMS model to manipulate the data such as:- Select, delete, insert, update etc.

These commands are applied on the database file on the application software.

The maintenance of application software in the database file is managed by the DML on the record of relational database model to perform DML operations on the RDBMS file on the application software.


Maintain the security model for user data protection

Maintain the security model for user data protection that means the security model needs to maintain the security layer to improve the security layer and analyze the requirements on the security model to improve the security interface and model for more protection on the application software.

Maintain the database also on the security model because the security interface need to take new option on the security layer of the application softwares due to maintain the security model for increasing features and provide the database with new concept on the security layer and its program to process the input value for verification on the computer system using the different types of input resource on the security layer on the computer system.

Security data can be managed through the manipulation of password data for verification; that means the end user can change the data in the forgotten option to manage and remember the right password.

About the memory and its Classification of the computer Memory

"Hi everyone, I'm Rudra, a CS engineer and passionate blogger. Welcome to my post on [About the memory and its Classification of the computer Memory. ], where I'll share insights on Information Technology and Computer Science education. My goal is to provide helpful information and answer your questions. Feel free to ask me anything in the comments below. Let's dive into today's topic…🙂” What are the memories in the reference of computer system? What is Computer Memory?:- The memory is the essential for the computer to store the data, instruction and information. Without memory, computers are not be able to store data, instruction etc. The memory is an essential part of a computer system. It is require by the computer system to store information. Memory can be divided into the following two categories types: i) Primary or Main memory ii) Secondary Memory or Permanent memory In this figure I'll show the classification of the memory of computer s...

Describe the different ways of mobile communication systems for users?

Describe the different ways of mobile communication systems for users? Mobile communication makes it easy to connect with many users through the different types of ways to provide the communication system, share the information to each other and make communication between two or more users through the mobile devices. Such as:- an internet service provides many ways to connect the users in the text, audio, image and video file or data connections sharing the information to each other using these data types to communicate to each other. The user needs to communicate with the other user on the data communication system application software provide the process the data to send the file or message to the user who is connected to the communication application software through their user ID name or email to communicate to share the text or audio file or video file or image file also can be shared into the application software to the user such as:- if the application software provide the chatt...
