Explain some points on the data access control in web application software? The web application software needs to protect data which is connected to the user account on the web applications software such as:- name, city, email address, private posts and videos and images etc. The user needs to protect their database files into the web applications used through the authentication system on the user account before accessing it; they need to verify some queries on the layer that is known as the security layer. The security included the authentication process to verify the detail which the user enters in the web application software such as:- password and name with unique special characters in the security model in the web application then verify if they are correct information and matches from the security saved database which is already setup and saved by the user who has an account on the web application software. Data access control in web application software is a critical aspect of s...
Hi everyone 👋 I am Rudra CS engineer and blogger as my passion… Here I am writing a post related to Information technology and Computer science education. I hope every blog post is really helpful for you and my aim is also to provide better information and I daily update posts…
I am here to explain the topic of “ Basic Structure of Computer ” and I hope you can learn from this post that I have posted about “ Basic Structure of Computer ” please keep in mind if you have any questions then comment below the comments put your question then I will be provide you the correct answer of the question but I am also continuing searching for new queries for you to give your curious answer. Let's discuss some questions and their answers with some points mentioned in the post and topic following below here 👇🏻🙂
Keep also reading at the below have some updated new questions that I have mentioned at the end of the post … happy learning ☺️
Basic Structure of a Computer or Anatomy of a computer:-
There are some parts of a computer and its functional units that we can assemble and also we can say that its hardware parts of the computer are following
1- CPU (Central Processing Unit)
2- Input parts (Mouse, Keyboard, Joystick, Mic)
3- Output parts (Speaker, Monitor, Printer)
4- Storage Devices (Hard Disk Drive [HDD], Pen drive, Memory Card, Compact Disk-CD etc)
5- Mother-Board
6- RAM-Random Access Memory
7- ROM-Read Only Memory
8- UPS-Uninterrupted Power Supply
9- S.M.P.S.- Switched Mode Power Supply
The most useful part of the computer is cpu.
CPU is the brain of the computer. The other parts are used to transfer data and to communicate with the CPU.The CPU Constitutes the main memory, Control unit and Arithmetic logic unit.
Inputting in a computer:-
Refers to the process of entering data into the computer with the help of an input device such as a Keyboard and mouse.
Storing in a computer :-
Refers to the storage of data and instructions in the computer of the main parts of the memory for manipulations.
Processing of a computer :-
Refers to the performing of operations (both arithmetic & logical ) or manipulation of data entered into the computer so that useful information may be gathered from the entered data.
Outputting of the computer:-
Refers to the process of showing the information or results to the user either on screen (monitor) or on paper (through printer).
Controlling of the computer:-
Refers to the directly all the above processes, in coordinate. This controlling is done by the Control Unit (CU) in a CPU.
Note that "A CPU is the brain of the computer. Its primary function is to executes programs."
In the addition of the computer in CPU also controls the operation of all other components, such as memory, input and output devices. Under the CPU is control, program and data are stored in the memory and results are displayed on the monitor or printer on paper.
Can the control unit control the input resources?
The control unit controls flow of data that means the flow of input data which comes from the input resource that processes in the CPU through the ALU and is controlled by the control unit using a timeclock system applied depending on the control unit.
The flow of data which can come from the input resources controlled by the control unit of cpu and also output resources data flow controlled by the control unit to get the data transfer to the output unit to the output resources through the data busses controlled by the control unit on the computer system.
A data flow can also be controlled between the connection of a storage device to the CPU to apply commands to store the data into the memory controlled by the control unit and the data flow is scheduled from the control unit using the time clock system of the CPU.
