What is information access from the internet service on the computer for the user? The information is based on the two or more data having a relation or connection to each other to make an information for the user or make sense and have some meaning. The record can be accessed from the database linking system from the distributed database model to provide the information access system through the remote database information access from the query performed on the database based on the database links. Such as:- the SELECT command is used to provide the display feature to see the information in the form of the record from the table selected in the command with the name of table to access the information from the database files. Information access from the internet service on the computer allows users to retrieve, view, and use a vast range of data and content available online. Through an internet connection, users can access websites, download files, communicate via email or messaging app...
"Hi everyone, I'm Rudra, a CS engineer and passionate blogger. Welcome to my post on [about the CPU and its units io unit, control unit and ALU ], 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…” 🙂
Central processing unit (CPU)and its units input unit, storage unit, control unit and ALU
The CPU is a main part of the computer. It control all the peripheral device of the mother board.
The primary function of a CPU is to execute instruction or programs. Besides it also controls the operation of all other components, such as memory, input and output devices. Under the processing unit control, Programs and data are accepted from the input devices and stored in the memory. Outputs are displayed on the video screen or printed on paper once the processing of a program is complete.
The processing unit of a small computer normally has a single processor, Whereas the one for a bigger computer may contain a number of processors. Each processor, in a large processing unit, performs a specific task assigned to it.
In this figure the solid lines are shows us to indicate the flow of data and also flow of the instruction.
The dotted lines represents the control exercised by the control unit.
The figure shows the basic arrangement of different units of a computer.
CPU: The figure shows the Central
Processing unit is the combination of the Control unit and Arithmetic logic
unit that are connected to each other permanent line as shown in the above
figure.
Input
Unit: The input
unit works with Control Unit, Storage Unit and Arithmetic Logic Unit in the
execution of the instructions.
Storage
Unit: The
storage unit stores the instruction of the input signal or instruction which is
controlled by the control unit and calculated by the arithmetic and logic unit
in the CPU processing system for making to prepare the output signals or the instructions.
Controls Unit: The control unit controls the instruction of the input signals are where that transfers the in the storage unit and also to set timing of the execution to execute to output signals or instructions.
Arithmetic Logic Unit: In this unit the coming instructions in the storage unit the A.L.U. calculates the instructions in the form of Arithmetic and logical to prepare output form results and after prepare the result the control unit is decides to sends the results to output unit to the resources.
Can a CPU use a cache memory on a computer?
Yes, it is true that the cpu can access the cache memory as their schedule to access the primary memory to process the held program which is ready to be executed on the computer after processing through the cpu.
The cache memory approx in 4mb of storage space increases the fast processing and reduces the cpu processing speed to reduce the loads of many programs.
The programs can be stored depending on their schedule of the cpu to store the program into the cache memory and when the cpu is ready to process then access cache memory on the computer to execute the program on the operating system.
