C.P.U. REGISTER'S

CPU REGISTER' S
Register's are most important components
Of C.P.U. , which performs different types
of functions .
Like storing the data.Registers are used to store data temporarily during the execution of a program.

Following are the types of register's :
1) Program Counter (PC):
PC register is use to store the memory address of upcoming instruction for execution .
It also called as instruction pointer.
2) Instruction Register (IR):
When any instruction is processed from main memory (RAM) or executed
then that instruction is hold under IR or instruction register while it is decoded

Extra: for example : only for understanding
When we are taking admission in our college then first we have to take form from Xerox center and then after completing process we WIN 😉 the pink receipt . We can't take it directly na... ..
3) Memory Address Register (MAR) :
This register stores the memory address of data which either fetched or store by the CPU.
4) Memory Buffer Register (MBR) :
It stores instruction and data which are received from the memory and sent from the memory.
5) INPUT OUTPUT ADDRESS REGISTER (I/O AR) :
IT'S stores or explain the address of any I/O device.
6) INPUT OUTPUT BUFFER REGISTER (I/O BR):

I/O Buffer Register is used for sharing the data between the I/O module and the processor.
 # Accumulator: This is the  register which used to store data taken from memory. Its number varies from microprocessor to microprocessor.

Computer Architecture.

# DEFINITION OF C.A. :   Computer Architecture is a set of C.P.U., Memory and I.O. modules. Means interaction of software and hardware to form computer system which performs analysis of data.

Computer Architecture is also called as Computer Organization because it organize the data
# In our study we have 3 points:

1.C.P.U.
2.Memory
3. I. O. Modules 

this is the diagram of C. A. Working.



1.C.P.U. :
A computer's CPU handles all instructions it receives from hardware and software running on the computer. Microprocessing unit is components(synonymous) to central processing unit, CPU used in traditional computer.
2. Memory
Memory architecture also explains how binary digits are converted into electric signals and then stored in the memory cells. And also the structure of a memory cell.
(Refer to 1 note for more information about memory)
Extra 

This diagram shows how the
Input is converted into output in memory Architecture .

3. I. O. Modules :
I. O. Modules are connectors (postman) between computer systems ( processor) and the i.o. device's. And controls the data between external device's and main memory.
Extra
I. O. =Input/output
I. O. Devices:
I. O. Device are any type of hardware which we used to send or receive the data through computer.
Example.
CD/DVD-ROM drives, USB flash drives and hard disk drives.

C.O. 1

1.BASIC FUNCTIONAL UNITS 

#computer .A computer is a electronic and digital device which takes information (data) from user in a particular form and manipulate it to produce a result in the form of information or signal .

# the data given by user is processed by computer according to given path

1.Input: This is the process of entering data and programs in to the computer system by using the input devices.

2. Storage (Memory): The process of saving data and instructions entered into computer using input units permanently is known as storage.which only deleted by user.

Storage are mainly divided into :

# Permanent memory 

# Main memory 

# Cache memory 

3. Processing: The task of performing operations like arithmetic and logical operations is called processing.

The processing carry out in computer into two units :

1.ALV

2.Control units 

1.ALV (Arithmetic Logical Unit) : 

After storing the data the actual processing performed by Arithmetic Logical Unit. Like (addition, subtraction, multiplication, division, logic and comparison.)

2.Control Unit (CU)

The next uint of computer is the Control Unit, which acts like the supervisor seeing that things are done in proper way  .

4. Output: This is the process of producing results from the data for getting useful information.which are displays on the screen of monitor.

# this is the path:
