COMPUTER HARDWARE- FULL DESCRIPTION

INPUT DEVICES -  
 WHICH DEVICES PROVIDE A INPUT TO THE COMPUTER ,THAT IS     KNOWN AS INPUT DEVICES ,AS GIVEN IN EXAMPLE ALL THE DEVICES PROVIDE THE INPUT . AS KEYBOARD GIVE THE COMMAND TO COMPUTER AND COMPUTER WORK ACCORDING  TO THE COMMAND. FIRSTLY WHEN WE GAVE THE COMMAND TO THE COMPUTER, THEN THAT COMMAND GOES TO THE DEPARTMENT OF THE KERNEL,KERNEL IS THE MIDIATOR OF THE WHOLE PROGRAMMING PHENOMENA , BECAUSE ALL THE COMMAND INSTRUCTION READ BY THE KERNEL. AND AFTER THAT KERNEL CHENGE THE LANGUAGE FORMAT IN HIGH LEVEL LANGUAGE.WHEN LANGUAGE CHANGE THEN COMPUTER OR CPU CAN PROVIDE THE OUTPUT OR RESULT.SO WHOLE GIVING COMMAND AND THE INSTRUCTION IS INPUT AND WHICH HARDWARE PART PROVIDE THIS FACILITIES THAT IS KNOWN AS INPUT DEVICES.
SOME INPUT DEVIVES.        (1) KEYBOARD
                                          (2)  MOUSE
                                          (3) MODEM
                                          (4) USB CARD READER
                                          (5) ROUTER
                                          (6) WEB CAM
OUTPUT DEVICES -    
WHICH DEVICES PROVIDE A OUTPUT THAT IS KNOWN AS  OUTPUT DEVICES. WE CAN REALIZE THE OUTPUT DEVICES. LIKE  PRINTER PROVIDE A OUTPUT PRINT WITH INPUT PRINT COMMAND.   SOUND SYSTEM GIVE THE OUTPUT VOICE AS WE WANT SO ALL THE EXAMPLE OF OUT  PUT DEVICES  THE KERNEL,KERNEL IS THE MIDIATOR OF THE WHOLE PROGRAMMING PHENOMENA , BECAUSE ALL THE COMMAND INSTRUCTION READ BY THE KERNEL. AND AFTER THAT KERNEL CHENGE THE LANGUAGE FORMAT IN HIGH LEVEL LANGUAGE.WHEN LANGUAGE CHANGE THEN COMPUTER OR CPU CAN PROVIDE THE OUTPUT OR RESULT.SO WHOLE GIVING COMMAND AND THE INSTRUCTION IS INPUT AND AFTER INPUT COMMAND WHICH RESULT COME THAT IS OUTPUT .
SOME OUTPUT DEVICES AS------                                                                                                
                                           (1) PRINTER
                                          (2)  SOUND SYSTEM
                                          (3) DISPLAY LIKE TFT, CRT
 
HARDWARE PRODUCT-
HARDWARE PRODUCT.OK,AS THE NAME PROVIDE THE SENSE,WORK IS ALSO LIKE THAT.THAT MEAN WHICH ELEMENT PROVIDE THE HELP TO THE MAKING OF THE COMPUTER SYSTEM ,THATS WHOLE PART IS KNOWN AS HARDWARE ,WE HAVE THE SOME KNOWELEDGE ABOUT THE COMPUTER HARDWARE PRODUCT BECAUSE A LARGE NUMBER OF PEOPLE USE THE COMPUTER AND SMALL SMALL COMPUTER HARDWARE PROBLEMS COME IN FRONT OF YOU AND FOR THE EVERY PROBLEM HE PAY THE MONEY ,SO MY POINT OF WAY WHEN U HAVE SOME KNOWLEDGE OF COMPUTER HARDWARE SO U CAN SORT OUT THE PROBLEM EASILY.HERE WE PROVIDE THE SOME KNOWLEDGE ABOUT THE HARDWARE PRODUCTS ,I HOPE THAT KNOWLEDGE WILL BE SUFFICIENT FOR YOUR SUSTEM,HARDWARE PRODUCT ARE--

• SMPS
• RAM
• HARD DISK
• PROCESSAR
• MOTHER BOARD
• DVD DRIVE
• CABINET
• GRAPHICS CARD
• FAN
• KERNEL

SMPS  -      (SWITCHED MODE POWER SUPPLY) 

THAT IS ELECTONICS POWER SUPPLU SYSTEM,WHICH PROVIDE THE NEEDED POWER SUPPLY OF COMPUTER. WHEN THE POWER SUPPLY IS ON THEN THE FAN WILL BE AUTOMATICALLY RUN,THAT IS SHOW THE POWER SUPPY IS GOING TO THE COMPUTER. THAT IS MANAGE THE WHOLE SUPPLY OF THE COMPUTER.AS SHOWN IN FIGURE THAT HAVE THE ELECTONICS CABLES WHICH PROVIDE THE SUPPLY, ALL THE CABLES CONNECTED TO ELECTRONIC CIRCUIT ,THAT CIRCUIT PROVIDE THE NEEDED POWER SUPPLY TO THE COMPUTER ,SO THE BASIS OF THIS WE CAN SAY IT IS MAIN PART OF POWER SUPPLY,WITHOUT SMPS PART CAN NOT JUSTIFY THE POWER SO THAT IS USE FOR MAINTAIN POWER SUPPLY TO THE PART.SMPS IS A HARDWARE PRODUCT WHIC CONNECT BY SUPPLY CABLE AND OTHER END OF SUPPLY CABLE IS CONNECTED TO THE MAIN POWER SYSTEM.

RAM   -   (RANDOM ACCESS MEMORY)

THAT IS PROVIDING THE ACCESS SUPPORT TO THE PROCESSAR, SO WE CAN SAY PROCESSAR CAPABILITY DEPEND ON THE RAM. RAM ALLOW THE ACCESS SPEED ON THE STORAGE DATA OF COMPUTER WITH THE HELP OF PROCESSAR .RAM IS NORMALLY ASSOCIATE WITH THE VOLATILE TYPES OF MEMORY,MANY OTHER TYPE OF NON-VOLATILE MEMEORY ARE RAM AS WELL. THE FIRST RAM MODULE TO COME INTO THE MARKET WHERE CREATED IN 1951 AND WERE SOLD UNTIL THE LATE 1960 AND ERLY 1970S.  THE FIRST PARTICLE FORM OF RANDOM -ACCES MEMORY WAS THE WILLIAM TUBE STARTING IN 1947.IT STORED DATA AS ELECTRICALLY CHARGED SPOTS ON THE FACE OF CATHODE RAY TUBE .SINCE ELECTRON BEAM OF THE CRT COULD READ AND WRITE THE SPOTS ON THE TUBE IN ANY ORDER ,MEMORY WAS RANDOM ACCESS. THE CAPACITY OF THE WILLIAMS TUBE WAS A FEW HUNDREAD TO ARROUND A THOUSAND BITS.

HARD DISK -  (STORAGE SYSTEM)

HARD DISK IS A STORAGE SYSTEM ,WHICH ALLOW THE ANY KIND OF DATA STORING CAPABILITY.HERE WE CAN STORE DATA IN ANY FORMAT AND THAT DATA WE CAN FORWORD TO OTHER HARD DISK WITH THE HELP OF COMPUTER. SO WE CAN SAY HARD DISK IS A STORAGE DEVICE. A HARD DISK DRIVE IS A DATA STORAGE DEVICE USED FOR STORING AND RETRIEVING DIGITAL INFORMATION USING RAPIDDALY ROTATING DISK CATED WITH MAGNETICS MATERIAL , AN HARD DISK RETAINS ITS DATA EVEN WHEN POWERED OFF DATA IS READ IN ANY ORDER RATHER THAN SEQUENTIALLY . AN HARD DISK CONSIST OF ONE OR MORE RIGID ROTATING DISK WITH MAGNETICS HEADS ARRANGED ON A MOVING ACTUATOR ARM TO READ AND WRITE DATA TO THE SURFACES.

HARD DISK HAVE TWO TYPE- 
                                                                                    1- ENTERNAL HARD DISK 

                                                                                    2- REMOVAL HARD DISK
ENTERNAL HARD DISK, WHICH IS FIX ON THE COMPUTER AND EXTERNAL HARD DISK IS ,WHICH IS FIX BY THE USER SO EXTERNAL HARD DISK CAN MEMORY CARDS ,PENDRIVE AND OTHER HARD DISK LIKE REMOVAL HARD DISK.


PROCESSAR :

WE BEST KNOWN AS CPU (CENTRAL PROCESSING UNIT),AS THE NAME SUGGEST THAT DONE THE WHOLE PROCESSING WORKS, WHICH IS GIVEN BY THE COMMAND.OR GIVEN BY THE USER.ALL COMMAND PASS THROUGH THE KERNEL,KERNEL READ THE COMMAND AND SEND TO CPU IN MACHINE LANGUAGE AFTER THAT CPU PROVIDE THE PROCESING SPEED FOR DOING WORK,SO HERE ONE THING IS VERY CLEAR PROCESSING SPEED DEPEND ON THE CPU SPEED OR CPU CAPABILITY,SO CPU IS VERY IMPORTANT PART OF COMPUTER,WITHOUT CPU WE CAN;T THINK ABOUT THE COMPUTER.
A CPU IS THE HARDWARE WITHON A COMPUTER THAT CARRIES OUT OF INSTRUCTIONS A COMPUTER PROGRAMME BY PERFORMING THE BASIS ARITHMETIC AL , LOGICAL AND INPUT/OUTPUT OPERATONS OF SYSTEM . THE TERM HAS BEEM IN USE IN THE COMPUTER HISTORY AT LEAST SINSE THE ERLY 1960 . THE FORM DESIGN AND IMPLEMENTION OF CPU HAVE CHANGED OVER THE COUSE OF THIER HISTORY.
