SECURITY FOR INPUT OUTPUT DEVICES

  PROTECTION FOR INPUT AND STORAGE DEVICES  THROUGH BITLOCKER DRIVE ENCRYPTION METHOD.   I    TODAYS DIGITAL AGE.  DATA IS THE NEW OIL.  SO DATA IS HIGHLY RECOMMENDED FOR PROTECTION.  JUST AS THE ELITE COMMUNITY OF COUNTRIES NEEDED PROTECTION SO DOES OUR COMPUTER STORAGE DEVICES NEEDS PROTECTION.  SO I AM GOING TO SHARE MY VIEWS ON PROTECTION OF DATA IN INPUT AS OUTPUT STORAGE DEVICE PROTECTION ALGORITHM KNOWN AS BITLOCKER DRIVE ENCRYPTION.    I WON’T BE EXPLAINING IT BUT I WILL SHOW YOU THE METHOD TO GET THE PROTECTION NEEDED FOR DATA IN OUTPUT AND INPUT STORAGE DEVICES.  SO LET US BEGIN… BITLOCKER DRIVE ENCRYPTION RUN à TYPE GPEDIT.MSC à UNDER COMPUTER CONFIGURATION EXPAND ADMINISTRATIVE TEMPLATES à EXPAND WINDOWS COMPONENTS à SELECT BITLOCKER DRIVE ENCRYPTIONS à DOUBLE CLICK ON FIXED DATA DRIVE à DOUBLE CLICK ON ALLOW ACCESS TO BITLOCKER PROTECTED FIXED DATA DRIVES FROM EARLIER VERSION OF WINDOWS à SELECT ENABLE à APPLY OK à DOUBLE CLICK ON BACK à DOUBLE CLICK ON REMOVABLE D

HOW TO CONFIGURE VIRTUAL MEMORY IN WINDOWS OPERATING SYSTEM?

  HOW TO CONFIGURE VIRTUAL MEMORY IN WINDOWS OPERATING SYSTEM? VIRTUAL MEMORY IS A MEMORY MANAGEMENT CAPABILITY OF AN OPERATING SYSTEM THAT USES HARDWARE AND SOFTWARE TO ALLOW A COMPUTER TO COMPENSATE FOR PHYSICAL MEMORY SHORTAGES BY TEMPORARILY TRANSFERING DATA FROM RAM TO INACTIVE SPACE IN HARD DISK DRIVES TO FORM CONTINIOUS ADDRESESES THAT HOLD BOTH THE APPLICATION AND ITS DATA.  NOW LET US SEE HOW TO CONFIGURE VIRTUAL MEMORY? RIGHT CLICK ON MY COMPUTER --> THIS PC -->PROPERTIES -->ADVANCE SYSTEM SETTING --> PERFORMANCE SETTING -->ADVANCED --> VIRTUAL MEMORY -->CHANGE --> UNCHECK AUTOMATICALLY MANAGE PAGING FILE SIZE FOR ALL DRIVES --> SELECT CUSTOM SIZE  --> TYPE PAGE FILE SIZE IN MEGA BYTES -->  CLICK ON SET ---> OK-->OK--> OK --> RESTART THE SYSTEM.

FLASH MEMORY INSIGHTS

  FLASH MEMORY HELLO FRIENDS TODAY I AM GOING TO TELL YOU   SOMETHING ABOUT WHAT   I KNOW ABOUT A TOPIC KNOWN AS   VIRTUAL MEMORY, SO LETS BEGIN.   VIRTUAL MEMORY IS A MEMORY MANAGEMENT CAPABILITY OF AN OPERAING SYSTEM THAT USES HARDWARE AND SOFTWARE TO ALLOW A COMPUTER TO COMPENSATE FOR PHYSICAL MEMORY SHORTAGES BY TEMPORARILY TRANSFERING DATA FROM RAM TO INACTIVE SPACE IN HARD DISK DRIVES TO FORM CONTIGOUS ADDRESESES THAT HOLD BOTH THE APPLICATION AND ITS DATA.   A SYSTEM USING VIRTUAL MEMORY USES A SECTION OF HARD DISK DRIVE TO EMULATE RAM WITH VIRTUAL MEMORY A SYSTEM CAN LOAD LARGER PROGRAMS LIKE PUBG OR FREE FIRE RUNNING AT THE SAME TIME ALLOWING NO MORE RAM REQUISITE.   WHILE COPYING VIRTUAL MEMORY INTO THE PHYSICAL MEMORY THE OS DIVIDES MEMORY INTO PAGE FILES WITH A FIXED NUMBER OF ADDRESSES. EACH PAGE IS STORE ON A DISK AND WHEN THE PAGE IS NEEDED THE OS COPIES IT FROM THE DISK TO THE RAM.   THIS IS CALLED A PAGE SWAPPING.   SO LETS SEE HOW TO CONFIGURE A VIRT

HARD DISK NOT DETECTED ERROR OR WHAT?

 HARD DISK  NOT DETECTED ERROR OR WHAT? FRIENDS TODAY I AM GOING TO TELL YOU SOMETHING ABOUT AN ERROR THAT OCCURS MOSTLY IN COMPUTERS, THAT IS HARD DISK NOT DETECTED.   SO LET’S BEGIN. THERE ARE THREE ACTION YOU NEED TO TAKE TO THIS PROBLEM SO LET’S BEGIN. STEP 1   CHECK WHETHER THE POWER CABLE AND DATA CABLE OF THE HARD DISK IS PROPERLY ATTACHED OR NOT.  YOU CAN ALSO CHANGE THE PATA AND SATA DATACABLE.   STEP2 CHECK THE SMPS (SWITCH MODE POWER SUPPLY) YELLOW AND RED WIRE VOLTAGE LEVEL.  IF THE VOLTAGE LEVEL IS IMPROPER REPLACE THE SMPS. STEP3 ATTACH THE HARD DISK TO ANOTHER MACHINE.  CHECK IF IT IS DETECTED OR NOT IF THE HARD DISK IS DETECTED IN THE SECOND MACHINE, REPAIR THE MOTHERBOARD.  IF THE HARD DISK IS NOT DETECTED IN SECOND MACHINE REPAIR OR REPLACE THE HARD DISK.

TROUBLE SHOOTING FOR NO DISPLAY IN PERSONAL COMPUTER.

  TROUBLESHOOTING FOR NO DISPLAY FRIENDS TODAY I AM GOING TO TELL YOU ABOUT THE CORRECT STEPS TO BE TAKEN IN ORDER TO REPAIR THE COMPUTER IF THERE IS NO DISPLAY.  MEANS THAT WHEN YOU START THE COMPUTER, THE CPU FAN AND SMPS FAN IS RUNNING ALL LED IS ON BUT THERE IS NO DISPLAY IN THE MONITOR. STEP 1  START THE COMPUTER AFTER 30 SECONDS  PRESS NUMLOCK KEY COUPLE OF TIMES. IF THE NUMLOCK LED IS GETTING ON AD OFF,  THEN THE PROBLEM IS WITH THE MONITOR.  IF THE NUMLOCK LED IS ON OR STEADY ON OR STEADY OFF THEN THE PROBLEM IS WITH THE CPU. STEP2--> SUPPOSE THE PROBLEM IS WITH THE MONITOR  1) CHECK THE AC WALL OUTLET (PLUG) AND POWER CODE WITH THE LINE TESTER OR MULTIMETER.  NOW CHECK THE POWER BUTTON IS ON AND THE BRIGHNESS EVEL OF THE MONITOR.   2) IF THERE IS NO POWER  IN THE MONITOR  THEN THE POWER PANEL MIGHT BE FAULTY.  REPAIR THE MONITOR IF THE POWER LED IS ON, EJECT THE VGA CABLE  FROM THE CPU AND MESSAGE WILL APPEAR ON THE DISPLAY.     3) IF IT DOES THEN THE VGA CABLE OR

BIOS AND ITS LITTLE COMPONENTS

DETAILED ARTICLE ON BIOS AND ITS COMPONENTS Today i am going to discuss something about bios( basic input output system).  So lets get started. A computers basic input output system (bios) is a embedded software on a motherboard.  It is the first software a pc loads to use components such as cd drives, mouse keyboard practically the moment you turn it on. The bios is responsible for controlling or managing low-level but extremely important process like  the power on self test.  It is the boot process and the interaction of components on the motherboard.   the topic will help you to flash (update) you bios by taking right precautions and have a walk through each step.  Not all computers have the same bios manufacturer, let alone the same exact process,  but they all share steps and precautions. UPGRADING THE SYSTEM BIOS When the system was designed, the bios program code will work with all specific devices.  As the computer technology changes we need to update its capabilities .  Genera
