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 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.  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.

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.

WHAT TO DO WHEN A COMPUTER FREQUENTLY RESTARTS?

  COMPUTER FREQUENTLY RESTARTS WHAT TO DO WHEN COMPUTER FREQUENTLY RESTARTS.  WHAT ARE THE REASONS FOR ITS PERFORMANCE DEGRADATION?  LET US SEE! CAUSE NO 1 CPU OVERHEAT SOLUTION --> CHECK THE CPU TEMPERATURE FROM BIOS.  IF THE CPU TEMPERATURE IS HIGH, EJECT THE CPU FAN AND CLEAN IT PROPERLY WITH COMPRESSED AIR AND BRUSH.   APPLY THE RIGHT COOLING PASTE WITH A PIECE OF CLOTH. NOW APPLY GOOD QUALITY COOLING PASTE WITH A THERMAL COMPOUND OVER THE PROCESSOR.  ATTACH THE HEAT SINK AND FAN AND CHECK THE TEMPERATURE AGAIN.  IF THE CPU FAN SPEED IS LOW AFTER CLEANING , CLEAN THE FAN WITH ISOPROPHYL ALCOHOL, DIESEL AND WHITE PETROL. NOW ATTACH THE FAN AGAIN CHECK THE FAN SPEED IF IT IS SAME AS BEFORE REPLACE THE FAN. CAUSE NO 2 VIRUS --> IF THE PROBLEM IS RELATED TO VIRUS.  INSTALL A GOOD QUALITY ANTIVIRUS SOFTWARE (AVAST, AVG AND QUICK HEAL)ETC AND SCAN THE SYSTEM. CAUSE NO 3 RECENTLY INSTALLED A SOFTWARE, HARDWARE, DEVICE DRIVER.  DRIVER UPDATE SOLUTION :- ASK THE USER FOR RECENTLY INST

UNDERSTANDING THE COMPUTER REGISTERS.

 REGISTERS AND ITS USES IN COMPUTER WORLD. REGISTERS AND ITS USES IN COMPUTER WORLD. “IN THIS LIFE, ALL WE HAVE IS MEMORY! ” THIS EXCLAMATORY SENTENCE IS USED BY MANY FILM MAKERS IN THEIR DIALOG.  SO DOES IT ACTUALLY MEAN SOMETHING TO THEM?  YES IT DEFINITELY MEANS EVERYTHING TO THEM AND US.  THAT’S WHY THEY SHOW THEM IN THEIR CINEMA (MOVIE, FILM WHATEVER YOU SAY).  MEMORIES MEAN EVERYTHING THAT IS STORED IN OUR BRAIN AFTER WE EXPERIENCE IT AND THEN USE IT AS A LESSON FOR LIFE  OR ENTERTAINMENT PURPOSE. HUMANS AS WELL AS ALL LIVING BEINGS DO THAT.  BUT OUR TOPIC IS  “WHAT ARE REGISTERS? WHY DO COMPUTERS NEED THEM?” SO HERE WE BEGIN. THE DISCRETE ELEMENTS OF INFORMATION IN A DIGITAL COMPUTER MUST HAVE A PHYSICAL EXISTENCE IN SOME INFORMATION STORAGE MEDIUM.  FURTHERMORE, WHEN DISCRETE ELEMENTS  OF INFORMATION ARE REPRESENTED IN BINARY FORM, THE INFORMATION STORAGE MEDIUM MUST CONTAIN BINARY STORAGE ELEMENTS FOR STORING INDIVIDUAL BITS.   A BINARY CELL IS A DEVICE THAT POSSESSES TWO STAB

HOW DO COMPUTERS UNDERSTAND BINARY LOGIC

  HOW DO COMPUTER UNDERSTAND THE BINARY LOGIC?   As we have shown in the previous post  LANGUAGE THAT COMPUTER AS WELL AS HUMAN UNDERSTAND  I am going to dig deep of that topic in this post.  I will try to explain how computer understand the binary logic.   So lets begin.   I am going to write about binary logic, that most of the computer manufacturers and developers use.                  Binary logic deals with variables that take on two discrete values and with operations that assume logical meaning.   The two values the variables take may be called by different names (e.g. true and false, yes and no, etc.), but for our purpose it is convenient to think in terms of bits and assign the values of 1 and 0.     Binary logic is used to describe, in a mathematical way, the manipulation and processing of binary information.   It is particularly suited for the analysis and design of digital systems.   For example, the digital logical circuits of many circuits that perform binary

DIVISIONAL FACTS OF OPERATING SYSTEM

OPERATING SYSTEMS DIVISIONAL FACTS An operating system is a software program that acts as an interface between the user and the hardware of the computer.  It also manages the components of the machine such as processor management, disk resource management, input output files, devices etc. Some of the operating system i am going to show you.  So lets get started User interface :  the user interface allow the user to interact with the machine.  There are two types of user interface given by the user interface developers.  They are as follows 1. Character line user interface such as linux redhat 2. Graphical line user interface such as windows operating system In character line user interface the user have to interact with the computer by giving commands that’s why it is also called as command line interface. In graphical user interface this control is given to the user where the user with mouse or keyboard will control the command or an object kept on the
