ELECTRICITY AND ELECTRONICS ACCORDING TO COMPUTER SCIENTIST

  FUNDAMENTALS OF ELECTRICITY AND ELECTRONICS IT WAS DISCOVERED CENTURIES AGO THAT CERTAIN TYPES OF MATERIALS WOULD MYSTERIOUSLY ATTRACT ONE ANOTHER AFTER BEING RUBBED TOGETHER.   FOR EXAMPLE : AFTER RUBBING A PIECE OF SILK AGAINST PIECE OF GLASS, THE SILK AND GLASS WOULD TEND TO STICK TOGETHER. INDEED, THERE WAS AN ATTRACTIVE FORCE THAT COULD BE DEMONSTRATED EVEN WHEN THE TWO MATERIALS ARE SEPARATED .    GLASS AND SILK AREN'T THE ONLY MATERIALS KNOWN TO BEHAVE LIKE THIS.   ANYONE WHO HAS EVER BRUSHED UP AGAINST A LATEX BALLOON ONLY TO FIND THAT IT TRIES TO STICK TO THEM HAS EXPERIENCED THE SAME PHENOMENON.   PARAFFIN WAX AND WOOL CLOTH ARE ANOTHER PAIR OF MATERIALS EARLY EXPERIMETERS RECOGNIZED AS MANIFESTING ATTRACTIVE FORES AFTER BEING RUBBED TOGETHER.   THIS PHENOMENON BECAME EVEN MORE INTERESTING WHEN IT WAS DISCOVERED THAT IDENTICAL MATERIALS, AFTER HAVING BEEN RUBBED WITH SILK WAS EXPOSED TO A PIECE OF WAX RUBBED WITH WOOL,   THE TWO MATERIALS WOULD ATTRACT ONE ANOTH

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

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

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

CHIPSETS OF COMPUTERS.

A CHIPSET IS A COLLECTION OF CHIP OR CIRCUITS THAT PERFORM INTERFACE AND PERIPHERAL FUNCTION FOR THE PROCESSOR.   THIS COLLECTION OF CHIPS IS USUALLY THE CIRCUITS THAT PROVIDES INTERFACES FOR MEMORY EXPANSION CARDS AND ONBOARD PERIPHERALS AND GENERALLY DICTATES HOW A MOTHERBOARD WILL COMMUNICATE WITH THE INSTALLED PERIPHERALS. CHIPSET ARE USUALLY GIVEN A NAME AND MODEL NUMBER BY THE ORIGINAL MANUFACTURER AND MODEL ALSO TELL YOU THAT YOUR PARTICULAR CHIPSET HAVE A CERTAIN SET OF FEATURES EG TYPE OF RAM SUPPORTED TYPE AND BRAND OF ONBOARD AND SO ON. CHIPSETS CAN BE MADE UP ONE OR MORE INTEGRATED CIRCUIT CHIPS.   INTEL BASED MOTHER BOARDS TYPICALLY USE TWO CHIPS.   THE FUNCTION OF CHIPSETS CAN BE DIVIDED INTO TWO MAJOR FUNCTIONAL GROUPS CALLED NORTH BRIDGE AND SOUTH BRIDGE. NOW I AM GOING TO SHOW YOU SOME OF THE BASIC CHIPSET IN COMPUTERS AND WIDELY USED CHIPSETS USED IN MODERN COMPUTERS .   THEIR NAMES AS 1) NORTH BRIDGE 2) SOUTH BRIDGE SO LET US BEGIN IN OUR LITTLE JO

SUMMARY OF MEMORY

RAM PROPERTIES Friends in the last post i tried to explain the different types of ram as well as given the details of its similarities now i am going to show you how the properties of ram can be judged . SO LET US BEGIN. SINGLE SIDED VS DOUBLE SIDED DIMMS or DUAL INLINE MEMORY MODULE whatever you call are often referred to as single chip or double sided to describe whether the chips are located on one or both of the modules printed circuit board . However these terms may cause confusion or distract you from the topic, as the physical layout of the chips does not necessarily relate to how they are logically organized or accessed in whatever terms you are told. ERROR CORECTING CODE MEMORY (ECC MEMORY) An ERROR CORRECTING CODE (or ECC) whatever general public says  could be a   kind of  computer data storage  which will  detect  and proper  the more common  types of  internal data corruption in simple words with firmness and boldness. Most computers or workstati
