FUNDAMENTALS OF COMPUTER:A SAFETY AND CONTROL

  FUNDAMENTALS OF COMPUTER:A SAFETY AND CONTROL WE ALL HAVE THE GUT FEELING OF SAFETY AND CONTROL FOR OUR FAMILY AND BELONGINGS.   SO WE KEEP THEM INFORMED WITH THE IMPEDIMENT DANGERS LURKING IN THE ENVIRONMENT. THIS IS TRUE FOR COMPUTERS ALSO. SO I AM GOING TO SAY ABOUT COMPUTER CONTROL USAGE SUCH AS BACK UP AND RESTORE AND PARENTAL CONTROL AND SOFTWARE LOCKER OF WINDOWS 7.   SO LET US BEGIN. I AM GOING TO SHOW YOU THE STEPS FOR BACK UP AND RESTORE, SOFTWARE CONTROL AND PARENTAL CONTROL.   WE START WITH BACKUP AND RESTORE…. STEP 1 WE FIRST SEE HOW TO BACKUP INFORMATION   GO TO CONTROL PANEL à SYSTEM AND SECURITY à BACK UP AND RESTORE START à ALL PROGRAMS à MAINTENANCE à BACKUP AND RESTORE à SETUP BACKUP à SELECT WHERE YOU WANT TO SAVE YOUR BACKUP à SECOND HARD DISK (SELECT)   à NEXT à SELECT LET ME CHOOSE à NEXT à SELECT THE DRIVE OR FOLDERS WHICH YOU WANT TO TAKE BACKUP à NEXT à CLICK ON CHANGE SCHEDULE à SELECT YOUR BACKUP SCHEDULE DAILY, WEEKLY OR M

FATIGUE PREVENTION IN COMPUTERS

  FATIGUE PREVENTION IN COMPUTERS! MANY TIMES WE WANT TO LOCK APPLICATIONS AND RESTRICT MEMORY IN OUR COMPUTERS TO PREVENT OVERLY USE OF OUR COMPUTERS IN ANY WRONG WORK.   THIS IS THE REASON WHY WE LOCK COMPUTER OR PROVIDE SPECIAL PERSMISSIONS TO THE USER OF A SINGLE MACHINE.   IF IT IS USED BY MANY USERS IN ANY TIME PERIOD.     SO LETS BEGIN OUR TOPIC…. HOW TO LOCK APPS FOR PREVENTION OF COMPUTER FATIGUE.   I WILL SHOW YOU THE STEPS TO DO THE WORK.   GO TO RUN à WRITE GPEDIT.MSC à UNDER COMPUTER CONFIGURATION EXPAND WINDOW SETTINGS à EXPAND SECURITY SETTINGS à EXPAND APPLICATION   CONTROL POLICIES   à SELECT APPLOCKER à EXECUTABLE RULES à CLICK ON EXECUTABLE RULES à RIGHT CLICK ON THE BLANK SPACE à CREATE NEW RULE à NEXT à SELECT DENY à CLICK ON SELECT BUTTON à TYPE THE USERNAME à CLICK CHECK NAMES   à OK à NEXT à SELECT PATH à NEXT à CLICK ON BROWSE à GO TO C: DRIVE \ à WINDOWS FOLDERS à SYSTEM 32 FOLDER à NOTEPAD à NEXT à NEXT à CREATE à YES   STEP 2 GO TO RUN

RULES OF LOGIC ---> INTERNET PROTOCOL

 RULES OF LOGIC---->INTERNET PROTOCOL FRIENDS, TODAY I AM GOING TO DISCUSS SOMETHING ABOUT IP ADDRESSING.  IP IS A LOGICAL ADDRESS FULLFORM INTERNET PROTOCOL.  IT PROVIDES LOGICAL ADDRESS TO NETWORKING DEVICES.   THESE ADDRESSES ARE USED TO DEFINE SOURCE AND DESTINATION OF DATA PACKETS IP HAS TWO VERSIONS 1. IP VERSION 4 2. IP VERSION 6 IP VERSION 4 IT IS 32 BIT ADDRESS WRITTEN IN DECIMAL NUMBER  FORMAT  192.168.1.1 THE NUMBERS IN THE DIGITS LIKE 192.68.1.1 HERE EVERY NUMBER BEFORE THE DOT IS AN OCTET. HERE IT IS SHOWN THAT EACH DIGIT IS PRECEDED BY DOT IS AN NUMBER BELONGING TO AN OCTET LIKE FIRST OCTET, SECOND OCTET , THIRD OCTET AND FOURTH OCTET. EACH OCTET IS AN NUMBER IN BINARY FORM WRITTEN IN 2^8=256 BINARY FORM HERE THE DIGIT SHOWS THAT A VARIABLE IS IN THE BY POWER OF 2, HERE I WANT TO SAY THAT AS COMPUTER UNDERSTANDS BINARY DIGIT IN WHICH THE VARIABLES ARE 0 AND 1.  AS THE COMPUTER UNDERSTANDS BINARY DIGIT SO IT HAS ONLY 2 VALUES. HENCE THE POWER IS WRITTEN IN 2. SO THE

EXPANSION SLOTS IN MOTHERBOARD

EXPANSION SLOTS IN MOTHERBOARD  Friends today i am going to share my knowledge and understanding of the expansion slots. So lets begin with our topic. Expansion slots are used to provide additional properties for carrying the computation task such as additional video, audio and sound, advanced graphics and Ethernet.   So lets begin with our knowledge hunting. I will start by AGP expansion slots. AGP AGP stands for ACCELARATED GRAPHICS PORT.  AGP was introduced with high speed 3D graphics display in 1996.  It is used for older graphics card types which is discontinued by PCI EX16 graphics port in 2005.   These were kernel version of AGP most of the brand in 1.5 volt DC.  AGP 1x channel and 66MHZ clock speed resulting a data table of 266 MBPS.   AGP 2x, 4x ,8x specification multiply MHZ clock to produce increase throughput. AGP 8x produces effective clock frequency of 533 MHZ resulting a throughput of 2 GBPS (2133MHZ) resulting a throughput of over a 32 bit channel. PCI PCI  stands for P

FORMATS OF FILESYSTEM IN COMPUTER TECHNOLOGY

FILE SYSTEM AND FORMATING In this post i am going to teach you about various types of file system and formating used in computers. So lets start. The file system dictates how information is organized on the disk.   For example, the file system determines hjow large the allocation unit, or storage unit, the file is.   The following sections introduce the different file systems available and the os’ s that support them. The FAT FILE SYSTEM – the file allocation table (fat) file system has been the most popular file system up until the last few years.   The file system is designed for the small disk and simple folder structures.   it resides in the beginning of the system. It keeps two copies of the data in its table as back up so that if any copies become corrupted it can cure that corruption.   The file allocation table along with the root folder should be kept on fixed position so that boot files can be perfectly located.   The file allocation table (fat)

MATHEMATICS AND COMPUTER SCIENCE RELATIONSHIP

MATHEMATICS AND COMPUTER SCIENCE RELATIONSHIP. In today’s world mathematics is a must learned subject .   In all the inventions and discovery , the main reason for their success of the practical’s are due to mathematics.   So in order to make a career in today’s world require mathematics.   But this Is blog of computers science and information technology, then why should we read mathematics so it requires mathematics to understand the reason behind such technology.   So I am going to write something about mathematics for its uses and technology in the computer world. One of the main aims of logic is to provide rules by which one can determine whether any particular argument or reasoning is valid (correct) Logic is concerned with all kinds of reasoning whether they be legal arguments or mathematical proofs or conclusions in a scientific theory based upon a set of hypothesis.   Because of the diversity of their application these rules are called rules of inference,

OPERATING SYSTEM- AN INTERFACE?

ALL ABOUT OPERATING SYSTEM An operating system is 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. The operating system can be classified on various parameters. In this section we will learn the classification of the operating system based on the number of user and the number of task performed by operating system that run simultaneously on the computer. So lets begin CLASSIFICATION BASED ON THE NUMBER OF USER Based on the number of people accessing the computer, the operating system can be classified   namely in two types namely single user or multi user.   As shown in list below SINGLE USER :-   in this type of operating system only one users can access the resources of the operating system at a time.   Example of single user include dos and microsoft windows MULTI USER :-   in t
