BOOLEAN ALGEBRA AND LOGIC GATE : Boolean Algebra  "B oolean  algebra is a branch of computer science where we study about the 0 and 1  introdueced  a systmatic treatment of logic and developed for the algebraic system called boolean algebra  it is developed by gerorge boole in 1993     Importent property of boolean algebra   im portanat property of boolean algebra is duality principle    one part may be  obtained from the other if the bianry operator and the identity is interchanged called duality principle  Logic Gates: - logic gates are basic fundamental designe which work on basic logic operations on bainary value .it is a physical sturacture or desigen , or building bloks of digital circuits .it is used in various electronic devices.we can eaisely implemnt boolean function AND ,OR, NOT,  with these type  of gates .  

  dear all today i am going to tell you about operating system as the name suggest operating  system which shows manages with diffrent level of the system, opertaing system is a softaware which manges a computer it is just like a secatery of a manger which keeps and rememebr all the information gives to the computer and tell how to do. . operating system governs all the command related to the operation exp-input output and process means when you start the computer,ROM keeps information  to start the computer and loaded operating system, once operating system is loaded in the computer  it keeps process with application and  between diffrent apps. in one line you can say that when you communicate with computer it provides interface to interact with computer so it is secatery between the user and computer  " operating system is an interface between user and computer " +-----------------------------+ |        User Interface    ...

  Dear all  today i am going to tell you about  memory ,yes memory computer memory . when you have to listen name computer memory  ,fistly strikes in your mind it seems to like my memory  as  we remember the things , yes like as computer keeps thing in computer memory but computer is a machine so something diffrent  so children's we come to our topic computer memory where we keep data , information or store information  it is mainly two types    1.Primary memory primary memory is a memory where ew can strore data temprary it means it is a temprary memory or voltile memory which keeps information till power suply on when you turn off computer your data will lost   ex: RAM, REGISTERS, CACHE Memory  2.Secondary memory secondary memory is a permanent memory where we keep information permanently just like your note book so it is also called  nonvoltile memory    EX:-Hard Disk,pen drive flash drive cd r4om compect...

                                                                                              fig.1 Von Neumann architecture is a  a very simple and  realistic architecture  because it is easy to undersatnd and we can easily understand that how data  and program store  in memory . in the above fig .1   when we input data it stores in memory unit which is also called primary memory   , very beutifully primary  memory store  data and program data mens a,b, c, int i, float g, etc  and command like  move delete etc   from  memory unit   when data and comes to alu which is stand for arthmatic and logic unit  which works fa...

  COMPUTER ORGANIZATION hello students , in this blog we will undersatnd about the computer organization  yes , as the name suggest organization, means organized computer so we access  properly information trough well organised computer hardware and sofatware                               there is one more term is computer architucture but you should not be confused between organization and architucture  because arcticture is a internel fuctioning of computer how it works . now organistion is a hard and soft part physically organised  like all input output part of the computer                                                                           ...
