  please give your perfect definition.
  
  
  our first two questions are ::
  
  
  1) what is a micro controller ?
  
  
  2) what is an Array ?
• 

  Sahithi Pallavi

  My answers are ::
  
  
  1) Micro controller is a chip used in C.P.U.
  
  
  2) Array is a collection of similar data type elements in contigous memory allocation.

  1) Micro controller is a chip used in C.P.U.

  Well that is not correct. YOu are basically talking about the microprocessor.
  A muController is a Microprocessing unit with in-built memory, serial & parallel communication modules, A-to-D converters and a host of other features which make it a standalone computational device.

  hey krishna.
  
  first welcome to our CE.
  
  there is a "project ideas and seminar topics" section is there.
  
  It contains lot of seminar topics given by our CEans. Visit once.
  
  this is not the right place to post your question.

  "Array" is a very general term for a lot of things, from a switching circuit to a solar system.

  3) what is a C.P.U ?
  
  
  4) what is a program ?
• 

  Manish Goyal

  first
  1 Array is heterogeneous collection of related data items...
  2 program is a set of instruction used to accomplish a certain task
• 

  Sahithi Pallavi

  My answer is
  
  4) A program is a set of instructions used to accomplish a specific task with in a finete time.

  1.Micro controller :- A highly integrated chip that contains all the components comprising acontroller.
  2.Array :- An array can be defined as a number of memory locations , each of which can store the same data type and which can be referenced through the same variable name.
  An array is a collective name given to a group of similar quantities.
  3.C.P.U :- C.P.U stands for Central Processing Unit.
  CPU is the brain of the computer where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system.
  4.Program :- A program is a set of instructions that performs a certain task.

  Now here is my question:
  
  What is a "development" ?
•

  #-Link-Snipped-#, development is a specified state of growth or advancement.

  And, my question is what is a markup language?

  A markup language is the one in which you cannot build logic but just the outer design.
  
  A switch can be an example. You can make the physical switch with markup language, but what happens when the switch is pressed has to be done in programming language.

  #-Link-Snipped-# basically, i am a cse student and i dont have a clear idea about latch & flipflop.. if u know the answer for my question please post it..

  Latch and flipflop both stores a bit of data. The only difference between latch and flipflop is that flipflops are clocked (edge triggered) devices while latch is not clocked.
  
  That is, if you add a clock to a latch, it becomes a flipflop..👍

  Boolean Expression
  In computer parlance, a Boolean Expression is an expression that produces a Boolean Value (True or False) when evaluated.
  The expression may be composed of Boolean constants, Boolean variables, Boolean operators and other Boolean functions.

  you nearly guessed it. dry weight is the weight of the vehicle without fluids such as fuel, lubricants, coolants, brake, clutch and power steering oil.

  When process are waiting for locked resources in cyclic manner to complete their task.

  kind of. but i dint mean the thermal expansion and contraction.
  
  What i had in my mind was the slip joints in automobiles present between the gear box and the propeller shaft. this joint allows the propeller to move in and out when the leaf-spring vibrates.

  A square engine is one , where the stroke length(bore depth) and the bore diameter are are equal.
  
  due to which the 2-dimensional cross sectional view of this cylinder bore will look like a sqaure.

  Ceiling rose may be a hook affixed to the ceiling to which various types of decorative things can be suspended or lights too.
  Am I correct?

  Ceiling rose may be a hook affixed to the ceiling to which various types of decorative things can be suspended or lights too.
  Am I correct?

  No it is nothing related to aesthetics.
  
  it is that round electrical box, with a very small hole in its centre, through which electric wires pass.
  
  this box is used as a permanent junction (unlike plug sockets) for , connecting devices like tube lights, chandeliers and fans.

  So let me ask another one. Try giving a non-integrable(indefinite) function. Sorry for deviating from the thread.But even this is more exciting to ponder with.(Do not surf the net for answers please.)

  e^at*cos(sinbt) i guess and some more in partial derivatives are not completely integrable

  Forget partial derivatives.I want a non-integrable(indefinitely) function. I'm thinking whether the function you gave is integrable or not.

  my pal post the answer very eager to learn it

  vinod1993

  There are many.! What you said is right I hope.! So here we go.
  Indefinite: sinx/x,e^-x^2. And the function which cannot be integrated anyway is e^tanx(would be glad if some CEan breaks it).I don't think it can even be integrated with limits on.! Can any CEan devise an answer? So curious here.

  now try this :
  
  what is "bearing area" ?
• 

  Jeffrey Arulraj

  bearing area is region covered by a single fore bearing or back bearing during surveying
  
  think i am right
• 

  zaveri

  Bearing area is the additional area of contact provided by a washer, for the bottom surface of the bolt heads to contact with and thus tighten themselves.

  now try an analytical problem for a change. here you are :
  
  in the case of a three-wheeled vehicle (say an autorickshaw), what is the weight distribution on each wheel ?
• 

  Jeffrey Arulraj

  One third on each wheel
• 

  vinod1993

  I'm just guessing,sorry if I am terribly wrong...😀 More weight distribution on the back wheel and lesser in the front? Because the back wheel guides the front.!

  What is Impedance matching ?
• 

  Abhishek Rawal

  The Zout (Output impedance) of one device "matches" to Zin (Input impedance) of other one to get max. Power transfer, this phenomena is called Impedance matching.
  If Z of source & load will not match, then the transmitted signal is partially reflected back, this results in Power loss(heat loss).
  
  I am very bad in creating a definition using technical terms.Hope i did satisfactory work here.

  Nice job buddy boy
  Another way of putting terms is equating an input and output impedance of adjacent blocks to prevent signal attenuation
