Second Part Here :- II Part Q.1. Give short notes on various Input and Output Devices. Ans.: The devices which are used to input the data and the programs in the computer are known as “Input Devices‟. These devices convert what we input, into a form that is understandable by a computer. It provides man to machine communication. Some of the I/O devices are explained below: (1) Keyboard : The data and instructions are input by typing on the keyboard. The message typed on the keyboard reaches the memory unit of a computer. It‟s connected to a computer via a cable. Apart from alphabet and numeral keys, it has other function keys for performing different functions. (2) Mouse : It‟s a pointing device. The mouse is rolled over the mouse pad, which in turn controls the movement of the cursor in the screen. We can click, double click or drag the mouse. Most of the mouse‟s have a ball beneath them, which rotates when the mouse in moved. The ball has 2 wheels of the sides, which in turn ...

Q.1. Explain the different types of Memory Modules. Ans.: There are two types of memory modules : (i) SIMM : Single Inline Memory Modules (ii) DIMM : Double Inline Memory Modules These are small printed circuit cards (PCC) on which several DRAMS memory chips are placed. Such cards are plugged into the system board of the computer. The SIMM Circuit cards contain several memory chips with contacts placed on only one edge of this PCC whereas in DIMM, it‟s on both sides of the PCC. Q.2. Explain about the System Clock. Ans.: Every computer has got a system clock. It‟s located in the microprocessor. The clock is design by a piece of quartz crystal. The system clock keeps the computer system coordinated. It‟s an electronic system which keeps oscillating at specified times intervals, between 0 & 1. The speed at which this oscillation takes place is called the cycle of the clock. The time taken to reach from „0‟ to „1‟ and back is called clock cycle the speed of the system cl...

Q.1. What is CISC Microprocessor? Ans.: CISC stands for complex instruction set computer. It was developed by Intel. CISC is a type of design for the computers. CISC based computer will have shorter programs which are made up of symbolic machine language. The number of instructions on a CISC processor is more. Q.2. What is RISC Microprocessor? Ans.: RISC stands for reduced instruction set computer architecture. The properties of this design are : (i) A large number of general purpose registers and use of computers to optimize register usage. (ii) A limited & simple instruction set. (iii) An emphasis on optimizing the instruction pyre line . Q.3. What are the different types of Memory? Ans.: The memory in a computer is made up of semi-conductions. Semi-conduction memories are of two types : (1) RAM : Random Access Memory (2) ROM : Read Only Memory (1) RAM : The Read and write (R/W) memory of a computer is called RAM. The User can write information to it and read...

There are a handful more preprocessor commands which can largely be  ignored by the beginner. They are commonly used in "include" files to make  sure that things are not defined twice. NOTE : ‘true’ has any non zero value in C. ‘false’ is zero.  #undef         This undefines a macro, leaving the name free. #if                 This is followed by some expression on the same line. It allows                       conditional compilation. It is an advanced feature which can be                       used to say: only compile the code between ‘#if’ and ‘#endif’                        if the value following ‘#if’ is true, else leave out that code altogether. This is      D ifferent from not executing code—the code will  n...
