What is Stack?

Correct Answer: For D latch: always@(enable) q<=d; For D flip flop: always@(opsedge clock) q<=d;

Correct Answer: A blocking assignment is one in which the statements are executed sequentially, ie, first statement is executed and variable is assigned a value then second is executed and so on A non blocking assignment is one in which statements occurs conturrently, only non blocking assignments should be used in sequential circuit eg initial begin a=b; //blocking c<=a; //nonblocking d=c; // blocking end In this example firstly the value of b is assigned to a and this value is assigned to c only after execution of first statement the second and the third statements are executed simultaneously, ie value a ais assigned to c and previous value if c is assigned to d

Correct Answer: Stack pointer is a special purpose 16-bit register in the Microprocessor, which holds the address od the top of the stack

Correct Answer: Sign flag, Zero flag, Auxillary flag, Parity flag, Carry flag

Correct Answer: the powerful cell phones can transmit a signal of 3 watts

Correct Answer: Flag is a flip-flop used to store the information about the status of a processor and the status of the insturction executed most recently A software or hardware mark that signals a particular condition or status A flag is like a switch that can be either on or off The flag said to be set when it is turned on

Correct Answer: compiler is used to translate the high-level language program into machine code at a time It doesn't require special instruction to store in a memory, it stores automatically the execution time is less compared interpreter A compiler is a program that translates a source program written in some high-level programming langualge (such as Java) into machine code for some computer architecture (such as the Inter Pentium archiecture)

Correct Answer: Floating gate avalanche injection MOS (FAMOS) transistor is used in each cell of EPROM

Correct Answer: Cache momory is a small high-speed memory it is used for temporary storage of data & information between the main memory and the CPU(center processing unit) The cache memory is only in RAM Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM AS the microprocessor processes data, it looks in the cache memory and if it finds the data there

Correct Answer: interrupt is a signal send by external device to the processor so as to request the processor to perform a particular work A signal informing a program that an events has occurred when a program receives an interrupt signal, it takes a specified action (which can be to ignore the signal)
