In a memory hierarchy system, data and programs are first stored in secondary or auxiliary memory. Program and its related data are brought in main memory for execution. What if the size of Memory needed for Program is more than the size of memory? Virtual memory is a idea used in some large computer systems which allow user to construct programs as though a large memory space were available, equal to total of secondary memory. Every address produced by CPU goes through an address mapping from so-called virtual address to a physical address in main memory. Virtual memory is employed to give programmers the illusion that they have a very large memory at their disposal although computer in fact has a relatively small main memory. A Virtual memory system offers a mechanism for translating program-generated addresses in correct main memory locations. This is done dynamically whereas programs are being executed in CPU. The translation or mapping is handled automatically by hardware through a mapping table.
Q. Describe about full adder? Let's take full adder. For this other variable carry from previous bit addition is added let'us call it 'p'. Truth table and K-Map for this is dis
Design a 8 to 1 multiplexer by using the fourvariable function given by F(A, B, C, D) = ∑ m(0,1,3,4,8,9,15). Ans. Design of 8 to 1 Multiplexer: It is a four-variable function a
Suppose we have an array-based list A[0..N - 1] and we want to delete all duplicates. LastPosition is initially N - 1, but gets smaller as elements are deleted. Consider the pseudo
Advantage to depth first search: It just looks like it will be a long period it finds 'DAN' until. This highlights an important drawback for depth first search. It can regular
What is non-repudiation? how can it be achieved in designing e-cash based system?
Write a procedure which divides a 32-bit number by a 16-bit number. The procedure must be general which is it's defined in one module and can be called from another assembly module
Genetic Algorithms: In such a scenario the evolutionary approach to "Artificial Intelligence" is one of the neatest ideas of all. Whether we have tried to mimic the functionin
Q. What do you mean by Manual Assembly? It was an old method which required the programmer to translate every opcode in its numerical machine language representation by search
What are SIMM and DIMM? SIMM are Single In-Line Memory Module. DIMM is Dual In-Line Memory Modules. Such modules are an assembly of various memory chips on a separate small boa
