Is the address bus unidirectional?
Added on Tue, Dec 15, 2009
The address bus is unidirectional because the address information is always given by the Micro Processor to address a memory location of an input / output devices. Read More
What is the difference between primary & secondary storage device?
Added on Tue, Dec 15, 2009
In primary storage device the storage capacity is limited. It has a volatile memory. In secondary storage device the storage capacity is larger. It is a nonvolatile memory. Primary devices are: RAM / ROM. Secondary devices are: Floppy disc / Hard... Read More

What are the static and dynamic hazards in logic circuits?
Added on Tue, Dec 15, 2009
If for a short period of time circuits goes to some different logic level then it is supposed to have then it is called static hazard.e.g. If the final logic value of output of a given circuit becomes one even if it is supposed to be zero then it is... Read More
What is meant by LATCH?
Added on Tue, Dec 15, 2009
Latch is a D- type flip-flop used as a temporary storage device controlled by a timing signal, which can store 0 or 1. The primary function of a Latch is data storage. It is used in output devices such as LED, to hold the data for display. Read More
What is interrupt? -
Added on Tue, Dec 15, 2009
Interrupt is a signal send by external device to the processor so as to request the processor to perform a particular work. Read More
Can ROM be used as stack?
Added on Tue, Dec 15, 2009
# ROM cannot be used as stack because it is not possible to write to ROM. # What is NV-RAM? - Nonvolatile Read Write Memory, also called Flash memory. It is also know as shadow RAM. Read More
What is a compiler?
Added on Tue, Dec 15, 2009
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 to Interpreter. Read More
What is the disadvantage of microprocessor?
Added on Tue, Dec 15, 2009
It has limitations on the size of data. Most Microprocessor does not support floating-point operations. Read More
What is interrupt?
Added on Tue, Dec 15, 2009
Interrupt is a signal send by external device to the processor so as to request the processor to perform a particular work. Read More
Which transistor is used in each cell of EPROM?
Added on Tue, Dec 15, 2009
Floating ?gate Avalanche Injection MOS (FAMOS) transistor is used in each cell of EPROM. Read More
Give examples for 8 / 16 / 32 bit Microprocessor?
Added on Tue, Dec 15, 2009
8-bit Processor - 8085 / Z80 / 6800; 16-bit Processor - 8086 / 68000 / Z8000; 32-bit Processor - 80386 / 80486. Read More
What is 1st / 2nd / 3rd / 4th generation processor?
Added on Tue, Dec 15, 2009
The processor made of PMOS / NMOS / HMOS / HCMOS technology is called 1st / 2nd / 3rd / 4th generation processor, and it is made up of 4 / 8 / 16 / 32 bits. Read More
Which processor structure is pipelined?
Added on Tue, Dec 15, 2009
# All x86 processors have pipelined structure. # What is flag? - Flag is a flip-flop used to store the information about the status of a processor and the status of the instruction executed most recently Read More
What is flag?
Added on Tue, Dec 15, 2009
Flag is a flip-flop used to store the information about the status of a processor and the status of the instruction executed most recently Read More

Added on Tue, Dec 15, 2009
For D Latch:always@(enable)q<=d; For D flip flop:always@(posedge clock)q<=d; Read More
What is cache memory?
Added on Tue, Dec 15, 2009
Cache memory 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). Thecache memory is only in RAM. Read More
What is NV-RAM?

What would happen if we have odd numbers ofinverters in feedback and also for even numbers of inverters.
Added on Tue, Dec 15, 2009
The odd numbers of inverters behaves as oscillator and can be used for clock generation. The even number of inverters can be used for memory purpose. Read More
Difference between static and dynamic RAM?
Added on Tue, Dec 15, 2009
Static RAM: No refreshing, 6 to 8 MOS transistors are required to form one memory cell, Information stored as voltage level in a flip flop. Dynamic RAM: Refreshed periodically, 3 to 4 transistors are required to form one memory cell, Information is... Read More
Is the data bus is Bi-directional?
Added on Tue, Dec 15, 2009
The data bus is Bi-directional because the same bus is used for transfer of data between Micro Processor and memory or input / output devices in both the direction. Read More
