C [ ]) EPROM
D [ ]) EEPROM
8) A field programmable ROM is called
A [ ]) MROM
B [v]) PROM

10) A combinational PLD with a programmable AND array and a fixed OR
array is called a
A [ ]) PLD
B [ ]) PROM

D [ ]) PLA

 


11) A combinational PLD with a programmable AND array and a
programmable OR array is called a


A [ ]) PLD
B [ ]) PROM
C [ ]) PAL
D [v]) PLA
12) A mask programmed ROM is
A [v]) programmed at the time of fabrication
B [ ]) programmed by the user
C [ ]) erasable and programmable
D [ ]) erasable electrically
13) The length of bus cycle in 8086/8088 is four clock cycles, T1,
T2, T3, T4 and an indeterminate number of wait state clock cycles denoted by
Tw. The wait states are always inserted between
A [ ]) T1 & T2
B [ ]) T2 & T3
C [v]) T3 & T4
D [ ]) T4 & T1
14) Which one of the following
circuits transmits two messages simultaneously in one direction
A [ ]) Duplex
B [v]) Diplex
C [ ]) Simplex
D [ ]) Quadruplex
15) The program counter in a 8085 micro-processor is a 16-bit
register, because
A [ ]) It counts 16-bits at a time
B [v]) There are 16 address lines
C [ ]) It facilitates the user storing 16-bit data temporarily
D [ ]) It has to fetch two 8-bit data at a time

16) A microprocessor is ALU
 
A [ ]) and control unit on a single chip.
B [ ]) and memory on a single chip.
C [ ]) register unit and I/O device on a single chip.
D [v]) register unit and control unit on a single chip.

17) Inintel 8085A microprocessor ALE signal is made high to

A [v]) Enable the data bus to be used as low order address bus

B [ ]) To latch data D0-D7 from data bus
C [ ]) To disable data bus
D [ ]) To achieve all the functions listed above
18) Output of the assembler in machine codes is referred to as
A [v]) Object program

B [ ]) Source program
C [ ]) Macroinstruction
D [ ]) Symbolic addressing
19) Which of the following statements for intel 8085 is correct?
A [ ]) Program Counter (PC) specifies the address of the
instruction last executed B [ ]) Program Counter (PC) specifies the address of
the instruction last executed C [v]) PC specifies the address of the
instruction being executed
D [ ]) PC specifies the number of instructions executed so far
20) A good assembly language programmer should use general purpose
registers rather than memory in maximum possible ways for data processing. This
is because:
A [ ]) Data processing with registers is easier than with memory
B [ ]) Data processing with memory requires more instructions
in the program than 
that  with registers
C [ ]) Of limited set of instructions for data processing with
memory

D [v])  Data processing with
registers takes fewer cycles than that with memory
