Question 1

Which of the following has the capability to store the information permanently?
A)ram
B)rom
C)storage cells
D)both ram and rom

Accepted Answer

ROM (Read-Only Memory) is designed to store information permanently, unlike RAM (Random Access Memory) which is volatile and loses its content when power is turned off.

Question 2

ROM has the capability to perform______________          
A)write operation only
B)read operation only
C)both write and read operation
D)erase operation

Accepted Answer

ROM (Read-Only Memory) is designed to perform the read operation only, meaning it can only be read from and not written to. This makes it ideal for storing firmware or permanent software that does not need to be modified.

Question 3

Since, ROM has the capability to read the information only then also it has been designed, why?
A)for controlling purpose
B)for loading purpose
C)for booting purpose
D)for erasing purpose

Accepted Answer

ROM is designed to store the firmware or bootstrap loader; it is essential for the booting process of a computer.

Question 4

The ROM is a______________      
A)sequential circuit
B)combinational circuit
C)magnetic circuit
D)static circuit

Accepted Answer

ROM (Read-Only Memory) is a type of combinational circuit because it provides output based solely on the input address lines, without requiring a clock or sequential logic to generate its data output.

Question 5

ROM is made up of______________      
A)nand and or gates
B)nor and decoder
C)decoder and or gates
D)nand and decoder

Accepted Answer

ROM is made up of decoder and or gates. Decoder is used to select the desired memory location and OR gates are used to combine the outputs of the decoder to produce the desired output.

Question 6

In ROM, each bit is a combination of the address variables is called______________      
A)memory unit
B)storage class
C)data word
D)address

Accepted Answer

The answer of In ROM, each bit is a combination...

Question 7

What is memory decoding?
A)the process of memory ic used in a digital system is overloaded with data
B)the process of memory ic used in a digital system is selected for the range of address assigned
C)the process of memory ic used in a digital system is selected for the range of data assigned
D)the process of memory ic used in a digital system is overloaded with data allocated in memory cell

Accepted Answer

Memory decoding refers to the process by which a memory integrated circuit (IC) in a digital system is selected based on the range of addresses assigned to it. This ensures that the correct memory location is accessed or written to during data operations.

Question 8

Which is not a removable drive?______________    
A)zip
B)hard disk
C)super disk
D)jaz

Accepted Answer

The answer of Which is not a removable drive?______________    
A)zip
B)hard disk
C)super...

Question 9

In ROM, each bit combination that comes out of the output lines is called______________      
A)memory unit
B)storage class
C)data word
D)address

Accepted Answer

In ROM, each bit combination that comes out of the output lines is referred to as a "data word." This term describes the group of bits that are read from memory as a unit.

Question 10

VLSI chip utilizes______________      
A)nmos
B)cmos
C)bjt
D)all of the mentioned

Accepted Answer

VLSI (Very Large Scale Integration) chips utilize a variety of technologies including NMOS (n-type metal-oxide-semiconductor), CMOS (complementary metal-oxide-semiconductor), and BJT (bipolar junction transistor). Each of these technologies has its own advantages and applications within the realm of VLSI design.

Question 11

How many address bits are required to select memory location in Memory decoder?
A)4 kb
B)8 kb
C)12 kb
D)16 kb

Accepted Answer

The answer of How many address bits are required to...

Question 12

How memory expansion is done?
A)by increasing the supply voltage of the memory ics
B)by decreasing the supply voltage of the memory ics
C)by connecting memory ics together
D)by separating memory ics

Accepted Answer

Memory expansion is typically achieved by connecting multiple memory integrated circuits (ICs) together, thereby increasing the total available memory capacity. This can be done through various methods such as using memory banks, modules, or arrays to add more memory to a system.

Question 13

IC 4116 is organised as______________  
A)512 * 4
B)16 * 1
C)32 * 4
D)64 * 2

Accepted Answer

IC 4116 is organized as 32 words each of 4 bits, hence the correct configuration is 32 * 4.

Question 14

PLD contains a large number of______________  
A)flip-flops
B)gates
C)registers
D)all of the mentioned

Accepted Answer

PLD (Programmable Logic Device) contains a large number of flip-flops, gates, and registers, making all of the mentioned options correct. These components are programmable, allowing for the implementation of specific logic functions.

Question 15

How many 1024 * 1 RAM chips are required to construct a 1024 * 8 memory system?
A)4
B)6
C)8
D)12

Accepted Answer

To construct a 1024 * 8 memory system using 1024 * 1 RAM chips, you need 8 such chips, one for each bit in the 8-bit word.

Question 16

How many 16K * 4 RAMs are required to achieve a memory with a capacity of 64K and a word length of 8 bits?
A)2
B)4
C)6
D)8

Accepted Answer

Each 16K * 4 RAM chip provides a capacity of 16K addresses with a word length of 4 bits. To achieve a word length of 8 bits, two chips are needed in parallel. To reach a total memory capacity of 64K with 8-bit words, four sets of these pairs are required, totaling 8 chips.

Question 17

Why antifuses are implemented in a PLD?
A)to protect from high voltage
B)to increase the memory
C)to implement the programmes
D)as a switching devices

Accepted Answer

Antifuses in a Programmable Logic Device (PLD) are used to implement the programs. They are a part of the configuration mechanism that allows the PLD to be programmed by creating permanent connections.
