Computer Memory and Logic Devices Quiz

What is the difference between primary memory and secondary memory in a computer or digital device?

• Primary memory is faster but smaller in capacity while secondary memory is slower but larger in capacity

• Primary memory is non-volatile while secondary memory is volatile

• Primary memory is used for long-term storage while secondary memory is used for short-term storage

• Both a and b

What is the process of saving information in memory called?

• Storing

• Reading

• Writing

• Retrieving

How is data read from SRAM?

• The bitline and its inverse are precharged to 0 before setting WL=1

• The bitline and its inverse are precharged to Vdd before setting WL=1

• The bitline and its inverse are precharged to 0 after setting WL=1

• The bitline and its inverse are precharged to Vdd after setting WL=1

What is the function of the CS (chip select) line in the 4X8 memory block design?

• To enable and disable the whole chip

• To store data in the D-flipflops

• To select a particular memory location

• To select a particular column of D-flipflops

What is the relationship between the address lines A0 and A1 and the selection lines in the 4X8 memory design?

• The address lines and selection lines have no relationship

• The address lines are dependent on the selection lines

• The address lines and selection lines are independent of each other

• The selection lines are dependent on the input given to the address lines

What type of flip flop is used in the 4X8 memory block designed using 2:4 Decoder?

• D flip flop

• T flip flop

• JK flip flop

• SR flip flop

What is a Programmable Logic Device (PLD)?

• A basic electronic device with simple functions

• A reconfigurable electronic device made up of AND gate arrays, OR gate arrays, and interconnection fuses used to implement complex functions

• A device that cannot be programmed to perform different tasks

• A device that does not have the ability to reduce power requirements for the design

What is the purpose of a PROM in electronic devices?

• Store data for advanced memory

• Store complex information

• Store data temporarily

• Store low-level device drivers

How are the settings of each bit in a PROM secured?

• By a fuse

• By a switch

• By a magnet

• By a capacitor

What is the main advantage of using a Programmable Logic Array (PLA) in electronic circuits?

• It allows customization of logic functions by connecting fixed AND gates to programmable OR gates

• It can generate only a limited number of minterms

• It is not flexible in operation

• It is not suitable for implementing a logic function of multiple variables and outputs
