  • rambus channel
  • d-link
  • dial-up
  • none of the mentioned
Answer: rambus channel
Explaination:
the special communication link is used to provide the necessary design and required hardware for the transmission.
Q7 | The original design of the RAMBUS required for                   data lines.
  • 4
  • 6
  • 8
  • 9
Answer: 9
Explaination:
out of the 9 data lines, 8 were used for data transmission and the one left was used for parity checking.
Q8 | The RAMBUS requires specially designed memory chips similar to            
  • sram
  • sdram
  • dram
  • ddrram
Answer: dram
Explaination:
the special memory chip should be able to transmit data on both the edges and is called as rdram’s.
Q9 | A RAMBUS which has 18 data lines is called as                 
  • extended rambus
  • direct rambus
  • multiple rambus
  • indirect rambus
Answer: direct rambus
Explaination:
the direct rambus is used to transmit 2 bytes of data at a time.
Q10 | The RDRAM chips assembled into larger memory modules called               
  • rrim
  • dimm
  • simm
  • all of the mentioned
Answer: rrim
Explaination:
none.
Q11 | If the transistor gate is closed, then the ROM stores a value of 1.
  • true
  • false
Answer: false
Explaination:
if the gate of the
Q12 | PROM stands for                       
  • programmable read only memory
  • pre-fed read only memory
  • pre-required read only memory
  • programmed read only memory
Answer: programmable read only memory
Explaination:
it allows the user to program the rom.
Q13 | The PROM is more effective than ROM chips in regard to                 
  • cost
  • memory management
  • speed of operation
  • both cost and speed of operation
Answer: both cost and speed of operation
Explaination:
the prom is cheaper than rom as they can be programmed manually.
Q14 | The difference between the EPROM and ROM circuitry is            
  • the usage of mosfet’s over transistors
  • the usage of jfet’s over transistors
  • the usage of an extra transistor
  • none of the mentioned
Answer: the usage of an extra transistor
Explaination:
the eprom uses an extra transistor where the ground connection is there in the rom chip.
Q15 | The ROM chips are mainly used to store                 
  • system files
  • root directories
  • boot files
  • driver files
Answer: boot files
Explaination:
the rom chips are used to store boot files required for the system startup.
Q16 | The contents of the EPROM are erased by                   
  • overcharging the chip
  • exposing the chip to uv rays
  • exposing the chip to ir rays
  • discharging the chip
Answer: exposing the chip to uv rays
Explaination:
to erase the contents of the eprom the chip is exposed to the uv rays, which dissipate the charge on the transistor.
Q17 | The disadvantage of the EPROM chip is                 
  • the high cost factor
  • the low efficiency
  • the low speed of operation
  • the need to remove the chip physically to reprogram it
Answer: the need to remove the chip physically to reprogram it
Explaination:
none.
Q18 | EEPROM stands for Electrically Erasable Programmable Read Only Memory.
  • true
  • false
Answer: true
Explaination:
the disadvantages of the eprom led to the development of the eeprom.
Q19 | The memory devices which are similar to EEPROM but differ in the cost effectiveness is               
  • memory sticks
  • blue-ray devices
  • flash memory
  • cmos
Answer: flash memory
Explaination:
the flash memory functions similar to the eeprom but is much cheaper.
Q20 | The only difference between the EEPROM and flash memory is that the latter doesn’t allow bulk data to be written.
  • true
  • false
Answer: true
Explaination:
this is not permitted as the previous contents of the cells will be overwritten.
Q21 | The flash memories find application in               
  • super computers
  • mainframe systems
  • distributed systems
  • portable devices
Answer: portable devices
Explaination:
the flash memories low power requirement enables them to be used in a wide range of hand held devices.
