This set of Computer Organization and Architecture Multiple Choice Questions & Answers (MCQs) focuses on “Read-Only Memory”.
1. If the transistor gate is closed, then the ROM stores a value of 1.
Explanation: If the gate of the transistor is closed then, the value of zero is stored in the ROM.
2. PROM stands for __________
a) Programmable Read Only Memory
b) Pre-fed Read Only Memory
c) Pre-required Read Only Memory
d) Programmed Read Only Memory
Explanation: It allows the user to program the ROM.
3. The PROM is more effective than ROM chips in regard to _______
b) Memory management
c) Speed of operation
d) Both Cost and Speed of operation
Explanation: The PROM is cheaper than ROM as they can be programmed manually.
4. The difference between the EPROM and ROM circuitry is _____
a) The usage of MOSFET’s over transistors
b) The usage of JFET’s over transistors
c) The usage of an extra transistor
d) None of the mentioned
Explanation: The EPROM uses an extra transistor where the ground connection is there in the ROM chip.
5. The ROM chips are mainly used to store _______
a) System files
b) Root directories
c) Boot files
d) Driver files
Explanation: The ROM chips are used to store boot files required for the system startup.
6. The contents of the EPROM are erased by ________
a) Overcharging the chip
b) Exposing the chip to UV rays
c) Exposing the chip to IR rays
d) Discharging the Chip
Explanation: To erase the contents of the EPROM the chip is exposed to the UV rays, which dissipate the charge on the transistor.
7. The disadvantage of the EPROM chip is _______
a) The high cost factor
b) The low efficiency
c) The low speed of operation
d) The need to remove the chip physically to reprogram it
8. EEPROM stands for Electrically Erasable Programmable Read Only Memory.
Explanation: The disadvantages of the EPROM led to the development of the EEPROM.
9. The disadvantage of the EEPROM is/are ________
a) The requirement of different voltages to read, write and store information
b) The Latency read operation
c) The inefficient memory mapping schemes used
d) All of the mentioned
10. The memory devices which are similar to EEPROM but differ in the cost effectiveness is ______
a) Memory sticks
b) Blue-ray devices
c) Flash memory
Explanation: The flash memory functions similar to the EEPROM but is much cheaper.
11. The only difference between the EEPROM and flash memory is that the latter doesn’t allow bulk data to be written.
Explanation: This is not permitted as the previous contents of the cells will be overwritten.
12. The flash memories find application in ______
a) Super computers
b) Mainframe systems
c) Distributed systems
d) Portable devices
Explanation: The flash memories low power requirement enables them to be used in a wide range of hand held devices.
13. The memory module obtained by placing a number of flash chips for higher memory storage called as _______
c) Flash card
14. The flash memory modules designed to replace the functioning of a hard disk is ______
b) Flash drives
Explanation: The flash drives have been developed to provide faster operation but with lesser space.
15. The reason for the fast operating speeds of the flash drives is
a) The absence of any movable parts
b) The integrated electronic hardware
c) The improved bandwidth connection
d) All of the mentioned
Explanation: Since the flash drives have no movable parts their access and seek times are reasonably reduced.
