Test Number 3/95

Q: Components that provide internal storage to the CPU are ______
A. Registers
B. Program Counters
C. Controllers
D. Internal chips
Solution: The Registers are the fast storage units. They are responsible for storing intermediate computational results in the CPU. The registers can be user accessible or inaccessible.
Q: Saving data and instructions to make them readily available is the job of __________
A. Storage Unit
B. Cache Unit
C. Input Unit
D. Output Unit
Solution: The storage unit is responsible for storing the data. It makes the instructions readily available for additional or initial processing whenever required. The cache is a software component that stores data to serve the data requests in future. It can contain the result of some earlier computations.
Q: The two basic types of memory in a computer are ________
A. Primary and major
B. Primary and Secondary
C. Minor and Major
D. Main and virtual
Solution: There are two types of memories in a computer system: The Primary Memory and the Secondary Memory.
The primary memory can be directly accessed by the CPU whereas the secondary memory cannot be directly accessed.
Q: Which of the following is used to hold running program instructions?
A. Primary Storage
B. Virtual Storage
C. Internal Storage
D. Minor Devices
Solution: The primary storage is responsible for holding the data, intermediate results and the results of ongoing processes or jobs. Virtual storage is the main memory storage required for saving a large amount of data for future reference. The other options are invalid.
Q: Which of the following is non-volatile storage?
A. Backup
B. Secondary
C. Primary
D. Cache
Solution: The secondary storage is the non-volatile storage unit because the data is not lost when the power supply is dissipated. Primary memory is the volatile memory.
Q: Which of the following is used in main memory?
A. SRAM
B. DRAM
C. PRAM
D. DDR
Solution: DRAM stands for dynamic random access memory. It is denser than SDRAM (Static) and therefore it is used in the main memory. They are in the form of semiconductor RAMs.
Q: Which of the following are types of ROMs?
A. SROM & DROM
B. PROM & EPROM
C. Only one type there is no further classification
D. PROM & EROM
Solution: There are two types of Read Only Memories: PROM i.e., Programmable ROM & EPROM i.e., Erasable Programmable ROM. When only a small number of ROMs with a particular memory content is needed, PROM is used and in case of EPROM, all the contents of the storage cells must be erased before the write operation.
Q: RAID stands for __________
A. Redundant array of independent disks
B. Redundant array of individual disks
C. Reusable Array of independent disks
D. Reusable array of individual disks
Solution: RAID is a multiple-disk database design which is viewed as a single logical disk by the operating system. Data are distributed across the physical drives of the array. It guarantees the recovery of data in case of data failure.
Q: A non-erasable disk that stores digitized audio information is _____
A. CD
B. CD-ROM
C. DVD-R
D. DVD-RW
Solution: A compact disk stores digitized audio information. The standard system uses 12 cm disks and can record more than 60 minutes of uninterrupted playing game.
Q: The first practical form of Random Access Memory was the __________
A. SSEM
B. Cathode Ray Tube
C. William’s Tube
D. Thomas’s Tube
Solution: The first practical form of RAM was William’s Tube made in 1947. It stored data as electrically charged spots on the face of a Cathode Ray Tube.
