Solutions

S1.Ans. (a)
Sol. EPROM is generally erased by using ultraviolet rays

S2.Ans. (b)
Sol. DRAM stands for Dynamic Random Access Memory.

S3.Ans. (a)
Sol. BIOS is a set of programs that are hardcoded on a chip to load into ROM at startup. Short for Basic Input/Output System, the BIOS is a ROM chip located on all motherboards that allows you to access and set up your computer system at the most basic level.

S4.Ans.(a)
Sol. A volatile device is a device that stores data temporarily. An example of a volatile device is RAM.

S5.Ans.(b)
Sol. dynamic RAM (DRAM), which stores bits in cells consisting of a capacitor and a transistor, DRAM have to be periodically refreshed.

S6.Ans.(b)
Sol. Virtual Memory is the memory that appears to exist as main storage although most of it is supported by data held in secondary storage, transfer between the two being made automatically as required.

S7.Ans.(a)
Sol. Yottabyte > Zettabyte > Exabyte > Petabyte > Terabyte > Gigabyte > Megabyte > Kilobyte > byte > bit.

S8.Ans.(c)
Sol. A floppy disc was a storage device that has a very small storage capacity of only 1.44 MB. Due to small storage capacity and proneness to frequent damages, floppy discs vanished from the market.

S9.Ans.(d)
Sol. Hard disc is a nonvolatile storage device, as the data that is saved on it is never lost on restart or sudden power break.

S10.Ans (b)
Sol. CD-RW (Compact Disc-Rewritable) is a digital optical disc storage format. A CD-RW disc is a compact disc that can be written, read arbitrarily many times, erased, and written again.

S11.Ans.(d)
Sol. Write through is a storage method in which data is written into the cache and the corresponding main memory location at the same time. The cached data allows for fast retrieval on demand, while the same data in main memory ensures that nothing will get lost if a crash, power failure, or other system disruption occurs.

S12.Ans.(e)
Sol. Most operating Systems support virtual memory, which allocates space on the hard disk to supplement the immediate, functional memory capacity of RAM.

S13.Ans.(d)
Sol. Register is a special high-speed storage area within the CPU where all data must be represented before it can be processed.

S14. Ans.(c)
Sol. RAM-Random Access Memory, ROM- Read Only Memory. RAM (Random Access Memory) and ROM (Read Only Memory) are types of computer memory that provide users with access to information stored on a computer.

S15.Ans.(c)
Sol. Main memory works in conjunction with CPU.
