"CD-ROM is a semiconductor memory" is a FALSE statement.

Compact Disc-Read-Only Memory, a type of optical disk capable of storing large amounts of data -- up to 1GB, although the most common size is 650MB (megabytes). A single CD-ROM has the storage capacity of 700 floppy disks, enough memory to store about 300,000 textpages.

Semiconductor memory is a type of semiconductor device tasked with storing data. There are two electronic data storage mediums that we can utilize, magnetic or optical.

Magnetic storage:

* Stores data in magnetic form.

* Affected by magnetic fields.

* Has high storage capacity.

* Doesn't use a laser to read/write data.

* Magnetic storage devices are; Hard disk , Floppy disk, Magnetic tape etc.

Optical storage:

* Stores data optically, uses laser to read/write.

* Not affected by magnetic fields.

* Has less storage than a hard disk.

* Data accessing is high, compared to a floppy disc.

* Optical storage devices are; CD-ROM,CD-R, CD-RW, DVD etc.

There is also volatile memory. This is memory that loses its data once power is cut off, while non-volatile memory retains data even without power.

It rises in the hills of the Chhota Nagpur plateau and joins Hooghly after covering 22000 sq km. Its fury has been brought under control by DVC (Damodar Valley Corporation).

Total value = 4 + 2 + 2 + 3 = 11.

p is pointer to function whose parameter is void and return type is also void. r and q is pointer to function whose parameter is void and return type is int . So they can hold the address of such function.

Sources of the seventeenth century refer to two kinds of peasants –khud-kashta and pahi-kashta. The pahi-kashta were non-resident cultivators who belonged to some other village but cultivated lands elsewhere on a contractual basis. People became pahi-kashta either out of choice –for example, when terms of revenue in a distant village were more favourable –or out of compulsion –for example, forced by economic distress after a famine.
