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.

"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.

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.

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).
