The Compact Disc, or CD for short, is an optical disc used to store digital data. It was originally developed to store and play back sound recordings only, but the format was later adapted for storage of data (CD-ROM). Standard CDs have a diameter of 12 mm (4.7 in) and can hold up to 80 minutes of uncompressed audio or 700 MB (700 × 106 bytes) of data. The encoding material sits atop a thicker substrate (usually polycarbonate) which makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data is stored on the disc with a laser or stamping machine.

Correct Option: B

A flip-flop is a circuit that has two stable states and can be used to store state information. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs. It is the basic storage element in sequential logic. Flip-flops and latches are a fundamental building block of digital electronics systems used in computers, communications, and many other types of systems.

The Indian Institute of Information Technology Allahabad (IIIT-A) was established in 1999, as a center of excellence in Information Technology and allied areas. The mission of IIIT, Allahabad is to be a unique and world class nucleating “Apex Center of Excellence” in the area of Information Technology and Allied Sciences, so as to enhance India’s Technological strength in IT and for become a pace-setting institution for other similar institutes to be established in the future. IIIT seeks to derive its strength from a linkage with sound Indian traditions of centuries past, and sets out to create knowledge-based resources in regional languages.

A floppy disk is a thin magnetic-coated disk contained in a flexible or semi-rigid protective jacket. Data is stored in tracks and sectors. The floppy disks are usually 3.5" in size. However, older floppy disks may be in use; these would be 5.25" in size. Double sided high density 3.5" disks can hold 1.44 Mb of data.
