Fetch-Decode-Execute Cycle is the basic operation cycle of a computer. It is the process by which a computer retrieves a program instruction from its memory (fetch), determines what actions the instruction requires (decode), and carries out those actions (execute). It is repeated continuously by the central processing unit, from boot up to when the computer is shut down.

Correct Option: C

Data is organized in a data storage hierarchy of increasingly complex levels: bits, bytes (characters), fields, records, files, and databases. Data are logically organized into: l Bits (characters): - a bit is the smallest unit of data representation (0 or 1); l Byte: a unit of digital information that most commonly consists of 8 bits; l Field: a field consists of a grouping of characters; l Record: record consists of fields, with each field describing an attribute of the entity; l File: a group of related records; l Database: an integrated collection of logically related records or files.

Micro encapsulation is one of the several technologies used in Electronic printing. It is widely used in “carbonless” carbon paper and “scratch-and-sniff” cologne and perfume advertisements in magazines. This technology involves the usage of millions of transparent fluid-filled capsules containing microscopic particles (Chemistry By Steven Zumdahl, Susan Zumdahl, p. 488).
