DFD stands for-
- a)data file disk
- b)data flow diagram (correct answer)
- c)disk flat database
- d)disk file database
Answer and explanation
Correct answer: (b) data flow diagram
DFD stands for Data Flow Diagram. It is the structured-analysis diagram that shows how data moves through a system: external entities, processes, data stores and the data flows between them. SWEBOK describes DFDs as diagrams that show data flow among computing elements. They are drawn in levels, starting from a context (Level 0) diagram and breaking each process down in lower levels.
Why the other options are wrong
- (a) data file disk: not a real expansion; a DFD is a diagram, not a storage device.
- (c) disk flat database: invented wording; DFD has nothing to do with flat-file databases.
- (d) disk file database: also invented; it mixes storage terms that do not match the acronym.
Tip: DFD shows the flow of data; a flowchart shows the flow of control.

1 (one) nibble is equal to—
- a)1 bit
- b)2-bit
- c)4-bit (correct answer)
- d)8-bit
Answer and explanation
Correct answer: (c) 4-bit
A nibble is a group of 4 bits, half of an 8-bit byte. Four bits give 2⁴ = 16 patterns (0000 to 1111), so one nibble is exactly one hexadecimal digit (0–F), and a byte is two nibbles: 1001 1010 = 9A₁₆. One BCD digit also fills one nibble.
Why the other options are wrong
- (a) 1 bit: a bit is a single binary digit, the smallest unit; a nibble contains four of them.
- (b) 2-bit: 2 bits give only 2² = 4 patterns, not enough for one hex digit.
- (d) 8-bit: 8 bits make a byte, which is two nibbles.
Tip: bit (1) → nibble (4) → byte (8); one nibble = one hex digit.
