In the decimal or binary notations, the symbol used to represent a digit and the digit’s position in a string determines its ____.
- A.
Sign
- B.
Placement
- C.
Base
- D.
Value
Correct Answer
D. ValueExplanation
The symbol used to represent a digit and its position in a string determines its value. In both decimal and binary notations, the value of a digit is determined by its position within the number and the symbol used to represent it. The position of a digit in a number affects its place value, which in turn determines its overall value within the number. Therefore, the value of a digit is determined by its position and the symbol used to represent it.Rate this question:

____ occurs when the absolute value of a negative exponent is too large to fit in the bits allocated tostore it.
- A.
Rounding
- B.
Rotation
- C.
Overflow
- D.
Underflow
Correct Answer
D. UnderflowExplanation
Underflow occurs when the absolute value of a negative exponent is too large to fit in the bits allocated to store it. This happens when a number becomes too small to be represented accurately in the given number of bits.

____ stores each bit by using a single transistor and capacitor.
- A.
Dynamic ROM
- B.
Static ROM
- C.
Dynamic RAM
- D.
Static RAM
Correct Answer
C. Dynamic RAMExplanation
Dynamic RAM (DRAM) stores each bit by using a single transistor and capacitor. In DRAM, the capacitor holds the charge to represent a bit of information, while the transistor acts as a switch to control the flow of charge in and out of the capacitor. This design allows for high storage density and lower cost compared to other memory technologies. However, DRAM requires constant refreshing of the charge in the capacitors, which can result in slower access times compared to static RAM (SRAM).Rate this question:

As bit transmission speed is increased, the duration of each bit in the signal, known as the ____, decreases.
- A.
Bit time
- B.
Overhead
- C.
Block time
- D.
Modulation time
Correct Answer
A. Bit timeExplanation
As the bit transmission speed increases, the duration of each bit in the signal, known as the bit time, decreases. This means that each bit is transmitted in a shorter amount of time, allowing for more bits to be transmitted within a given time frame. This increase in speed is achieved by reducing the time interval between each bit, resulting in a decrease in the duration of each individual bit.Rate this question:
