3D(base 16) = 3(0011) D(1101) = 00111101(base 2). Option A (111101) is 3D(base 16) if leading zeros are ignored.

To convert octal 143 to hexadecimal, first convert to binary: 1 is 001, 4 is 100, 3 is 011. Grouping 001100011 into 4-bit segments from the right gives 0110 (6) and 0011 (3), resulting in 63 in base 16.

Octal 56 is 101 110 in binary. Grouping into 4-bit segments from the right gives 0010 (2) and 1110 (E), resulting in 2E in base 16.

Correct Answer: 5E₁₆ 
Since in octal, the digits are grouped into 3's, 

(136)₈ = 1 101 110

To convert into hexadecimal, we need to group them in 4's, starting from LSB.

Hence,

0101 1110, which is (5E)₁₆

47 octal is 39 decimal, and 52 octal is 42 decimal. 39 * 42 = 1638 decimal. 1638 decimal converted to octal is 3146.

AHPL stands for A Hardware Programming Language, which is a hardware description language used for describing digital systems.

In flowcharts, arithmetic operations and data manipulations are represented by rectangular processing symbols.

A 'Clear' input is a standard control signal in digital logic circuits used to reset the state of a flip-flop or register to zero.

A flowchart is a visual representation of a process or algorithm, showing the steps as boxes and their order via connecting arrows.

BCPL (Basic Combined Programming Language) was designed to facilitate structured programming and served as the precursor to B and C.

Convolutional codes are a type of error-correcting code in which each m-bit information symbol is transformed into an n-bit symbol, where the transformation depends on the current and previous input bits.

A burster is a mechanical device used in data processing to separate continuous fan-folded paper into individual sheets.

The data bus is the set of lines responsible for carrying the actual data between the CPU, memory, and I/O devices.

A master tape is a magnetic tape containing the primary data or program files that are read during processing without being modified.

The 8421 code is the standard Binary Coded Decimal (BCD) system where each decimal digit is represented by four bits with weights 8, 4, 2, and 1.

Cross-coupling is the technique of connecting the output of one logic gate to the input of another to create feedback, which is the fundamental mechanism for building flip-flops.

A transceiver is a device that combines both a transmitter and a receiver in a single unit, allowing it to both send and receive data.
