Difference between mnemonics and hexadecimal representation?
Mnemonics are memory aids that use patterns, phrases, or visualizations to help individuals remember information, often leveraging associations or familiar concepts. In contrast, hexadecimal representation is a numeral system that uses base-16, employing digits 0-9 and letters A-F to represent values, commonly used in computing to simplify binary data. While mnemonics enhance memory retention, hexadecimal provides a concise way to represent and manipulate large numbers or data in programming and digital systems.

What are the difference between opcode and operand?
An opcode is an instruction. An operand is information used by the opcode. Not all opcodes require operands.
How an assembler converts assembly mnemonics to machine language?
Each mnemonic maps directly to a machine instruction code, known as an opcode. Some mnemonics map to more than one opcode, however the instruction's operand types will determine which specific opcode will be generated.
What is the difference between an instruction mnemonic and its opcode?
Mnemonic means memory aid.Instruction mnemonics are easy to remember short alphanumeric strings that stand for op codes.Op codes are numbers that are understood by the computer and command it to perform various operations. They are usually inherently difficult for humans to remember.
What is the difference between Mnemonics and hexadecimal representation?
Mnemonics is a method of remembering things by associascation. Hexadecimal is a number system. 0-9 are as usual and then a(10) b(11) c(12) d(13) e(14) f(15)
What is the difference between operand and opcode?
op code is used as the value of instruction . And operand is address location where the instruction can meet.
What is the difference between LDA and STA instructions?
In the 8085, the LDA instruction loads the accumulator from memory, while the STA instructionstores the accumulator to memory. LDA is a read, while STA is a write. LDA is opcode 3AH, while STA is opcode 32H.
How does microprocessor differentiate between data and instruction code?
i) Instruction code deals only with mnemonics and its corresponding opcode but data code refers to your data like 10h which is always of 8 bits or a particular address say 8080h which is of 16 bits. ii) Data is your input to the instruction but an opcode is native to your machine. iii) Data is user specific instruction while opcode is machine specific instruction iv) You can alter data code but you cannot modify an instruction opcode.
Difference between LDA and STA instruction in 8085?
In the 8085, the LDA instruction loads the accumulator from memory, while the STA instruction stores the accumulator to memory. LDA is a read, while STA is a write. LDA is opcode 3AH, while STA is opcode 32H.
CPU does not distinguish data and operation code explain?
As far as the bus interface is concerned, there is no real difference between data and instructions. Except for the S0 pin, an opcode fetch will look the same as a memory read. There is one extra clock cycle following an opcode fetch, which is used by the CPU to decode and process the opcode, but the bus does not care because there is no sequence initiation with ALE.
How does 8086 differentiate between an opcode and operand?
The 8086 microprocessor differentiates between an opcode and an operand primarily through the instruction format, where the opcode is always specified first, followed by the operands. The opcode indicates the operation to be performed, while the operands represent the data or addresses on which the operation will act. The instruction's length is variable, and the processor uses specific bits in the instruction to determine the types and sizes of operands, allowing it to interpret the instruction correctly. Additionally, the opcode itself can include information about the addressing mode, further aiding in the distinction between opcodes and operands.
Are rhymes one example of mnemonic devises?
Rhymes are one example of mnemonic devices. Other examples include music mnemonics, name mnemonics, word or expression mnemonics, and model mnemonics.
What is the necessity to use opcode fetch cycle for every instruction?
The microprocessor uses an opcode fetch cycle for every instruction because it has to know the opcode in order to execute it, and that is located in memory.
