| Assembly Language (Quiz) Size Mismatch Error is a syntax error:False True Unconditional jumpExecute in every condition whether true or false If the condition is true If the condition is false None of the given Bydefault CS is associated withSS BP CX IP Register whose each bit specify a different meaning isAccumulator Register Pointer Register Index register Flag register Which type of Rotation it is "Every bit moves one position to the right and the bit ropped from the right is inserted at the left. This bit is also copied into the carry flag."ROL RCR RCL None of the given Assembly language is not a low level language.True False In JA jump is not taken after a CMP if the unsigned destination is larger than the unsigned source.True False Group of bits processor uses to inform memory which element to read/write is collectively known asControl bus Data bus Address bus RAM Memory to Memory operation is allowedTrue False 90 is the op-code ofDo nothing Add Subtract Multiplication We can not add two base register i.e. (bx bp) or cant use in an instructionTrue False Intel followLittel endian Big endian Both littel endian and big endian None of the given SHL and SAL are sameTrue False Register whose each bit specify a different meaning isAccumulator Register Pointer Register Index register Flag register The first 16-bit processor produced by “Intel” was 8085True False The first 16-bit processor produced by “Intel” was 8085True False The extension of assembly languague file is.doc .com .lst .asm By default CS is associated withSS BP CX IP When a large number is subtracted from a smaller number, a borrow is needed; in this case which flag will be setZF CF SF OF All the addressing mechanisms in iAPX88 return a number called _____________ address.Effective address Physical address Direct address None of the given In direct addressing the memory address given in the instruction isFixed Variable Register Empty Which type of shifting is "Inserts a zero from the left and moves every bit one position to the right and copies the rightmost bit in the carry flag."SHL SAL SAR None of the given mov [1234],ax is an example ofDirect addressing Base register indirect Base index None of the given Registers are also called scratch pad ramTrue False we can not Subtract index register from the base register( bx - si )in assembly languageTrue False Register are storage cellOutside the processor Both inside and outside the processor Inside the processor None of the given By default CS is associated withSS BP CX IP In direct addressing the memory address given in the instruction isFixed Variable Register Empty The basic function of register is toHold the operand Hold the operator Hold both the operator and operand None of the given Instruction Pointer holds the address of thePrevious instruction to be executed Current instruction Next instruction to be executed None of the given Register to Register Operation is not allowedTrue False Address is alway go fromProcessor to memory Memory to processor Memory to memory None of the given CX register mostly use aCounter register Flag register Base register Desination register The jump is taken if the last arithmetic operation changed the sign unexpectedly.JO JNO JNZ JZ In JA jump is not taken after a CMP if the unsigned destination is larger than the unsigned source.True False Which type of rotation it is "The carry flag is inserted from the left, every bit moves one position to the right, and the right most bit is dropped in the carry flag. "RCR ROL RCL ROR Which type of rotation it is "The carry flag is inserted from the left, every bit moves one position to the right, and the right most bit is dropped in the carry flag. "RCR ROL RCL ROR This jump is taken if the last arithmetic operation produced a number in its destination that has even parity , Which jump is takenJP JPE JNP both JP and JPE In direct addressing the memory address given in the instruction is When a large number is subtracted from a smaller number, a borrow is needed; in this case which flag will be set ZF CF SF OF The extension of assembly language file is .doc .com .lst .asm Assembly language is not a low level language. True False The basic function of register is to Hold the operand Hold the operator Hold both the operator and operand None of the given All the addressing mechanisms in iAPX88 return a number called _____________ address. Effective address Physical address Direct address None of the given BP by default associated with CS IP SS SP SHL and SAL are same True False Group of bits processor uses to inform memory which element to read/write is collectively known as Control bus Data bus Address bus RAM | |
