Why the temporary registers W and Z are named so i mean we start from A, B, C, D, E then H and L coz H stands for higher bit and L for lower bit of the address pinted by memory pointer.. but wats W and Z for?

Correct Answer: In case of Move A to B it will move whatever the value of A into BIt mean it will move numeric, alphanumeric and alphabatic value In case of COMPUTE B=A it will assign the value of A into B But in case of compute only numeric value will be compute

Correct Answer: Object Repository means not a collection of objects it's a common repository for all the people (testing, developers) for seeing all the data in single login for example QA wants to see 5 testers works then he goes to each person login and see the data It's very difficult job for this we can use Object Repository

Correct Answer: Micro processor is a program-controlled device, which fetches the instruction from memory, decodes and executes the instructions Most Micro Processor are single-chip devices

Correct Answer: In binary representation there are some states that believed to be never occurred due to some particular functionality of a given circuit If zero output is assigned to such states then it is called minimal risk solution as we are resetting the formidable states which could be occurred accidentally Another approach is to assigned a don't care to them so it results in lesser logic and hence is called minimal cost solution

Correct Answer: Yes, single thread module

Correct Answer: Yes so if 8529 gives interrupt then it will be serviced immediately but since INTA pin is left hanging the INSR bit will never be set and so whenever my interrupt occurs depending upon priority it will be serviced also the ISR address for all interrupts will be same ie 0024H Interrupt via trap is nonmaskable, so it will be serviced immediately

Correct Answer: Yes, it can be used, if an accurate clock frequency is not required also the component cost is low compared to LC or Crystal

Correct Answer: RST 45 is called as TRAP

Correct Answer: 3MHz is the maximum clock frequency for 8085

Correct Answer: There are 12 interrupts in 8085
