UyI.Identification. Read each question carefully. (1 point each).1. It is also responsible for feeding the software to the right hardware like the keyboard, mouse, screen, etc. 2. It holds the memory address of the last item placed on the stack. 3. It contains the address of an instruction to be executed next. 4. It is another chip that can store data temporarily. 5. It contains the address of a location of main memory from where information has to be fetched for information has to be stored. 6. It is used for managing the program stack during function calls and returns. 7.It is a type of operation that arithmetic operations are performed on the data. 8. It holds the data being accessed or stored in memory. 9. It is a type of operation that the data is transferred from a source to a destination.10. It holds the intermediate results of computations. II. Illustrate what is being asked.11-20. Illustrate the entire procedure of the interaction of a program with hardware.III.Multiple Choice. Choose the best answer and write the corresponding letter and the full word.21. It holds an offset value to be added to a memory address.a. Status Register (SR)b. Memory Buffer (or Data) Register (MBR or MDR)c. Index Register (IX)d. Accumulator (ACC)22. The first ALU operand is always stored into the Accumulator and the second operand is present either in Registers or in the data transfer operation.a. Trueb. False23. It is used to indicate whether an operation was successful, to set and clear flags, and to store error information.a. Status Registerb. Accumulatorc. Stack Pointerd. Instruction Register24. Accumulator is the default address thus after data manipulation the results are stored into the accumulator.a. Trueb. False25. Contents of MBR are directly connected to the ___________.a. Address Busb. Control Busc. Data Busd. Control Unit26. One of the operands is always held by the program counter.a. Trueb. False27. It is used for arithmetic and logical operations.a. Instruction Registerb. ALU Operationc. Program Counterd. Accumulator28. The instruction cycle takes more time because it saves time in instruction fetching from memory.a. Trueb. False29. It contains a word of data to be written to memory or the words most recently read.

It is used to access data structures or arrays.a. Stack Pointerb. Memory Data Registerc. Index Registersd. Accumulator32. When complex expressions are computed, program size increases due to the usage of many long instructions to execute it.a. Trueb. False33. It is used for managing the program stack during function calls and returns.a. Memory Data Register (MDR)b. Stack Pointer (SP)c. Instruction Registerd. Program Counter34. As the number of instructions increases for a program, the execution time increases.a. Trueb. False35. The __________ fetches the next instruction, which is stored in the instruction register.a. Instruction Registerb. Accumulatorc. Program Counterd. Stack Pointer36. Address indicates the type of operation to be performed.a. True b. False37. It holds status information about the processor and the current instruction.a. Stack Pointerb. Accumulatorc. Status Registerd. Memory Data Register38.
