4 : Answer is B : I/O bus.
The internal bus, also known as internal data bus, memory bus, system bus or Front- Side-Bus, connects all the internal components of a computer, such as CPU and memory, to the motherboard. internal data buses are also referred to as a local bus, because they are intended to connect to local devices.
5 : Answer is D : average cycles.
In computer architecture, cycles per instruction(aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor's performance: the average number of clock cycles per instruction for a program or program fragment.it is the multiplicatve inverse of instructions per cycle.
6 : Answer is B : opcode.
In computing, an opcode(abbreviated from operation code, also known as instruction syllable, insruction parcel or opstring) is the portion of a machine language instruction that specifies the operation to be performed.
7 : Answer is C : Memory buffer register.
Memory Data Register(also known as the memory buffer register) holds a data value that is being stored to or retrieved from the memory location currently addressed bythe memory address register.
8 :Answer is A : memory address register.
In a computer, the Memory Address Register (MAR) is the CPU register address from which data will be fetched to the CPU or theaddress to which data will be sent and stored. In other words, MAR holds the memory location of data that needs to be accessed.
9 : Answer is F: atransfer of control instruction.
jump statementes can be used to modify the behavior of conditional and iterative statements. jump statements allow you to exit a loop, start the next iterationof a loop, or explicitly transfer program control to a specified location in your program.
