Question

A silicon semiconductor crystal called a chip is a small electronic device consisting of

      the necessary electronic components needed to implement various gates.

      T                                        F

The ____________________ connects the CPU, memory, and all other internal

      components.

      A). backplane bus

      B). I/O bus

    C). expansion bus    The instruction set architecture of a machine does not take into consideration the

      format of an instruction.T                                        F. Among other things, assembler directives can ____________________________.A). determine the next action after numeric overflow B). distinguish a value as hexadecimal or decimal C). invoke interrupt service routines D). control conditional assembly using macro instructions

Answer 1

1.) The single semiconductor crystal refers to the chips that are made of semiconductor material having various properties used in many electronic components. These can be operated at very low voltage. Because of directional flow of current properties these can be used in gates also.

Hence, the statement bos TRUE.

2) The backplane bus provides connection between the processor of CPU, the memory and the peripherals attached to the computer.

The I/O buses provides connection between the processor to the input/ output devices.

Expansion bus mainly connects the devices to the motherboard.

Hence, correct answer is A) backplane bus

3) The instruction set architecture which is also known as computer architecture. It tells the processor of computer about what to do by sending a set of commands to the processor. It considers the size, location and format of the instructions.

Hence, the statement is False.

4) Most of the program organization is performed by the assembler directive. This helps in getting machine level language codes from assembly level language by providing the assembler with the required information. It also helps in checking whether a value is in hexadecimal or decimal.

Hence, the answer is B) distinguish a value as hexadecimal or decimal.
