D)transistor

Accepted Answer

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power, controlling the flow of electrons inside a chip.

Question 5

Which of the following is the fourth step of the machine cycle of a computer?
A)The next instruction is fetched from cache or RAM.
B)The instructions are decoded into a form the arithmetic/logic unit or the floating point unit can understand.
C)The data or results are stored in registers or RAM.
D)The instructions are carried out.

Accepted Answer

The fourth step of the machine cycle of a computer involves storing the data or results back into the computer's memory, which can include registers or RAM. This step follows fetching the instruction, decoding it, and executing it.

Question 6

Identify a true statement about RAM (random access memory).
A)It is also known as ROM (Read Only Memory).
B)Data in RAM is erased when the computer is shut off.
C)It is nonvolatile.
D)Having less RAM allows more applications to run at one time in a computer.

Accepted Answer

RAM is volatile memory, meaning that data stored in RAM is lost when the computer is turned off or loses power, distinguishing it from nonvolatile memories like ROM, which retain data without power.

Question 7

Which of the following refers to the versatile bus architecture widely used for connecting peripheral devices?
A)Random Access Memory Bus
B)Register Bus
C)Cache Memory Bus
D)Universal Serial Bus

Accepted Answer

Universal Serial Bus (USB) is the correct answer because it is a widely used bus architecture for connecting peripheral devices such as keyboards, mice, printers, external storage devices, and other USB-compatible devices to a computer.

Question 8

_____ is a special group of very fast memory circuitry, usually built into the CPU, that is used to speed up processing.
A)Flash memory
B)Read-only memory
C)Cache memory
D)Virtual memory

Accepted Answer

Cache memory is a type of high-speed volatile computer memory that provides high-speed data access to the processor and stores frequently used computer programs, applications, and data.

Question 10

Kevin edits a digital photograph. If Kevin uses an image editing program for this purpose, the program will use the arithmetic/logic unit, with help from the _____ when needed, using only arithmetic and logical operations.
A)prefetch unit
B)decode unit
C)bus interface unit
D)floating point unit

Accepted Answer

The floating point unit (FPU) is specifically designed to handle arithmetic and logical operations involving floating-point numbers, which are common in image editing for tasks such as color adjustments, filters, and transformations. The arithmetic/logic unit (ALU) handles basic arithmetic and logical operations, but for operations involving floating-point numbers, the FPU is used to accelerate these processes, providing the necessary computational power for efficient image editing.

Question 11

The part of a CPU core that translates instructions into a form that can be processed by the arithmetic/logic unit (ALU) and floating point unit (FPU) is called the _____.
A)prefetch unit
B)decode unit
C)Universal Serial Bus
D)expansion bus

Accepted Answer

The decode unit is responsible for translating the instructions into a form that can be understood and processed by the arithmetic/logic unit (ALU) and floating point unit (FPU) within a CPU core.

Question 12

The buses in a computer that connect peripheral (typically input and output) devices to the motherboard are often called _____.
A)power buses
B)backside buses
C)expansion buses
D)cache buses

Accepted Answer

Expansion buses are the buses in a computer that connect peripheral devices, such as keyboards and mice, to the motherboard, allowing for the expansion of the computer's capabilities.

Question 13

The _____ allows the core of a computer to communicate with other CPU components, such as the memory controller and other cores.
A)prefetch unit
