B) switcher
C) capacitor
D) resistor

Accepted Answer

An integrated circuit contains transistor which can act as an electronic switch that opens or closes the circuit for electrical charges. Capacitors store electrical energy, resistors oppose the flow of electrical current and switchers do not exist in electronic circuits as an individual component. Therefore, the correct choice is A) transistor.

Question 5

B) switchers
C) capacitors
D) registers

Accepted Answer

Registers are small high-speed storage locations contained by the processor that temporarily hold data and instructions. Indices are used to reference the position of data in an array or list, switchers are devices that allow multiple signals to share a single output, and capacitors store energy in an electric field.

Question 6

The processor relies on which of the following to control the timing of all computer operations?
A) system clock
B) master clock

Accepted Answer

The system clock is a vital component in a computer's architecture, acting as an oscillator and providing the timing signal for all operations. The processor relies on the system clock to synchronize operations between the CPU and system memory, as well as to regulate the speed at which instructions are executed. The master clock and unit clock do not exist in computer architecture, and the control clock is not typically used for timing operations.

Question 7

Which of the following processors is a single chip with two or more separate processor cores?
A) parallel
B) compressed
C) multi-core
D) binary

Accepted Answer

A multi-core processor is a single chip with two or more separate processor cores. This allows for better multitasking and overall performance in a computer system. The other options are not relevant to describing a multi-core processor.

Question 8

Which of the following is measured by the number of ticks per second?
A) temporal rate
B) system rate
C) processor speed
D) clock speed

Accepted Answer

The number of ticks per second is commonly referred to as the clock speed, which measures the rate at which a processor can execute instructions.

Question 9

Which of the following is another term for the system unit?
A) form factor
B) chassis
C) motherboard
D) chip

Accepted Answer

The system unit is often referred to as the chassis, which is the frame that holds the internal components of the computer. It typically includes the power supply, motherboard, and other essential hardware.

Note: A) form factor refers to the physical size and shape of the system unit, C) motherboard refers specifically to the main circuit board that connects all of the computer's components, and D) chip refers to a small, integrated circuit that performs a specific function within the computer.

Question 10

Which of the following is a small piece of semiconducting material, usually silicon, on which integrated circuits are etched?
A) computer plug
B) computer port
C) computer chip
D) computer roster

Accepted Answer

A small piece of semiconducting material on which integrated circuits are etched is known as a computer chip.

Question 11

Which of the following is a register function?
A) storing the location from where an instruction was fetched
B) storing a control while the instruction unit decodes it
C) storing the operand for a calculation
D) storing data while the AXU calculates it

Accepted Answer

The answer of Which of the following is a register...

Question 12

Which kind of tablet positions the case below a keyboard, providing functionality similar to that of a laptop?
A) slate
B) console
C) integrated
D) convertible

Accepted Answer

A convertible tablet has a keyboard base that can be attached or detached, providing the functionality of a laptop when attached and a tablet when detached.

Question 13

The faster the clock speed, the more of these the processor can execute per second. What are they?
A) registers
B) functions
C) arguments
D) instructions

Accepted Answer

The faster the clock speed, the more instructions the processor can execute per second. The other options are not directly related to clock speed.

Question 14

Which of the following is a cache separate from the processor chip on the item shown in the accompanying figure?
A) L1 cache
B) L2 cache
C) L3 cache
