To unfreeze the mac book pro, there are two ways :
a. <span>Click the apple logo which is at the top
left of the menu bar and then select 'force quit'.
b. Hold down the option,
command, and escape buttons and then select 'force quit'. </span>
If all else fails, best option is to hold down the power button on the keyboard till it shuts down.
Answer:
Inverter is an electronic circuit that is located behind the LCD screen on a laptop.
Explanation:
Inverter is an electronic device that is used to convert DC voltage into AC voltage. This will lead to control the output power that is required to Liquid Crystal display. The Output power is limit up to the requirement of Florescent light that are used in Liquid crystal display to make picture visible.
This Inverter is just behind the LCD in laptop to control the lights on the display of screen.
Answer:
Explanation:
The arithmetic logic unit (ALU) performs mathematical, logical, and decision operations. It can be divided into the arithmetic unit (responsible for addition, subtraction, multiplication and division). And logic unit (responsible for comparing, selecting, matching and merging different data or information). The power and efficiency of the CPU depends on the design of the ALU.
Next up is the control unit (CU) which directs all the processor’s operations. It’s where the CPU reads and interprets requests from memory and transforms them into a series of signals (binary). Then it sends the operation to various parts of the laptop as instructed. The CU calls the ALU to perform the necessary calculations. It also coordinates all input/output devices to transfer or receive instructions.
The main job of the memory unit is to store data or instructions and intermediate results. It’s divided into primary memory and secondary memory to supply data to other units of the CPU. It allows the CPU to perform functions requested by programs like the operating system without having to ask RAM.
Another element of the CPU not depicted in the diagram is transistors. To carry out calculations, binary information (ones and zeros) is stored in these microscopic switches. They control the flow of electricity depending on whether the switch is ON or OFF. Signals turn off and on different combinations of transistors to perform calculations. A very thin silicon chip can contain several hundred million transistors.
Answer:
PRINT "Values for Principal (P), Rate (A) and Time (T)"
INPUT P, A, T
I = P * A * T/100
Amount = P + I
PRINT "Interest: ", I
PRINT "Amount: ", Amount
Explanation:
This prompts the user for values for Principal, Rate and Time
PRINT "Values for Principal (P), Rate (A) and Time (T)"
This gets values for Principal (P), Rate (R) and Time (T)
INPUT P, A, T
This calculates the interest (I)
I = P * A * T/100
This calculates the amount (A)
Amount = P + I
This prints the interest (I)
PRINT "Interest: ", I
This prints the amount (A)
PRINT "Amount: ", Amount
It’s Debug. definition: “identify and remove errors from (computer hardware or software)”.
