Part of the central processing unit
AveGali [126]

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.

What two devices in a computer should be considered "black boxes," and should never be opened due to risks involving charged cap
NNADVOKAT [17]

The two devices in a computer that should be considered "black boxes," and should never be opened due to risks involving charged capacitors are MONITOR and POWER SUPPLY.

Explanation:

  • Physical contact or close proximity to the open power supply caused a discharge from the capacitor that resulted in an electric shock. Capacitors can discharge current even when not energized because they hold a charge for some time after the power is turned off.
  • To do harm to your body, the voltage across the capacitor's terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common 'rule of thumb' is that DC up to 48 Volt is considered low voltage. So a capacitor charged to a voltage below 48 V is fairly safe.
  • A charged capacitor can be very dangerous, so it's important that you avoid coming into contact with the terminals at all times.

Which is a difference between the systems development life cycle (SDLC) and extreme programming (XP)?
Wittaler [7]

Answer:

the correct answer is "B"

Explanation:

the Systems development life cycle (SDLC) is a complete development process for a new product without giving any chance for alteration or improvement, Whereas,

extreme programming (XP) uses a software programme that is coded to allow for alteration. the product is continously modify until its meet customers satisfaction.

SDLC is seen as and archaic method of product development while XP is a new technology used by most company.

therefore, the SDLC models develops an entire system at once, where as XP uses incremental steps to improves an information system quality.
