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:
The answer to this question is given below in the explanation section.
Explanation:
Most business applications and websites use and process the credit card for their transaction.
For example, e-commerce website such as ali baba, am a zon, accepting credit card transaction when the customer gets to purchase any product from their stores. Their transactions are processed by in house credit card apps/service. But these apps/services owned by a third party. They just give you API services and related code to integrate the credit card services.
By using their in-house credit card apps/services, they know that user has transferred the money into their account for the purchased product, upon receiving payment confirmation, they then prepare and dispatch the order.
So, the correct answer to this question is:
To process the credit card transactions, they license third-party credit card apps/services backed by the internet merchant who is responsible for handling and managing the money of the business account.
For me the some steps I use not 10 steps sorry are I always go through the slide and think what I am talking about. You have to understand what you are talking about and be clear and persuasive. Never look at the presentation. Memorize key phrases and keep your eyes at your audience. make each of your slides colorful so viewers will look at your actually slide.
Answer:
system software is the set of computer programs that controls and manage the operations of computer hardware.
// making the class
class Counter {
int counter;
int limit;
// Constructor
Counter(int a, int b){
counter = a;
limit = b;
}
// static function to increment
static increment(){
if(counter<limit)
nCounter+=1;
}
// Decrement function
void decrement(){
if(counter>0)
nCounter-=1;
}
int getValue(){
return counter;
}
static int nCounter;
int getNCounters(){
return nCounter;
}
};
// Initializa the static
int Counter::nCounter = 0;
