Group of answer choices.
A. Computing devices translate digital to analog information in order to process the information.
B. Computing devices are electronic.
C. The CPU processes commands.
D. The memory uses binary numbers
Answer:
A. Computing devices translate digital to analog information in order to process the information.
Explanation:
Computing is the process of using computer hardware and software to manage, process and transmit data in order to complete a goal-oriented task.
The true statements about computers are;
I. Computing devices are electronic: the components and parts which makes up a computer system are mainly powered by a power supply unit and motherboard that typically comprises of electronic components such as capacitors, resistors, diodes etc.
II. The CPU processes commands: the central processing unit (CPU) is responsible for converting or transforming the data from an input device into a usable format and sent to the output device.
III. The memory uses binary numbers: computer only understand ones and zeros.
Answer:
Explanation:
The following code is written in Java. It creates the Bug class with the position and direction variables. Then it creates a constructor, move method, turn method, and getPosition method. Finally, a bug object called bugsy is created in the main method, and we move it once to the right, then again to the right, and then we turn it and move it 5 times to the left, printing out the position when it is done moving. Output can be seen in the attached picture below.
class Brainly {
public static void main(String[] args) {
Bug bugsy = new Bug(10);
bugsy.move();
System.out.println("Current bug position: " + bugsy.getPosition());
bugsy.move();
System.out.println("Current bug position: " + bugsy.getPosition());
bugsy.turn();
bugsy.move();
bugsy.move();
bugsy.move();
bugsy.move();
bugsy.move();
System.out.println("Current bug position: " + bugsy.getPosition());
}
}
class Bug {
char direction = 'r';
int position = 0;
public Bug(int initialPosition) {
this.position = initialPosition;
}
public void turn() {
if (this.direction == 'r') {
this.direction = 'l';
} else {
this.direction = 'r';
}
}
public void move() {
if (this.direction == 'r') {
this.position += 1;
} else {
this.position -= 1;
}
}
public int getPosition() {
return this.position;
}
}
Answer:
The transistor density of the hardware which will exist in 2 years time will likely be double the current processing speeds.
Explanation:
The other 3 options are incorrect
Answer:
<u>False</u>
Explanation:
Note, the Rapid Application Development (RAD) software development approaches are noteworthy not for its expanded design details but for <u>its simplicity of the software development process.</u>
In other words, the RAD approaches while taking user preferences into the software development process, focuses on making the software design process more flexible, such as by employing the use of prototypes, and less unnecessary details.
