Even though the terms operating memory and short-term memory are frequently used interchangeably, some theorists contend that the two memory types are distinct from one another because working memory permits the manipulation of information.
What system storage working memory to function properly?In contrast to long-term memory, which stores a large amount of knowledge over a lifetime, working memory is the little amount of information that may be kept in mind and used to carry out cognitive tasks. One of the most often used concepts in psychology is working memory.
Working memory is the short-term storage of information, in contrast to long-term memory, which accumulates a huge quantity of information throughout a lifetime. That has been stored, while short-term memory only refers to the temporary storing of information.
Therefore,She needs to check the storage on her computer. She needs to check the things the application needs in order to determine whether she can obtain it.

in python Simple geometry can compute the height of an object from the object's shadow length and shadow angle using the formula: tan(angleElevation) = treeHeight / shadowLength. Given the shadow length and angle of elevation, compute the tree height.
Sample output with inputs: 0.4 17.5
Tree height: 7.398881327917831
Answers
Answer:
import math
angle = float(input('Enter Angle: '))
shadowLength = float5(input('Enter Shadow Length: '))
tree_height = math.tan(angle)*shadowLength
print('Tree Height = {}'.format(tree_height))
Explanation:
From the equation given, the first step is to derive the equation for calculating the Tree Height.
In order to calculate the tangent of an angle, the math module has to be imported. math module allows the program to perform advanced math operations.
The program then prompts the user to input values for angle and shadow length.
The inputted values are converted to floats and used in the equation that was derived for Tree height.
Three height is evaluated and the result is printed to the screen

Assume that x, y, and z are int variables. Write a statement using the conditional operator (? :) that compares the values of the variables x and y. The value of the larger of the two variables should be assigned to z.
Answers
The statement using the conditional operator (? :) that compares the values of the variables x and y will be:
public class Main {
public static void main(String[] args) {
int x = 10;
int y = 20;
int z = (x > y) ? x : y;
System.out.println("z = " + z);
}
}
How to illustrate the information?The ternary conditional operator (?:) has three operands and accepts them all. A boolean expression that can be evaluated as true or false makes up the first operand. The second operand is executed if the boolean statement evaluates to true. The third operand is executed if the boolean expression returns false.
It should be noted that because 10 is not greater than 20, the boolean statement (x > y) in this program evaluates to false. As a result, the third operand (y) is executed, and z is given the value of y (20).

A network switch transmits data packets from one computer network to another computer network.
What is a network switch?A network switch connects devices in a network (such as computers, printers, and wireless access points) and allows them to 'talk' by exchanging data packets.
Switches can be both physical hardware devices that manage physical networks and software-based virtual devices.
A router is significantly more advanced and sophisticated than a switch. They can perform Network Address Translation (NAT), make faster routing decisions, and use routing algorithms to route data across large networks.
Routers connect multiple LANs, whereas switches operate within a single LAN.
A network switch connects and transmits data packets to and from local area network devices (LAN).
Thus, the answer is network switch.
