MEMORY DEVICES :
The main storage is the primary memory, and data and programs are stored in secondary memory. However, memory is not stored in the CPU, but the CPU would only be a mess of wires without it!
RAM (Random Access Memory) and ROM (Read Only Memory) are examples of primary storage. Secondary Storage Devices: Secondary storage is a memory that is stored external to the computer. ... Hard Disk, CD, DVD, Pen/Flash drive, SSD, etc, are examples of secondary storage.
Thus, Computer storage is of two types: ... RAM (Random Access Memory) and ROM (Read Only Memory) are examples of primary storage.

Write the program of while loop .
Answer:#include<stdio.h>
int main(){
int i=1;
while(i<=10){
printf("%d \n",i);
i++;
}
return 0;
}
Explanation:
This is the program I coded on the while loop.
In this exercise we have to use the knowledge of programming in C code to describe a looping so we have the code.
The code can be found in the attached image.
How to repeat code in C?Repeat commands are a feature that allows a certain piece of code in a program to be repeated a certain number of times. In C there are three repetition commands: while, do-while and for.
So in a simpler way the code is:
#include<stdio.h>
int main(){
int i=1;
while(i<=10){
printf("%d \n",i);
i++;
}
return 0;
}

In the code segment below, assume that the ArrayList object numbers has been properly declared and initialized to contain [0, 2, 4, 5]. for (int k = numbers.size() - 1; k >= 0; k--) { if (numbers.get(k) > k) { System.out.print(k + " "); } } What, if anything, is printed as a result of executing the code segment?
Answer:
Result: C The output that will be printed will be: 3 2 1 If the program is executed, the loop runs in reverse. So it runs from 3 to 0. In the first iteration: at index 3 the corresponding number is 5, so since 5 is greater than present value of k.

Determine the binary encoding for a system that uses two’s complement of the base-10
quantities negative six and six for a digital system where all binary numbers are represented by four bits, one where all numbers are represented by eight bits (one byte).
Answer:
4 bits:
6 = 0110
-6 = 1010
8 bits:
6 = 00000110
-6 = 11111010
Explanation:
2's complement is easier to implement, because it only has one representation of 0 and starts counting backwards from the highest number you can represent with the available bits.
e.g.,
7 = 0111
6 = 0110
5 = 0101
4 = 0100
3 = 0011
2 = 0010
1 = 0001
0 = 0000
-1 = 1111
-2 = 1110
-3 = 1101
-4 = 1100
-5 = 1011
-6 = 1010
For 4 bits:
-6 = 01106 = 1010For 8 bits (1 byte):
-6 = 0000 + 0110 = 000001106 = 1111 + 1010 = 11111010What is binary encoding?Binary encoding can be defined as a standard technique that is designed and developed to convert data in plain text (source alphabets) to a form that is easily used by different operating systems (OS), especially through the use of a binary digit (bit) or two-symbol system.
The two’s complement of base-10.In Computer programming, two's complement of base-10 is generally easier to implement because it has a single representation of 0 only.
Decimal Two’s Complement Decimal Two’s Complement
0 0000 0 0000
1 1111 1111 -1 0000 0001
2 1111 1110 -2 0000 0010
3 1111 1101 -3 0000 0011
4 1111 1100 -4 0000 0100
5 1111 1011 -5 0000 0101
6 1111 1010 -6 0000 0110
7 1111 1001 -7 0000 0111
8 1111 1000 -8 0000 1000
For 4 bits:
-6 = 0110
6 = 1010
For 8 bits (1 byte):
-6 = 0000 + 0110 = 00000110
6 = 1111 + 1010 = 11111010

A. randomizer
B. guess
C. guesser
D. random
By using the radiant method from the random module and need to import in order to use a pseudo-random number in your game.
What is randint method?The randint() method is a method or function in the random python module. It is used to get or return an integer number within a specified range.
To use the method, the module must be imported into the python file with the "import random" statement, then the method is referenced using dot notation and specifying the range of integer numbers. Syntax: random. randint first_number, last_number note that the last number in the range is inclusive in the selection.
Random numbers refers to a set of unbiased numbers formed within a defined set of interval. Random number generation using programming paradigm are done using the random module and not the math module.
Therefore, By using the radiant method from the random module and need to import in order to use a pseudo-random number in your game.
