Article - The Concepts About Memory in a Computer.


Whats is a computer memory, what it makes? Probably you trough once in lifetime. The memory is a specie of table that reserves the data to CPU processes them. Look for it below:

his is an example about the memory works. The data are saved in memory and used when the machine needs. In the memory, other concept that is need remember is that each memory space has its address, so each data is saved in one address inside the memory.

There’s same concepts of memory, basically they’re twice types, the Volatile and the Constant types. See below what they mean.

  • Volatile Memory – Also called dynamic memory, they’re not allocation constant, it cans be changed. For example: Memory RAM (we’ll see after).
  • Constant Memory – They’re constant, it can’t be changed easy. It works with configuration and once save, it can’t be change without desire’s user. For example: Memory ROM, the setup of settings or the Computer’s BIOS. (We’ll see after).

Memory RAM – it’s a dynamic memory and it can be change all the time that the user is in the computer, it helps the software to works with performance in the machine. It save the data only when the software is being used, when it is closed, then this space is free again.

Memory ROM – it’s a constant memory, that is, it can’t be change all the time. Basically it keep information or settings saved without reserves outside influence, but it can be change only when the user desire, but caution if you want make this, search information. The BIOS is an example, a configuration that is save when the computer is fabricated and configured.

Constant Memory keep data saved in it, ever when not in use. The Hard Disc or HD is other example, it keeps your data save in it for when you need their.

The memory is present in many thing in our life, in the TV’s settings, in your computer, calculators, mobile, printer, etc. Today, it make presence in our lifetime.

So, see this program in C language:

#include <stdio.h>

int main() {
int Number=7;
printf (“%i\n”,Number); //It’ll print the number 7
printf (“%i”,&Number); //It’ll print the address of Number
return 0;
}

Show it in the console:


So, it printed the number 7 and after its address on display. Make a test!

Go on Trying! You’re a winner!
Well, that’s all folks!
See you later with others articles.

Course C Initial 7th – Training with Math

Lesson 7. Now, as promised in previous lesson, we’ll go to make some algorithms to practice all knowledge that we learned up to here. First: Make an algorithm that reserves 3 numbers by user and sum them, after show the result. For this, we first make the structure as showed below. How we can see, this is the basic structure of a software in C language. Now, we’ll create the variables for it: Okay, the variables was created. Now we’ll input the values for them with printf’s and scanf’s how you can see below: Note: always use return 0; in the end function. Now we’ll create a new variable called Result that will be the sum of Num1, Num2 and Num3 how you can see below. After we’ll print Result. That’s finished, we have an algorithm that calculates the sum between 3 numbers. Now, practice this algorithm, write and test yourself, test it change the math operators and joyful. You cou

Course C Initial – 3rd Variables Part. 1

Lesson 3 Part. 1. Hello again! As promised in the previous class, now I speak about variables in C language. First, what’s a variable? The answer is important because it will help us to learn more and use them. Definition: capable of being varied or changed; alterable. (source: www.dictionary.com). That’s the definition that we need! So, there’s some variables types in C language. They’re: Global; Locale; Constant; Volatil e; Inside each one of those cases, we have in resume, 4 type that can be represent in each or all those cases. Below, you’ll can see its names. c har – ‘a’, ‘b’, ‘c’,...; int – 1, 2, 4, 7,...; float – 7.553279, 8.856347,...; double – 9.5896324789632, 10.5885569347799,... ; There’s variations inside each format, but we’ll see in the future. How we can see above, the type data that the variables types represent. Char is for character data, int is for integer, float is for floating point

Course Python For Life 3 – Input Command

As was promised in the previous lesson, now we’ll see the input command in python language, it’s a smaller lesson, next lesson, we’ll see variable’s concepts in Python that’s different of others languages. First step: - I recommend that you use the output command. In python, input command requires a variable. There’s two ways to use this command, they’re: - with print. - without print. Note: In python, you don’t need to use ‘;’ in the end of a line, it works, but it isn’t required. With print: print(‘type any key...’) a = input() Test it yourself! See it in the editor: Run and see what happen. It required that the use type any thing by the keyboard. Below, see it being ran. But there’s other way to do this code, see below: a = input(‘Press any key...’) Test it yourself! Think about it, that’s the way to learn! The appearance is:
