32-Bit vs 64-Bit Operating System



This has really been confusing to some people choosing between 32-bit and 64-bit systems. Head over to any operating system’s website, you will be given a choice to download either versions of the same operating system. So what is the difference? Why do we have two different versions of the same OS? Let us solve this mystery here, once and for all.

So currently you might get to see either a 32-bit or 64-bit operating system. There is absolutely no difference in both of these systems, they are 100% alike with all the same features and applications. Now you might be wondering which one to choose. Well, the answer is pretty simple.

Depens On Processor
The type of operating system you install depends on the type of processor you have. Currently, there are 2 major types of processors available, 32-bit and 64-bit processors. A 64-bit processor can run both 32 and 64-bit operating systems, however, a 32-bit processor can only run a 32-bit operating systems. 

 Difference between 32-bit & 64-bit

 The difference is that a 32-bit system can process 32 bits in one cycle, similar a 64-bit system can process 64 bits in one cycle. The major difference is that in a 32-bit system you will be able to use only 2^32 bytes of RAM which is around 4GB. Similarly, for 64-bit systems, you can use up-to 16 Exa-Bytes of RAM. This is just the theoretical quantity, Even though there are these physical limits, Microsoft usually restricts the amount of usable RAM depending upon the software license you purchase. This is not a problem with Open source operating systems like Linux and BSD. 

 Software

 This is the most important thing. So if you run 32-bit system, you can only install software made for 32 bit systems. However, if you run a 64-bit system, you can run both 32 and 64-bit software as well. Most of the common software are made for 32 bits since it runs both places. But for some heavy software like image and video editing and rendering, a higher bit version is suggested because it will be able to use the processor and ram better.

 Conclusion


If you have a 64-bit processor and you installed a 32-bit system, you will be limited to using 4GB of RAM.
The number of bits in system reflects the number of bits its processor can process in a cycle. The more bits in your processor, the more RAM you can use. A 64-bit operating system will only run on a 64-bit processor. However, a 32-bit system may work on 32 or 64-bit processor. The same is applicable for software. It is still recommended to use software that are designed for your system type.

Quantization of Image Data Implementation in C#

Image
Introduction  This time we will share how to create an application to change the threshold value from black-and-white to the average value of the gray degree of all points and add textBox so that the user can change the threshold value according to the user's wishes. Besides that we also will add textBox to input quantization value. So the user can change the quantization as desired. Application Screenshoot A black-and-white image is an image that contains only black or white. Black is valued 0 and white is valued 255. To make the picture in black and white, the original color will be gray degree and each pixel will be compared with its threshold value. Normally, the black-and-white degree image has a 128 threshold value, so if the color value is less than 128, then the color is changed to 0 (black), and which is greater than or equal to 128 will be converted to 255 (white). Consider the example image below. Figure 1. The original image is predominantly dark When vi

Computer Graphics Project "Planet Orbit" Source Code with Glut OpenGL

Image
Hello there !!!  This time I will post a project in the past. It is about rotation and applied to make earth orbital with moon and sun. As reminder, for you who haven’t install glut you can download it in here and follow the instruction I uploaded too. You can download this orbital project in here too. The image above is the result of orbital project. Here is the source code for this project. #include <windows.h> #include <stdlib.h> #include <GL/glut.h> #include <math.h> void myinit() { glClearColor(0.0, 0.0, 0.0, 1.0); glColor3f(1.0, 0.0, 0.0); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(-400.0, 400.0, -400.0, 400.0,-400.0,400.0); glMatrixMode(GL_MODELVIEW); glShadeModel(GL_FLAT); glEnable(GL_DEPTH_TEST); } float putaransatu, putarandua = 0; typedef struct{ float x,y; } point2D_t; void drawDot(int x,int y){ glBegin(GL_POINTS); glVertex2i(x,y); glEnd(); } /*void bintang(void) { static int tick=0; static poi

Computer Graphics Project "MINION" Source Code with Glut OpenGL

Image
Hello !!! This time I post about computer graphics again. And yes, I will share a project which mainly used rotation and a little bit morphing. You can download this project here ( Download here to download glut and follow the instruction ) .The character used in this project is well known. Well here’s the depiction of this project. Minion !!! The eyes will rotate. And it’s smile will move up and down which give you a creepy smile hahaha.  So here’s the source code for this project : #include <stdio.h> #include <math.h> #include <GL/glut.h> #ifndef M_PI #define M_PI 3.141592653589793 #endif typedef struct { float x; float y; } point2D_t; typedef struct { float r; float g; float b; } color_t; ////////////// OpenGL drawShape Functions ver 1 ///////////////// void setColor(float red,float green,float blue) { glColor3f(red, green, blue); } void setColor(color_t col) { glColor3f(col.r, col.g, col.b); } void drawDot(float x,float y) { glB
