Understanding The CAPTCHA

Understanding The CAPTCHA. Hi my brothers all! travel malang juanda As usual, because a lot of bustle would I very rarely post on the blog. Sorry well, hehe. This time I will share about the notion of CAPTCHA. For my brothers are hooked hanging out in KASKUS (, probably foreign udah gak again with the name CAPTCHA and perhaps also my brothers already knew about the sense of this CAPTCHA. Okay, without much further ADO, please read about the sense of my version of CAPTCHA:D

CAPTCHA image:

My brothers know not about CAPTCHA? CAPTCHA is a form of challenge-response test (challange-response test) are used in computing to ensure that the answers are not generated by a computer. This process usually involves one computer (a server) asking a user to complete a simple test which can be generated and graded by the computer. Because other computers are unable to solve the CAPTCHA, any user who can give the correct answers would be considered a human being. (source:

Still confused? So here goes, the core function of this is to make the CAPTCHA server (website) visited this only allowed for a human, not a robot or a computer that has been programmed to do a thing on the website or server (such as the content of a comment or click on auto on an ad).

For example, when the elder brother will post a comment or create a new Thread in KASKUS. Definitely going to appear a writing that is difficult to read. Well, it is useful to ascertain whether a computer that want to post a comment or thread on KASKUS is controlled by humans or robots/BOTS (computer which has been programmed). Usually BOTS are used in the posting amount to pursue KASKUS comment or thread to become ISO (can give reputation against a member).

There are various kind of CAPTCHA. From regular letters, to the mix of characters/of weird symbols that may not be contained in the keyboard. For this is a CAPTCHA created. Because it is typically a BOT/ROBOT can't fill the CAPTCHA's writings to be filled in. Well, despite the many ways so that the BOT can break through this CAPTCHA system. Please search on Google regarding BOT KASKUS.

To find out which words in the CAPTCHA, you should be careful. Since when is it wrong to type one character only, then the server system/website will send you enter CAPTCHA words.
Okeh, the articles this time about Understanding my version of CAPTCHA. Sorry, with all the flaws that exist in the article or on this blog. Input from the readers will be very helpful in the development of this blog. Thank You! :)

Understanding Kernel

Understanding Kernel. Hello my kitchen set malang brothers all! Ya Allah, udah jebot gak nih era of make-make a new article. Hehehe ... Sorry well now ya make a new article regarding the understanding of the Kernel. To think strange is also Yes, had been such a long blog and create a new caption, this time create a writing about the notions of Kernel. In fact, an important Kernel really known by all walks of Linuxer. Hahaha ...

Okay, without much further ADO, please read the article about Understanding my version:D Kernel

Image: the working structure of the Kernel of the operating system

The kernel is the heart or core of the operating system (OS) which serves to control the computer's system. The kernel is the bridge between the Software (application) with the Hardware on the computer. Many of the tasks that can be performed by the Kernel, such as memory management and multitasking. For more info, go to aja (ilmu_komputer):)

Still confused? So gini, a computer that's going to be really useful when there are three elements, Hardware, Software, and Brainware. The third element is able to communicate with each other. LOH, the human can communicate with the machine? Can kok, gan. But well, not direct communication robot language usage, gan. So that people can communicate with the machine (computer), people using the Software. Well, so that the Software can communicate with the Hardware of the computer, the unambiguous name of the operating system Kernel. The kernel is that bridges communication between Hardware with Software. That way, people can automatically communicate with the engine computer.

Still confused, too? Gini deh, for example agan want muter music using Amarok (Software) application. Of course if you want to listen to music would have been using speakers. Once agan go to file her Amarok, Amarok is telling the Kernel to issue the output form of the sound from the speakers. Well, certainly the work of the Amarok is easier because the Amarok does not need to know about the structure of the Hardware (PC) just to remove the output sound from the music being played because the task to communicate with the Hardware already supported by the Kernel.

The actual work of that Kernel weight. Because the Kernel connects all Hardware with Software. So the Kernel has also set up a resource that exists on the PC such as memory management (RAM) used by the Software, the result output to Hardware, software and also multiplexing.

So essentially, it is the core of the operating system responsible for regulating/bridging between the Software with the Hardware on the PC. Remember its structure, gan!
