• Apa itu Search Engine

Search engine disebut juga dengan mesin pencari, dimana sistem yang ada pada sistem tersebut diolah melalui satu atau sekelompok komputer yang berfungsi untuk melakukan pencarian data. Data yang ada pada mesin ini dikumpulkan oleh mereka melalui suatu metoda tertentu, dan diambil dari seluruh server yang dapat mereka akses. Jika dilakukan pencarian melalui search engine ini, maka pencarian yang dilakukan sebenarnya adalah pada database yang telah terkumpul di dalam mesin tersebut. Jadi dapat di simpulkan Searh Engine adalah Mesin Pelacak atau penelusur.


Search engine adalah sistem database yang dirancang untuk mengindex alamat-alamat website di internet . Untuk melaksanakan tugasnya ini, search engine atau mesin pencari memiliki program khusus yang biasanya disebut spider crawler. Pada saat Anda mendaftarkan sebuah alamat website (URL), spider dari search engine tersebut akan menerima dan menganalisa URL tersebut lalu mengcrawlnya.

Dengan proses dan prosedur yang serba otomatis, spider ini akan memutuskan apakah web yang anda daftarkan layak diterima atau tidak pada search engine tersebut. Jika layak, spider akan langsung menambahkan alamat URL tersebut ke sistem database mereka. Rangking-pun segera ditetapkan dengan algoritma dan caranya masing-masing. Jika tidak layak, terpaksa Anda harus bersabar dan mengulangi pendaftaran diwaktu yang lain. Jadi semua yang namanya search engine, pasti memiliki program yang disebut Spider crawler. Dan program inilah yang sebenarnya menentukan posisi web site Anda di search engine tersebut.

Contoh beberapa search engine terkenal adalah : Altavista, Google, Excite, Northern Light, Hotbot, dan masih bayak lagi. Berbeda dengan web directory yang meng-index halaman website di internet secara manual. Manual yang dimaksud adalah mereka menggunakan orang biasa untuk menganalisa setiap halaman web yang masuk. Tidak menggunakan spider atau crawler seperti halnya search engine. Keunggulan directory dibanding search engine adalah memberikan hasil pencarian yang lebih relevan dengan kualitas yang relatif lebih baik. Tapi karena semua proses dilakukan secara manual (menggunakan editor manusia), jumlah database yang dimiliki bisasanya jauh lebih kecil dibandingkan dengan search engine.

Itulah sebabnya sekarang ini banyak perusahaan yang mengelola directory menerapkan sistem ganda, yaitu menggunakan directory + search engine. Contoh nyata adalah Yahoo yang menggandeng Google sebagai search engine default-nya. Contoh beberapa directory terkenal selain Yahoo adalah Open Directory Project, Looksmart, dan NBCi.
Sekarang udah ngertikan apa itu Serach engine, Mesin Pencari, alias Mesin Penelusur





Kini hampir setiap hari orang menggunakan google untuk mencari web yang mereka inginkan. Google sudah menjadi web wajib yang harus dikunjungi setiap kali tersambung k internet. Tidak salah memang google yang merupakan kata dari salah penulisan kata googol yang berati sangat besar sekali, kini menjadi mesin pencari yang memang besar sekali.

Google sendiri awalnya dibuat oleh dua mahasiswa hingga menjadi sedemikian besar sebagai suatu bisnis. Penemu sekaligus pemilik google kini menjadi orang kaya didunia.

Mesin pencari lain yang tak besarnya adalah yahoo. Yahoo walaupun masih diabawah google dia lebih tua dari google. Yahoo selain mesin pencarinya juga sangat terkenal dengan layanan emailnya dan tentunya yahoo mesenger.

Mesin pencari yang di miliki microsoft adalah mesin pencari bing yang saat ini menampilkan gambar-gambar alam yang begitu mengesankan sebagai daya tariknya untuk menyaingi google.

Namun dari sekian banyak mesin pencari, google masih memimpin dan Google pula satu-satunya mesin pencari yang menggunan pagerank.

• U.S. news, UK, Singapore, and Indonesia

In developing countries like America, Britain, Singapore, and Indonesia for example, coronary heart disease is one of pengancam human soul that is still very rampant in addition to other epidemics such as avian influenza or a natural disaster.
It has been a lot of people who died of this disease, and operating costs to cure patients of coronary heart disease is also very expensive. Although the disease generally attacks people who are relatively old enough, around the age of 50 years and upwards, we must not relax our vigilance and our knowledge of coronary heart disease, since this disease originated from the negligence of us when we were young.
Coronary arteries are blood vessels that supply the heart with blood. The coronary arteries were more specifically provides that there is oxygen-oxygen in the blood to the muscle - heart muscle found in the heart wall. This is especially need to be maintained for a person to survive because the oxygen-oxygen will be used for the respiration of heart muscle for the heart to continue pumping blood throughout the body.
If the oxygen-oxygen can not be channeled properly to the heart muscles, the heart will become weak and unable to provide blood to all parts of the body. As a result, the person will die because of biological processes within itself can not be done because the organs of the body does not get the nutrients and oxygen from the blood.
In coronary heart disease, coronary arteries become increasingly narrow and sometimes blocked. This causes the blood can not be channeled properly to the heart muscles. At this early stage, perhaps the patient can still breathe normally and blood flow to the heart muscle is still pretty.
However, when he made the exhausting activities such as exercise or scold other people, the narrowed coronary arteries can not supply enough blood to the heart muscles. In fact, at present, the heart requires more blood for the body to get enough energy to do an activity that was exhausting. The sufferer can fall unconscious and unconscious, and even can be directly passed away.
Narrowing of the coronary arteries is usually called arteriosclerosis, and one form of arteriosclerosis is narrowing because of saturated fat, which is called atherosclerosis. In this process, fats build up in arteries and thickening of the wall produces a rough surface on the walls of the arteries and narrowing of the coronary arteries.
This makes the possibility of blood clots in the arteries that narrows it. If the blood continues to clot, then no more blood can flow because the blood is blocked by a blood clot that had become hard.
If there is no more blood can flow through the coronary arteries, then the patient will experience a heart attack. At this stage the patient is unable to continue aktivitinya and would fall limp because there are parts of the heart muscle that has died because of not getting enough blood.
Patients who had a heart attack need to be immediately taken to the hospital and get treatment immediately, such as providing oxygen for him not to enter a critical phase. However, if part of a dead heart muscle is very large, the impact experienced by the person will be very fatal, and can bring that person to death.
Therefore, since our youth should avoid fatty foods such as animal fats. This animal fat is saturated fat and should be replaced with plants that are not dangerous.
In fact, plant fats can lower cholesterol levels in the blood and if we often do not exercise and has high blood pressure, then our chances of coronary heart disease is very small.
