Berpikir komputasional

 Halo semuanya

nama saya haniah dwi lathifah dari kelas 9.7 membuat blog tentang salah satu materi informatika, berikut blog saya.

berpikir komputasional itu cara berpikir yang dipakai untuk menyelesaikan masalah secara logistik dan sistematis, mirip seperti cara kerja komputer dalam memecahkan suatu permasalahan. tapi ini bukan berarti kamu harus bisa berpikir dulu, ya~ berpikir komputasional lebih ke cara berpikir daripada cara memprogram.

Biar lebih jelas, berpikir komputasional biasanya mempunyai 4 komponen utama, yaitu:

1. dekomposisi (penguraian)

➜ Memecahkan masalah besar menjadi bagian-bagian kecil agar mudah diselesaikan.

contoh: kalau kamu mau membuat game, kamu pecah dulu jadi bagian — desain karakter, atur skor, buat level, dst.

2. pengenalan pola (pengenalan pola)

➜ mencari kesamaan atau pola dari berbagai masalah biar kita bisa menggunakan solusi yang mirip.

contoh: kalau kamu sudah bisa membuat game puzzle, kamu bisa menggunakan logika yang sama membuat game teka-teki lain.

3. abstraksi (abstraction)

➜ fokus pada hal-hal penting saja, buang detail yang tidak perlu.

contoh: kalau kamu mau membuat program cuaca, kamu cukup fokus pada suhu dan kelembapan, tidak perlu detail seperti warna awan.

4. algoritma (algoritma)

➜ langkah-langkah sistematis untuk menyelesaikan masalah.

contoh: resep masakan juga termasuk algoritma — ada urutan langkah dari awal sampai selesai.

jadi intinya, berpikir komputasional bikin kita bisa menyusun solusi yang efisien, terstruktur, dan mudah dipahami, kayak komputer memproses data gitu

myth Surrounding World Mobile Phones

Around us a lot of myths developed, the issue will lead to the brain trust, in the event that there is not yet proved his card. Not surprisingly, a myth has always been pro-contra never stop. World provider did not escape from the issues italics.

Is alert, with the information that is not necessarily correct, we may mistakenly take the decision. So we must be more subtle and circumspect in responding to the myth, this myth. about what the issues are debated in the cellular world at this time.

Mobile phone used in the Food And Drug Control gasoline can cause explosion

Until now, not ever happen in the Food And Drug Control explosion of gas caused by the use of mobile phones. Prohibition of the use of mobile phones in the Food And Drug Control itself more on gasoline concerns will disrupt the system literan most of which are fully digital.

Phone signals can be offending aircraft navigation system

According to research, mobile phone signals can be spread through the slit / window and then creep up to an antenna on the plane and the radar, navigation equipment, and others. However, according to NASA and the FAA have not yet found evidence of a plane accident caused by a signal issued by a mobile phone, although some pilots think otherwise.

Using a handsfree can reduce the radiation

By using the handsfree is not the level of radiation is reduced, but the directions are moved and stray from the head. Radiation own strong spread around the antenna, using a handsfree phone with a distance of the ear to become more so it can minimize the effect of radiation.

Mobile phone radiation can cause cancer

This issue is still debated. According to research by the Institute of Cancer Research has not found cases of cancer caused by the use of mobile phones, but they said the radiation effects can cause this disease.

Phone stored in the pocket will reduce the quality of sperm

It refers to the opinion of a research in a clinic in Ohio. Here, if someone is using the phone more than 4 hours a day, the number of sperm appeared to have fewer number of sperm with good quality less. Results of this research is still in question because not consider other factors such as the use of drugs.

SMS cheaper than calls
Recently many operators to offer promotional fares where the price of a call is very cheap, even free. Particularly call to fellow operators, communicating through voice may be felt more efficient.

Rates from cheaper CDMA GSM

Now this is cheap GSM tariffs, even dare to offer one rupiah per minute. Compare with the price of calling cards with CDMA is the average of 50 rupiah semenit. However, should the numbers scheme penarifan GSM is the sometimes complex, and the time limit campaign.

Telephone day only pay one minute

No person may be able to call the day without end, in addition to power the device (mobile phone) that is not possible, who was the usual chitchat full day in a one-time connection. According to some research data obtained average call only 3 minutes only. Bonus call duration can be only as a campaign tool only.

Internal antenna signal weaker

Actual power the phone catching more dependent on the quality of the signal emanating from the BTS and the areas where the phone is located and the characteristics of the antenna itself. While the location of the antenna is not too strong influence of weak signal significantly.

Filling the battery must be done when the battery is exhausted

Each type of battery has its own characteristics, for the type of battery and Lithium Polymer battery can be charged before the really low. While the battery of Nickel and NiMH batteries must be filled when empty because it has the memory effect is permanent, given the position of zero energy that occurs when charging.

Ampere battery with a large can survive for long

Not necessarily, other than the affected ampere capacity, power a mobile phone battery affected by many factors, such as the type of processor used, operating system, color screen, and others. The many components of the power suck the battery power even more profligate.
