Karena tekanan di atas dan di bawah sayap itu berbeda (tidak seimbang), ketidakseimbangan inilah (net unbalance) yang menciptakan gaya aerodinamika (seperti lift atau ga..." current

UART itu cuma butuh dua kabel utama (selain Ground): *TX (Transmit): Jalur buat ngirim data. *RX (Receive): Jalur buat nerima data. Kabel TX di microcontroller harus disambung ke kabel RX di perangkat lawan, dan sebaliknya." current

Keduanya membahas paralelisasi, tapi dari sudut pandang yang fundamental berbeda. Gustafson's Law menyatakan bahwa seiring bertambahnya jumlah prosesor, kita cenderung mengerjakan tugas yang lebih besar dalam waktu yang sama, bukannya mengerjakan tugas yang sama dalam waktu yang lebih cepat. Gustafson berargumen kalau asumsi itu tidak realistis. Di dunia nyat..." current
