Ada tiga yang harus dipelajari

🔼One abstraction up: problem identification, problem solving, inquiry. Tujuan: mencari 'apa' yang harus dibuat.

▶️Middle layer yang masih tinggi valuenya hanya matematika, algoritma dan struktur data. Tujuan: mencari 'bagaimana' harus dibuat.

🔽One abstraction down: computer architecture, operating systems, networking. Tujuan mencari: batasan/konstrain fisik dari apa yang mau dibuat.
