  1. Mata Kuliah : Bahasa Rakitan Materi ke-2 Sistem Bilangan

  2. SISTEM BILANGAN • Sistem Bilangan Desimal • Sistem Bilangan Biner • Sistem Bilangan Oktal • Sistem Bilangan Heksadesimal

  3. Sistem Bilangan Desimal • Basis 10 • Bilangan : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

  4. Sistem Bilangan Biner • Basis 2 • Bilangan : 0, 1

  5. Pengelompokan Biner : • BIT (B) = 1 Bilangan Biner • Nibble = 4 Bit • Byte (B) = 8 Bit • Word (W) = 16 Bit • Double Word = 32 Bit • Paragraf = 128 Bit • Page = 256 Byte = 2048 Bit

  6. Pengelompokan Biner : Word (W) = 16 Bit • MOST SIGNIFICANT BYTE (BIT Ke 8 S/D 15) • LEAST SIGNIFICANT BYTE (BIT Ke 0 S/D 7) x x x x x x x x x x x x x x x x _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 15 … …9 8 7 6 5 4 3 2 1 0

  7. Sistem Bilangan Oktal • Basis 8 • Bilangan : 0, 1, 2, 3, 4, 5, 6, 7

  8. Sistem Bilangan Heksadesimal • Basis 16 • Bilangan : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F

  9. Bilangan Bertanda • Sandi Bilangan Bertanda • Letak Sandi

  10. Bilangan Negatif Mencari Bilangan Negatif : • Konversikan bilangan desimal negatif menjadi bilangan biner positif. • Komplemenkan setiap angka 1 dengan 0 dan angka 0 dengan 1. • Tambahkan angka satu pada bilangan hasil komplemen di atas.

  11. Sandi ASCII • ASCII = American Standard Code For Information Interchange. • Salah Satu Bentuk Baku / Standarisasi Sandi Dalam Mikro Komputer. • Sandi ASCII Terdiri Dari 128 Sandi.

  12. Sandi ASCII (cont.) • Kelompok 8 bit (1 byte)  28 = 256 bilangan • Satu Bilangan = 1 sandi ASCII • 128 sandi ASCII = 128 bilangan  00 H s/d 7F H • Character set lainnya = 128 bilangan  80 H s/d FF H
