Tabel ASCII
Ini adalah fakta yang sangat terkenal bahwa komputer hanya dapat mengenal data berupa 0(mati) dan 1(hidup). Dengan mengurutkan bilangan 0 dan 1 sebagai terjemahan biner ini maka kita dapat mengungkapkan nilai-nilai numerik.
Namun demikian tidak ada cara yang jelas untuk mewakili huruf dan karakter non numerik lainnya. Oleh karena itu, agar komputer dapat mengenal huruf dan karakter tersebut komputer menggunakan ASCII Table. Tabel ini berisi semua huruf dalam alfabet ditambah beberapa karakter tambahan. Dalam tabel ini masing-masing karakter selalu diwakili oleh “nomor urutan” yang sama. Sebagai contoh, kode ASCII untuk huruf kapital “A” selalu diwakili oleh urutan 65 yang mudah representable menggunakan 0 dan 1. Dalam biner: 65 dinyatakan sebagai angka biner 1000001.
Ada 256 Huruf dan Karakter dalam ASCII Table, dimana keseluruhannya dibagi menjadi 3 bagian yaitu:
