CRT

• Warna
• Monochrome
• Color : Red Green Blue (RGB)

Q: Menggunakan monitor monochrome dirasa sudah cukup


memadai daripada monitor color untuk keperluan:

a. Kasir mencari gambar dari database katalog barang


b. Mahasiswa menyusun neraca keuangan
c. Siswa TK belajar dengan komputer
d. Warga pedesaan mengakses situs web
e. Teleconference interaktif berbasis text
CRT

• Warna
• Monochrome
• Color : Red Green Blue (RGB)
• Pertimbangan memilih monitor:
• Size : panjang diagonal layar
• Resolusi: jumlah pixel
• Refresh rate : jumlah scan per detik
• Dot pitch : jarak antar dot RGB dalam 1 pixel
Display adapter

card, Video controller
Display adapter

• Display adapter, Video card, Video controller


• Jenis : VGA, SVGA, XGA
Display adapter

• Display adapter, Video card, Video controller


• Jenis : VGA, SVGA, XGA
• Jika ada n bit, maka jumlah warna: 2n
• Truecolor: 24 bit
• Ukuran memory: resolusi x n

Jika diinginkan menampilkan resolusi VGA (640x480) dengan 256 color, maka
berapa besar memory yang diperlukan?
256 = 28  memerlukan 8 bit = 1 byte/pixel
Jumlah pixel ada 640 x 480 = 307.200 pixel
Memory yang diperlukan = 307.200 pixel x 1 byte/pixel = 307.200 byte
Monitor LCD
• Passive Matrix,
• transistor ada di tiap baris dan kolom,
• supaya gambar jelas harus dilihat persis dari depan monitor.
• Refresh rate rendah
• Dual Scan, spt passive matrix tapi refresh rate 2x lipatnya
• Active Matrix, transistor ada di tiap pixel. Mengatasi kelemah passive
matrix
Printer
• Impact Printer
• Non Impact Printer
Printer
• Impact Printer
• bekerja dengan sistem “pengetukan”
• Kertas, pita, print head
• contoh:
• Dotmatrix : head berupa jarum (500 cps)
• Line printer : head satu baris huruf (3000 textlines/minutes)
• Band printer : pita huruf berputar (2000 textlines/minutes)
• Daisywheel : head berupa roda huruf (sperti mesin tik)
