Notes de l'éditeur

  1. Kebanyakan komputer untuk melakukan fungsi, ada tiga hal yang harus bekerja sama:
  2. Komputer ini hanya berguna untuk program atau aplikasi pd komp itu.
  3. Perangkat portabel bervariasi dalam ukuran, kekuatan dan kemampuan grafis dan meliputi: Laptop atau notebook PC Tablet PC Pocket PC Personal Digital Assistant (PDA) Perangkat game Ponsel Laptop juga dapat dipasang ke sebuah docking station yang memungkinkan pengguna untuk menggunakan monitor yang lebih besar, tikus, berukuran penuh keyboard danmemiliki pilihan koneksi yang lebih
  4. Komputer menggunakan kode biner untuk mewakili dan menafsirkan huruf, angka dankarakter khusus dengan bit. Sebuah kode yang biasa digunakan adalah American Standard Kode untuk Informasi Interchange (ASCII). Dengan ASCII, setiap karakter diwakili oleh string bit. Sebagai contoh: Modal huruf: A = 01000001 Setiap kelompok dari delapan bit, seperti representasi dari huruf dan angka, dikenal sebagai byte Ketika mengacu pada ruang penyimpanan, kita menggunakan istilah byte (B), kilobyte(KB), megabyte (MB), gigabyte (GB), dan terabyte (TB).
  5. Data Rate menentukan berapa lama waktu yang dibutuhkan untuk mentransfer file. Semakin besar file, lama waktu yang dibutuhkan, karena banyak informasi  untuk ditransfer. Kecepatan transfer data diukur dalam ribuan bit per detik (Kbps) atau jutaan bit per detik (Mbps).
  6. Random Access Memory (RAM)  penyimpanan sementara menyimpan data yang sedang diproses oleh CPU Mengapa pengguna membutuhkan lebih banyak RAM? Beberapa aplikasi yang berjalan pada waktu yang sama Beberapa CPU Jumlah RAM yang tersedia ditentukan oleh motherboard
  7. bagaimana data sampai ke lokasi
  8. Bila daya dihapus dari komputer, setiap data yang tersimpan dalam RAM akan hilang. Program dan data pengguna harus disimpan dalam bentuk yang tidak akan hilang ketika power akan dihapus. Ini dikenal sebagai non-volatile penyimpanan. Jenis non-volatile penyimpanan yang tersedia untuk sistem komputer termasuk: Perangkat penyimpanan magnetik Optik perangkat penyimpanan Statis memori (flash) drive Penyimpanan magnetik Ini menyimpan perangkat informasi dalam bentuk medan magnet. Mereka termasuk: Hard disk drive Floppy drive Tape drive
  9. Optical Drive Perangkat penyimpanan optik menggunakan sinar laser untuk merekam informasi dengan menciptakan perbedaan dalam kepadatan optik. Perangkat ini meliputi CD dan DVD yang terdiri dari tiga format yang berbeda: Baca saja: CD, DVD Tulis sekali: CD-R, DVD-R Menulis banyak: CD-RW, DVD-RW Statis Memory dan Memory Sticks Perangkat memori statis menggunakan chip memori untuk menyimpan informasi Karena ukuran dan bentuk, perangkat ini dikenal sebagai kunci memori USB atau flash drive
  10. Surge Protector   mencegah kerusakan pada komputer UPS (Uninterruptible Power Supply) menyediakan daya cadangan tanpa gangguan untuk waktu singkat
  11. Perbaikan Komputer Best Practices Matikan PC dan cabut listrik Menentukan apakah bagian hot-swappable (jika demikian, tidak ada kebutuhan untuk mematikan listrik sebelum menambahkan atau menghapus bagian) Jangan power supply terbuka atau monitor   keduanya mengandung tegangan tinggi Perhatian terhadap Electrostatic Discharge (ESD)   transfer listrik dari tubuh Anda ke bagian listrik
