Jaringan Komputer dan Internet
Komputer telah digunakan untuk mengkoordinasi informasi antara beberapa lokasi yang sejak tahun 1950-an. The US military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems like Sabre . Militer AS dari SAGE sistem adalah yang pertama dalam skala besar, contoh dari sistem seperti itu, yang menyebabkan sejumlah khusus-tujuan komersial seperti sistem Sabre.
Pada tahun 1970-an, teknisi komputer di lembaga-lembaga penelitian di seluruh Amerika Serikat mulai menghubungkan komputer mereka bersama-sama menggunakan teknologi telekomunikasi. dan jaringan komputer yang dihasilkan disebut dengan ARPANET. . Dengan teknologi yang menjadikan Arpanet kemungkinan menyebar dan berkembang. Dalam waktu, jaringan tersebar di luar akademik dan militer dan menjadi lembaga yang dikenal sebagai Internet. Munculnya jaringan yang terlibat redefinition dari batas-batas alam dan dari komputer. Komputer sistem operasi dan aplikasi yang telah dimodifikasi untuk menyertakan kemampuan untuk menetapkan dan mengakses sumber daya dari komputer lain pada jaringan, seperti perangkat perangkat, disimpan informasi, dan sejenisnya, sebagai ekstensi dari sumber-sumber kekayaan dari setiap komputer. Mulanya fasilitas ini telah tersedia terutama untuk orang-orang yang bekerja di lingkungan teknologi tinggi, tetapi pada tahun 1990-an penyebaran aplikasi seperti e-mail dan World Wide Web, dikombinasikan dengan pengembangan murah, cepat jaringan teknologi seperti Ethernet dan ADSL melihat komputer jaringan menjadi hampir ada di mana-mana. Bahkan, jumlah komputer yang sedang berkembang phenomenally jaringan. Yang sangat besar komputer pribadi secara berkala melakukan koneksi ke Internet untuk berkomunikasi dan menerima informasi. "Wireless" networking, sering memanfaatkan ponsel jaringan, berarti jaringan yang semakin ada di mana-mana bahkan di lingkungan komputasi mobile.
