Yuk..!!! Mengenal Web lebih dekat

Pastinya udah tau donk apa itu web/website, setidaknya pernah dengar lah istilah yang sudah tak asing ini.
contoh sederhana web itu www.facebook.com , halaman web yang paling sering di akses umat manusia sekarang ini.
yuk kita mengenal lebih dekat tentang bagaimana cara kerja suatu website.

pertama ada yang harus anda lengkapi terlebih dahulu untuk mengakses sebuah web :

1. User/Pengguna --> orang yang melalukan permintaan untuk mengakses suatu web. anda nggak usah binggung cari user kemana-mana, karena anda sendirilah user.
2. Browser -->  aplikasi yang berfungsi sebagai sebuah mesin pencari dimana sebuah situs atau informasi berada. kenal donk sama Mozilla Firefox atau Opera, nah itu contoh Browser.
3. TCP/IP --> standar komunikasi data yang digunakan oleh komunitas internet dalam proses tukar-menukar data dari satu komputer ke komputer lain di dalam jaringan Internet.
4. Server --> Pusat penyimpanan dan pengelolahan data. disinilah letak segala informasi yang ingin anda akses melalui web.
