Fakta di balik browsing…

Ketika kita sedang browsing dan mengetikkan http://www.google.com di browser dan kemudian menekan tombol Enter, selang beberapa detik kemudian, JEBRET!, muncul halaman utama Google.
Apa yang terjadi pada selang beberapa detik itu? Bodo amat. Saya tidak tahu dan tidak ingin tahu.

Ehm, begini ceritanya…
Saya copy-paste aja dari ebooknya.
The networking industry has a standard seven-layer model for network protocol architecture called the Open Systems Interconnection (OSI) model. The OSI model represents an effort by ISO, an international standards organization, to standardize the design of network protocol systems to promote interconnectivity and open access to protocol standards for software developers.

The seven layers of the OSI model are as follows:

Physical layer— Converts the data into the stream of electric or analog pulses that will actually cross the transmission medium and oversees the transmission of the data.

Data Link layer— Provides an interface with the network adapter; maintains logical links for the subnet.

Network layer— Supports logical addressing and routing.

Transport layer— Provides error control and flow control for the internetwork.

Session layer— Establishes sessions between communicating applications on the communicating computers.

Presentation layer— Translates data to standard format; manages encryption and data compression.

Application layer— Provides a network interface for applications; supports network applications for file transfer, communications, and so forth.

Dan browser, semacam Internet Explorer dan Firefox, berada pada layer Application.
