DATA TRANSFER

The Internet is a globally distributed data storehouse. A PC which isn't networked loads data from the hard disk into memory and displays the contents of the file on the screen (left in the following diagram). A PC connected to the Internet is linked to many other computers and can download data from remote computers directly into memory to display it on-screen or save it to the hard drive.

The transmission speed of files from all over the world to your PC mainly depends on the "baud rate" you are using. This is an example to demonstrate how long the loading of various files requires when using a normal modem over your phone line, a fast modem (28.2 kbps), or an ISDN connection (57.6 kbps). The abbreviation "kbps" stands for: kilobit per second, i.e. one thousand computer signals (0 or 1) in one second. Thus, 14.4 kbps means that 14.4 * 1000 computer signals or 1840 letters can be transmitted each second.
