Performance+Factors

Introduction
We have all experienced times when accessing the Internet seems slow or even unavailable. Often people say that "the Internet is down", but of course the Internet is not down. So what can be the cause of these performance issues?

Problems on the client side
Copy the diagram below



Label the diagram with the following points which could impact on performance

1. Speed of internet device (Computer, game console, mobile device) 2. Speed of modem / router 3. Transmission fault - network cable unplugged

Problems on the server side
Copy the diagram below



Label the diagram with the following points which could impact on performance

1. Speed of server 2. Too many requests at one time (concurrent requests)

Broadband versus Dial-up

 * Speed of internet connection is measured in Megabits per second Mb/s
 * Dial-up is provided across telephone lines by ringing through to a dial-up server
 * Broadband is delivered across cable lines or via satellite
 * Broadband is constantly on, dial-up is only one once the connection has been made
 * Broadband is faster than dial-up
 * Broadband is more reliable than dial-up

Task
Investigate the difference between broadband and dial-up connections, and in particular the difference in connection speeds. Create an animation using Xtranormal, GoAnimate! or a similar application to explain the difference between broadband and dial-up.
