• Backing up computers over the network has become popular due to the availability of
inexpensive mass storage. Table 6-1 shows approximate, comparative times for transferring 1
gigabyte (1 GB) of data using various networking technologies.
Optimizing Your Network Bandwidth
As your network grows, it might consist of several segments of different networking technologies,
each providing different throughput. In planning your network, you should first consider which
devices will have the heaviest traffic flow between them. Examples are:
• A media center in one room streaming high-definition video from a server in another room
• A storage device that is used for backing up your computers
