What do you mean by bandwidth/data transfer and space?
Answer
Bandwidth:-
Bandwidth means amount of data transferred in a fixed time
period. Generally bandwidth stated in bps (bits per second),
kbps (kilobits per second), or mbps (megabits per second).
Web hosting companies usually have different bandwidth plan
for their clients. You have to play within a limited bandwidth
and if cross that limit you will be charge for over usage
or they will make your site down.
The costing of your hosting plan varies on the usage of bandwidth
per month. If you run a commercial site you don’t need
much bandwidth. Your bandwidth usage goes high if you site
contain more files to download or number of user that visit
your site regularly. Ultimately if site have less html pages,
less images, and less files to download you need small amount
of bandwidth.
Disk Space:-
Disk space is basically amount of data store on the server
of your hosting provider. Web hosting company allocate some
amount of space to store data like files, directories, email
message, web pages, images, etc. Hosting provider give you
certain amount of space depends on your plan and whenever
it require you can modify your plan for more disk space.
Requirement of disk space depends on the file size of your
web site. If web site has only text content your requirement
for disk space will be very less but if your site contain
flash, images, media files, animation, etc your disk space
requirement will be more and also your bandwidth. To reduce
your file size you need to compress it before using them.
