In a shared hosting environment, the amount of server disk storage allocated to your account is known as the diskspace. This space can be used to store HTML and graphics files, programs or scripts, email messages, compressed files, or other files that make up your web site. Diskspace is expressed in megabytes (MB).

The amount of space on the server that is available to your websites

This refers to the amount of space you can use on a host's computer. The size of all the files on your website cannot exceed the total amount that you are allowed. It is usually measured in MB, and sometimes in GB. (1GB=1000MB= 1,000,000 KB= 1,000,000,000 Bytes)
