many hosting website often say unlimited disk space and bandwidth,but anything is unlimited,i dont understand the meaning of unlimited,who can
explain it for me?
Unlimited means no limits right? But in hosting scenario that is not achievable practically. Always they apply some limits in other forms like CPU/RAM usage.
A lot of companies say that "unlimited" means you won't have to worry about xceeding x amount of space and bandwidth. But, if you use too much, often times people get booted for using too much of the hosts resources.
Still, you don't get an overusage fee. Some people were unlucky enough to be faced with thousands of dollars in overcharges when their site used hundreds of GBs more than allocated. Oops!
