The way CPU, NET and RAM power your Telos account are identical to EOS. The major difference for you as a user is lower resources cost. We cover the nature of these resources in detail in the EOS section, but to reiterate briefly:
CPU determines how much time a block producer will dedicate to processing your transactions.
NET is the bandwidth of your transactions, i.e. how much space can be allocated to them during processing.
RAM is your data storage cap for all information considering your account — ownership, keys, balances, etc.
