I am trying to transfer .001 ETH from MyEtherWallet.com to an exchange, and while I realize I may not have enough to transfer, it mentions I need "GAS".

I tried reading and understanding the process, but it is still confusing.

I get the Error Message: Transaction gas is too low. There is not enough gas to cover minimal cost of the transaction (minimal: 21000, got:1). Try increasing supplied gas.

I type 21000, but I still get an error message.

How do I get to understanding GAS

Do cold wallets have to use GAS? ie) Trezor/Nano?

Gas act as a transaction fee
in every transaction there is always gas present or needed...
gas fees are not that high in price/ expensive, But in beginners part it is hard to have a gas when doing trading/transacting coins and tokens. It is because you don't have the deep knowledge about such thing..
It is wise to ask help from your seniors in this type of case..
On my first time making a transaction in EtherDelta i borrowed 5$ on my friend just to have gas and pay it when my coin/tokens got sold.
