Recently I have noticed that there are frequent communication difficulties caused from the technical wording. Often people can't distinguish between the basic terms and therefore I wrote this article to use it as reference material.
There are a few basic terms everyone who owns cryptocurrencies should know. It's much easier to get help if you can communicate with each other and understand the more technically versed people.
DeepOnion Wallet (DeepOnion-qt)
The standard wallet of DeepOnion. It allows to send and receive funds and is also a full node, which means it validates and secures the blockchain.

Full vs. Light Wallets
DeepOnion-qt is considered a full wallet because it needs the entire blockchain to be ready to use. Light wallets instead receive their data from a trusted source and download only as much as they need to be operable. Currently DeepOnion does not have a light wallet.
Hot Wallet vs. Cold Wallet
Hot wallets are connected to the internet and considered as 'possible' compromised. Cold wallets instead are typically created on an offline computer and the private keys are never exposed to the internet.
Hot wallet: DeepOnion-qt which is connected to the internet, Online generated paper wallet, ...
Cold wallet: DeepOnion-qt wallet or paper wallet generated on an offline computer and never used on an online computer. Sometimes hardware wallets are also called cold wallet.
Private Key
Your private key is used to sign transactions. This happens automatically by your wallet, which then broadcasts the transaction to the network. Every address have their own private key. It's recommended to have a backup from all your private keys.

Public Key
The public key is your wallet address. It is derived from the private key and as the name suggests it is intended to be public.
Wallet.dat
This is the file used by DeepOnion-qt. It stores all your addresses and private keys and therefore it is recommended to encrypt it and have multiple backups from it.
Password
The password which is used to encrypt your wallet.dat file. This is different from your private key and can only be used in combination with the wallet.dat file.
Transaction
When sending funds your wallet needs to create a string which holds all the information. This is called a transaction and contains at least the receiver, the change address, the amount and which input should be used. It looks like this.
Transaction Id
Every transaction has a unique Id which can be used to find it in your wallet or on every explorer. It looks like this.

Signing
Your transactions need to be signed to get accepted from the network. They are signed automatically by your wallet with the private key from the address.
Broadcast
Transactions are broadcasted to the network. This means it is send to all nodes of the network.
The above described terms should be the most important ones. If you would like to have additional terms explained, add them in the comments. Please let me also know when terms are hard to understand and I will update the explanation.
I published this article also on the DeepOnion community forum.
