Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is pretty much like cash for the Internet. Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence.

Bitcoin Basic Concepts

Bitcoin is a shared ledger.  It is essentially a spreadsheet that shows how many bitcoins each account contains.  All the complications come from the need to make sure it is valid and everyone see the same ledger.
 The current state of the ledger is determined by a decentralized and trustless consensus.  It cannot be controlled at any central point.
Bitcoin “mining” is the process of adding transactions to the ledger and is done by solving math problems that take substantial computational power.
The “consensus” is achieved by users and “miners” deciding to run compatible versions of the software and enforcing the consensus rules.
Users can run “nodes” using peer-2-peer connections that shares the ledger.  By running a full node a user can completely verify all transactions without the need of a third party service.
Nodes enforce the rules by only broadcasting transactions and sections of the ledger that fit within the consensus rules.
A user can easily verify the shared ledger took a huge amount of computational power to create as a way of trusting it is real.
Miners get transaction fees and “block rewards” as an incentive to use their computer power.
The “block rewards” are a way to initially distribute the currency and are cut in half about every 4 years until all 21 million bitcoins are distributed in 2140.  Due to the nature of “halving” most bitcoins are distributed during the first few halvings.  It was 50 Bitcoins for the first 4 years and is currently 25 Bitcoins.  In 2016 it will be 12.5 and in 2020 it will be 6.25.
Bitcoin addresses are secure because the numbers are so large that all the computers in the world cannot come close to cracking it.
A Bitcoin can be broken down to 8 decimal digits so each one has 100 million pieces.
A Bitcoin transaction can be used to indirectly store information in the permanent shared ledger without trusting a third party.

For quick understanding, consider Bitcoins as Coins in the form of bits (010101.......). Yes it is a digital currency with a promising future.
