What are the different tables(Engine) present in MySQL, which one is default?

Following tables (Storage Engine) we can create
1. MyISAM(The default storage engine IN MYSQL Each MyISAM table is stored on
disk in three files. The files have names that begin with the table name and have
an extension to indicate the file type. An .frm file stores the table format. The data
file has an .MYD (MYData) extension. The index file has an .MYI (MYIndex)
extension. )
2. InnoDB(InnoDB is a transaction-safe (ACID compliant) storage engine for
MySQL that has commit, rollback, and crash-recovery capabilities to protect user
data.)
3. Merge
4. Heap (MEMORY)(The MEMORY storage engine creates tables with contents
that are stored in memory. Formerly, these were known as HEAP tables. MEMORY
is the preferred term, although HEAP remains supported for backward
compatibility. )
5. BDB (BerkeleyDB)(Sleepycat Software has provided MySQL with the Berkeley
DB transactional storage engine. This storage engine typically is called BDB for
short. BDB tables may have a greater chance of surviving crashes and are also
capable of COMMIT and ROLLBACK operations on transactions)
6. EXAMPLE
7. FEDERATED (It is a storage engine that accesses data in tables of remote
databases rather than in local tables. )
8. ARCHIVE (The ARCHIVE storage engine is used for storing large amounts of
data without indexes in a very small footprint. )
9. CSV (The CSV storage engine stores data in text files using comma-separated
values format.)
10. BLACKHOLE (The BLACKHOLE storage engine acts as a "black hole" that
accepts data but throws it away and does not store it. Retrievals always return an
empty result)
