To keep track of what is going on in the system CICS uses several different control blocks. Most of these control blocks are dynamically managed. They are created when needed and disposed of when no longer needed. Primarily CICS management modules access the Control blocks. They provide various kinds of information.

For example,

A control block called Task Control Area (TCA) represents each transaction.

Information about current task is stored in to control block named Execute Interface Block (EIB).

Thanks & Regards,
