Significance of a Terminal Control Table (TCT) - CICS Interview Question

A Terminal Control Table (TCT) in CICS is a vital component that stores information about terminal devices connected to the CICS region. It holds details such as device type, device address, and associated applications.

The significance of a TCT lies in its ability to facilitate efficient and controlled communication between CICS and terminal devices. By maintaining a centralized repository of terminal configurations, the TCT helps in managing device interactions, optimizing system performance, and ensuring seamless user experiences.

Understanding and effectively utilizing the TCT can lead to enhanced system reliability, improved resource allocation, and streamlined troubleshooting processes in a CICS environment.
