Correct option is B
An Intelligent Terminal is a device that has its own memory, processor, and firmware that allows it to perform specific functions independently of the host computer. These terminals can process some data locally before communicating with the mainframe or host, making them capable of performing tasks without requiring continuous connection to a central computer.
Important Key Points:
1. Intelligent Terminal - Unlike a dumb terminal, an intelligent terminal can perform tasks such as editing, buffering, and processing data due to its onboard processing capabilities.
2. Autonomy - The presence of firmware allows intelligent terminals to be partially independent, making them more versatile in various operations.
Knowledge Booster:
• Dumb Terminal: A dumb terminal has no processing power of its own; it is completely dependent on the host computer to process and display information.
• Firmware: Intelligent terminals contain firmware, which is embedded software that helps them to perform some functions autonomously.
• Local Processing: Intelligent terminals can handle local processing tasks, such as simple data manipulations, before sending information to the central computer.
