All of the above<\/strong><\/p>\n<p>The front-end processor (FEP) is a dedicated processor that performs the following functions:<\/p>\n<ul>\n<li>Polling: The FEP polls the terminals to see if they have any data to send.<\/li>\n<li>Synchronization: The FEP synchronizes the data transfer between the terminals and the mainframe computer.<\/li>\n<li>Error checking: The FEP checks the data for errors before it is sent to the mainframe computer.<\/li>\n<\/ul>\n<p>The FEP is a critical component of a mainframe computer system. It provides the interface between the terminals and the mainframe computer, and it ensures that the data is transferred accurately and reliably.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Polling: Polling is the process of checking a device to see if it has any data to send. The FEP polls the terminals at regular intervals to see if they have any data to send to the mainframe computer.<\/li>\n<li>Synchronization: Synchronization is the process of ensuring that two devices are in step with each other.
