This is a classic technical question. It first asks you to define two terms used in your profession and then to discuss their function. This is the same format you should use when responding to the question. Keep your answer brief and to the point, and anticipate a follow-up question that the interviewer will use to delve deeper into the topic. If they ask a follow-up question, it indicates that the topic may be important to their operations.

"Terminal Access Controller Access-Control System, or TACACS, is a remote authentication protocol used to communicate with an authentication server commonly used in UNIX networks. TACACS allows a remote access server to communicate with an authentication server to determine if the user is authorized to access the network. Remote Authentication Dial-In User Service (RADIUS) is also a protocol for controlling access to a network. Internet service providers and companies commonly use RADIUS to manage access to internal networks across several technologies, including modem, DSL, wireless, and VPNs."
