Most common:
Use TACACS+ to control what administrators can do on a device. Use RADIUS to authenticate users and devices onto the network.
TACACS+ encrypts all communications using TCP port 49.
RADIUS only encrypts the password and uses UDP ports 1812 for Authentication and 1813 for Accounting. Some implementations of RADIUS use ports 1645 for Authentication and 1646 for Accounting.Master of Business Administration in Information Technology Management - Western Governors University

it is for central administration of user access, authorization, and accounting. -

Tacacs+ uses tcp port 49
Is cisco proprietary
Encrypts the entire payload
Separates each aaa function
Geared toward device administration
Can authorize individual commands
Supports message passing, additional challenges besides login/password can be presented
Notifications can be displayed such as custom banners for different types of events
Radius uses udp port 1812 and 1813 (accounting)
Encrypts only the password field
Combines authentication and authorization
Geared toward network access
Authorization is all or nothing -

For managing Cisco products only, you will prob see TACACS+ more. But there are many non Cisco and legacy devices that only support RADIUS for user management so in a mixed environment sometimes you don't have a choice, or you use both.
Also service providers will use RADIUS to authenticate DSL and what's left of dial-up users.[X] CCENT ICND1 100-105
